    unknown device in device manager


    Hey guys , I thought I might ask here as I don't seems to be getting a solution on Dells forum .

    Unknown device ACPI\CPL0002\2&DABA3FF&0 is showing up with a clean install of windows 10 pro on a dell alienware 13 ,2015 model .

    Any ideas what this is ? Everything is working fine but like a lot of us here we want to see a clean device manager .

    Thanks in advance

    Hi, perhaps see:
    Unknown Device under Device Manager m11xR3 | Alienware Arena

    Unknown device - need help. | Page 3 | NotebookReview

    Older threads... may be a free-fall sensor.

    Question is, how is that supported in Win 10?
    If for example Dell only supports this to Win 8, you could try the appropriate Win 8 driver.

    Another approach that I have only used 'in extremis' is to use, say, Drivermax (free for 2 drivers a day). This solved a missing driver problem on an HP laptop for me.

    I got the same issue but with Vista yesterday. I clean installed Vista 32 bit and when I saw under Device Manager, I saw an Unknown device. I right clicked on it and let Windows search for the driver and it applied the driver and voila, I no longer saw that anymore.

    You could try running the chipset inf install again.

    ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption in desktop and mobile computers. ACPI specifies how a computer's basic input/output system, operating system, and peripheral devices communicate with each other about power usage.
    You may not need it at all, your BIOS will probably handle it fine.

    Could be anything really it seems.

    What does the value for the Hardware Ids property say on the device details pane above? Perhaps that is more specific than the Device instance path shown...

    May be worth looking here Unable to install driver - Microsoft Community

    Looking like it may well be Alienware On Screen Display driver
