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.
