yes, and good day.
I have a battery charging issue with my iBook G4 1.2Ghz I did a reinstallation of OS X and once I did that, i noticed that my battery said it was charging, but it wasn't . so i pulled the plug and let it drain all the way down till it slept, and took the machine and reset the Power manager. The next time I tried to charge it, i would get up to 79%, then would stop charging (using a battery utility is said it stopped charging) So, i would pull the cord and wait till it gave me a time, then plugged it in, and it went up to 83%. so I pulled the cord and let it give the time again and then plugged it in. No dice. Wouldn't charge any higher.
I am wondering what to do at this time. I have reset the power manager with and w/o the battery in it, i have reset the NVRAM, the PRAM and anything else I can think of.
Any Guru out there that can help me? this is the first time this laptop has done this.
Other than that, the battery holds the charge for about 1:30 hours (which is about normal for this age of battery and this iBook)
Worth a shot?
And when they mean the outer most pins, do they mean the end ones on each side. Like

let's hope all goes well *crosses fingers*
stuck at 74%. I am out of ideas guys.
Have you tried the token PMU reset, pram zap, and open firmware reset? Also, do you know how many cycles are on your battery? If it's more than 300, be grateful for what you get. To check your cycles, you can check it in Apple System Profiler under Power if you are using 10.4, if you're not - you'll need to hunt down a third party app. (can't think of the names of any as I use 10.4 for the most part around here.
it's 300 some charge cycles. I know that. It's just that before this, the battery count would hit 100% when charged. now after this, it only hits 78~83% tops. Do you think it was a botched install or something?
I will test this theory by trying OS X 10.3 on an external FW HDD. If it fixes the problem, i will know then...
done, done, done and done. No affect so far. I got it booted from an external HDD with 10.3
I let it go to sleep last night, and when i woke it up (this was unplugged, i let it drain overnight) it said it was at 25%, so i will see how this goes
I booted to 10.3, and it works fine. now sitting at 85% at climbing. I just got a botched install
It's a LiON battery, I'm sure. Fully discharging LiON is not a good idea. It can work for NiCD and NiMH, but LiON is a very different technology. Troublershooting and repair procedures are very different.

no problems, battery is at 100% and is doing great!
