What if the black screen of my Microsoft tablet doesn't respond?
What if the black screen of my Microsoft tablet doesn't respond? Oh, so is my home computer.

At present, there are two main reasons for computer black screen, one is hardware failure, and the other is software conflict. The difference between them mainly lies in the location where the black screen occurs, that is, when it is turned on or when it is used normally.

Of course, neither hardware failure nor software problem is isolated in a sense. Try to solve it according to the following ideas. I believe that the black screen will be properly solved soon.

Black screen injury

When a "black screen" suddenly appears after the computer is turned on, please pay attention to whether there is an alarm sound in the PC speaker in the computer. If the PC horn sounds an alarm, then we can initially determine the hardware components that may have problems according to the length of the sound. For example, when the computer is turned on, the alarm sound of the PC speaker is one long and four short. According to this prompt, it is easy to judge that the problem lies in the graphics card. If so, readers can open the case and see if their graphics card is firmly inserted. If it feels a little loose, please re-insert and tighten the video card, and then fix it with screws.

If the problem of insertion mode is eliminated and the card slot is relatively firm, you can try changing the graphics card to another slot on the motherboard. If the user's graphics card does not belong to PCI but is a new AGP slot board, and there is only one AGP slot on the computer motherboard, you can try another AGP slot on the motherboard to eliminate the physical failure of the graphics card. If the graphics card is inserted tightly and the physical fault is eliminated, then there is another possibility that the "golden finger" of the graphics card itself has a problem in normal contact. If this is the case, you can pull out the display card again, and then find a clean rubber to rub it back and forth on the "golden finger", because most of the poor contact problems of this "golden finger" are caused by some dirty things on it.

If the alarm sound of the PC speaker is not long but short when the computer is turned on, but a short and urgent call, and there is a black screen, then it can be roughly judged that there is a contact problem in your computer memory according to the phenomenon. The solution to poor contact is basically the same as the display card, that is, insert * * * and then insert it. Be sure to insert it to the end when inserting it, and fasten the clips on both sides of the memory module.

SDRAM slots on some motherboards are troublesome, because most of the slots on these motherboards are very tight. If the user encounters this situation, he must not use force. They can press the bottom of SDRAM slot on the motherboard with their fingers, and then press the memory with their thumbs. Hearing a slight noise proves that the memory has bottomed out. Finally, they can fix their memories with clips.

There are also some black screens, and the computer will not call the police. At this time, the simplest thing is to analyze the specific problems according to the mathematical "exclusion method". First, check whether there is any problem with the power terminal board, remove the relevant supporting parts of the computer and replace them with some other equipment that can be used to check whether the power terminal board works normally. If there is nothing wrong with the power terminal board, then check whether the connection between the computer power supply and the motherboard is normal according to the normal procedure, that is to say, check whether the motherboard power supply is normal.

If the socket is not connected by mistake, check whether the power supply is burnt out. If the power supply burns out, the power supply fan will also stop running. In some early computer cases, the power supply was often insufficient. If this problem is suspected, please unplug all power cords from the hard disk, CD-ROM drive and floppy drive, and then restart the computer. After the power consumption rate is greatly reduced, see if this situation is solved. If the problem still cannot be solved, please rule out that the motherboard BIOS is accidentally damaged by viruses such as CIH, and whether the motherboard is in poor contact or the welding head is short-circuited.

In addition to the above, with the continuous improvement of CPU frequency speed, power supply plays an increasingly important role in the whole PC power supply system. Some people describe the central processing unit as the heart of a computer. Maybe for a long time, we were too concerned about whether the heart is healthy and strong, but neglected the chassis power supply that can provide power and energy for the heart. However, due to the lack of power supply, it may also cause the computer to have a black screen. The symptom is that you can hear the chassis power fan start normally after starting, but you can't hear the "drip" sound of system error, but the machine doesn't work, there is no self-test process, and a black screen is displayed. If all boards and memories are plugged and unplugged again after cutting off the power supply, make sure that all boards or components are not loose, which is mostly caused by insufficient power supply.

I strongly believe that for your love of computer health, don't ignore the chassis and power supply when buying a computer. Buying a power supply with a rated power of more than 250 watts is a kind of care for your machine. There is one more thing to note here. At present, many power supplies with rated power of 250W on the market simply can't meet the requirements, which leads to another suggestion. Buy power supply and try to take care of famous brands. At this time, the brand is a powerful guarantee for the safety of your machine. If there are many peripherals installed on your machine, such as dual disks, dual CPUs, dual optical drives, SCSI cards or anything else, you'd better find a more powerful (300 ~ 400 watts) or server power supply. As for users of P4, Thunderbird and GeForce3, they must use more than 300 watts of power, otherwise things more troublesome than black screens will emerge one after another.

Soft and bad black screen

Of course, the phenomenon of black screen is mostly caused by hard injuries on the PC, but it is not absolutely so. Soft injuries may sometimes be easier to deceive users. In the process of using our computer, some black screen phenomena may also be soft failures after entering WINDOWS 98/WINME/WIN2000 or even WINXP system (but I haven't found the black screen failure of WINDOWS XP yet, but since there is no conclusion, it can be assumed that it also exists).

If users find that the machine is assembled, there are always inexplicable problems in the process of installing operating system and other software, or even a sudden black screen crash. Here, it is necessary for us to eliminate the cause of the virus, because there are many cases in which the virus causes the black screen in the system operation, but the only solution is antivirus, and there is nothing to say. On the contrary, we should pay more attention to errors or black screens in program operation. The most obvious thing here is the program failure caused by hardware driver problems. This problem often appears on some third-party boards, such as 3D accelerated graphics cards, PCI sound cards, network cards, SCSI cards, RAID cards and so on. The most obvious manifestations of such problems are applications and game software. Frequent crashes lead to a black screen.

For example, when playing Dungeon Guardian 2, S3' s diamond viper 770/GEFORCE 2PRO accelerated graphics card is often rejected by the game (the graphics card is not recognized), and even the game will give up hardware acceleration and use software special effects instead. This paper analyzes the reasons for this problem, mainly because the power of standard 3D acceleration chips or higher-end, newer non-mainstream 3D acceleration chips is ignored when writing the game source program, so the hardware support of the game itself is not satisfactory, which also affects the performance of the product. Another example is PCI sound card, PCI network card and so on. Due to the conflict between the driver and the system application, the machine suddenly appears black screen or restarts during operation. Readers can solve this problem by installing updated drivers.

I can only give you so much.

Microsoft flat black screen word file has no flat black screen. It is recommended to try the following:

1. Insert the tablet into the charger to see if it can be charged. The battery may be dead, and the tablet will automatically turn off.

Why is my Microsoft tablet boring only when the mouse is started? Forget it. Let me help you solve it. I think you should install a pirated system.

That is, there is no need for you to patch pirated WINDOWS. When you first installed it, you thought it should be good, but after you patched it in 360 or Kingsoft, there will be a black screen (this black screen is actually a patch made by Microsoft to crack down on pirated Windows systems. I think you will have this problem only if you patch it. ..

The SD card slot of Microsoft tablet is not responding. It is recommended to install a small SD card that can be used on the mobile phone and then insert it. Insert this small SD card that can be used on the mobile phone after shutdown and restart, or after factory settings are restored. After restarting, if it is still unrecognizable, you can contact the seller or after-sales personnel for inspection and maintenance.

The tablet won't open. What if the black screen doesn't respond when charging? Power supply is insufficient

Insufficient external power supply causes some old monitors or some monitors with high power consumption to fail to start normally, which is also one of the reasons why the monitor itself fails to cause black screen. Or the external power supply voltage is unstable, too high or too low may cause the display to fail to work.

The switch circuit is damaged.

The failure of display switch circuit is the main reason for the failure of display black screen. Simple as power switch damage such as internal short circuit, common as switch tube damage or its peripheral circuit components (lights) damage and so on.

The line output circuit is damaged.

The failure of line output circuit or picture tube and its power supply circuit is also the main reason for the failure of display black screen. Especially for some inferior brand monitors that have been used for many years, it is more common that the high voltage package is damaged and the black screen is not displayed.

My tablet computer is black, what can I do? The most common reason why a tablet computer can't boot is that some software is incompatible with the system, which leads to the system crash. Or you can modify the files of the tablet by yourself, or you can't boot after uninstalling the system configuration software that you shouldn't uninstall.

The most common solutions:

Press the reset port (that is, the reset hole), find a toothpick, ballpoint pen or the like, find the reset port of the flat body and poke it in, then try to turn it on. If it doesn't work, poke it again and try again (you can also try to press and hold the power button 10 second or more to see if it can be restarted, and some machines need to poke 10 second or more to start).

Tablet PC brushing steps:

① Download the firmware package of the corresponding model from official website (no matter what brand of your tablet is, you should look for official website).

Under normal circumstances, after the firmware package is decompressed, there will be many files in it, including a brushing tutorial. Just follow the tutorial. If you don't understand Baidu, ask other users.

(3) When sufficient power is needed, brush the machine.

④ Back up important files and software before brushing.

It should be noted that each brand's brush method and brush firmware package cannot be universal. Don't use third-party software to brush the machine. Only officially provided software and methods can be used. It is recommended to brush the machine on WIN7 and XP computers, and it is best to install drivers. WIN8 brush machine generally needs to turn off the forced signature of the driver to succeed.
