That morning it was working fine. The only thing I can think of is that it got damaged while it was in the bag. But I can't see anything wrong with it.
So how badly is it fucked up? Is there a way to fix this or will I have to get a new laptop?
If I have to get a new laptop will I be able to take the hard drive out of this one and put it in the new one?
Edited to add more info: It's an HP Pavilion laptop, model # G62-435DX. Also the fan turns on when it starts up and the only way to turn it off is to press and hold the power button. Sorry I don't know how to describe it better.
