A new way to resuscitate a dead battery
Authored by: firthy374 on Jul 21, '03 11:11:04AM
In addition, the "set-defaults" command should come between these two as follows:
reset-nvram
set-defaults
reset-all

A new way to resuscitate a dead battery
Authored by: airdrummer on Jul 21, '03 01:04:09PM

well, my 4mo.old battery tech clamshell battery was starting to lose capacity (would only charge to 90%, 88%, etc) so i reset the pmu per apple's instructions, did the OF resets (minus the set-defaults) and the ibook refused to charge the battery(green, no amber)-: swapped in the original apple battery(which only holds 1/6 of its original charge, ~30mins) and it charges fine...

so what killed my bti battery?

A new way to resuscitate a dead battery

I am a wallstreet 250 owner with openfirmware 2.01.
reset-nvram is not a known command.
What am I doing wrong?

My battery is still dead after all the reset and insert-extract procedures.
Is it really dead?
Many thanks
Paolo

A new way to resuscitate a dead battery

I just tried this on a dual USB iBook of newer model (out of warranty by 5 days) with a battery that wouldn't take charge. The iBook would die immediately when pulling the power cord. Resetting PMU would not help.

This cure worked perfectly.

It worked for me too!!! Thank you very much!

I have the same ibook G3 model. It was a gift from a man who didn't know what to do with it. Now is like new. I'm using it with OS X 10.4. Yes, slow response but enough for read or listening itunes.
