Suddenly Sleeping 12" Powerbook - help!

Hiya

I just bought a 12" powerbook, the old 867Mhz model with 256Mb RAM, superdrive, 60Gb, OS X 10.3.2 installed 3 days ago by me and all updates applied.

3 times now, when the battery gets to around the "1 hour" left mark, the powerbook will suddenly sleep, and not respond to anything until I plug in AC power. I suspected a dodgy battery, but I'm open to the possibility that it's a software fault. The log from the last time it happened is at the bottom of my post -sorry for the length, wasn't sure how much to include.

I'm new to the Mac, having ditched my XP after playing with a friend's iBook. This is a second hand unit, but is in excellent condition: should I be speaking to the seller?

Really appreciate any/all ideas people may have - I want my baby to work!

Cheers
ben

There was a battery update installed 09th Jan 2004....

Is this just massively under/overestimating the amount of juice I have left?

Is there a 3rd party piece of software that will tell me how full the battery is without referencing Apple's figure, if you see what I mean?

Like I said, I'm new to Apple - is this sort of shoddy update common Can't see a way to uninstall the update...

/ben

Now it's charrging, and has gone from saying 1h14m to full (which seemed reasonable at 23%) to 3h47m until full, which at 77% seems very unreasonable.

Gnngh.

So, do people think it's software or battery related?

Mac discussions has no identical problem, but I have posted a q there as well. Here's hoping I haven't bought a duff...

How do I check what sort of warranty I've got?

Cheers ppls

Ben

What are my pram and pmu, and how do I go about resetting them?

Can't find anything like it in help...

Solved

For the benefit of future generations, and the other guy with the same problem:

Works fine now - suspect unit hasn't been used for a while and has gotten confused.

All I did was reset the Power Management Unit (PMU) as suggested - see http://docs.info.apple.com/article.html?artnum=14449 for full instructions. I also did a battery calibration, ie full charge, followed by full discharge until sleep, and then full charge.

Cheers guys.
