Bluetooth disappeared

[Owl232]

Problem: Bluetooth has quit working. Have used it many times before; it stopped working one day for no apparent reason. Bluetooth no longer appears in the action center.

My system: HP Spectre 13-v011dx, Windows 10 64-bit. BIOS version: Insyde F.34, 6/15/2017.

Other info:

- Bluetooth also no longer appears in Device Manager.

- However, under "Universal serial bus controllers," there appears an "Unknown USB Device (Device Descriptor Request Failed)". It had a triangle with an exclamation point, so I disabled it.

- It's possible to make the bluetooth briefly reappear: I uninstall the Unknown USB Device from device manager, restart the computer, go into BIOS, reload factory defaults, save and exit. When it starts up, Device Manager and Action Center will both show bluetooth. But then the bluetooth will disappear within a minute, and the Unknown USB Device will reappear.

Solutions?

Have been seeing a lot of BT issues. MS had issued a patch on March 5 that fixed it for some. Third one in the list. Also check to be sure that usb device is not still disabled before trying this.

If the MS patch doesn't work-try this from Intel:

1. Download and save  latest set of drivers and software for your adapter:
    1. Wireless: WiFi_20.10.2_PROSet64_Win10.exe
    2. Bluetooth®: BT_20.0.0_64_Win10.exe
2. Under Programs and Features in the Control Panel, uninstall any instance of the "Intel® PROSet/Wireless Software" and "Intel® Wireless Bluetooth®." When prompted, choose to "discard settings."
3. Uninstall your device drivers from Device Manager:
    1. Network Adapters > Right click on your Intel(R) Dual Band Wireless and uninstall it. Make sure to select the option to "Delete the driver software for this device."
    2. Bluetooth® > Right click on your Intel(R) Wireless Bluetooth(R) and uninstall it. Make sure to select the option to "Delete the driver software for this device" if allowed.
4. Clear out your temporary files: Press the Windows* Key + R to open the run box. Type Cleanmgr.exe and press OK. Here you will need to make sure Temporary Files are checked, you may uncheck everything else then press OK.
5. Install the Intel® Wireless and Bluetooth® packages that you downloaded back in step one.
6. Reboot your system.

I had the same problem for a long time and I just found this post. Followed your method and I really workded! Thank you so much!

Brilliant, thanks! After rolling back the driver and also trying a driver update (Windowes said it was the latests version, it wasn't) it worked intermittently and the bluetooth icon etc. disappeared again after a restart. Your method worked perfectly and immediately without a reboot!

You can also go to the control panel 

Click on Uninstall program

Search for Intel(R) Wireless Bluetooth(R)

Right-click on it and select repair

This re-downloads the drivers without changing it back to default so you still get to maintain your same bluetooth name and already connected devices.

Thank you!
