I have a toshiba Satellite laptop, yesterday i was installing mafia 2 and after when i went to the toilet and came back i saw computer like in sleep mode. the fans working, the light indicators are on, everything except the screen. When I force shut down my laptop and switch it on again, the toshiba logo isnt appearing. I've tried all the instructions on the other threads(Removing the battery and the power supply and holding down the power button for 60 seconds). But its not working. Can someone help me cuz i want to play mafia 2 so badly?
