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!

I had this problem on an iBook, and it was because the keyboard was not laying flat -- it happened after I'd opened it up to add memory. So closing the lid would cause it to sleep, but the space bar was warping up and getting pressed by the lid, which would wake it. Then it would notice that the lid is shut, so it would sleep again, and so on.

My Powerbook G4 was knocked off the sideboard by the cat, and as a result the lid won't stay shut.
To have it go to sleep when I close the lid and NOT wake up until I hit a key, I entered
sudo pmset -a lidwake 0
in the terminal.
Presto! The Mac wakes up when I tell it to.
