I recently bought a new battery and new charger from powerbookmedic.com (the apple branded ones are way too expensive) and everything worked find for about 3 weeks. Then suddenly the battery icon got the dreaded 'X' in it, I did some troubleshooting myself, upgraded firmware, installed battery update 1.1 and reset the PMU and still nothing. So I called apple only to find out that my iBook is out of phone coverage but the guy was still nice enough to try to help me and he had me do everything I had already done and then he said the only thing he can think of is a failing logic board. I came to that conclusion myself, but I don't want to accept it. Anyone have any ideas?
