Hi all,

My PC has been working fine before, but decided to act up today. Out of a sudden, my bluetooth is turned off, and there is no option to turn it back on. I tried reinstalling the drivers, remove, and repair, but it did not help. 

The Bluetooth Adapter is still not showing up in my Device Manager, even when I select to show Hidden Devices.

Now I am stuck, unable to connect to my speakers, controllers, and keyboard. Gotta quickly find a wired keyboard just to type this. On a side note, WiFi is working fine too.

Mainboard is a Gigabyte Aorus B550i, installed both bluetooth drivers from Gigabyte and from Intel, didn't help. Bluetooth adapter is an Intel Wi-Fi 6 AX200.

Please help :(

    I don't think reverting to an older will help.  I tried that myself.

    Shut down the computer normally.  When the lights and fans are off remove the power cord at the back. wait 30 seconds and turn on the computer.  It should rediscover your bluetooth and it should work now.  

    If that fails tell Gigabyte to FEDEX you a new motherboard and explain the problem to them.  They may be having severe COV-19 issues.  They never answered my Phone calls or emails. Good Luck.

    They will fix it be patient and do'n stop bugging them.

    See the explanations above about power down / drain power / power up .. that will temporarily restore the device.

    For a longer term solution, you probably need to revert to the F2 BIOS (I am using F4 which also seems ok).

    For a longer, longer term solution we all need to 'kick' Gigabyte and/or Intel :)

    Same motherboard as you LOL...yea I had this nightmare and don't really know what broke it! 

    Try getting the F2 BIOS and reflashing your BIOS if you haven't tried already of maybe your already on the F2 BIOS I don't know. 

    B550I AORUS PRO AX (rev. 1.0) mITX Motherboard BIOS Version F2

    Web address here if the web link above doesn't work ---> 

    https://www.gigabyte.com/Motherboard/B550I-AORUS-PRO-AX-rev-10/support#support-dl-bios

    I'm taking it into account you know how to flash your BIOS? If not just grab that file, extract it to your Downloads Folder or wherever and copy the contents or most importantly at least the B55IAPAX.F2 file as that's the one you need.

    Reboot and enter your BIOS (Tap Del (Delete Key) and enter QFlash...save your current BIOS if you want...otherwise select the drive where your F2 is and flash. 

    After that's done...and rebooted...try turning of PC...unplugging the power cord...tap the power button to drain the PC of all static power...Plug in and reattempt to enable the device in System Properties if it hasn't already found it!

    Hi ..

    Try the power down and unplug approach (I also try to turn the PC on while powered down). This seems to bring the Bluetooth device back and everything will work again for a while.

    Reinstalling drivers, OS etc does not seem to fix this issue.

    I have reverted to the F4 BIOS and have not had the issue for over two weeks now. This one ...

    Other than that the only other solution seems to be to purchase a cheap UDB Bluetooth dongle (not ideal).

    I have not tried the very latest BIOS so don't know if that will fix things or not.
