HP Pavilion battery charge circuit defective

  1. Default HP Pavilion battery charge circuit defective

    I have an HP Pavilion ZT1135 notebook computer running Windows XP Home
    Edition. The unit is about 30 months old.

    A few weeks ago the charge state with the original battery began showing a
    charge state of 84% all the time, even after several hours of attempted
    charging. However, the battery apparently was not getting charged because
    the computer
    would not turn on unless the power supply was plugged in. That is, the
    computer could not run in battery-only mode.

    I replaced the battery, but the computer still would not run unless the
    power supply is plugged in. With the new battery, the charge state always
    indicates 0%, even after several hours of attempted charging. Thus, for this
    new battery as well as the original one, the computer cannot run in
    battery-only mode.

    Then, thinking that the power supply unit was somehow defective, I tried a
    new power supply unit. Nothing changed. Neither battery would charge.

    Finally, I tried resetting the power management function (turning off the
    computer, holding the power switch down for 1 minute, turning the computer
    on, going into the control panel power management function and checking the
    status), and all looks normal, but neither the old battery nor the new one
    will allow the computer to run in battery-only mode - even after several
    hours of charging.

    So I contacted HP. All they would tell me was that it is probably a bad
    battery charging circuit inside the computer. Getting the notebook repaired,
    according to HP, would be in excess of $500.

    Then I looked up a few forums on the internet. I was amazed at the number of
    battery-charging complaints similar to mine, and not just about HP
    notebooks, but others as well, including Gateway and IBM. From what I read
    in these forums, battery charging circuitry failure is fairly common with
    many notebook brands.

    Any comments, suggestions, and especially problem solutions are most
    welcome.

    I've already decided that HP will not be one of my future purchases

    Ok, you youve got a notebook, that has problems that plague every
    company, and based on that you wont buy HP?


    And for the record, that repair will be $649 plus tax, and would still
    be covered had you bought an extended warranty either through HP, or
    the store you bought it from (3 years is 36 months)
