PowerBook G4 15" 1.67GHZ Had an older battery (replaced as part of recall) that was not charging. I replaced the battery and AC adapter, which was also flakey. Still not charging. After resetting PRAM and NVRAM, decided to replace the PRAM battery. Still no joy. Is my next step to replace the DC IN?
What color lights are you getting on you AC charger jack? Please download and run Coconut Battery so we can get a better idea of what’s going on. There’s a new version but I don’t know if it runs on the older machines: http://www.coconut-flavour.com/coconutba… We are probably looking at either the DC-IN board or the battery connector. Visually examine them for corrosion. Please let us know your results. Thanks
This is a year old question. So, I may be too late to answer it, but I had the same problem. Coconut showed battery life good, charger connected, charging no. I removed the battery with the laptop bottom facing down and a little screw fell out. I reinstalled that battery screw and tightened up the other screw too. In my case, that did it. Now, the battery is charging again. Good luck.
