  1. Bluetooth disappeared in the middle of call, on/off button gone, Code 45 in device manager


    Don't understand how this happened, but just randomly in the middle of a video call, my Bluetooth annihilated itself out of existence to the point where my computer thinks that I don't have Bluetooth capabilities. Through a series of forums I've found that every suggestion failed, the only thing left to do is uninstall the Bluetooth driver from my computer. Unfortunately, on the website for my computer where I need to re-download the drivers - it doesn't have an option for my computer. MSI Intel i5 9th Gen Leopard GL series GL65 95D Laptop - not sure what to do here. I also tried to use thei

    Turned off bluetooth, now the button is gone.

    I bought a Bluetooth dongle (ZEXMTE), worked as I needed, but then I turn off Bluetooth under devices, and now I cannot get it to turn back on.

    Ive ran the troubleshooter
    The device shows up under device manager (when I unplug and plug it in, it plays the noise but doesnt flash anymore)
    Ive tried reinstalling the driver
    Made sure Bluetooth services are running

    Also tried these steps:
    No button for bluetooth in action center - Windows 10 Forums
    blutooth not turning on in Windows 10 - Microsoft Community

    So I went into the device manager, right clicked, uninstalled the device. When I plugged it back it in, voila its working again.
