The laptop screen is black when you use it, and you have to force it to shut down and turn it on, wh

There are two concepts of black screen, the first is that the screen is black, but the content on the screen can still be seen under the illumination of strong light, and other functions of the colleague's notebook are normal, such as the external keyboard is easy to use, **still** and so on. This kind of black screen is caused by the aging of the lamp tube of the laptop screen. The second is the overheating caused by the upstairs shutdown, which is also a black screen but black completely, everything on the computer is turned off and wants to shut down, measure the temperature ** Master Lu, simple and convenient to see what the situation caused, and then have to be repaired by professionals.

The times are extraordinary.

1.Is the hardware temperature high? Use everest monitoring. Reinstall the graphics driver.

2.Is it out of warranty? If it is over, you can disassemble the machine and clean up the dust yourself.

3.The warranty period has not expired, so let's look for after-sales service.

4.You go into safe mode. As normal. Fix system errors and troubleshoot the impact of the software. Still black screen or can't get in. It should be a hardware issue.

If it is helpful to you, please be prompt

This phenomenon is generally a typical manifestation of a slight problem with the graphics card chip, which needs to be warmed up. It is often manifested as a virtual soldering problem of graphics card chips. If it is the chip of the NVIDA graphics card door, including the integrated graphics card, if you want to completely solve it, you must change to a new and improved version of the graphics card chip, otherwise it will definitely be **, if it is not the chip of the graphics card door, such as the ATI one, you only need to add soldering.

See if it's a driver issue.

Maybe there's something wrong with the computer program!

It's not a big problem, my computer too, I don't need to do it for a long time, just use it twice, It has something to do with the system, and it generally happens in the colder times of winter.

Visually inspect system issues, not hardware related. It's supposed to be the program that caused your explorer to crash (because you can move the mouse, not the black screen they say). If the safe mode is normal, then there is an obvious system problem (including drivers and other factors).

When the black screen does not turn on, take out the electronic battery on the motherboard, and then short-circuit the positive and negative poles of the battery holder with a pair of tweezers or iron wire and other things that can be used to conduct electricity for a few seconds, and then install the electron.

Try reworking the system (preferably with a different version of the system).

Also, check the hard drive.

Turn on the computer and press F8 to enter safe mode. Turn on your computer in a safe environment so that there is no black screen.

Unplug the battery, wait a few minutes, and then turn on the computer, sometimes this will turn on the computer without a black screen.

Go to the repair shop to repair it, it can be done in a few minutes, don't worry, be calm. If it is in the warranty stage, it can also be repaired free of charge.

(1) The reason why the computer has a black screen when it is turned on and restarts it several times is: the power failure of the host.

2) Due to the serious leakage of the filter capacitor in the power supply of the host, or the leakage or damage of the electrolytic capacitor at the voltage output end, it will cause insufficient charging when booting, and it will not be able to transmit enough voltage to start the computer, resulting in a black screen, when it is turned on several times, the power in the capacitor is sufficient, and the voltage of starting the computer is reached, and it can work normally.

3) Solution: Take off the power supply and repair or replace it with a new host power supply, and the problem will be solved.

What is the reason for the forced shutdown of the laptop after it crashes and the black screen when it is turned on again?

Hello dear, it is possible that the system is damaged due to abnormal shutdown. Generally speaking, you can try to press F8 quickly when you boot up, to see if you can choose to enter the safe mode or the last correct configuration, if you can enter normally, the reboot can be back to normal

The symptoms of your computer not turning on are not clearly described. For example, after turning on, is the display screen lit up, and the brand logo screen appears? Is there an alarm? What's the last image that appears?

If your laptop is still under warranty, it is recommended to take it to an official repair point for inspection and repair. If it is not under warranty, follow these steps:

According to your description, the analysis of the situation where the black screen appears is as follows:

1. If the display screen cannot be lit after turning on, the judgment is:

1. Poor contact between the gold finger of the memory module and the memory card slot or memory damage. It is recommended to remove the memory module to wipe the gold finger and clean the card slot.

2. The cable of the display screen is loose or the solder joints are soldered.

3. Poor CPU contact or damage.

2. If the screen can be lit up after booting, and the screen is black after the logo appears, it is judged that there is a problem with the system, and it is recommended to reinstall the system.

1.Check that the monitor cable is firmly and reliably plugged into the host interface, and then check that the contact between the graphics card and the motherboard's I-O slot is good;

2.If the computer starts normally with another monitor, the original monitor may be damaged;

3.Check if the CPU fan is running;

4.You can remove all components except the CPU, graphics card, and memory sticks, and then power on the computer. If there is a fault in the memory, there should be an alarm sound. If there is no alarm sound, then turn on the CPU and re-detect. If the computer screen is still black, it is recommended to replace the motherboard;

5.Whether the system has installed software and update patches, and if so, uninstall the update files;

6.After installing the software on the computer, restarting the update results in a black screen, just wait for the update to complete;

7.You can go into safe mode to repair your computer, if you can't enter safe mode, please reinstall the system.
