How to Fix Computer/Laptop Screens Turns Black

While using your laptop then your screen turns black, then try this:
Try pressing the F8 button a couple times during the start up (before Windows logo appears).
It will then list a bunch of options such as Safe Mode or Last Good Configuration. Try Safe Mode first and if that doesn’t work try Last Know Good Configuration.
Once you can access Windows try restarting normally.
If you think your F8 button doesn’t work, it is either you are missing the timing on when to hit F8 or your keyboard button doesn’t work. Try another keyboard or hitting F8 continuously from POST till it comes up.
