    Your iBook may not be correctly displaying the charging info. Try resetting the PMU (power managment unit)

    Warning- Doing so will remove all ram disks.

    If you have a clamshell iBook-
    Turn the computer off and remove the battery
    Press the reset button
    Wait 5 secs
    Replace the battery and turn on the computer

    If you have a white dual usb iBook WITH A RESET BUTTON ON THE LEFT SIDE (very important, check if you're not sure.)-
    Turn off the computer
    remove the battery
    press the reset button
    wait 5 secs
    replace the battery and turn on the computer

    If you have a white iBook with 16mb Vram without a reset button and/or have an ibook with a 14.1 inch display-
    Turn off the computer and remove the battery
    press these keys being sure to not press the function (fn) key
    Shift, control, option, power
    Replace the battery and restart the computer.

    Hope this helps!

    I have seen an adapter that did this to, yet still worked perfectly for charging.
    Test it on another machine somehow to isolate if it is your computer or the adapter.

    I'm having the exact same problem. Right now my battery is all charged up, but the light is still amber. Weird.

    My 15" PB occasionally does this too. I usually unplug the AC for a minute or two, then plug it back in and it goes green after recharging.
