DELL M5010 showing
1) m5010 boot no 7 sound alarm
DELL M5010 discrete graphics motherboard boot to about 1.5 A current, wait for A few seconds and then 7 sound alarm, believes that many colleagues met this question, is not A bad CPU, nor is it A graphics card problem, it is A common fault, north virtual welding, need for chipset on the bga baking only, it is the motherboard to all connected to current 2.9 A light machine.In addition, this machine is easy to repair, if afraid against revisionism, it is best to change machine fan long turn.This problem hope can bring convenience to our colleagues processing, three exceptions m5010 motherboard alarm for everyone to share.
2) m5010 boot no 3 sound alarm
The common fault of the three series of DELL DELL M5010 alarm DELL M5010 AMD.Discrete graphics.Three beeping, alarm, the current 0.5 does not move.Is a disease, the same problem has been revised to be IMVP_PWRGD down to 0.7 V.Pry PU5101 first foot is OK.Also can replace PU5101 directly.
DELL M5010 set piece
Doesn't boot around current up to 1.2 A, don't worry about the BIOS or AMD CPU, directly make chipset is good, just need to give A chipset on the BGA baking can!

Teach your ThinkPad laptop Fn key Fun

If you are a new user ThinkPad, it is possible for the problem to worry about the keyboard keys, such as control of the game want to use shortcut keys, but by default it must be achieved in combination with the Fn key, or that when you use the F5 keyTeach your ThinkPad laptop Fn key Fun in accordance with the traditions and customs when you refresh the page, it is automatically turned off the wireless card switch. Because of this keyboard with the traditional ThinkPad keyboard has some design differences.

In fact, in order to meet user needs, ThinkPad laptop BIOS settings, there are options, you can turn on or off the Fn key function is to press the F12 key at boot time, after entering the BIOS setup screen, turn switch to the "Config → Keyboard / Mouse" settings page the "Change to" F1-F12 keys "option is set to" Legacy ".

After setting Press F10 to save and exit, so when playing the game, they can directly use F1 ~ F12 function keys to control the game and so on. Of course, if you do not play the game, usually just browse the web, edit documents, it is recommended Fn key combination to open, when such use F5 or F12 function keys and other random, there would not be such as to turn off wireless network card, misuse of disabled cameras .

In addition, if not accustomed to using the Fn key, Fn key can also be used interchangeably with the Ctrl key, the method is in the "Keyboard / Mouse" settings page, the "FN and Ctrl key swap" option is set to "Enabled" can, so when you use F1 ~ F12 shortcut key, you need to meet in order to achieve real Ctrl key.

17 years of innovation along the way ThinkPad notebook List

IBM's ThinkPad began as a brand, is said to be the origin of the brand within the company's IBM laptop (the kind used for writing), while the laptop's appearance is a reference to the Japanese bento box (because the first generation machine is large and experimental IBM Japan chamber design), the first appeared in 1992 ThinkPad. In 2005, ThinkPad series (as well as ThinkVision, ThinkVantage, ThinkCentre, Aptiva and NetVista) is Lenovo (Lenovo) are bought, ThinkPad become Chinese brand, and this year is the 17th anniversary of ThinkPad born full, that is, over 18 years years old.

ThinkPad along the way, bring a lot of innovation, a simple strip are as follows:

TrackPoint (or should we say Pointing Stick) - also known as "red dot" or "pointing stick", was first introduced in the ThinkPad 700. Invented by MIT scientist Ted Selker, and later in HP, Dell and Fujitsu products can be seen. ThinkPad TrackPoint is patented, is the need to pay for the use of other brands, so not much use other brands.

Built-in optical drive - in 1994, ThinkPad 755CD was the world's first built-in CD-ROM laptop

Webcam - appeared in 1995, at the time of the ThinkPad 755 first time

14.1-inch and built-in DVD drive - in 1997, ThinkPad 770 is the first 14.1-inch screen and built-in DVD drive of a laptop

Thinklight - appeared in 1998, the first application at the time of the ThinkPad T series

Removable drive - launched in 1998, the first application in ThinkPad 600, the drive can be taken out like a drawer-like, second battery can be replaced

Ultrabase - appeared in 1999, also known as "Dock", in order to increase the laptop's expandability, another to design a tank chassis with multiple connections can be installed under the ThinkPad, applied at the time known as the world's thinnest ThinkPad 570

Hardware encryption - built-in hardware encryption chip, to insert something similar to the chip card for the computer, in the ThinkPad T23 2001 as the world's first use of this mechanism for the first time laptop

APS - is "Active Protection System", the hard drive protection technology, in 2003, on the ThinkPad T41 and ThinkPad R50 for the first time using

More than 10 hours of battery life - appeared in 2003, ThinkPad X30 was the first breakthrough in battery life over 10 hours of laptop

Fingerprint - English as "Fingerprint Reader", in 2004, when the ThinkPad T42 is the world's first laptop equipped with fingerprint recognition

Cage protect magnesium alloy frame - English called "roll cage", appeared in 2005, inspired by the car's roll cage, in order to strengthen the body is strong, applied at the time of ThinkPad T / R Series

As for as the spill-resistant keyboard (Spill resistant Keyboard), imitation owl wings cooling fan (to reduce wind noise), metal shaft, etc., maybe not the first to use the ThinkPad, but these have become one of its characteristics.

However, be acquired by Lenovo ThinkPad will guarantee long as the former glory of innovation? I believe the time will give us the answer.

Rejuvenating the old notebook upgrade SSD Raiders

I believe that many readers are still using the N years old laptop, although they run slowly, but not to abandon the standard. So, what method to have to let our old friend re Hwan youth? For the installation of SSD is a very good idea, after all, the replacement of SSD not only can obtain a faster system response speed, alleviate the problem of slow old hard disk transfer speed, but also reduces the amount of palm fever, rest area, then our "super" idea can be in these old laptop dreams come true?
The old play SSD, we need to pay attention to the problem......
First, the SATA interface version. First of all, I want to be on our minds the first definition, we think should be those that do not support SATA-3 hard disk interface chip set laptop.
The SATA interface has experienced three times of the standard theory, the maximum transmission rate of SATA-1 is only 150MB/s, the chip group using the latest interface is the 945M series (ICH7M series bridge); while the SATA-2 interface of the theoretical maximum speed doubled, reaching 300MB/s, also known as SATA 3Gbps, laptop chipset support the SATA-2 interface to the latest 5 Series (such as PM45); the latest SATA-3, namely SATA 6Gbps interface, the speed limit up to 600MB/s, all Intel chipset series after 5 were supported by the version of the interface, such as HM55, PM55.
Should now is not difficult to understand why we should pay attention to the SATA interface version of the problem, because the existing of high quality SSD are the new SATA-3 interface, but your old laptop may even just SATA-1 interface, like if you have good car speed, the road is so broad, can only stem worried. The main board SATA interface speed directly affect the performance of SSD in the test link, later we will carry on the research to this problem.
Second, the capacity of SSD. The performance and capacity of SSD is directly proportional to the same type of particles, and the main control case, the performance of large capacity SSD will be stronger, so in the choice of SSD also must try to choose large capacity version, although the price is higher but the performance is more outstanding. We do not accept "because the SATA interface version of the low, so he bought the small volume or low speed SSD" such view, after all, capital will eventually eliminated, there is also the SSD also eliminated?
Third, the position of the SSD. Recommended to choose the installation location of original mechanical hard disk, although the chipset supports multiple SATA interface, but vendors do not amount to provide so much, most laptops only hard disk with SATA interface is used CD-ROM, and CD-ROM who is very easy to meet the low version of the SATA interface, so be sure to install SSD to the original hard disk position, the optimization of SSD performance so can the greatest degree of.
Fourth, 4K is aligned with the AHCI disk mode. The performance of 4K is aligned with the AHCI mode of SSD play a vital, almost all can drop SSD speed to about 2/3 level, so it must be re partition of SSD, because Windows 7/8 will automatically 4K sector aligned in when creating partitions, and the AHCI model must be installed on the operating system before entering the BIOS is set correctly. Only in to meet the two prerequisites of the premise, performance SSD can get to play.
Test method: using the old version of the SATA interface
Testing models of A:ThinPad X60
Chipset: Intel 945GM
The SATA interface version: SATA-1 (150MB/s)
The test model of B: Haier S60
Chipset: Intel GM965
The SATA interface version: SATA-2 (300MB/s)
In the test the choice of models, we did not consider the latest SATA-3 interface platform, because the new interface nature can fully play all the performance of the SSD, we need to look for is the performance on the old platform SSD actually many restrictions. Testing SSD for Plextor M5S 128GB version.
Test method is through the AS SSD, CrystalDiskMark and FastCopy software to determine the objective, while adding the boot speed testing, in addition to SSD will also with the original mechanical hard disk (320GB 5400rpm) were compared, in order to reflect the experience performance difference, of course, the performance difference between the understanding and the SATA-3 interface is also very necessary.
On the SSD, any SATA interface have meaning!
Even if SATA-1, SSD also can bring upheaval
By testing the mechanical hard disk can be seen, compared to the original, after upgrading SSD even SATA-1 interface speed of the slowest can also bring a qualitative leap, transmission rate increase is very obvious, the response speed of the computer also changed a lot faster. Although the Plextor 128GB SSD performance is running at full speed is very breathtaking (PX-128M5S), SATA-1 interface in old laptop only played the less than half the work force, but this to old laptop case is sufficient to cause the usability of qualitative change, especially with optical drive tradition this, double disk the scheme can obtain quite good balance between speed and capacity, many years ago, we are talking about the "hard disk laptop performancebottleneck", today, we can finally eliminate the performance bottleneck of HDD by SSD.
Special note: note SSD compatibility problem!

In the old SSD platform installation should pay attention to compatibility problems,it is best to first test after the purchase. For example, in our X60 notebook, the Plextor 128GB SSD can correctly identify and use, but Kingston SNVP325-S2/64GB SSD without being identification method.

SATA-2 interface upgrade Gengshuang, but still "individual differences" problem

And GM965 with ICH8M south bridge is the first generation of support SATA-2(3Gbps) chip set, in terms of performance enough to group 945GM with SATA-1 interface is far low behind, naturally, not to mention the weak mechanical harddisk. In fact, equipped with SATA-2 interface and old notebook I believe today is still in a lot of service is, and the test data tells us, this kind of game playerupgrade SSD is completely feasible, usability improvement than SATA-1 is moreobvious, continuous read rate of CrystalDiskMark reached 234.6MB/s, even better than now part of super book SSD. Ofcourse, compared to SATA-3, SATA-2 interface bandwidth is clearly not enough, if you want to replace the greatercapacity of the notebook SSD, SATA-2 is a little bit "calf cart" feeling.

But compatibility problems still exist: in our testing process, and Haier like S60also uses the GM965 chip group ThinkPad X61, we obtained after installing the SSD test scores even than X60, although we update BIOS, but in the end, it does not solve theproblem, although largely notebook individual problems, but for X61installed SSD reader might notice.

Not afraid of vibration without fear of high and low temperature, the capital alsohas the new spring

The old laptop has gone through years of "campaign", the aging of internalaccessories to make its durability is further reduced, and SSD settled first canlower fuselage vibration, after all, it is not the disk and the motor structure, this time do not have to worry about all kinds of vehicle bump will affect the datasecurity. But the mechanical hard disk is very sensitive to temperature, too high or too low will cause significant influence on the performance, itself derived fromSSD in the field of industrial control nature would not be affected by the environment factors. Therefore, no matter from the external structure to upgradeor internal performance, SSD is worth considering for the old laptops. As we inafterupgrading SSD ThinkPad X60 left palm rest area temperature relative does not install before low temperature near 5 DEG C (long time conventional InternetApplications), so, after installing the SSD benefits is still a lot of.

Summary: engineers playing chicken blood as capital, SSD is preferred

In general, the notebook interior upgrade we tend to think of the processor,memory or graphics card first, but few people are going to replace the hard disk,which is just your negligence, through our testing today can see, even the oldSATA-1 interface notebook, in replacement of the SSD after the response speed hasbeen significantly ascension, even if the interface bandwidth is badinfluences SSD performance to play, but after the discount rate is enough to keep the mechanical hard disk to shame. If you want to make savingsrejuvenated it, replacing the processor, the upgrade of SSD, which is the two largest selection of our most recommended, believe that will never let you down.

Optimization of fully manual power Android tablet computer battery

Power consumption is measured, what the most power application

In daily use, the different environment, flat endurance have what different? Here we use common user simulation environment, according to the use of state(including playing games, watching video, Internet) and static state (including retention of common APP running in the background, completely shutdown the third party APP standby) for power consumption test.

Testing equipment: N50 ppt

Screen size: 5 inches, 800 * 480 resolution

Processor: rockchip RK2918, Cortex-A8 (ARM frequency 1GHz)

Battery: lithium ion, 3200mAh

General settings during testing: WiFi open / medium brightness / volume of medium

One, the use of state

Test method: using computer camera recording plate operation state, the beginning of each test after a full charge, until the tablet prompted power is low(low value is set to 5%), during which as a life time value, recharged again after the test of another project.

1 to play the game,

Test the game: asphalt 6, life time: 2 hour 57 minutes

2 see video

The test film: the series "Damnacanthus red", continuous use of IDG Arts +WiFi player. Battery life: 3 hours 22 minutes

3 Internet

Test method: browse the web using the WiFi+ browser of Baidu (including news,photos and online e-book). Battery life: 3 hours 54 minutes

4 see e-books

Test software: iRead+ automatic page, testing is black and white interface TXT e-books, life time: 6 hours 36 minutes

Two, static state

1 screen off, but retain the common background processes, life time: about 27 hours

Test method: because the process is running in the background, the screen is not displayed, so the test is after 24 hours of standby, every 1 hours to open thescreen to see a quantity, time recording when the remaining power about 5%.

Keep the background process: Micro letter (which received about 20information), peas (user commonly used mobile assistant software, the defaultself start), LBE security master, mobile QQ (of which received 25 pieces of information).

2 full standby, the life time of >72 hours (because users are rarely used, in this state were not fully tested, only for comparison).

Test method: after startup, use Android optimization master all third partybackground processes all closed, then enter the "program to set", the master Android optimization process is also closed, finally closing the screen to start thestandby.

From the above test results can be seen, the game of life time is the shortest,after all the game requires CPU and GPU high-speed operation, need more power support. While the full standby due to software and hardware are in a dormant state, so the power consumption is very low (only the systemitself inpower consumption standby). Watch the video and the Internet on the battery consumption almost, and e-books, because reading plate movements are rarely,so the battery can also insist on for a long time.

Computer of notebook on failure treatment experience

Now the laptop price more and more cheap, use the laptop and more and more people, and therefore often encounter this or that problem in the process of daily use, usually we have received many letters from readers advice on laptop fault. For it is in the warranty period of the models, we suggest a direct repair, but to have been guaranteed models, repair may face repair costs hundreds of dollars to thousands of dollars, at this time to try a good way to not lose repair. The laptop is a modular obvious products, sometimes to master some repair tips can help you save a lot of.

Skills: find accessories online

If the laptop down, we can see its composition is relatively simple, is nothing but the shell, motherboard, display, hard disk and memory and other conventional components, therefore the laptop when fault occurs is nothing but the components in one part of the problem, as long as to find and fix can achieve the purpose of dimension. In fact, the laptop repair the direct replacement parts is the most efficient and effective way, and the repair station is often so dry, especially for has been preserving capital, the use of replacement parts is often the spare parts repair. But problems for the laptop, the most troublesome than shell damage, the screen shaft, display signal board and motherboard this four big parts problems, because other parts comprises a display screen, all belong to the general parts, in the market for it is easy to buy.

So in the repair before we might as well go Taobao search, may find a suitable models of the motherboard and other accessories, we only need to buy these parts of self can be. But to be sure, if they are buying a popular models at that time, in the online to buy accessories odds is very big.

But for many users, the most troublesome is to determine where the problem is, in fact, at this time we will be sent to the professional laptop maintenance organizations were detected (recommend to the official authorized repair station for inspection), just for warranty laptop detection, repair station will often charge a fee, but generally not too much. If we can offer affordable direct maintenance, but if the price pit dad, the proposed purchase of parts to repair.

In my own experience, general maintenance station replacement laptop motherboard at the cost of 1500 yuan, and to purchase second-hand motherboard at the cost of 300 yuan; change the display in the cost of 1000 yuan of above, and purchased by the CMO, AUO screen costs less than 500 yuan, the price gap is very obvious.

To have a warranty period threshold Lenovo Y470N laptop, Internet has lots of motherboard accessories in the sales price of about 300 yuan, but to remind everyone is must choose the spare parts with certain of the warranty period, such as three months

Tip two: assembly laptop skills

For many users, is a very troublesome thing disassembly laptop, lane is bad to can also bring the new fault, in fact, laptop dismantling we had been told many times, the traditional laptop disassembly and no imagination in so much trouble, the network has a lot of disassemble Raiders, for part of the PC manufacturer of commercial even a teardown Handbook for users to download, as part of the ThinkPad model.

Generally speaking, if the keyboard and C plane is not integrated forming laptop, we suggest that you first start from the keyboard to start dismantling, confirmation under the keyboard without screw after dismantling the CD-ROM and hard drive and other components, then all the screws of the bottom cover, the triangular skid sheet separation C shell and the bottom shell for demolition after a step by step to basically can achieve the purpose of dismantling. Just need to remind you is, in the dismantling to do careful and meticulous, edge dismantle installation fixed position change photos recorded the screws and cables, meet cannot be disassembled situation must check what is in the way of separation, and not with the brute force of profiteering dismantling.

If it does not have the confidence to oneself, also can bring their own spare parts to Computer City laptop maintenance company please professional personnel on behalf of the replacement, although this will spend part of the cost of the whole is down but still than the maintenance station benefits a lot.

In the process of assembling and disassembling the laptop, attention must be paid to the battery compartment, under the keyboard, the small cover, a medial edge and internal CD-ROM part foot pad below the hidden screw

Tip three: small fault them out

In the above mentioned are serious faults such as notebook motherboard damage, but for the laptop case may also be some small fault, in fact, all of these faults can be solved, below we enumerate several typical fault I encountered for your reference.

The interface loosening. Laptop internal use of a large number of functional modules and between modules are connected through the socket and cable, the cable to connect often only tape simple fixed, if the notebook quality doesn't pass, with a long time may cause the cable loosening and the influence function to use. Encountered such problems may wish to remove the notebook detection, such as touch panel failure, failure, the function of the whole body edge adjacent end interface loudspeaker without sound output, switch on the mobile phone have sound but no display screen are all possible results of the cable loosening caused.

Don't read the disk drive. Although people rarely use the CD-ROM drive, but is still a lot of laptop standard. If they seldom used drive but appeared decreased ability to read the disk or simply do not read the disk of the phenomenon, is likely to be laser head surface dust, then we might as well use cotton swabs dipped a little alcohol wipe laser head, which often play an immediate effect.

Boot no display. Boot no display is a big topic, has very many reasons, such as memory loose, damage to the motherboard, but the face of the boot after the power indicator light screen no display of the phenomenon, in addition to re plug the memory or wipe finger memory, in fact re plug the notebook BIOS battery, take off the battery short time short circuit the battery pin, sometimes also can play a very good effect, but these tips are also a lot of users is confirmed to be effective.

BIOS battery re plug laptop motherboard can sometimes solve some problems

Editor: self maintenance laptop to save money and fun

In the eyes of many users, the laptop is a very mysterious IT products, the internal integration height allows many users to its internal structure is full of doubts, but this not understand also led to a laptop when a fault appears helpless. In the present situation of the increasing popularity of the laptop, a user maintenance laptop demand can only be more and more, and PC manufacturers still high maintenance costs and pit dad parts replacement costs, let many users complained, so there were things 1500 yuan maintenance costs this incredible 3000 yuan laptop.
So for the laptop influx of players, although the above several skills will not be enough to solve the problem, but the idea of all laptop, laptop players Shen Yiyun Liaoning readers still has the certain reference value, notebook internal is not mysterious, and structural modular make maintenance has become relatively simple, the key is that we should have confidence in ourselves in the face of failure, try to maintain that save money and fun, why not.
