When Lenovo laptops play games, the screen always suddenly goes black and it automatically shuts dow

If it is a black screen in use:

1. If the black screen disappears after moving the mouse, you can return to the normal screen, which means that the screensaver is automatically entered, and you can try to disable the screensaver;

2. If you can't wake up the screen after the screen goes black, you can press and hold the power on/off button for more than 3 seconds to force it to shut down and then turn it back on again to see if it can start normally.

3. If it can't be solved, you can uninstall and reinstall the graphics card driver and test again.

If you encounter the problem of "black screen when booting", you can click on the avatar to enter the "Lenovo Business Service" homepage and consult an engineer online to solve the problem.

If it's a frequent black screen and automatic shutdown, it should be a problem with the main version! Power issues will recur without a black screen

This will happen if the CPU temperature is high. Laptop fans are adjustable in the BIOS. I won't, though. Hehe.

It has something to do with the power supply, the power supply may be unstable, you should send it for repair.

You can go to the power options in the control panel and set the standby and adjust the time to turn off the display.

Are you a new machine? It's been a pretty long time.

If the time is not short, it is recommended to go to the chain store to clean the dust.

It's likely that your machine has too much dust, which causes poor heat dissipation, and the CPU temperature is too high, which causes it to shut down automatically.

It is caused by static electricity, and it has nothing to do with the hardware, it is due to the static electricity on the motherboard during use, resulting in no display when booted, just do a reset operation, that is, unplug the battery and power supply in the state of shutdown, press the power button 5 times, and press and hold it for 2 seconds each time.

In my opinion, it may be because you turn on the air conditioner at home, the air conditioner is not refrigerated at all times, and the compressor will cause power surges when it starts, and the voltage will be unstable and shut down. It is recommended that you leave it unplugged in and try to see if it will shut down abnormally.
