Message #1 - Posted 2004/06/02 - John

sorry for the dumb question, but i have a friend who's clock is not keeping time. is there still a clock battery in powerbooks made over the last 3 years, or does it simply use the main battery?

thanks for your response

okay... they have "pram backup batteries", so the term clock batteries no longer works...

Yes, of course. How else do you think the clock would stay accurate when the powerbook's main battery dies? Your friend should check the documentation for his Powerbook.

This doesn't seem to be the case for clamshell iBooks, though. My mother's tangerine iBook's battery died, and whenever the power cord was disconnected the clock reverted back to 1904.
