Bluetooth Driver Crashes, Gets Disabled Forever on XPS 15 9550

Do you have any other Bluetooth devices or can you run you system without that mouse for testing?

What model is the mouse?

There was a Windows update yesterday, has that been done?

New Windows Build coming next week, which might also effect the situation.

Like I mentioned, all  Windows Updates have been applied, latest drivers verified as well. I'm in the tech industry, so these handling the usual diagnostics is commonplace for me. What I don't understand is how the Bluetooth itself can disappear. Checked the Windows Update history, no updates were applied today.

I could make do with another mouse for now. If you're asking whether I could use other Bluetooth devices which are paired with this machine, unfortunately no, not at all. The laptop currently works like there's no Bluetooth chip or driver in it at all. Prior to this, I managed to bring it back alive by applying the latest BIOS from Dell.

And I did further digging in Event Viewer to see if I can find anything, nope. No Errors or Warnings for today in Hardware, System or Applications.

The reason the device may disappear is because it is not being picked up during boot so the device is not being recognized.  A conflict of some kind with a device might be causing that device to be rejected.

In device manager you can check the properties of the BlueTooth radio and look for an events tab.  In some cases, it will show what is happening with the device.  Make sure and scroll the window if needed.  If it shows the driver being reinstalled over and over, it is having problems.

I asked about the mouse in case it was causing a conflict.  Several years ago, my experience with Bluetooth mice was not good.  Recently, it has improved but I have not tried my older one with the new Win 10 builds.

I have one system on which I installed a Kiler Wireless 1535 for testing.  So far, I am happy with it. (I think I have the model number correct)  I run several Bluetooth devices, such as headsets, external speakers.  If I can find my old mouse, I will try it also.

You might check the hidden devices view and see if it shows up there, but if it is just greyed out that means it is not connected.  And no, you cannot do anything with a device which is not shown in device manager.

The Killer Wireless Adapter seems to be working and since the Bluetooth is on the same card, it is installed.  

You have one USB device showing as unknown, so maybe correcting that situation would help.

Since it was already going in and out, it is probably already enabled in the Bios.  You might try disabling the Bluetooth in the Bios and rebooting a couple of times and then re-enable it.

I also mentioned that I did checked for Bluetooth in Device Manager in case you missed it. Do you see Bluetooth in my Device Manager? This was what I meant, Bluetooth no longer exist in Device Manager. When it works I could come here and make changes or whatever, now it disappeared.

I am trying to solve the same issue with a brand new XPS 13.  On the line now with Dell Support.  

I've had a similar problem for almost a year.  Many times I lose BT after a reboot.  I have to un-install the BT device then scan for hardware changes. Then all is good for a while.

I'm using a Microsoft mouse.  I have not applie any bios or driver updates because I'm afraid of getting the screen flicker back again.

I'm having the exact same issue with a recently purchased XPS 15 9560.  Suddenly, NO ENTRY in device manager for Bluetooth at all (and seemingly no way to install/restore it)

What worked for me was to reinstall the latest BIOS file for my machine.  We shall see if that fix endures...

updated bios to 14.  didn't resolve my issue.

I've had a lot of problems with my XPS 15" 9560. Dell wanted me to reinstall Windows, simple for them to say. It's done once, but I'm not doing it again. It's something wrong with DELL's support organization that does not fix it.

"Google" has a lot of disappointed users of 9560. How can it continue?

Have you got any solution to your problem? I updated the BIOS today and after that I have been unable to use my wireless mouse on my new DELL. On my 5 year old ASUS, the same mouse works perfectly. And on my MacBook Pro.

I have tried a lot, two hours. Install and uninstall drivers. Shut of and on in BIOS. Nothing helpes. This time is worse than ever. The previous times it has suddenly start to working.

Open question. Is there no solution to this? It *** really ....

What  Wi-Fi adapter do you have on your system?

If you look in Device Manager and the Bluetooth properties, there is an Events tab.  Could you give us some insight into what it might be showing.  Notice the scroll bar and the dialog at the bottom depends on which entry you selected.
