i have a Apple iBook G4/1.2 12-Inch and every time i shut it down and reboot it the date and time are changed to like 1969????!!! I have to keep changing it back to the current date and time. i know on some G4 towers there is a battery u can replace when this happens. Is the process similar on a iBook????!!!help

Yes, look to the battery first. Take a look at these.

Thanks, but those links didn't really help. Thanks again for trying though.

This is what I tried so far: Starting the ibook with the battery only and i tried starting the ibook with the power only ( battery removed) and i still get the " Time and date error issue".......If i reset the PMU, what are the consequences ????? I dont want to screw up my iBook???

This Apple Document (http://support.apple.com/kb/HT1431) talks about a PMU reset. You'll lose some basic settings nothing to serious... I can't remember exactly as it's been a while. ;)

Looks like your backup capacitor has given up. it's soldered onto the board, I've never bothered to change it as you can sync with apples time servers provided you have an internet connection. this is the simplest solution. it can also make it hard to turn on the machine. this canusually be overcome by using a power adapter and holding down ctrl, fn, shift and power.

FYI - I reset the PRAM and all is well. I reset the clock and date and tested the ibook by rebooting it several times throughout the day and week and it appears to be working fine, cool !!!!!!!!! Thanks !!!!!!!
