    I can't start the "Uninterruptible Power Supply" service in XP Pro
    sp2; I get:
    "Could not start the Uninterruptible Power Supply service on Local
    Computer. Error 2481: The UPS service is not configured correctly."

    (I'm trying to start this service so the UPS tab will display in Power
    Options so I can get my laptop to communicate with my APC Smart-UPS v/
    s 650 on COM4 via a Keyspan USB Serial Adaptor.)

    Do you have a COM4?

    Start | Run <type in>
    Under Ports.

    If not you need to add one by using the Control panel / Add new

    Possible solution found

    I think I have fixed this problem.

    This problem appeared on a server that I admin.

    Previously, I had used a UPS connected to a COM port, and am sure the UPS service was functioning. After replacing the UPS and using the USB connection is most likely where the problem began.

    Because the configuration for the COM port UPS was never erased, when the HID-Battery device was installed, I'm sure the UPS tab was disabled and the service was disabled, but the configuration was still set up for the old UPS. I noticed this under the UPS Service settings in the registry. The easiest way to erase those settings and configure them for default is to simply select (None) from the "Select..." section of the UPS tab.

    Since the UPS tab somehow disappeared, we need to get that back first.
    There is a simple registry key entry to add to make this tab show again.


    Value Name: ShowUPSTab
    Data Type : REG_DWORD
    Data Value: 1

    Once you have modified the registry with this value, re-open the power control panel, press "Select...", and choose (None)

    You may have to select a random UPS and apply those settings if (None) is already selected, then change back to (None) and apply again.

    This should default your UPS configuration.

    Thanks, that worked! The UPS tab is back, at the minimum.
