my laptop screen went black and won't turn off (used ctl,alt,del).

Answer 1

Do you have an external monitor readily available, plug it in to the laptop VGA port, and see if you get any video by doing that? that's what I do when I get a problem like that, just to remove the possibility that the problem is actually the screen and not something else.

update me after you do that.
