    I have an Acer 4601WLMi laptop and I fear that the internal battery
    charger circuit has died. My screen keeps blipping between full
    brightness and reduced brightness (as for battery power) and the
    charge LED on the front of the unit does not always light. Also
    needless to say the battery is not lasting long....

    Can anyone please give me some pointers of how to perform a repair and
    or what and where to look as its driving me mad. Also any good places
    recommended for sending for repair (UK)?

    Many thanks in advance.

    One thing you can try is to clean the contacts on both the battery and
    its mating pins in the computer (if you can get to them). It sounds
    like intermittent contact somewhere.

    You might just get lucky.....

  3. Hi!

    It would be worthwhile to examine the power brick or the connector for it on
    the computer to see if either one has failed. It sounds like you're losing
    power input to the computer and it switches over to the battery as a result.
    If it were to happen enough, this could make charging the battery a very
    lengthy proposition. You might get lucky and find a bad line cord (most are
    detachable and therefore easily/cheaply replaced), frayed wire on the output
    side of the "brick" or a dirty connector.
