Windows 10: option to turn on bluetooth is gone

My bluetooth has always worked fine, today when I tried to connect my airpods it wouldn't let me because "bluetooth is off." Then I noticed the option to turn it ON is missing. I ran the troubleshooter and it said "Bluetooth is not available on this device. Please try using an external adapter." but I KNOW that bluetooth is built in because it was working just FINE yesterday. I even tried going to device manager and I couldn't find bluetooth anywhere.

:)

 

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.

 

Turn On or Off Bluetooth in Windows 10  

Yes, Shawn, but only insofar as immediate effect (the button became unlit and the text on it greyed out). After making that observation, without re-enabling Bluetooth in device manager, I rebooted. Upon reboot, I find that:

• The Bluetooth button in Action center is once again lit,
• but "Bluetooth" is gone from the Devices menu, and
• Right clicking Bluetooth in Device Manager, presents "Enable" as an option (implying it is indeed disabled).

 

I don't have any bluetooth devices but windows turned it on!!


Then if they are still on, try some of these steps listed below, Not all of these steps may not apply, but, step #2 and #4 should help. I have all 4 steps on myself.

1 Go to Device manager and DISABLE Bluetooth, Do Not remove!
2 Turn USB suspend off
3 Set Hard Drive or SSD to Never
4 Turn Link State Power Management off
Settings 2 thur 4 can be found in your Power Management Settings.
Then click on "Change settings that are currently unavailable"
Then Reboot your Computer. This does work, may come back if you shut OFF your computer,then turn it back on, if it does, just a reboot will turn it off again.
