[iBook] How to check battery charging of clamshell iBook?

[Wade Dunham]

I am unable to do this, as both batteries are apparently dead. I did it
with the power supply plugged in, and got the following results:

Old battery:

Voltage=16580
Flags=133
Amperage=$

"New" battery:
Voltage=0
Flags=131
Amperage=1200$

Also, I followed the instructions on the Apple web site:

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

"Resetting PowerBook and iBook Power Management Unit (PMU)". This had
no apparent effect on the laptop.

I called a local company today that works on laptops. They told me they
had no way to check if the charging system is working. I called (at
their suggestion) Batteries Plus to see if they could check the
batteries. Batteries Plus said they have no way of checking the Lithium
Ion batteries.

Anyone have any instructions on using a voltmeter to check the
batteries?

Any other ideas would be greatly appreciated. Thanks.

Wade
