UPS battery not detected

I'm running 64 bit Vista in a dual-boot setup (two seperate installations on a tower PC). I have a UPS connected to a USB port which up until now both Vista installations have been handling correctly.

One one installation the taskbar power icon has started to tell me "no battery is detected" - yet the Device Manager  shows the HID UPS Battery to be present and working. The taskbar icon was working perfectly well until today (the Vista installation was done a week ago).

The second Vista installation's taskbar icon is detecting the UPS battery correctly and reporting the correct level of charge.

Therefore the problem would appear to be Vista related rather than a hardware problem (if the UPS was faulty or the cable unplugged then both installations should indicate there's no battery connected...). Rebooting doesn't solve the problem, nor does uninstalling the UPS in Device Manager and allowing Vista to re-install it.

Any ideas?

    Well, first off, as I said, this is not a laptop. It's a tower (desktop) PC attached to an Uninterruptable Power Supply. So laptop-specific solutions aren't the answer. Nor is the problem likely to be hardware related as I have two Vista installations on this PC and one is affected and the other isn't. Thanks for the suggestions anyway.

    Secondly, both installations of Vista are using the same drivers, i.e. the MS ones that come with Vista. I've run this setup for a couple of years, with no problems at all on previous installations.

    Anyway, after 36 hours or so of not working, the power settings have once again decided to notice there is indeed a battery connected and start working properly again.

    I hate intermittent issues that appear from nowhere and then go away, but I guess I'll have to wait for the problem to come back (if it ever does) and have another go at fixing it then.

    Hi,

    ·          What is the make and model number of the computer?

    Step 1: You may perform a power cycle of the computer and check if it solves the issue.

    a.     Unplug all external devices from the laptop.

    b.     Take out the battery of the laptop.

    c.     Press the power button of the laptop for 10-15 seconds.

    d.     Insert the battery into the laptop and restart the computer.

    e.     Connect the AC adapter and check.

    Step 2: Also check in the manufacturer’s website to see if there are any updated drivers and install the same.
