Why does my iBook always reset the date and time?

The iBook G3 does not have a PRAM battery. It uses a small capacitor to store a small amount of electricity to "cover" in the event that the regular main battery is switched and the AC Power supply is unplugged. However, this only lasts for 20 seconds, then it dies. Your main battery has probably gone bad and the date and time information are lost when the AC is disconnected. You printer may also be getting lost.

Resetting the power manager also resets date and time settings. After the reset, on some iBooks and PowerBooks, the system clock is set to 00:00 (GMT), 01 Jan 1970 for computers with Mac OS X or 00:00, 01 Jan 1904 for computers with Mac OS 9.
