iBook fan spins
My iBook has been slowly breaking and has finally gone today. It started with the screen sometimes not turning off when I closed it, then the screen remained black when I opened it. Just yesterday it started going black while I was using it and once it booted up but the 'Starting Mac OS X' window remained in the center of the screen. Today, when I power on the fan spins and doesn't stop. The display does nothing and I can't activate Target Disk Mode etc.
Is this a logic board problem?
