Green cable light, batteries won't charge.

crwdns2934249:0crwdne2934249:0:

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?
