ok so the other day i was on my vista basic laptop i closed all applications and i closed my laptop so it would be in the hibernate mode after about 4 hours it was still in hibernate mode so i opened it expecting it to start back up and it never did it was and is a blank screen so i turned it off by holding the power button and tried turning it back on and the screen was still blank im sure its turning on as i can hear it and the lights are on and the keyboard is also on cause when i press caps lock the light turns on this also happens every time i turn it on... nothing comes up on the screen so if you have any ideas i would really appriciate it thank you
