Don't forget:
SIMPLER -- Reset the PMU by playing with the reset button on back.
The correct procedure for PMU reset is: remove battery, plug in AC.
Hold down reset button for 20-30 seconds, release. It may take a lot
of repetitions for this to work!
MEDIUM-COMPLEX -- Take the 2400 apart as if you were going to install
RAM, not a full disassembly. The internal PRAM / PMU battery is
connected to the motherboard by a small 2-pin connector near the
front of the logic board. There is another one which looks very
similar which is for the internal speaker. I don't remember which is
which, so just unplug them both (there's no chance of mixing them up
when you put things back together as they're far apart), and let the
machine sit for several hours without any power connected.
