Hi all,

I have a iBook G4 1.33ghz running on 10.4.10. As the title suggests, my battery's health is at 89% and it was working fine all this while.

Any ideas why and how to fix?

Appreciate any kind response and/or helps.

These batteries generally last for around 300+ charge cycles and then you gotta get a new one. You csn go to System Profiler - Power and check the cycle count.

It has a cycle of 277. Still shy off 300+?

When I plug-in the power adapter, it would turn orange (indicating charging battery) for a few minutes, then to yellow (at this point, it stops charging).
I can still boot with only my power adapter as well as my battery.

Grh.. what's wrong with it?

looks like your battery is kaput. get a technician to check it out?

in that case try resetting your iBook PMU and see if it helps.

instructions here: http://docs.info.apple.com/article.html?artnum=14449

if it still doesn't work then you should go get it checked and most likely be prepared to fork out for a new battery.

good luck buddy!

aisey...
why my 1 year old macbook have 233 cycle count..
now only have about 67% battery.

it is still under warranty..is it possible to get it replace?

Now the battery charges up to 55% and then stops charging.

Omg...

Looks like it's off to the technician then.
