    Hey same owner same problem here.
    I'm using travelmate 4001 (it is btw a 4000 series) with radeon 9700.

    I have the same issue, one unknown device and the missing battery driver (so no battery status).

    And before another person posts some "helpful" suggestions.. And no, I did not turn off system icons in the system tray, did not disable any battery driver. Unplug and plugggins in battery do not work in this issue. THE PROBLEM is we need a driver for the battery/UPS device.

    Anyone has an idea which updated models share the same battery or something that is on Vista/7? Maybe we can try those drivers. And if anyone knows if battery drivers usually in the chipset drivers for motherboard?
