Question about Apple iBook G4 (Z0AZW13397068) PC Notebook
My G4 ibook computer keeps shutting down and losing the clock setting
Replace the on board capacitor with a Panasonic Capacitor 5.5V 0.22F Model number:EECS0HD224H cost about $3 . You will need to desoldier and soldier the new one on, it's easy even for a novice.
It is a kind of on board battery contrary to what most idiot mac users say as a battery IS a form of Capacitor.

IBook G4 does not have a CMOS battery but a capacitor to keep the PRAN juiced during battery swaps... my guess is you need a battery replacement of the laptop...

Some computer react this way when the logic board goes bad or have a defect in it.
First, Try this:
Remove the battery. Plug back in the power cord, then press and hold down the power button til you hear a loud beep sound. then release it. If the computer starts back up... Then you should be okay.
If not, it may has something to do with the logic board.
Let me know if the above works... We may can try some other things if not.

Resetting the PMU is not intended for resolution of a stall or situation in which the computer is unresponsive.
