There are many people having this problem. Go to the Powerbook forums at 
Apple/support to read all the messages!

My computer has this problem too. After having spend one week of software 
installation and tuning of this new machine it makes me crazy because it 
seems to be a hardware problem and I shall probably have to reformat the 
hard drive and try several other (unefficient) software-related solutions 
while the problem is hardware-based (power management unit is defective). 
On my tiBook, this problem also makes the computer having difficulties to 
start. I must "re-start" it (Cmd-Ctrl-start) rather than start it the 
regular way. And most of the times I have to do it several times before it 
boots!
