Back when my Wallstreet PB was fairly young, the battery appeared to die prematurely. However a replacement battery had the same symptoms. It turned out that there was a bad power control module. I ended up with two good batteries.
Recently both old batteries appeared to be dead. After trying Battery Reset on both, only one was recognized and took a full charge. Then with no other action, the second battery was later recognized and also took a full charge.
The problem appears to be intermittent. Sometimes the Wallstreet recognizes the battery, and sometimes it doesn't. (It will work on a fully charged battery, even when not "recognized".)
Two other intermittent problems have appeared. The fan may come on when the computer gets warm, but it may not, even when too hot to touch. And the computer may recognize the SCSI disk mode adapter or it may not.
Can anyone tell me if all three problems (battery charging, fan turn-on and SCSI disk mode) could be explained by a bad power control module? Or, is the only common factor the main logic board?

Sounds like communication trouble beetween both boards
Try pram reset and powermanager reset. (Try it 2-3 times) Check pram battery
If not, the only way is to change both (expensiv) boards
Connect power supply first to wallet, second to the power book anytime

Robert-
I've tried each at least once. I'll try them a few more times and see if there is any improvement.
I expect the original PRAM battery could be bad. I was told it was a rechargeable battery that only served to keep memory alive for a short time while the main battery was being changed. Since getting the first battery to charge, it hasn't been without power. I'll see if time and date are lost when the main battery is removed.
The local Apple dealer said parts were not available any longer, but I found an E-Bay seller with the logic board for sale.
