  3. Device Manager Un-Hiding Hidden Devices


    When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

    The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

    Device can be disconnected when
    • Device unplugged (e.g. removing a USB device)
    • Turning a device OFF
    • Disabling the device in BIOS (then windows won't detect it) or
    • Device failure

    So
    • Check BIOS as suggested
    • Check board connections
    • Can b/t be turned off by a switch? or keyboard combination?
    Also possible the b/t h/w failed

    Network devices listed under Unknown in Device Manager


    I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.
