    Hi!!

    @Andoid

    As a work around, you can try doing Power Drain and BIOS reset. That might get back you the Bluetooth icon. 

    To execute it...

    1. Turn off the computer.
    2. Disconnect all cables including Power.
    3. Then press & hold power button for 20 seconds.
    4. Later reconnect all cables and power on the unit.
    5. When you power on, immediately start tap the DEL key.
    6. That should get into BIOS. Press F9 , Enter and F10, Enter.
    7. Computer will again restart. Check for Bluetooth icon.

    Hi @Andoid

    You can try to reinstall the bluetooth drivers to check if that makes any difference.

    Bluetooth Not Detecting Devices in Windows 11

    NOTE: After uninstalling the driver try to reboot the laptop to reinstall the uninstalled driver back to the computer.

    If in case it doesn't work then you can try to do a complete reset.

    https://support.microsoft.com/en-us/windows/recovery-options-in-windows-31ce2444-7de3-818c-d626-e3b5a3024da5#bkmk_win11_reset_pc

    Check the above link to do a complete reset.

    NOTE: Make sure to backup all the data before the reset.

    Hope it will help you in some way.

    It helps to look in Device Manager as suggested, but don't just look for the Bluetooth driver itself. The Bluetooth function actually look to the system like it's sitting behind an internal USB port, so if there is a driver issue with it the Bluetooth won't be visible at all, just as if the card was not installed.

    Hi,

    The Bluetooth adapter "Realtek Bluetooth... " is not there.

    If I try to reinstall the Bluetooth driver how can I tell which one as there appear to be two different drivers.

    Do you still have WiFi? Both WiFi and Bluetooth are on the same card internally so if one goes out usually the other does too. If WiFi is working fine and Bluetooth is showing as not installed then the issue is almost always in the USB connection managers or hubs.

    Yes, wifi is working fine, so how do I investigate further the USB connection manager or fix it?

    In Device Manager expand both of the USB sections at the bottom so we can see if there are any errors. A glitch there is what will make the Bluetooth invisible to the system.

    Yeah, if the driver is corrupted all manner of weird things can happen. Remove those two with the Device Descriptor failure then reboot and see if they fix themselves.

    I removed both and restarted, one of them returns and Bluetooth is still missing

    Try updating the drivers through windows update. Also install the drivers provided by OPTIONAL UPDATES.
