My computer is fully charged and it’s on, but the screen is black. I can see and move the mouse though. How do I get it to come back on?

Assuming you have already tried to adjust the brightness. You may have a LCD power supply fault. It is common with laptops that, if you can still see things on the screen with it being very dull the screen is not getting the correct power it requires to illuminate LCD.

Why is my screen is still off when I turned on the power?
