Win XP - forcing power management

  1. Is it possible to force Windows XP to treat a device as ACPI/APM/power maganement compatible?



    After I installed the drivers for my radio card (newest (year 2000 :grinthumb)), the
    XP disabled all suspend features. That's cool - I bet my radio
    doesn't have a clue about ACPI and Windows XP is user friendly and all ...
    but 98SE would happily suspend the computer leaving the radio play

    in the background...


    So, I know my radio card can survive suspend without crashing the machine
    (did so when running Win98 and also when no drivers were installed), can I make Windows XP think that
    this device can be suspended?

    From this time forward, you will service us.... - The Borg.

    As far as I am aware, no.

    I think drivers have to be written to be ACPI compatible.

    If your device isn't, I am not sure if you can do much about this apart from ask your hardware manufacturer to start producing hardware that is.

    I've certainly never heard of this. Anyone??

    Nope.
    Whoever developed the Drivers will have to fix it like Phantasm said.

    But it's the same driver that allows suspend under Win98, it's just WinXP that's uptight about ACPI compatibility...

    Same solution though. I mean, if you uninstall the device & it works fine then it has to be the driver.
