I have a HP Presario CQ62 notebook that just totally died. I closed it up after using it normally, came back and opened the lid and it was dead. No lights, not even power supply indicator light. Nothing happens when the power button is pushed of course. I thought and hoped it was a faulty power supply and a flat battery, but I have a spare power supply so this was able to be ruled out. Not that it's relevant here, but it's running Windows 7 64 bit. Anyone got any ideas where to look for a solution to this? As it won't fire up on battery or power it has to be after those.
