I have a 20 month old G4 iBook. I often shut the lid to put it to sleep when I'm away for a bit. Sometime lately I can hear the hard disk spinning up and down, and the system making the sounds it normally makes when waking up, then it shuts back down, wakes back up, etc. Repeatedly, all while the lid is still closed and I'm not touching it. Any ideas? Should I reset the PMU?
Thanks very much in advance for all advice on this, have a great day!
Chris
