I'm on the new 10.2.8 [1] on a 600Mhz iBook.
Now my battery life (or more specifically, the display) is all over the place. Unplugged, it rapidly (ten minutes?) drops to 0%, then stays there for anything between an hour and 2.5 hours. Then it either sleeps as normal, or sleeps without warning, or turns off without warning (!!) or sleeps - without warning - for one 'pulse' then turns off.
Annoyingly, even after it turns itself off, it 'recharges' from 0% to about 10% in fifteen minutes or so, then leaps immediately up to 100%. So the battery seems to be holding charge, but the software is in a muddle.
Anyone else seeing this?
I've reset the PRAM and am keeping on eye out for changed behaviour. Any other suggestions?
I've already killed one battery with the problematic 10.2.4 (or .5?), I don't want to have to replace this one too.

[1] Updated to the old 10.2.8, said "whoops", archive & reinstalled 10.2, then re-updated to 10.2.6... then when the new 10.2.8 came out I waited until it seemed safe, then updated.

I got talked through resetting my machine by AppleCare back in July. IIRC (but my scribbled notes are at work) I did the Command-Option-P-R thing for three boots, then Command-Option-O-F and typing something like reset-nvram and reset-all. Does that sound like what you did?
Aha: this looks familiar:

So much for that. Five minutes off battery now, and turns straight off.
Feckit.

I don't own an Apple laptop (although my CC is straining in the wallet thanks to the new iBooks), but I have read that the full 10.2.8 combo updater may help.
Combo updaters have caused fewer problems than the incremental ones have, IIRC. Might be worth a shot?

Hi. Mine did that for about 2 months. Then died completely. Not even recognised. Started doing this after 10.2.4 update I think.

Aha. That's the procedure I've been unsuccessfully googling for.

Bingo, thanks. I will try that, as well as the recalibration instructions at
<http://docs.info.apple.com/article.html?artnum=86284>
Really odd behaviour going on here; the power cable light is green and the display at 100%; yet the battery level lights (on the battery itself) are constantly flashing a single light; press the button and it flashes 4-0-3-0-1-0-1-0-1...
Odd, odd, odd.

Yes; my 10.2.4 update fucked the battery, but I got Apple to replace it FOC. Don't think I'll get them to be so kind a second time.

Yes, definitely.

It was good in 10.2, and seems okay in 10.2.6 (no intermediate stages). I've not been running it much on battery since the 10.2.6 combo update, but it appeared to be behaving itself.

Absolutely no problems here either, touch wood. I've been using the non-combo updates too.

It gets odder.
Left the 'book on charge for a few hours. During that it started flashing 1-0-1-0-1-0-4-0-1-0...1-0-4-0-1-0-1-0 etc by itself (no pressing of the test button). When I came back it was steady 1, nothing happened if I pressed the button.
Actually opening it up and letting it do its thing, checking and occasionally logging details from x-battery, I've been getting this (from the moment I woke it up). Leading zeros as an attempt to keep things tabular.
24/10 01:20 000% 00.00v 1051mA 24/10 01:35 099% 12.28v ????mA 24/10 01:36 100% 20.11v 0752mA 24/10 01:38 099% 20.44v 0678mA 24/10 01:39 099% 11.80v 0976mA 24/10 01:51 000% 11.96v 0679mA 24/10 01:53 099% 12.52v 1200mA 24/10 01:54 100% 12.34v 1200mA 24/10 02:06 099% 12.28v 0756mA 24/10 02:07 000% 12.40v 0978mA 24/10 02:08 100% 12.34v 1200mA
I can't see any pattern here. Well, I tell a lie, x-battery's graph is making a rather pretty pattern, lots of vertical lines. But I can't see any regular pattern, and I'm not clueful enough to know whether the majority of changes in voltage and ampage are just down to noise in the sampling.
Curiouser and curiouser.
I haven't yet pulled the plug to see what will happen next time it decides it's at 0%...

Battery also absolutely fine here on 10.2.8 from non-combo.
Fine in Panther now too.
