Hi all! I've been restoring my PowerBook G4 1.33ghz. It has a problem where if I shut it down it wont boot up again unless I reset the PMU. It also wont wake from sleep. Here are some things I've tried that haven't worked:
- I replaced the PRAM battery
- I removed the main battery as it is completely dead
- I tried resetting PRAM
- I booted into OpenFirmware and did a reset-nvram, set-defaults, reset-all
