Hey All I recently acquired a Power Mac G4 (Sawtooth/AGP Graphics) 450 MHZ machine. 256 mg of SDRAM It is currently running Mac OS X 10.4.3 (8F46) (Tiger) and everything is updated. This is my problem, every time I turn the computer off and turn it back on again, the time and date resets to Wednesday, December 31, 1969 at random times. Now, I'm only really familiar with PC machines and I know errors like these usually have to do with the CMOS battery, is the same true for Macs or am I looking at a completely different problem/solution? Any help on this problem would be great. If you need any more information on my system just ask.
