I have an iBook G3 800, Airport, 80 GB HDD & 640MB RAM. I tried to turn it on yesterday but it doesnt start at all. No start-up chime, nothing. Maybe because I left in my friend's car for a few hours with Texas heat while I played paintball? I know the hard drive still runs because I can feel the heat from it. the caps lock and num lock buttons light up but I can't see anything. but with no success. Help me please!
