I've had to reset the pmu (shift-control-option-power) four times over the past month or so to revive the sucker.

I have a new 1GHz G4 iBook at work. Good bang for the buck. But anyway, I've had to reset the pmu (shift-control-option-power) four times over the past month or so to revive the sucker. The obvious answer is to cal lApple and say "what's the deal"? Anyone else had a similar experience, or did we get a lemon?
