Typing enhance efficiency: Win10 Mobile keyboard input Skills 11

The keyboard is one of the important tools we use every day when computer or mobile phone, to master some skills can improve our typing efficiency. This article summarizes 11 kinds applicable to Win10 Mobile touch keyboard input skills and see if you have a full grasp.

1, tap the spacebar twice in a row ending a

In fact, this technique is for English input, when you write a word when hitting the spacebar twice in a row at the end of the sentence can automatically add a period and a space represents a word has ended. Of course, you can also click and then click the box next to a full stop, but no doubt a continuous double-click the box more convenient.

2, sliding enter numbers or symbols

Usually when we enter a number or symbol, will press the button at the lower left corner of the keyboard symbol to switch to symbol input, the input even after the switch back. In fact, you can hold down the button and slide symbol or symbols you need to select the digital input, the keyboard will give the current option prompt, enter after completion will automatically switch to the previous panel.

3, sliding input common punctuation

The same applies to sliding input punctuation input. For example, when you press the eject button ending punctuation selection prompt, you can directly select the input sliding around punctuation.

4, sliding input .org, .edu, or. Net and other URL suffix

We need to enter the URL in place, such as Edge browser address bar will automatically call the keyboard keys with .com. Press and hold URL suffix will pop up frequently used options, then you can select the input slide.

5, press the Shift key to lock the case status

If you need to enter a long string of capital letters how to do? Press the Shift key (arrow up, namely Shift) default will only make the first letter of the next to uppercase. At this point you can press the Shift key to lock the keypad of the case status.

6, using the precise positioning rod

Win10 Mobile Keyboard comes with a precise positioning rod, do not ignore its existence, you can use it to pinpoint the location of the cursor, in order to enter the middle of the missing character content.

7, add words to the suggestion list

Windows10 Mobile keyboard when you're typing words may give advice over the keyboard, if a word is your favorite but did not appear in the proposed list, you can add their own. Enter e-mail or OneNote applications that vocabulary, position the cursor to the top of this vocabulary, click the plus sign above the keyboard can be added to the recommended list.

8, will be moved to the left or right side of the keyboard

For regular typing with one hand friend, will move to the side of the screen keyboard seems to be more convenient. Press & 123 keys on the keyboard, and then select the keyboard icon, the keyboard will have the option to move one side of the pop-up options. This feature seems to only 5 inches above the device will have.

9, the keyboard up or down

Keyboard not only appear in the bottom of the screen, you can press the spacebar and then drag it up or down. This feature also seems to apply only to 5 inches above the device.

10, the slide switch the keyboard

We can press & 123 button to switch and add a new keyboard, relatively fast keyboard switching method is sliding around the space key.

11, the use of voice input

Without disturbing others, the voice input efficiency than manual typing faster. Press the microphone button above the keyboard to try voice input bar. (Via: WindowsCentral)

How to Open a Laptop Power Supply

Your computer suddenly doesn't power on. No matter how much you wiggle the laptop power supply cord or attempt to let it charge, the computer still acts dead. To determine the culprit behind your power supply problem, you may need to open it up for inspection.

Things You'll Need

Laptop Power Supply (AC Adapter)

Knife

Hammer

Instructions

1.Turn off your laptop and unplug the power supply. The power supply, also known as
an AC power adapter, is the unit that you connect to your computer and plug
into the wall. This is not the battery that is found latched inside your laptop.

2.Place the power supply on a flat surface.

3.Turn the power supply on its side and place the knife in the seam of one of the edges. This seam is the crease that separates the top and bottom casing. You may need to wiggle the knife into the crease by motioning it from side to side. All power supplies will have a top and bottom casing that can be separated (PC and Apple).

4.Tap the knife with the hammer three to five times until you feel the case start to loosen. You may need to apply a little force with each tap.

5.Flip the power supply over and repeat Step 4 on each additional side. On the second side, you will feel the case open up slightly. By the fourth side, the case should loosen up and you may hear a pop.

6.Pull the case apart gently, and your laptop power supply is now open for inspection.

Laptop manufacturers deliberately shorten the useful life of laptop

Recently, a question was raised in the US social networking Q & A site Quora: the laptop is not intentionally designed not durable? A man named Jeff Kay (JeffKay) communities technician gave his answer:
This question has two answers. First, on the whole, the laptop PC designed from the start and hope obsolete within a fixed period of time. In other words, firms developing these products have been worked out a plan: After a period of time, these products will be a problem, you either pay for costly repairs, or forced to buy a new machine.
Some brands may indeed do so. However, reducing the useful life can generate income in the short term, but long term there may be counterproductive.
For example, Dell apparently very durable, but every time you will find that a few years after Dell can not be reused, and the problem often lies in the power supply. Either a bad transformer or a bad motherboard bus. The former high cost if purchased separately, the latter must replace the motherboard, so they need Depot Repair. In either case, the warranty period will be over soon.
The existence of two issues this business model. On the one hand, this may force the user to purchase a laptop in advance, but may not choose your brand again. On the other hand, many people will regularly buy a new laptop, it may be a year or two, some people may spend three years or longer (the longest warranty period is only 3 years) will buy a new machine. And the replacement down the old laptop may be someone else or foreign sales, but these users get old computer after a failure, but not likely to purchase a new computer.
In other words, these old computers simply do not come with any new business, it will only damage the reputation of the brand.
I have some old laptops used for many years, one of which is a four-year Acer. In addition to a keyboard replaced because water, plus the battery life time by a few minutes, but it never had any problems. I had to buy this Acer spent less than $ 300. Recently bought a Toshiba laptop, I sent her daughter. Compaq laptop because she had already spent seven years, so this is a "new" computer made her very happy. Compaq is now my Plex server, which makes our whole family can watch videos on Roku.
Since the birth of laptop, lighter, thinner is the mainstream trend. Now the new models are thin, very light, but it will therefore compromise in terms of body strength.
Focus point if you open the laptop in the corner of the screen when it is possible to damage the screen. But this is mainly because of design limitations, rather than intentional. In addition, the replacement of the screen is much cheaper than replacing the motherboard, it is much easier to find video clips from YouTube will be able to learn.
Analogy spectacles. Every time I buy a new pair of glasses, the optician will recommend I wear glasses and want to use both hands when you pick glasses, avoid frame bending or have other damage. Because not listened to advice, I've paid a lot of tuition.
Open laptop should follow the same advice to hand on the center, not on the corner, which prevents uneven force. Of course, it is easy to give advice, but who actually did but not much - people will inevitably of convenience.
The same is true when using the CD-ROM drive, it is best to withstand the tray with one hand, then the other hand to release the disc.
Some computer companies do damage deliberately set the stage, but will not do tricks in the structural design. However, these companies or because of this little trick and gradually alienate old users. Over time, sales will certainly decline.

Laptop keyboard can not be used solutions

First, why not use the keyboard
Computer keyboard can be said to be in daily use, contact one of the largest interactive devices and users, often the kinds of problems now, the keyboard can not be used in a wide variety of phenomena often bring problems to users. Let the user to use, you may encounter the keyboard can not be used to analyze the phenomenon.
1, the cable can not be used Keyboard

Keyboard keyboard cable break will cause intermittent failures
Many users daily use, you will find all the keyboard keys suddenly invalid, the keyboard status lights go out at the same time along with key failure. Users move the keyboard, or the restart after the keyboard and can return to work. This phenomenon can not be the main reason for the keyboard, the keyboard cable is often repeated bending or aging, causing internal cable breakage virtual access, such as a strong player ability, you can try to replace the keyboard cable to resolve.
2, the main failure resulting string key can not be used

Master chip failure resulting string key phenomenon
User process, we will encounter the phenomenon of serial key can not be used. After the performance for the user to press a key, the key input response of other keys. For example, press the "A" key, "B" letter, which is due to the internal keyboard controller chips, code libraries caused problems. Manufacturers can re-flash the firmware to fix string key phenomenon. Ordinary users can not repair themselves. If the failure is still under warranty keyboard, you can point to a repair maintenance and replacement, if you have had insurance, only to re-purchase.
Second, the keyboard can not be used for reasons
3, a single keyboard can not be used

Film circuit fault is a single / multiple keys can not be the reason
Single keyboard can not be used, that will affect the user's daily use, letting users feel gesture. The Failure of the overall performance of using the normal keyboard, but the keyboard is a local one or more keys, there click unresponsive or intermittent failures. The cause of the problem, because the keyboard film conductive line inside a fracture caused by virtual access. Part of the hands-on ability of the player, you can use a multimeter to measure open circuit after the find, then use conductive paint or pencil repair. As for the average player, or directly replace the keyboard more peace of mind easy.
4, mobile phone leads to a keyboard can not be used

Poor quality of phone calls when the keyboard will cause interference
Users in the use of computers, may also find a very strange phenomenon keyboard can not be used. The symptoms manifested on the keyboard side of the phone to the phone, the keyboard does not use all the keys phenomenon of. The problem is mainly due to inadequate internal keyboard shielding design. Phone when the phone is turned on, the wireless transmitter power increases, will cause some electromagnetic radiation, shielding the internal keyboard design is bad, it will interfere with the normal use of the keyboard, for this keyboard, or as early as possible to replace the players, in order to avoid daily use caused trouble.
Third, the driver causes the keyboard can not be used
5, driver exception causes the keyboard can not be used

Drivers can cause damage by viruses keyboard failure
V above, are due to a hardware problem or a design flaw caused by the product itself can not use a keyboard, viruses and software reason, will result in the phenomenon of the keyboard can not be used. Users discovery keyboard failure. View the device in Device Manager, you will find a yellow exclamation mark appears on the keyboard device. Some computer experts can accordingly by removing the registry key, and then reload the device to fix. But for most ordinary users, the problem occurs, the most easy solution is to reinstall the system (because the keyboard can not be used after a problem).
6, laptop keyboard does not work properly
Of course, for laptop users, the most common keyboard failure is the most common phenomenon is that the letter keys on the keyboard is pressed, the playing out not correspond to the letters, but a bunch of numbers, a phenomenon that so many novice users headache . The reason, in fact, because between the user inadvertently open the keypad on the keyboard.

Printed on the right side of the laptop keyboard buttons with yellow numbers
Because of the limited size of the laptop, the keyboard layout are compact, no separate numeric keypad. When part of the user will experience high frequency input digital use. Computer manufacturers to address this phenomenon, using an ingenious solution, the design part of the button on the right side of the keyboard into a tilted numeric keypad, and then add one other key combination to achieve by FN button keypad open. Just find the laptop user on the keyboard printed with NumLock key, then press together with the FN button, you can reset the keyboard.

Laptop battery power measurement methods

Laptop battery is used, the less the more normal? To explain this, you have to talk about the structure of the battery itself. Before we understand the basic structure of the battery, notebook batteries and battery is composed of management chip. Batteries that store electricity "warehouse", power management chip is able to calculate and manage the charging and discharging process. The main element in the functioning of batteries is lithium, which is a dynamic element, in order to protect the security, can only exist as ions in the battery. Lithium batteries similar shape with ordinary batteries, laptop batteries, but do often occur in groups. We often see the "four core", "six-core" refers to the battery in the battery is the number of batteries.
Batteries and more, means that capacity is large, the number of high-capacity batteries battery is generally about eight. The reason comes to batteries group, because a group of batteries is the battery charge decrease the "culprit." Batteries batteries each group, its quality and discharge levels vary. After discharge, in order to maintain voltage stability, management chip detects that a worst batteries charging protection. Often the past, the entire battery power naturally will gradually decrease. This phenomenon can be used after the battery calibration function, this function can be balanced multi-cell battery burden "work."
It should be mentioned here have battery power measurement methods, common approach four kinds, but in general are integrated several methods used in one of the main methods for calculating manner calculated to achieve the remaining auxiliary power calculation and management.
Open circuit voltage measurement
This method is by measuring the battery voltage value in the stationary state to calculate the remaining capacity of the battery, but because the relationship between lithium ion battery voltage and remaining capacity of the still between the non-linear, and therefore the measured value of this method is not accurate the vast majority of cell phone batteries have adopted this method of calculation.
Coulomb calculation
This method is by measuring the battery charge and discharge current, the product of the current value and time value are calculated by integrating the battery after the charge into the charge and the release of electricity, Coulomb calculation method is a more accurate power calculation.
Impedance measurement
It obtain residual capacity value of the battery by measuring the internal resistance of the battery.
Comprehensive look-up table
By setting a related table, voltage, current, temperature and other parameters input, you can check to get the battery's remaining capacity.
But no matter which method, while charging management chip follow the "bucket principle" to the status of the worst batteries subject to protection. Therefore regular correction can protect the battery cells to some extent, to extend the overall life of the battery.

Hard to build software RAID speed

Software RAID, as the name suggests, is through software simulation way up RAID system requires no special hardware support, and without BIOS support. And the formation of hard RAID, you need to use RAID card or onboard RAID chip to achieve, only a few high-end gaming or desktop PC with this feature.
Because software RAID does not require specialized hardware and BIOS support, so almost all installed Windows XP or higher operating systems can be set up in the laptop system, because the operating system from Windows XP era, disk management tool provides a soft RAID function, and the formation process is very simple, does not involve too much for hardware changes. Also in the set up, the system on the hard drive capacity is also no special requirements, this is the same as RAID and hard. There is only a cost: a need for additional mechanical hard drive, such as a laptop hard drive is idle.
Formation of a simple risk-free
Software RAID can achieve RAID0, RAID1 and RAID5 disk mode, etc., and in the same system, we can use more than one hard disk partition, two hard drives of different partitions were formed into a RAID0 or RAID1 mode, which is hard RAID mode can not be achieved, since the entire hard drive hardware RAID must be fully integrated into the system in order to begin to form, especially in RAID0 mode, you must first complete the formation to begin installing the operating system. Of course, reflected in terms of stability, it is much stable than software RAID.
On Windows systems, RAID0 mode is called the striped pattern, it has the best performance; RAID 1 mirrored volumes were referred to as the model, with the best security. Of course, to speed, we sure it is set up RAID0, is striped. As for the formation of steps that can be simply summarized as three steps:
The first step: to install a hard disk in the drive position
Since the formation of soft RAID0 need to use at least two hard drives, so we can use the laptop's optical drive to expand, the method is very simple, to tear down the existing drive, with the optical drive bay hard disk conversion, the new installation of mechanical hard disk installation to drive bit. Need to remind everyone that the current hard disk drive bit 12.7mm and 9.5mm converter bracket has two thicknesses available, we need to purchase for their own laptop thickness optical drive bay hard disk conversion.
Step Two: The hard disk to a dynamic disk
As follows: Right-click on "My Computer → Properties → Disk Management" in Disk Management, right-click interface to convert the hard disk - the first is the original main hard drive, select "Convert to Dynamic Disk" option that appears to ignore "Unable to enter the operating system," the warning, the original hard transition from the basic model to the dynamic mode, if you have that you do not need to convert a dynamic disk mode. Using the same method to add an extra hard drive also convert incoming dynamic hard drive.
Here we may be worried about the system and data security. Actual situation is: we will be equipped with a hard disk Windows7 operating system after the conversion to a dynamic disk, partition, and data were intact after the restart can also enter Windows7 operating system again. But to be safe, we still recommend that you back up important data before proceeding.
In conclusion, if your system has been installed with an operating system, is able to carry out the formation of (repeat: the best backup data) without losing data are available, but the process is irreversible.
Also in the transformation process, we also found that some Windows7 operating system has been installed in the laptop hard drive can not be converted from a basic disk to a dynamic disk, right-click on the hard drive would not appear this option, then the only way is to reinstall the operating system, and the system comes with Windows partition tool partition after installing can be converted.
The third step: the formation of RAID0 mode
At this point in the disk management interface, right-click on the following a mechanical hard drive, select "New striped volume" command and select the other, a dynamic disk, select it and follow the instructions step by step operation can be. Need to remind everyone that, and set up the same way as hard RAID, striped set up after the success of capacity, the total capacity of the two partitions of two times the minimum capacity. The formation of such capacities are two partitions 931.41GB and 280.11GB, then the new partition size after the formation of soft RAID0 was generated 560.22GB.
Hard to build software RAID speed
The highest performance increase of 77%
From the test results, we will set up two hard drives become a "striped (RAID0)" mode, the hard disk read speed has been greatly improved. With the fastest 1TB mechanical hard, for example, after the formation of striped, hard AS SSD BenchMark random read speeds up to 172.86MB / s, relative to the previous speed 100MB / s or so, the performance improvement is obvious, but in the Fastcopy other tests and test projects, have been greatly speed growth, especially in the small 500MB file transfer tests, the striped 117MB / s transfer rate 77% higher than 1TB hard drive 69.27MB / s in growth.
Performance and hardware RAID close
To give you a more intuitive understanding of the performance difference between software RAID and hardware RAID, we have a laptop in a unified hardware and software platform, using laptop comes with hard RAID function was tested using the same software used in two RAID hard disk formation.
As can be seen from the test results table, and RAID0 hard compared to soft RAID0 did not show a distinct disadvantage, at least from the perspective of the prototype we tested the answer is true. In the four projects we tested, the soft RAID0 two projects are ahead of hard RAID0, especially Fastcopy test project multiple small files, RAID0 hard behind the relatively large magnitude of gall.
Editor: Idle hard to realize the value of a good choice
About Software RAID, this is not a new topic, before we tested on DIY platform by utilizing three disc set up soft RAID. But for the purposes of laptop platform but few people involved, because in the past there is little laptop will have a hard RAID functionality, so we can not evaluate the effect of soft RAID set up on the same platform. But by the above tests, the results of some presumably contrary to all expectations, soft RAID also received not less than hard RAID performance, so if we qualified, we can also try to verify this on many more platforms.

How laptop power?

Users want mobile office with a laptop, it is most worried about is the laptop's battery is not enough, what skills make laptop batteries last longer in Win7, change what settings win7 laptop to let it use up more power, the following to see how to set up Win7 for laptop battery last longer.
1, the energy consumption of free resources
When a computer starts, not always running at full load condition, so there will be a lot of idle time, idle time, power consumption has become an important power management technology. In win7, the idle power consumption is effectively improved after a certain period of time the hardware does not work it will enter a low-power state has to save battery power. Including CPU, hard drive, memory and network elements have adopted this technology. For example, a full power run power 35w of the CPU power consumption at idle is almost 0, only this one will be able to save a lot of power.
2, Bluetooth devices to improve power
When win7 detected Bluetooth devices in a low-power state, they will be temporarily closed, or "selective suspend."
3, increased processor power management
win7 incorporates the latest in power management technology, which enables Windows 7 to dynamically adjust CPU performance based on the current load conditions and performance requirements.
4, low-power audio
win7 will support Intel's low-power HD audio specification, which allows encoding *** into low power state. win7 also supports selective suspend technology to shut down idle equipment, such as microphones and cameras such USB devices.
5, through the trigger to start the service
System services are typically started at system boot time together, and then wait for the call resides in the background. In Windows 7, the service is only part of the system is triggered by some event will start, such as inserting a device or change IP. This can reduce the number of services in the long-running background processes.
6, adaptive display brightness adjustment
Microsoft said, usually without the operation, the display will automatically turn off in 10-15 minutes time. But there will be no more short-term operating conditions in actual use, in order to better energy efficiency, this technology will reduce the brightness of the display. In addition, it could use some sensing devices to adjust the brightness according to ambient brightness of the display.
7, network equipment to improve power
win7 compatibility for wireless network controller in low power mode has been strengthened, and only in the device supports low-power wireless AP mode is enabled only. Vista because it can not detect in advance whether to support low-power mode, it will lead to a sudden interruption of the wireless network connection. win7 will prevent this from happening, before entering a low power mode will first detect the wireless AP support this mode.
8, integrated timer
Currently processor by utilizing spare time gap processing instructions to save energy, but most free time saving techniques require a certain length in order to obtain energy savings. And this technology by making the Windows kernel originally terminated and focus more dispersed multiple timers at the same time, the processing is completed in a short time, thus increasing the idle time of the processor. In addition, when using the battery in the laptop case, win7 will reduce the frequency of non-critical activities daemon.
The above is win7 several important improvements in power management, compared to the previous system can save more energy. After the above through improved laptop battery life has been extended under certain Win7.

Pregnant women with a computer 12 major considerations

Computer disease, every day working women are the guard, not to mention the pregnancy? Pregnant women need to pay attention to what use a computer?
1, pregnant women have access to computers weekly time is not more than 20 hours
To prevent pelvic blood retention caused by prolonged sitting poor, so that a degree of relaxation; pay attention to the level of the computer and the sitting position with the seat, so that the healthy development of the fetus.
2, pay attention to rest, to prevent the tendon strain
Prolonged use of computers will lead to finger joints, wrist, arm muscles, shoulders, neck, back and other parts of soreness and pain, so pregnant mothers at work an hour later should rest for 10 minutes, or do work between the parade.
3, pay attention to eye health
Eyes and presentation, the distance between eyes and the screen should be maintained at 50 cm or more, the best use of light depending on the viewing angle of 20 degrees. Work, radiation protection should be applied in the face and hands and skin oils.
4, long engaged in computer operations pregnant women should eat plenty of fresh vegetables and fruits. While increasing vitamin A, B1, C, E intake.
To prevent corneal drying, eye dryness, decreased visual acuity, or even night blindness and other computer pregnant women should eat more foods rich in vitamin A, such as soy, fish, milk, walnuts, vegetables, cabbage, tomatoes, spinach and fresh fruit. Vitamin C can effectively inhibit oxidation. The main role of vitamin E are: lower cholesterol, clear body waste, prevent cataracts. Walnuts and peanuts are rich in vitamin E. Vitamin B1 can enhance nerve cell nutrition, relieve nervous tension.
5, the bubble point of green tea a day
Tea LPS, can improve the body's blood work can be. Body after injection of LPS, in a short time you can enhance the body's non-specific immunity. Tea can also radiation damage.
6, in order to avoid reflective screen or unclear, the computer should not be placed on the side or rear windows.
Ambient lighting should be soft, if there are windows behind the operator should draw the curtains to avoid direct exposure to light on a bright screen image reverse cause eye fatigue.
7, the computer room and often ventilation
In the indoor fan or air conditioning installation, reduce bromine than dibenzofurans impact on the body, the computer room near the dust density than a hundred times higher than the other space, which for a long time attached to the skin, can cause various types of skin diseases. Computer room to keep clean, the computer should be regularly cleaned.
8, most people blink less than 5 times per minute would dry eyes
A man working on a computer at the blink of an eye and only one-third the usual number of times, thus reducing the secretion of eye lubricants and enzyme. Should blink every hour to let the eye rest at least once.
9, the computer room light to fit
Not too bright or too dark to avoid direct exposure to light on the screen caused by interference of light. Studio ventilation to keep dry.
10. To use the filter on the computer screen
To reduce visual fatigue. Preferable to use high-quality glass or plastic filter.
11, to keep the skin clean
Computer screen surface there is a lot of static electricity, which can be transferred onto gather dust face and hands exposed skin, a long time, prone to rash, pigmentation, severe cases may even cause skin lesions and so on.
12, to adopt the correct typing posture
Correct typing posture on the health of the body parts of the body plays an important role, suggest that pregnant mothers typing a closer look at their posture is correct, if you have a long day sitting in front of the computer, then give some bad posture Your body has brought great harm.
You may wish to prepare for a long time working in front of the computer, choose the right equipment, seated posture, bring more comfort for your body, reduce the incidence of various Yin Ji. Love yourself a little more each day, it will make your body better, with more stamina to meet the challenges of work and better bear breeding mission. We passed summarize, summarize the following principles, I hope we can develop good habits!
1, the screen and keyboard should be directly in front of you, you should not let the neck and wrists that oblique state.
2, the top of the screen should be lower than the level of your eyes, and because one of the least distance from the screen of your arm.
3, to sit on the sit up straight, do not sit Bantang half. Do not let your body sitting posture angle errors.
4, should be kept in the front thigh is parallel arm posture.
5, hands, wrists, and elbows should be kept on the straight line care. No that is not the bend.
6, feet should be flat on the floor can be easily or pads.
7, the height of the seat should be adjusted to your elbows bent almost 90 degrees, and your fingers can naturally shelf just above the keyboard.
8, if the chair itself is not designed to protect the back curve, you'll buy a protective back pad. Remember to keep the waist to the back of the curve. Office staff are now sitting on a chair for too long, regarded as a lifestyle diseases. If you sit crooked it worse.

How to prevent computer radiation damage to the skin

Drinking green tea can prevent computer radiation
Computer radiation not only harmful to human health, but also affects the quality and efficiency of the work. For life is stressful and busy people who resist the computer radiation easiest way is to drink 2-3 cups of green tea in the morning, eat an orange. Tea is rich in vitamin A former, it is absorbed by the body, can be quickly converted into vitamin A. Not only synthetic vitamin A rhodopsin, but also make the eyes in the dark light, see things more clearly, therefore, green tea can not only eliminate the computer radiation hazards, but also to protect and enhance vision. If you are not used to drink green tea, chrysanthemum tea can also play against the computer radiation and regulate bodily functions.
Help you reduce computer radiation
Technical staff, said the computer radiation is inevitable, but it can be reduced. First, you should buy as new computers, generally do not use old computers, old computers radiation are generally more powerful, at a distance, the same conditions of similar models, typically 1-2 times the new computer. Operate a computer screen when the best in computer security a special color filter panels to reduce the radiation hazards, indoor loitering metal objects should not be placed in order to avoid the re-emission of electromagnetic waves. When using the computer to adjust the brightness of the screen, in general, the bigger the screen brightness, electromagnetic radiation is stronger, the smaller the contrary. However, it can not be stressed too dark, so the brightness is too small to affect results, and could easily lead to eye fatigue. Also keep an appropriate distance from the screen. Closer from the screen, the greater the body suffered electromagnetic radiation, so good is half a meter away from the screen.
Computer radiation damage the skin, used computers should wash
Computer work is increasingly becoming essential supplies, dermatologists has reminded, when the daily operation of the computer, be sure to wash after using the computer. Physical and computer screens should be kept at least 70 cm distance as possible.
The amount of radiation produced by the computer screen, although small, but over time will continue after damage the skin, prone to facial pigmentation, slack skin around the eyes, crow's feet, eye bags and dark circles. City Dermatology Hospital experts advise frequent computer users, especially women, in the front of the machine is best to apply some protective equipment, such as such as Cream or foundation. At the same time, it is best to use the computer screen protection. After using the computer, it is best to wash your face regularly. Because for a long time in front of the screen, the skin is also prone to excessive secretion of oil, dust accumulation and so on. Before going to sleep, the computer runs more need for timely clean skin.
The maximum radiation damage in computer keyboard
Do you often feel heavy head or memory loss it?
Tummy sleep time to remember to shut down the computer, not just turn off the screen only. Because only turn off the screen can not prevent radiation, and we are tummy sleeping, head directly into the computer, the day had Alzheimer's disease or brain tumors too late.
Computer used to sit at the table for you, whether it sit for several hours and incorrect posture, always feel inexplicable neck and shoulder pain, and even the motivation to work? You may now be a quiz, you looked to the left direction, and then head down slowly bend 45 degrees, action to do here, your neck and neck and shoulder pain is not normal to feel? Given the above symptoms, you have to be careful, because you probably got the modern computer diseases of civilization - "thoracic outlet syndrome."
Do you know the amount of radiation a computer is?
A keyboard 1000V / m
2, mouse 450V / m
3, the screen 218V / m
4, host 170V / m.
Therefore, when you use your computer and enjoy the fun of the Internet, please be careful

Computer radiation and women's health
Today, a large number of professional women to enter management, business, finance, telecommunications, services and other agencies dealing with the computer, according to the information, computer operators are mostly women, half of them for women of childbearing age. As well as television, video, audio, computers, copiers, refrigerators, vacuum cleaners, microwave ovens, radios, mobile phones, cordless phones, power transmission lines, etc. All electrical appliances generate electromagnetic radiation, and electromagnetic radiation has on human health has far-reaching Jeopardy! A full range of computer has changed the lives of women, but also a full range of influence female fertility, beauty, health aspects.
1, pregnant women should pay attention to electromagnetic radiation
Last year, the World Health Organization in the latest amendments to the computer screen and work-related health problems noted in some of the computer screen work environment factors that may affect pregnancy outcome, recent studies have shown that pregnant women more than 20 hours per week using computers, the abortion rate increased 80 percent, while also increasing the birth rate deformed children. Sweden last year to become the strength of more than 0.2 micro tesla harmful low frequency electromagnetic fields of the world's first officially recognized.
2, the effects of electromagnetic radiation on beauty
During the interview, many of the recent close contact with VDT staff complained of facial brown spots increase. Professor Jin Xi introduction of foreign materials VDT operator repeatedly referred to the skin may appear red blood rash, was a line string-like, sometimes manifested as erythema or eczema symptoms similar to face-based, women and more. 1998 International Journal of Epidemiology reported: electromagnetic radiation cause female endocrine disorders are the main breeding ground for a large number of melasma.
3, electromagnetic radiation leads to psychological pressure and communicative incompetence
Meanwhile, according to an authoritative new study funded by IBM and other large companies announced several staff computer networks tend to become more withdrawn, irritable, difficult to close and communicative incompetence. Professor Huang also pointed out that miscarriage, brown spots, etc. are also closely related to psychological factors.
Somewhat affected computer radiation on the human body, but there is no standard can be based on, but note the following points can effectively reduce the radiation, some errors can avoid wasting money.
1, Shibao Ping is simply psychological comfort, and now have a CRT monitor radiation anti-static coating, you can hand in front touch display screen, no crackling static, but to no radiation is recommended to choose the LCD screen.
2, the host chooses the better brands such as Lenovo, with only relatively thick chassis, the interface has a radiation seal seams tight, placed under the table.
3, ground to rest, is a good idea to wash your face.
4, Cream and sunscreen absolutely no role, Cream is to prevent dust substances, sunscreen to prevent UV, did not prevent the radiation component, without having to spend time and money, but in the interior coating or some sunscreen to prevent UV refraction, Sunscreen can only play the role.
5, and now more and more electronic devices society, do not live so scared, even without a computer watch TV Yeah, there are many kinds of radiation in the air, do not worry too much.

Computer maintenance precautions and common fault analysis

With the rapid development of computer hardware and software, along with the gradual popularization of computer society, more and more people begin to repair the computer yourself, but with my years of experience in electronics repair work, the use of computer maintenance is more important than the maintenance, the following I will maintain, repair computers should pay attention to some of the issues we talk about the same, I hope we can bring some help.
The working life of a computer is limited, if maintained well, it will extend the life and work has been in relatively good condition, you can try to play its role; on the contrary, one or maintained and unmaintained bad machine, first of all it will not be in good working condition, important data may be lost for no reason, the operating system may be wrong every few days, scheduled work can not be completed, and more importantly, will greatly reduce the computer of life, so do the daily maintenance of the computer is very necessary.
We will routine maintenance of the computer hardware maintenance and software maintenance is divided into two areas, the following specifically to explain these two aspects of computer maintenance.
Public want good work must first sharpen his tools, so conveniently set of maintenance tools are required. Computer maintenance need not be very sophisticated tools, general dust maintenance only need to prepare a Phillips screwdriver, flat screwdriver, paint brush (or oil paints, ordinary brush easy removal, should not be used) can, if you want to clean the floppy drive, CD-ROM inside, but also need to prepare lens wipes, hair dryer, ethanol (AR), cotton balls, watch screwdriver (a), tweezers, a blower (Paper Tiger), paper clips, watches oil (or sewing machine oil), butter. If need further repairs, and then prepare a needle-nose pliers, a test pencil and a multimeter.
A, hard to maintain a microcomputer
Maintenance refers to the so-called hard to maintain in terms of computer hardware, which includes considerations such as computer use and a variety of devices for routine maintenance and working.
1, computer work environment
For a computer to work in the normal state and extend the service life, must make it in a suitable working environment, should meet the following conditions:
1.1 Temperature Conditions
General computer should work at 20-25 ℃ environment, although it is now a computer cooling performance is very good, but the heat generated by the high temperature is still scattered not make the computer work out, ranging from shortening the life of the machine, while burning computer chip or other accessories, computer hardware now developing very quickly, very fast replacement, cooling the computer has become a problem can not be ignored; the temperature is too low will produce poor contact between the various parts of the computer problems, causing the computer does not work, conditional, the best placement of the computer room air conditioner in place to ensure the normal operation of the computer required ambient temperature.
1.2 humidity conditions
Humidity is not too high, the computer in working condition should be kept well ventilated, otherwise the circuit board inside your computer is susceptible to corrosion, so the board of premature aging.
1.3 good dust
Due to the various components of a very sophisticated computer if the computer work in a dusty environment more, it is possible to plug a computer interfaces, so the computer does not work, so do not place the computer in a high dust environment, if they really needs to be installed, should be prepared to dust the work; in addition, the best month to clean up the dust inside the computer case, good job cleaning the machine, in order to ensure the normal operation of the computer.
Dust Note:
(1) In the first host before attempting to clean power, unplug the power cord host;
(2) Try not to turn on the power, clean the inside, inside a high voltage!
(3) Do not attempt to open the display, a high voltage inside!
(4) The first look at the weather before cleaning, it is best not to vote in the rain and cloudy when clean air humidity, that would cause oxidation cable plug.;
5, during the cleaning process is best to use a soft brush, if the bristles are excellent devices will increase the chance of damage
1.4 Power Requirements
Voltage instability is likely to cause damage to the computer circuits and devices, due to the presence of the mains supply peaks and troughs, frequent fluctuations in the voltage environment, preferably with a regulator to ensure the required stability of the normal work of the computer power, although the country to strengthen the power supply in rural areas, to improve the power lines in rural areas, but relatively far away from the cities and towns in remote rural areas is still quite unstable voltage, using a computer in this environment, must be equipped with regulators. In addition, if a sudden power outage, it may cause loss of data inside the computer, and can also cause serious computer system will not boot and other failures, so, in order for the computer to power protection, should be equipped with a small home UPS, guarantee the normal use of the computer.
1.5 precautions against static work
Static electricity may cause damage to the computer chip, in order to prevent electrostatic damage to the computer before you open the computer should touch the heating pipes or water pipes and other objects can be discharged, will discharge static electricity before touching their own computer accessories; other Keep the computer in the chassis grounding wire, can play a very good anti-static effect. Do not wear clothes fiber cloth for maintenance work, do not have carpet in place for maintenance, repair and sprinkle a little water the best place to increase the humidity, this can effectively reduce the generation of static electricity in order to avoid electrostatic breakdown element of human error occurred . Now comes the static, I'll tell you how to static electricity, the method is very simple, as long as the computer's chassis ground on the line, another cabinet charged is very common problems, especially in the old house, because most do not have these old residential land lines are three-phase four-wire system (that is, three fire a zero), since there is an indirect capacitive many ATX power supply housing and the zero line, so if you reverse the zero line and the line of fire, then charged up on the chassis, However, the voltage (current) does not cause personal injury or death, then how to determine whether reverse it? Quite simply, if you use the back of the hand to touch the metal parts of the shell without being charged feeling (slightly electrically) to prove that there is no reversal, or electric pen test it, but some will let electric pen casing look bright, but soon off, then you can conclude that not reversed, if it proves indeed reversed, then you will plug inserted Haojiu Hang tune all; there's a friend when it comes to how the ground should be connected, some newspapers the article also mentioned the grounding method, but as the building users can not do in any case, I will tell you the following two ways:
(1) at zero, FireWire are not reversed the premise to the hardware store to buy a 10mm bolt and hit the wall, and then the outlet end of the hollow of the ground with a more than 1mm2 received enameled copper bolt on (can then take a nut on the bolt, and then placed on the line in the middle of two nuts and nut tight), conditional comrades tin can on both ends of the ground to oxidation;
(2) at zero, FireWire are not reversed the premise of the housing directly to the zero line, such as insurance, then you can not be afraid of the enclosure through a 0.1μF / 400V capacitor connected to the zero line of Promise, I strongly Recommended use capacitive grounding method, because there may be in future line transformation happens, if construction workers mistakenly zero FireWire reverse if you will not be in any danger (himself encountered zero, FireWire is reversed things ), this method is applicable to all the electrical lead into the zero line and the electric pen does not light users.
Failure patients: an old friend 486 machines, symptoms start a black screen and the same type of machine to swap hard drives, the fault plane normal start of replacement black, it is hard to judge bad. I approach: one end of the wire with a computer case, a termination pipe, and later re-plug the memory, and then the CMOS discharge, restart normally.
1.6 to prevent vibration and noise
Vibration and noise can cause damage to computer components (such as the hard drive is damaged or missing data, etc.), so the computer can not work in a lot of vibration and noise environment, if they really need to be placed in a large computer vibration and noise environments should consider installing shock and soundproofing.
2, the computer's place
The host computer should be placed smooth, retain the necessary work space set aside to place disks, CDs and other commonly used spare parts in order to facilitate the work place. To adjust the height of the good of the display, the display position should be maintained substantially parallel to the top line of sight, too high or too low will cause operator fatigue. In the computer when not covered with dust cover is best to prevent the invasion of dust on the computer, but do not forget that, in the case of normal use of the computer, be sure to win the dust cover to ensure that the computer can be a good heat dissipation.
In addition, if the computer is not a long time, the best month should energize a secondary, high or low temperatures, humidity is too large, easily deformed board computer to produce poor contact, such as failure to make computer does not work. Especially in the rainy season in the south should pay more attention to ensure that the computer is powered least once a month, every power-on time should be less than two hours, so as not to deform wet weather makes the board computer is not working properly.
The following specific about the various components of a computer routine maintenance.
3, routine maintenance of computer motherboard
The important role of the computer's motherboard in the computer can not be ignored, good or bad motherboard performance to some extent determines the performance of your computer, there are a lot of computer hardware failures are due to the computer's motherboard and other components damaged by bad or motherboard produced good motherboard routine maintenance, one can extend the life of your computer, the more important is to ensure the normal operation of the computer, to complete their daily work. Computer motherboard main routine maintenance should do is dust and moisture, CPU, memory, display card and other important components are plugged into the motherboard, if excessive dust, it is possible to make between the motherboard and the components poor contact, resulting in this kind of an unknown fault, to your work and play great trouble; if the environment is too wet, then the board is easily deformed and produce poor contact failure, affect your normal use. In addition, when assembling a computer motherboard fixed not to overtighten the screws, each screw should use the same intensity, if overtighten words are likely to enable the board to produce deformation. Special attention should be IDE interface, AGP, PCI and memory, and so the human damage the motherboard socket on the motherboard.
4, the routine maintenance of the CPU
To extend the life of the CPU, ensure that your computer is stable to complete daily work, we must first ensure that the CPU is operating at normal frequency. To improve computer performance by overclocking is not desirable, in your experience the so-called high-performance, you also take your life at stake in the CPU, unless there are fanatical pursuit of overclocking, wanted drained per CPU little energy Diyer, when the computer is working properly, try to make the CPU is operating at the rated frequency. On the other hand, as a relatively large heat computer parts, CPU cooling issues can not be ignored, if the CPU does not heat well, it may cause the system not working properly, no reason to restart the machine, crashes and other failures give you choose a good CPU cooler is essential. In addition, if the machine has been working properly, then do not move CPU, CPU to clean up after cleaning the chassis, the installation must be careful to place, so as not to cause the machine can not boot failure.
5, routine maintenance of memory
For memory, it needs attention is the time to upgrade the memory, try to choose the brand before, like the FSB to memory and memory to match the previous use of the system is not functioning properly to avoid failure. Note that the operating voltage of the memory are the same. General adapter cards and memory of the finger no gold, just a layer of copper foil, a long time oxidation occurs. Eraser to erase the finger surface dust, oil or oxide layer. Type of thing must not use sandpaper to clean finger, otherwise it will damage very thin coating.
6, the graphics and sound routine maintenance
Computer graphics is a big heat, and now have a separate graphics card with a cooling fan, usually pay attention to what the graphics card fan is functioning properly, there is an obvious noise or operation is not flexible, turn stopped while other phenomena, such as found to have these problems, we must promptly replace the video card cooling fan to extend the life of the graphics card. For sound, it must be noted that, in the plug microphone and speakers, be sure to turn off the power at the situation, do not carry out such operations in the live environment, in order to avoid damage to other parts.
7. Notes on the hard disk during routine maintenance and use
In order to make the drive to work better when using the above points should be noted:
7.1 hard disk being read, write operation can not be a sudden power failure
So great is the hard drive speed, usually 5400 r / min or 7200 r / min, the hard disk read and write operations, the hard disk rotating at high speed, should a sudden power failure, may cause severe friction between the head and the disc damage to the hard disk. Shutdown when we must pay attention to the hard disk light on the front panel of the chassis is still flashing, if the hard disk light flashes more than shows hard disk read and write operation has not been completed at this time should immediately turn off the power, and only when the hard disk light stops blinking hard to complete the reading before the shutdown after a write operation.
7.2 to keep the sanitation
When you use the computer in humid, dust and dust environment seriously overweight, have more contaminants adsorbed on the internal surface of the printed circuit board and the spindle motor, affecting the normal working hard when you want to install a hard disk with printing down the back of the circuit board, to reduce exposure to dust and the circuit board; in addition, a humid environment will make electronic devices such as unstable insulation resistance, in hard to read, easy to produce data loss failure writes. Therefore, we must keep the environment clean and healthy, reduce the degree of moisture in the air and dust content.
7.3 Do not open the hard cover their own
If the hard disk physical failure, do not open the hard cover themselves, because if dust in the air into the hard disk, in read heads, will scratch the disc or head during a write operation, if you do need to open the hard cover for repair, it must to be sent to the manufacturer for repair professional, do not open their own hard cover.
7.4 earthquake measures do hard
Hard disk is a precision device, while working in the disc surface floating head height of only a few microns, when the hard disk in reading, writing and state, once a large shock occurs, it could result in the head and the disk crash, leading to a hard disk damage. Therefore, when the computer is running, it is best not to move, in addition, the hard disk when you move or transport the best protection with the foam or sponge packaged to minimize vibration.
7.5 Ambient temperature control
Hard work will produce some heat, use appropriate temperature to 20-25 ℃, the temperature is too high will cause the hard drive circuit component failure, magnetic media will be due to thermal expansion effects and affect the accuracy of records; if the temperature is too low, the air moisture will condense on the integrated circuit components and cause a short circuit. Try not to make the hard close as speakers, speakers, motors, televisions, mobile phones and other magnetic field, to avoid interference.
7.6 Take the hard right
The hard disk in your hand, do not bump caused by physical damage, then one needs to pay attention is to prevent electrostatic damage to the hard disk. Especially in dry weather can easily produce static, if not carefully touch the hard disk on the back of the circuit board, static electricity is likely to hurt the hard disk of electronic components, resulting in hard drive is not operating properly. Correct hard way by hand by grasping the sides should be hard, and avoid direct contact with the back of its board.
8, drive routine maintenance
Computer's CD-ROM drive is easy to go wrong, the failure rate is second only to the mouse, if maintained well, the drive can be used normally for many years, the use of improper or insufficient maintenance, and some can only use about half a year, the daily drive to note the following:
8.1 keep the drive clean
Each time you use the CD-ROM, CD-ROM are inevitably some dust into dust if the laser emission head falls, it will cause the drive to read the data difficult to read the disk affect the quality and longevity of the laser head, will also affect the internal drive various mechanical components precision, so interior must be kept clean to reduce dust. Clean the inside of the mechanical drive components generally available swab, the laser head can not use alcohol or other cleaning agents to wipe clean if necessary, you can use the balloon to blow off the dust and the alignment of the laser head must be careful when operating, there is little attention possible damage to the laser head.
8.2 to make use of genuine CD
Although some pirated CDs (especially VCD discs) can play correctly, but because of the poor quality of the disc polishing Road deviation, frequent error correction when CD-ROM drive, so the laser head control components easy to aging, will accelerate the drive internal mechanical wear If prolonged use of pirated discs, CD-ROM error correction capability not only greatly reduced, affecting normal use, but it also reduces the life of the drive.
8.3 try to use a virtual drive
We use computers for entertainment listen to CD music, watch VCD, and playing games, will inevitably result in the drive wear, after several hours of continuous playback VCD, CD-ROM greatly increased fatigue, continues to seriously affect the life of the drive, you can use virtual The drive CD, VCD and computer games into virtual hard disk, it will not only speed up the access speed, but also can extend the life of the drive.
8.4 to develop the habit of proper use of the optical drive
When we use the optical drive has many bad habits, such as hand direct closed doors, in the high-speed rotating disc forcibly eject the disc so that the doors, turn off or restart the computer does not remove the disc are all bad habits, direct will affect the life of the drive. CD to bring it up when not in use, as long as the computer is on, even without the disc, the drive is also to work with.
9, preservation and maintenance of the disc
CD store large amount of information, save for a long time, but the disc out if improperly stored easily damaged. CD-ROM discs to be stored in a dedicated box to avoid dust or dirt contamination, avoid scratch hard objects. Best not to pack a layer of plastic on the outside disc, because after a long plastic aging, and the disc may stick together, it is possible to peel off the protective layer and the data layer in plastic bags when opened, causing damage to the disc. Note save in front of the disc must also pay attention to save the back of the disc, if the back of the disc is scratched or off, it will cause light leaks, not reflections of the laser head laser emission resulting CD is not working, or even damage the disc . Use your hands do not touch the front of the disc when the disc, in order to avoid sticky hands sweat and dirt on the disc, causing some difficulties to read the disk.
Repair disc method:
The usual approach is to smear toothpaste and water data side of the disc, then use your finger clockwise direction repeatedly toothpaste evenly in the data side of the disc, through this approach polished scratches on the disc. Through the above method can solve most can not read CD-ROM, CD-ROM, but there are some irregularities with the above solution is not obvious, according to the following solutions:
Tools: a steam iron (iron have not tried the other), a thin cloth, a glass, a little water.
Steps:
A. First, will need to be repaired with a thin cloth wrapped disc, one side coated with it, then sprinkle with a cloth moistened with water, attention must be attached to the cloth on the disc can not have wrinkles.
B. then wrapped disc in a flat surface, you can find if you can not find the piece of glass, the glass is relatively fairly flat. Then the iron is heated to a certain temperature, with iron ironing repeated several times on the disc, wait to dry after ironing finished the repair work is completed.
10, the display routine maintenance
Displays such as improper use, not only the performance of rapid decline, and life will be greatly shortened, even with two or three years will be scrapped, so be sure to pay attention to the daily maintenance of the display.
10.1 Do not regularly monitor switch
Do not be too frequent switching the display, the best twelve minutes interval between on and off, on, off fast, easy to monitor internal instantly generate high voltage, so that the current is too large and will burn tube. If there are no monitors twelve hours, it is best to turn off the monitor for the home PC, it is recommended that at night when not in the package of equipment are turned off.
10.2 Dust work to do
High pressure inside the monitor up to 10KV-30KV, such a high voltage can easily attract dust in the air, the control circuit board adsorption much dust, it will affect the electronic components of heat dissipation, so that the temperature rise components burn components. Dust is also likely to absorb moisture from the air, the corrosion inside the monitor circuit, causing some inexplicable failures. The best time to buy a dedicated monitor dust cover after each use should be covered with a dust cover, remove the dust on the monitor screen, remember to turn off the power to the monitor, the monitor should unplug the power cord and signal cables, wipe with a soft cloth outward from the center of the screen, if dirt is difficult to remove, use a small amount of cotton wool dipped limit water carefully wipe, do not wipe with a chemical solution of alcohol and the like, in addition, long-term use of the monitor cabinet within will accumulate a lot of dust, will accelerate the aging of the display is not clear, you can remove dust and dirt with a brush on the monitor cabinet, use a dry cloth, do not try to wipe a damp cloth dampened with water. Be careful not to damage the circuit elements.
10.3 moisture
A long time without electricity monitor to regularly work for some time, so that the heat generated when the monitor is working to expel moisture inside the machine, because when the indoor humidity ≤30%, will monitor the mechanical friction generated static part, the internal components are electrostatically increases the possibility of damage, affecting the normal operation of the display; humidity exceeds 80%, it will produce condensation inside the monitor, internal power transformers and other coils are also easy to produce leakage after wet, mold may even break the connection.
10.4 Anti-magnetic interference
Electromagnetic interference would occur should not have circuit voltage and current, do not put strong magnetic material (such as a radio, etc.) placed the computer room, multimedia speakers must use a good anti-magnetic effect and should be kept away from the monitor.
CRT as a major source of the display, when working in high ambient temperature will accelerate the aging of components, and even some Weld joints may also be caused due to the solder to melt off the display unstable trunk. Should give the display a well-ventilated environment, to ensure that there is enough space for heat dissipation.
Anti-glare 10.5
Reflective screen glare would cause screen obscured, at work in the face of the display extremely easy to damage the eyes, but also accelerate the aging CRT phosphors reduce the luminous efficiency, shorten the life of the display. Therefore, do not place the monitor in place strong sunlight, the light must pass through the summer place to hang a dark cloth to mitigate its light intensity.
11, routine maintenance of the keyboard
11.1 kept clean
Excessive dust difficult circuit will work, sometimes resulting in misuse, impurities fall into the gap in the keys will be stuck keys, and even cause a short circuit. When we clean the keyboard, use a soft, clean, damp cloth to wipe the stain cotton swab to clean the gap between the keys, do not use alcohol, medical sterilization, in order to avoid adverse effects on plastic parts. When cleaning the keyboard must be in the off state, damp cloth should not be too wet, so the keyboard short circuit inside the water.
11.2 does not spill liquid onto the keyboard
Once the liquid spilled on the keyboard will cause poor contact, causing a short circuit fault circuit corrosion, damage to the keyboard.
11.3 Key to pay attention to the intensity

When the key must pay attention to moderate intensity, action should be gentle, strong percussion will reduce the life of the keyboard, especially when playing the game when the keys should be careful not to hard keys, so as not to damage the keycaps.
11.4 Do not hot swap
When replacing the keyboard not hot swap, hot plug is a great harm, ranging from damage to the keyboard, while there may be damage to other parts of the computer, undue loss.
Keyboard maintenance methods:
Injection: ordinary syringe to extract ethanol, misalignment keys seams injection, and continue to enhance the cleaning effect buttons. This method is simple and practical, on the periphery of the distribution of keys in the keyboard is especially useful.
Shaping method: using suction tin solder failure three feet keys open, remove the Cap, rod, shrapnel and a return spring, pull out the micro switch. You can find shrapnel had become depressed or flat, with a fine needle to pry formation
Convex, with a small screwdriver to gently struck the internal switch to the appropriate location. And finally by reverse order of removal can be installed.
Immersion method: This method is the key to open the fault, you can see the moving contact two small metal pieces constituted tweezers cotton on a small alcohol wipe contacts repeatedly until the exposed metal and bright, and finally re-installed
12, routine maintenance of the mouse
In all computer accessories, mouse most prone to failure. Optical mouse and mouse into mechanical mouse
12.1 Avoid throw touch mouse and a strong pull on the wires.
12.2 Do not click the mouse when excessive force, so as not to damage the elastic switch.
12.3 preferably with a special mouse pad, it will greatly reduce the chance of dirt into the mouse via a rubber ball, and increase the friction between the rubber ball and the mouse pad, if the optical mouse, then, also
A damping effect, holding the photodetector element.
12.4 When using the optical mouse, to keep it in a clean-plate photographic better state, to avoid the dirt attached to the LED and phototransistor, blocking the light reception.
13, daily maintenance of digital cameras
13.1 pre-use check
Before use to check whether there is dust on the lens, even if there is little dust are likely to eventually lead to a dark area, you should use special lens paper to gently wipe the dust. In addition, check the battery there is no safe, the memory card is ready, everything is no problem and then boot.
13.2 correct operation of the camera
During the shoot should be strictly in accordance with the instructions on operating instructions, if you save the photo, do not open or remove the memory card, so easily lead to memory card becomes corrupted, it is best not to use the camera's LCD screen back to the viewfinder, so you can try to save the battery. In using the process to gently, especially the camera lens, LCD monitor, etc. but also to protect sensitive components.
Keep after 13.3 with
Camera when not remove the battery in the camera bag, dry and ventilated place.
13.4 frequently clean the camera
Body brush to remove dust can also be used to wipe glasses cloth or flannel; dust on the lens you can use a large rubber ball (leather consideration) to blow off, wipe the skin do not consider blowing dirt with lens paper and perspiration, etc.
14, daily maintenance of the scanner
14.1 The scanner should be placed on a flat, vibration smaller place, there will be no extra work load so that when the stepper motor, you can guarantee to achieve the desired vertical resolution.
14.2 keeping the scanner glass clean, it is related to the scanner accuracy and recognition rate, to now when there is dust on the glass, it should be cleared up.
14.3 To the scanned image placed in the center of the starting line, so you can minimize the causes distortion due to the optical lens.
14.4 should not use more than the optical resolution of the scanner to scan accuracy, because doing so will not only improve the output effect is not obvious, but also consume a lot of computer resources.
14.5 Save to choose JPG format image, the compression ratio is 75% -85% of the original image size is too small will seriously lose information image, distortion.
14.6 anti-high temperature, dust, moisture, anti-shock, anti-tilt.
 Second, the maintenance of the soft microcomputer
1, make a backup system
When we use a computer, sometimes it will inevitably encounter this kind of failure, some failure is easy to solve, but can cause some serious damage to the operating system malfunction, so that the computer does not start properly. Then more trouble, to re-install the operating system, if you're lucky, the choice of covering the installation can repair damaged files, the operating system can operate normally, and if not covered by the operating system is installed properly, it is necessary to install an operating That system is formatted disk and reinstall the operating system, installed after also install drivers for various hardware and common software applications to be able to wait for the computer to restore normal use, the time has passed more than one hour, if Maintenance is before the old machine, not very good performance of the machine, then will waste more time. If we do a system backup, once the machine fails, as long as the backup to restore what to do on it.
We now commonly used system backup software is Ghost, Ghost make a backup for future use, even if you are a computer beginner, but also afraid of a system crash, as long as the machines are faulty, while he could not handle, then use Ghost to restore a system problems is a good idea. But the premise is to do well in advance of the system partition image file, the other to use in DOS, it is difficult for the novice, if misuse occurs, it may cause the whole partition data is destroyed, and Ghost disk image files take space is relatively large.
Of course, we can also use the system restore methods to achieve, System Restore is a feature of the times, there's WINDOWS ME to XP era, this feature has been enhanced, in addition to the System Restore function, but also can monitor the system and some applications change the program, and automatically create a restore point, this point in time restore point on behalf of the state, due to improper operation of the system if there is a problem, you can restore the system to normal state by past restore points created when the system is operating normally, and does not lead to the loss of existing data files, because it detects only the selected core set of system files and application files, does not detect changes in personal data files.
2, make a backup of important data
We hope that their machines do not have any problem at the time of use, but in practical applications, there is always this kind of fault to haunt us, so that we can very successfully complete their work, if unfortunate encounter a computer virus , worked hard to save important data loss, it will cause irreparable damage. Therefore, it is important to back up data must be good, able to do so, you can use a little hard to specifically store important data and documents, and now very fast computer replacement, upgrade the remaining small hard drive can be used to use . Even without the extra hard drive to use, but also with a floppy disk or other storage device to make a backup of important data and documents.
3. Install anti-virus software
Computer viruses that can lurk in some way in the computer storage medium (or program) where, when it reaches a certain condition is activated computer resources have damaging effects on a group program or set of instructions. A computer virus is a program, a piece of executable code. Like biological viruses, computer viruses have the unique ability to replicate. Computer viruses can spread quickly, and often difficult to eradicate. They can attach themselves on various types of files. When the file is copied or transferred from one user to another, they spread with the accompanying documents. In addition to replication capabilities, some computer viruses and some other common characteristics: a contaminated program can transfer the virus carrier. When you see the viral vectors seem merely in the text and image, they may have destroyed the file, and then format your hard drive or cause other types of disasters. If the virus does not parasitic contamination in a program, it is still occupied by the storage space for your trouble, and reduce the overall performance of your computer.
Virus types varied, the virus code vary widely, but the new virus production technology continue to emerge, so we can detect for known viruses, killing, and for the ability of the new virus did not know the future, even though they have a new virus Some common virus, but it uses technology will be more complex and unpredictable.
Therefore, in order to ensure the stability of computer systems and critical data is not lost due to erosion of the virus, we must install anti-virus software on your love machine. Several domestic anti-virus software can achieve the purpose of anti-virus, and the price is not too high, it is recommended that you buy genuine software, so you can update the virus database over a network, to maximize the protection of our computer.
4, install a network firewall software
In recent years, increasing cyber crime, the birth of a large number of hacking sites, prompting people to think about the security issues of the network. A variety of network security tools also followed hot on the market fired. Which was undoubtedly the most notable network security tools in the earliest maturity, is the first product of the network firewall product. The so-called "firewall" refers to an internal network and the public access network (eg Internet) separate ways, it is actually an isolation technology. A firewall is a network communication access in both the implementation of control scale, it allows you to "agree" to enter your network and data, while you "disagree" shut out people and data to maximize prevent network hackers to access your network and prevent them from change, copy, destroy your important information. Firewall for network security protection played a certain role, in order to take preventive measures, to install the network firewall software is one way to protect the machine works well.
5, regular defragging
Disk fragmentation is because the file is saved to various places throughout the dispersion disks, rather than continuously formed in the disk to save the contiguous cluster. Virtual memory manager frequent disk read and write, IE settings when browsing the web to generate temporary files and temporary files is the main reason it produces, file fragmentation usually does not cause damage to the system, but if too much debris, When reading the file system back and forth looking for, it will cause system performance degradation, leading to the loss of stored files, serious but also shorten the life of the hard drive. Therefore, the computer disk fragmentation can not be ignored, to regularly organize disk fragmentation, to ensure the normal and stable manner, we can use the system comes with the "Disk Defragmenter" to defragment the hard disk, but this program up and running very slow, here to recommend a good defragging software is "Diskeeper Professional", this software is a shareware version of its v8.0.459 size is only 1.8M, suitable for Win98 / Me / NT / 2000 / XP and other operating platforms, defragmenting when fast.
6, clean-up "parasites" Software
Such software is often "parasitic" In other normal software, or secretly installed on your system when you visit the Web site, endangering its system can not be ignored, one such software are background has been running, it will consume a lot of system resources and affect stability of the system, and also to overcome the valuable network resources, on the other hand may also steal your personal information. Main "parasites" software, there are three, one adware (Adware), many of the shareware is to get income in this way, but the software writers did not tell you that there is the presence of these adware, when you When using these shareware, adware also unwittingly installed came; the second is Spyware, that is spyware, it is possible that your system will send confidential hackers, causing your machine hacked or damage ; Yet another is the dialing procedure, which is the most dangerous type of proceeding, it can be put back into your dial international calls, resulting in the high cost of telephone, so you virtually suffered heavy losses. We can use the "Ad-Aware" to clean up the "parasites" software, this software is a free software that size is only 1654K, suitable for Win9X / 2000 / XP operating systems.
7, clean up junk files
Windows will run hoard a lot of junk files, and can not be automatically cleared for these junk files Windows, it only takes up a lot of disk space, but also slow down the system, so that the speed of the system slows down, so these junk files must be removed. There are two types of junk files, temporary files is a major presence in the Windows Temp directory, you will find that as you use the machine time to grow, increasing the use of the software, your Windows operating system will become huge the main thing is the existence of these junk files. Temp directory for temporary files, and just go to this directory can be deleted manually; then there is a temporary file that is when the Internet IE, we can use the following methods to manually delete, open the IE browser, select tool " Internet Options "This one, then select" IE temporary files "option, select" Delete Files "," Delete all offline content "and finally choose OK on the other, in the" History "option, select" Delete History "one, and keep pages in history the number of days to one day, up to no more than five days.
