When I woke it up this morning (after being plugged in all night, as usual) it said there was no battery present. I tried resetting the nvram (from open firmware) after trying to reset the power manager, all to no avail.
Just out of curiosity, I swapped in the battery from my wife's 600mHz iBook and it ran and charged it fine. My battery has just up and died, apparently. It shows up as dead in the 600mHz iBook as well. Any ideas? I hardly ever use it on battery power so I'm stunned that it would just die like this.
Any info is appreciated.

My 17" powerbook has just started claiming it has no battery installed,

Does anyone know what can cause this in this model?
The one way I've figured out to get it to see its battery is to pull it
out and snap it back it - a pain since it's on the bottom, plus it
doesn't work all the time any more (or for very long when it does
work).
I've tried restarting, resetting the PMU (using Apple's instructions
for this powerbook), and using the battery update software from Apple's
site (which isn't described as solving this problem - in fact, the I
only remember seeing the "x through the battery" problem mentioned in
conjunction with WallStreets, and couldn't find any mention of it
happening to Aluminum G4s). None of these helped.
It should be under warranty still, and definitely has a CompUSA
extended warranty (I got the floor model from there), but CompUSA is
inconvenient to me - over an hour - and I wanted to know if anyone here
had an idea what the problem might be (battery? PMU? other?) before I
check out the local Apple repair site or hit the road for CompUSA.
How long did you have it? It could be the battery running out, but since
it's a 17", I would think something else is at cause, like the PMU.
