Yesterday, my battery was working fine. It ran down to nearly 2% so I turned it off. Today, I went to start my computer up again but it hasn't even charged over night. The little green indicator lights on the back of the battery- the first one, when the battery button is pressed, will flash but then go off. What does this mean? Is it a problem with my battery or is my charger just broken?

    The flashing battery light you describe indicates that the battery is not charged. You might try resetting the PMU and see if it will charge then.

    Please post back if this does not work.

    Good luck!

    I have the same problem. I have tried to reset the PMU, no luck.
    I have a older battery that charges OK. The newer battery (2 months old) worked fine up until 3 days ago. Now I can't charge it past 3%. The older battery charges fine up to 100% so it can't be the power cord.

    If the older battery charges properly and the newer one does not, it's possible the newer one is defective. You might try taking it back to wherever you got it and asking about a replacement.
