Good Start up chime but will not boot
Get a good chime, drive spins, optical spins ( instal disk now stuck) but machine does not boot. Can not reset pram, get only one chime, holding eject or track pad button or start will not eject disk. Have to hold power button to shut down. I removed the track pad temp sensor thinking it might be in emergency sleep but no change to start up behavior. Battery charges fine.
