I put a lap top on "sleep" mode. Then I closed it. Now I opened the lap top and pressed the "turn on/off" button (which usually takes it out of the sleep mode. And I can hear it working (the fans and all the stuff that makes noises), but the screen is dead black... What should I do?
P.S: I read that removing the battery for an hour should fix the problem. I have to work out how to stop the machine before removing it now. Grrr...
