1999年7月苹果发布消费级笔记本电脑产品 iBook G3。

Why won't my clam retain the date after it has been unplugged?

It has a brand new battery which it won't acknowledge... hmmm...

The iBook has no backup battery to retain time and other settings when the main battery is removed. A small capacitor holds enough energy to maintain PRAM contents for 20 seconds, so switch batteries quickly.

If it won't acknowledge the main battery you have a bigger problem than worrying about the date. I would check for corrosion on the charger board.

Here's a blowup on all the parts: http://ep.yimg.com/ca/I/lovemacs_2122_37...
