Hi
I have a little difrent problem. My laptop(toshiba 7 year´s old) blacks out 1 sec after I lift up the screen, and then if goes black. If I close it and open it again it works for 1 sec again, and then goes black again. After a restart I could se a check with numbers going up til 5000 and somthing when it stopped. I couldn´t see what els it sayed in the 1 sec or les it shows. But when i connected the pc to the tv, i could emty all important stuf to an external HD. 1 month ago I had the same problem as the others here. And it was resolved by doing the same thing as they did.
