I noticed something with my 12" iBook G4 that I recently picked up. It would keep forgetting the time and date every time I remove the battery. PRAM reset didn't resolve the issue. I discovered that none of the iBooks and the 12" PowerBooks have PRAM batteries. Those have PRAM capacitors, instead. Oh boy.
The PRAM capacitors are relatively inexpensive, but the procedure is difficult. This is what the PRAM capacitor looks like:
I could not find a guide by iFix for the step-by-step procedure for the PRAM capacitor. However, getting to the logic board iFix has the steps for various iBooks and 12" PowerBooks. For the 2004 12" iBook G4, this is the guide:
Then, the location of the PRAM capacitor depends on the iBook and 12" PowerBook model. For the 2004 12" iBook G4, the location is shown below:
