Can anyone pinpoint the location of the CMOS / BIOS battery on a G4 iBook 14"? I have viewed the disassembly instructions on ifixit.com. They don't reference it. Thanks
There is no CMOS battery for the iBook G4. Just a capacitor to keep the PRAM juiced during battery swaps. See here
I'm surprised! No CMOS battery??? Thanks for the quick replies. Yes.... the iBook is losing Date/Time settings intermittently when the battery is removed, even with the A/C attached. I will pay more attention to see how it behaves during battery removal. It also freezes after about 40 to 60 minutes of light use.... surfing, watching a DVD, etc. I have not seen any funky video artifacts to hint of a graphics chip issue prior to freezing..... just works fine and then it hangs without warning. The system does not seem hot either. I've cloned the HD to a larger/newer model, I've added RAM (was only 256MB so I popped a 1GB SODIMM in ), I've done the basic HD verify/repair, I've reset the PMU, NVRAM & PRAM. I plan on a complete disassembly, re-applying thermal paste to CPU & reseating the heatsink/fan, unless there is a less labor intensive fix to try. Thanks
If I turn off my G4 laptop when it turn it back on it will reset all date and time information. If I were on my pc I would immediately assume cmos battery but it sounds like there isn't one. Anyone know if the capacitor could be bad?
