Pismo: dead battery after 10.2

Message #1 - Posted 2003/04/18 - nospam

shortly after upgrading to Mac OS 10.2 my Pismo Powerbook battery no longer charges. Is this a know problem or did my battery simply die? By the way, my Powerbok is almost always plugged in to AC outlet. I very rarely use the battery to begin with, this is why this all seems odd.

This is a problem that many Pismo owners (as well as owners of other PB's) are experiencing. According to a person who spoke with Apple's technical support (AppleCare), this is a problem Apple is aware of and is working on a solution for. The phone tech stated that the problem, Apple felt, wasn't that the battery had died, but that the firmware that the communication between the OS and the battery charge controller had been corrupted, somehow.

It isn't a problem only with 10.2. I'm having similar problems, and I've only installed 10.1.5.

Stay tuned...

had the same problem after upgrading my Pismo from 10.2.4 to 10.2.5. Battery completely dead and wouldn't charge. I bought a new battery (from OWC) and it seems ok. I hope that Apple will figure out a way to recharge the old one.

I know that this is going to sound like it's unrelated, but I had the exact thing happen with my 1999 tangerine iBook. It had been running at least 3 hours/charge. I updated to 10.2.5, but around the same time I let the computer sleep itself to death, unplugged, probably for a week. When I tried to restart the machine (no pulsing sleep light anymore), no response. Worked perfectly when the AC was connected, but zero percent charge recorded on the menubar. Overnight, no charge. Reset the PMU several times (this iBook's procedure is: shut down, unplug, remove battery, press hardware reset button with a paperclip, reinsert battery, plug in AC, and restart) but no response.

HOWEVER, just before I was about to sell it with a warning about no battery, I tried the reset sequence again, BUT DIDN"T TURN THE COMPUTER ON, just did the reset sequence without starting up. Let it sit overnight. NOW, I'm setting it up for the buyer to come look at it, plug in the AC, start the computer...and it says 2% charge. I stare at it as it turns to 3..4...5%. By the time the buyer is there, it's at 20% and I'm unplugging it and running it without a hitch. I just got a call from the buyer, happy she got a "free" battery with it, saying that it charges to 100% and will go for at least 2 hours, so far, on the charge.

So don't give up...
