Title:
Green cable light, batteries won't charge.
Text:
I have a 15" AL PowerBook G4 (1.67Ghz) with two Apple batteries. Both batteries are 3-4 years old old but worked up til a couple months ago.
What happens now:
* Power cable light stays green whichever battery is installed
* Menu bar battery icon shows power plugged in, 0% charge for both batteries
* If I shutdown, unplug power, plug it back in, and startup I get a "You're computer's clock is set to a date before March 24 2001, etc." warning dialog
* Sometimes when I restart or swap batteries the power cable will go orange for a few seconds but the Menu Bar icon never moves off 0% and the cable always goes green after a few seconds
'''Battery #1'''
* Charge remaining (mAh): 0
* Charging: No
* Full charge capacity (mAh): 1973
* Health Information:
* Cycle count: 334
* Condition: Good
* Battery Installed: Yes
* Amperage (mA): 0
* Voltage (mV): 4133
'''Battery #2'''
* Charge Information:
* Charge remaining (mAh): 0
* Charging: No
* Full charge capacity (mAh): 943
* Health Information:
* Cycle count: 0
* Condition: Good
* Battery Installed: Yes
* Amperage (mA): 0
* Voltage (mV): 7529
What I've tried:
# Resetting PMU
# Lots of battery swapping and cable jiggling
Suggestions? I have to open the computer to replace a noisy fan anyway so replacing stuff inside is not a problem.
Does the clock issue represent a PRAM battery failure? Could that cause the main battery to not charge? Maybe the PMU reset doesn't work without a functional PRAM battery?
