Als de accu dood lijkt hoeft dat toch niet altijd het geval
te zijn:
how to boot into Open Firmware (Option-Command-O-F.)
[Rob Wyatt] 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!
I figured I'd share this experience in case anyone else
out there is having a similar problem.
If you are at the Open Firmware screen and want to start up
into Mac OS, simply type "mac-boot" without the quotes
at the command prompt and press Return to exit Open Firmware.
The iMac should exit Open Firmware and continue starting up into
Mac OS.
Buchmann also reports that, while it has many benefits, the Li-ion
design also has an essentially fixed life, which means you need
to budget for replacement in three years or so regardless of
how you use the batteries, or even if you don't use them at all
