EDIT: Zombiepig - thats an excellent idea for testing! try unplugging the USB reciever from the machine while its hibernated, and plug it back in or into another USB port. when you press a button on the remote, the LED on the reciever should light up indicating its powered.
If thats the case, then its not a hardware/jumper issue. its definitely an OS settings issue.
Ok, so you're saying my problem is OS issue? I'll try the tool linked to earlier and see if i have any success with that
