Re: Is it the hard-drive or something else...?
Indeed, Dodge is right, I doubt a hard drive error on its own would make a laptop not respond completly. It just wouldn't be able to find any bootable drives and not carry on booting to Windows.
It's possible, since the hinges on laptops act as buttons, i.e, pressing the lid down sends it to standby, that something has damaged within the screen, causing it to short circuit or something of that nature.
Still, it should be under warranty. I wouldn't pay this computer engineer to open it up and test it.
