I have an Inspiron 5493 just a few weeks old. Microsoft updated Windows 10 Home last evening and my Bluetooth mouse quit working. Going into Bluetooth settings I see that the button to turn it off/on no longer exists even and I cannot pair the mouse.
So I checked the Bluetooth Troubleshooter which informs me that I have no Bluetooth adapter. Hmm...
So I did uninstall all but one of the Windows updates but no help. The last update is a security update which will not allow itself to be uninstalled.
Finally I uninstalled the QCA9377 Bluetooth driver and reinstalled the driver downloaded from Dell this morning. It installed with no complaints, but Windows still says the computer still has no Bluetooth adapter.
Any idea how to resolve this problem? Thanks.
P.S. One other anomaly exists which I have no idea if it's related or not. In the Device Manager it shows an "Unknown USB Device". I've tried to update it, but Win says it's already at the current level. I also tried deleting and reinstalling it. Also have tried turning power off for a minute or two before rebooting with no change.
Solved! Go to Solution.
I received a private message about this which asks for some info I'd think Dell already has just from my Service Code which I did give them. From Dell-Cares.
How do I tell if this is legitimate or a scam?
