I hit the "start" button, but NOTHING at all happens...) I don't think you have a choice. This just happened to a colleague's Tibook 500. Out of the blue it froze and refused to reboot. Completely dead. It's going off to Apple - our tech support says that the cooling system has died and as a result the machine will not turn on again until it's functional. All the best, Colin.
