Hello, have a look at this article if your screen won't turn on or turns off on its own.

Regards
The screen might remain black when there is a corrupted graphics driver or a problem with the LCD display back light. To test the display, attach an external monitor and restart the computer. This test is helpful if the display is black but you can hear that the computer is operating.
