I recently had problems with an ibook clamshell that did not charge the battery. I tried using the battery reset method but that did not work. I decided that I would go ahead and install Panther (that's as high as that ibook can go) and buy a new battery later. Well to my surprise once I installed Panther the battery started charging again. I don't know what that was all about but I am happy I did not have to purchase a new battery. If anyone was having a problem similar you might want to try upgrading the OS. Also if anyone can explain what happened, please respond! ibook clamshell 466mhz 128mb ram Os 9.0 upgraded to Os 10.3.9 (BIG improvement).
