Bluetooth Gone
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.

Apparently Dell cleverly removed my solution and turned it into a circular reference between two different threads.
The solution which worked for me was to do a system recovery and then disable the last several updates which Win10 had done. I can't remember the specific number. However... Doing the System Recovery was very difficult. Here are notes I took on how to make it work:
System Recover in Win 10:
System Restore done the normal way has never worked for me in Win 10. It always spins the wheels, then finally reports failure. i.e. Search for Restore, open up the Control Panel Recovery option, etc. However...
In thrashing around for a solution over the past week I did stumble onto a different way to run Restore that worked for me. It did break my Bitdefender, but that was easy enough to uninstall/reinstall then all was well. To invoke Restore I followed this path:
Click on Power > Shift-Restart > Troubleshoot > AdvancedOptions > SystemRestore. (system p/w when requested)

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?

A little detail would be so helpful for those (like me) coming up behind you and encountering the same issue. Hoping for a good Samaritan out there as my warranty just ran out. Thanks!
Hi Pierre
For me, the problem was a bad network card on the motherboard and fortunately, mine was still under warrantee. I shipped it back to them, and the job of course isn't the easiest because these are fixed units, not really meant to be opened up again (risks damage to the shell and associated clips). The removed the old card and replaced it with one that works (for now
You have two approaches that I can see - The first is to do the work yourself (there is likely a video on YouTube that will walk you through it).
Better choice - buy a $9 USB Bluetooth adapter and pop it in. That worked fine on my dell whilst I was trouble-shooting.
Best of luck,
tom

I found the related link that got me through this.
I did a complete shutdown, unplugged the power supply for 5 minutes, then powered back on. I had previously updated the Bluetooth driver from the Dell support site, which went smoothly.
BTW, my laptop is an Inspiron 13 7000 series.
Nice to see the great collaboration! Stay Safe!
This is the same thing that happened to me when my Alexa was not working, I turn off Bluetooth and restart my machine, and bang, Bluetooth was gone.

I resolved this on my own.
