So what about the laptop black screen ? The following decoration home decoration network Xiaobian will bring you the reasons and solutions for the laptop black screen, I hope to help everyone.

What should I do with the laptop black screen?

Cause 1 , sleep causes the laptop to be black:

Sometimes after turning the notebook screen or leaving the computer for a long time, or accidentally pressing the notebook sleep button, the notebook sleep button is the power button, and the computer sleeps. Many friends who don't understand computers are often caught off guard by such a situation. If the computer is asleep, press the power button and be careful not to press it for too long. If it is more than three seconds, it will definitely shut down. You can also set the notebook screen to never sleep when it is rotated or when the lid is closed. Open Control Panel -> All Control Panel Items -> Power Options -> Edit Schedule Settings -> Put the computer to sleep: "Never". Sleep is set to never sleep or set the way you want.

Cause 2 , computer system damage or poisoning caused the laptop black screen:

If the computer system is damaged or poisoned by a black screen, this is a good judgment. Directly restart the boot into the bois interface or press F8 to see if you can enter the safe mode. If you can boot the bois interface or enter the safe mode, the hardware itself is not bad, just the operating system problem. This is much simpler, just reinstall the operating system.

Cause 3 , hardware damage caused the laptop to black screen:

The most common and most critical hardware that can cause black screens are power supplies, LCD monitors, memory sticks, hard drives, motherboards, etc. This requires us to eliminate them one by one. (1) First, check the power supply, see if the laptop battery has power, and whether the power plug is plugged in. This only needs to see if the power indicator light is on. If there is no external power supply, plug it in with an external power supply. (2) If The power indicator light is always on and the external power supply is also plugged in, indicating that the power supply is ok. At this time, check carefully whether there is wind in the cooling fan port of the notebook, and whether the hard disk indicator is on. If the cooling fan, the hard disk is no problem, restart the computer to boot, carefully put the ear on the notebook to hear if there is a "drop", or always "drip" sound, if there is always a drip alarm sound, then the notebook memory Loose, open the machine and re-insert it yourself. Generally speaking, the memory stick is not easy to break, and the probability of looseness of the notebook memory stick is not large; (3) The above steps are excluded, and it is necessary to detect the problem of the video card or the liquid crystal display. First of all, we need to prepare an external display, which is the best for the desktop. Connect the external display to the external display interface of the notebook. This line is the line that connects the desktop display to the host graphics interface. If the external monitor is connected to the notebook, start the laptop. If the external monitor shows that everything is normal, the notebook motherboard, CPU , hard disk, graphics card, and memory module are all fine . That is the problem with the notebook LCD screen. If such a problem arises, it is recommended that you do not have to make it yourself, and directly look for after-sales or repair site inspection. If you can fix it as much as possible, you can't repair it and change it to a new monitor screen. If the external display does not show anything, the motherboard or graphics card is broken. Generally speaking, the chance of a hard disk is much smaller. Basically, it can be said that the graphics card is broken. The video card is burnt out or the line connecting the motherboard to the graphics card is broken. Because the notebook graphics card is soldered on the motherboard, the graphics card is broken. Change the motherboard. However, if it is only a bad place to weld, you can re-weld it.

Cause 4 , the temperature is too high, causing the laptop to be black:

It is also possible that because the notebook temperature is too high, and often play games and the notebook heat dissipation performance is not good, there will be a direct black screen and a flower screen. At this time, quickly shut down, take a test to see if the graphics card has burned out, if the graphics card is not burned, you only need to completely remove the dust from the notebook, re-clean the exhaust system, apply silicone, and change the fan.
