[QUOTE="Sur3Mac, post: 935096, member: 113359"] There are only 4 components to the charging circuit: The power adapter, the DC-in card, the battery, and the logic board. Unfortunately, there's no automated test to point out which might be failing. If you assume (I'm not saying you are...) that your power adapter is good, one point of trouble could be the DC-in card, which holds the female jack in the PowerBook that the power adapter plugs into. Anyway, it sounds like you need a new battery in any event. A number of people, including my wife (only she has the 15" model) , are using this one: [URL="http://eshop.macsales.com/item/Newer%20Technology/BAP12AL50RS/"]NuPower AL12 55.5 Watt-Hour Battery for all Powerbook G4 12" Aluminum Models[/URL] . Avoid going cheap on an ebay battery, as there are many just junk batteries available there. If the power adapter, DC-in card, and (to be bought) battery are good and you still have problems, then it's a logic board issue. Hopefully you don't need to go there. Of course you should always get more opinions on the matter, and not blindly go with mine. [/QUOTE]
