Hello all, new member but been researching on this site for a while. I just picked up my second mac, an Ibook g4 800mhz, bought it for $60.00 with a busted HD, upgraded HD to 160g 5400rpm,had an extra 256mb ram chip installed and did a fresh 10.4.11 install. Runs internet (on wifi) great with the suggestions from this forum, I'm sure the battery is toast, it sits at (calculating)with 0% while plugged in. Even for extended periods, did some searching on board for a while. Did a pram and PMU reset, and still same. When I first installed tiger a couple days ago it showed battery charging and I got up to 80%, I started up yesterday and boots up pretty fast for a 2003 machine. I pushed the battery button and computer flashed and reset and battery now sits on (calculating) while plugged in. coconut battery shows - current batt charge current batt charge- 0 mah max batt charge - 3528mah 0% bar current batt capacity -- current batt capacity - 3528mah orig batt capacity - 4400mah 80% load cycles - 203 charger plugged in battery charging- no Like I said, I'm sure the battery is dead, but just looking for a second opinion. Thanks.
