i'm still running 10.3.1 on my PB 12" 867, since I can't stand hearing the fan in 10.3.2+!
My problem is that my battery apparently dies at 30% capacity remaining. It ticks all the way down to 30, and then just drops to 0% and goes to sleep immediately. I've tried resetting the power manager, but it hasn't helped. I called Apple, and the guy told me that he'd never heard of this, and that there was nothing to do about it, since I'm the *only* person this has ever happened to
So, I have run the battery update, maybe this is what caused it? i don't remember if it did it before that or not... but its driving me nuts.
OK I'm going to take the dive! Since my PowerBook G4 12" goes to sleep when it gets to only 85% I figure I don't have much to lose and I really need my battery to work. Here's my post to the Apple thread about it, good to see other people are sharing in my misery at least:

Yeah I have this EXACT issue. I knew other people were seeing this and the idiot on the phone @ 800 800 2775 from Edu Apple Care was lying or ignorant when he said no one else was having this problem.
I assume it is software as a I typed in "ioreg -l | grep -i IOBatteryInfo" I got 3426 as Capacity, which is ok for a year old I guess. Isn't the 12" PB 867 supposed to have 4000? Anyway that's around 85% so so be it. HOWEVER: My PB drops to sleep at 85% to and the status light on the battery at that point would be showing 4 or 5 green dots, then all of a sudden to the bottom one flashing. Conversely I watched it closely when it was charging up. It got to around 29% or 30% then shot STRAIGHT up to 100%. Hmm...This can not be normal.
I have reset the PMU, PRAM, etc a lot. I also did one thing one guy on the phone told me: Take the battery out, hit the button, wait 30 seconds, then put it back in, power up, all the way down, then all the way back up, and then all the way back down again. Did this a few times, didn't do anything. Now, my PB sleeps at 85% with the CPU down, drive spindown on, screen off at 1 minute, and all networking, modem, ethernet, AirPort, Bluetooth, turned off.
Damn - My Ti-800 is doing the exact same thing. Sleep at 85% - the minute before, the battery has 4 LEDs, but just after, it has one blinking one.
Even stranger - this is what my battery grep shows:
Capacity = 21695, Amperage = 1200, Current = 21684
whereas a month or so ago, the Capacity was a normal 3300 or so...
I posted a thread about my sudden decrease in battery life which seemed to happen overnight. Well I just did the battery test again, and I now have 'capacity' of 3469

any thoughts?
"IOBatteryInfo" = ({"Capacity"=2626,"Amperage"=1200,"Curren$
what does this tell me if anything?
