My battery has stopped charging. Everything else seems to be fine. The charger is promptly recognized when connected, it works well with AC power, but the damn light is always green and the battery doesn't charge.
I've tried to reset PMU as per Apple instructions, and I've tried to reset nvram booting in Open Firmware. The problem still exists.
Any idea?

Take it to an Apple store, it might just be a bad adapter.

Even if the light ring appear to not working, it doesn't necessary mean the adapter is bad. Watch if the software recognise it to charge, that's what matter. If you have it under warrenty, contact Apple.
