Can resetting the Power Manager too heaps times make happen problems near my Powerbook?

I hold a Powerbook G4 that has be giving me trouble with turning on so I've have to reset the Power Management Unit (PMU) quite a few times by pressing shift-control-option-power. It works, but it is the with the sole purpose way I can attain it to come on now and it will turn past its sell-by date even when sleeping. Is there a method I can resolve this? Does the resetting it too many times organize to other problems like this? Can the PMU be replaced?



I've be thinking about replacing both the external and internal freestyle, but not if it will be a waste of money. Has anyone else have this issue after resetting the PMU??


Answer:

Hi. I'm not experienced with the G4 but I'll hand over a few guesses. The batteries surrounded by a notebook (main power and motherboard CMOS) do wear out. The main mobile usually fails first but slowly. It will hold smaller amount and less of a charge as time (and cycles of use) mount up. This flop mode sounds like it could be starting because once the voltage drops below a sure threshold, even if the machine is surrounded by sleep mode, will cause a shutdown. I would check this first. Good luck!
