Hi Rick
Try this from an apple help site. <www.macintouch.com/laptopbatt.html>
Do try resetting PRAM first. I did it with mine for 5 chimes in a row
after open firmware update and it worked. From 0 - 4 hours in about 5
minutes of soft/firmware jiggery-pokery!

Subject: iBook Battery Problems
I'd like to share a recent experience with my iBook (white, dual USB,
600mHz). I hadn't used it in a few weeks and when I turned it on, the
battery was completely dead. I booted up the machine and was very
surprised to find that the battery wasn't even recognized. There was
a little "X" over the battery icon in the menubar (OS X 10.2). I
attempted to re-seat the battery, zap PRAM (using the key combo upon
startup), and reset the Power Manager. Nothing worked. So I called
tech support and they had me do all of those things over again.
Finally they agreed to send me a new battery.
In the meantime, I decided to try one other thing (after reading
about iBook battery issues somewhere online). I booted into Open
Firmware and typed "reset-nvram", followed by "reset-all". Surprise,
surprise...my battery came back to life and recharged fine. Too bad
Apple tech support didn't tell me to try this!
