Starting yesterday and in the middle of work (not after a specific update), I noticed that my Bluetooth keyboard stopped working. And then saw that Bluetooth is turned off.

So, I tried a few restarts to no avail.

Here is a list of other measures I have taken:

  • Windows Update and all the driver updates
  • Dell Update of all the drivers' Scan Device Manager for any hardware changes
  • Starting all 3 Bluetooth-related services on Services

Each measure was followed by a restart.

But despite all, I am unable to turn Bluetooth on. There is no toggle button appearing on Bluetooth and other devices settings on my Windows.

I have several Bluetooth devices. So, this is not only about the keyboard. None of the connected Bluetooth devices are working.

Bluetooth does not appear in Action Center, either.

OS: Microsoft Windows 10 Pro, 10.0.19042 Build 19042

Laptop: Dell XPS 13 9380

UPDATE 1: This is the result of my Bluetooth troubleshooting.

Device does not have Bluetooth

Bluetooth is not available on this device. Please try using an external adapter to add Bluetooth capability to this computer

UPDATE 2: View of Bluetooth devices in Device Manager

  • Check programs and features list for Bluetooth software, if it is there, uninstall it, let windows update reinstall it.

  • Check if there is any unknown USB device under USB in Device manager, if yes, please try to disable it and then enable.

  • There is one unknown USB device called Unknown USB Device (Device Descriptor Request Failed). I have tried disabling it, updating its driver (there is no new update), and uninstalling it (it pops back up when scanning for hardware changes). I'm not sure if this is the Bluetooth driver. Is there any way of knowing?

  • Check the Bluetooth hardware in device manager... Is it functioning?

I had this exact same problem with Windows 10. I have a Asus BT-500 Bluetooth adapter. I downloaded and installed the software package from Asus rebooted and it worked for a few weeks.

All of a sudden windows wouldn't recognize the adapter nor launch the service as it listed as "Bluetooth is turned off" in settings with no slider available to turn it back on. Although the correct drivers were installed & it had worked previously was I stumped.

My solution was to:

  1. Press ⊞ Win+R - enter Services.msc and double check that all bluetooth services are running and set to automatic.

  2. I did not fall back to a system restore. I opened device manager and found my device under the USB heading instead of a bluetooth category.

  3. I clicked properties then update driver and chose my exact driver software installation folder from the manufacturer - pointing to the appropriate sub- folder of the bluetooth installation driver software package.

    (Although it was technically already installed and sure enough it "re- installed" my USB dongle and all bluetooth devices immediately)

Hopefully this helps.
