Virtual1 - should I understand that the power management chip is not independently replaceable? that I would need to replace the entire logic board? And you are recommending that I charge the battery, take it out when fully charged (and run the laptop off the power supply), and put the battery in only when I need to use the laptop away from the power supply?
Correct, correct, and yes.
There are companies that make drop-in chargers for said batteries also.
