Bluetooth missing from device manager

[Jugal_Padhan]

Hi

The bluetooth device suddenly dissapeared from device manager and I can't find a way to solve this problem. This happened while I was using Windows 10. I did a factory reset to windows 8.1 and still the problem remains unsolved.Also  one of the USB contollers is not working (showing a yellow caution symbol). A code 43 error is displayed when i check the properties of this unknown USB device. Here's a screenshot of my device manager. Please help!

Hi @Jugal_Padhan,

Thanks for visiting the HP community. A very good day to you!  I read the post regarding Bluetooth issues with the computer. I will be delighted to assist you here. 

You’ve done an excellent job on diagnosing the issue from your end. Superb effort and great diagnosis were done as well.  Kudos to you on that score. . I take it as a privilege to share this platform with you. 

For better clarity and to assist you better, I would require more information regarding this:

• Did you check by pairing multiple devices to your computer via Bluetooth?
• Has your Bluetooth feature stopped working completely and when did it last work?

It could be a hardware issue with the Bluetooth device.

The Bluetooth feature and the wireless feature of your computer is on a single combo card.

Please check the product specs from this link: https://support.hp.com/us-en/product/hp-pavilion-15-p000-notebook-pc-series/6936226/model/7280165/do...

For now please try these steps:

• Please perform all the required steps from this link:  HP PCs - Using Bluetooth Devices (Windows 10, 😎 to troubleshoot Bluetooth issues.
• Also update the bios, chipset and wireless drivers from this link:  http://hp.care/2s4KpRN
• Please check this link out for further assistance: HP PCs - Understanding and troubleshooting Bluetooth wireless technology (Windows 8.1, 8, 7, Vista, ...

• HP PCs - Device Manager Information (Windows 10, 😎

• If it still does not work, then the Bluetooth module is faulty. You could buy a USB Bluetooth dongle from a local store like Best Buy or Staples or through an online portal like Amazon or Ebay.
• It is very cost effective and economical. All you need to do is plug it into one of the USB ports of the computer and pair it with any Bluetooth device that you have.

  Please perform all these steps patiently as it is very critical to resolving the issue.

Hope this helps. Let me know how this goes. I hope the issue gets resolved without hassles and the unit works great. I'm always there to assist you. Please reach out anytime.

Cheers!

I installed the Broadcom bluetooth driver. Now it worked for sometime and when i restarted the pc,there was no bluetooth. This availability of bluetooth in device manager is random. Sometime it is there and sometimes not.

Also this has been affecting the functionality of my wifi driver. Turning on and off the wifi manually doesn't work sometimes.I have to restart the pc for it to work again.

I think the wireless card is faulty or some other problem in motherboard.

I had the same thing happen just now on my Spectre 13"  X360.  Missing Bluetooth and error with an "unidentifiable" USB device.  After following the advice to update/re-install the various drivers for chipset, WLAN, BT, and updated my BIOS, nothing had changed. 

I then simply uninstalled the bad unidentifiable USB device, rebooted, and voila: my Bluetooth device was back!  Now it seems to work OK.  No errors with USB devices. 

I'm suspecting heat.  This laptop can get very warm almost hot at times...

I take it back!  The BT device went away again, and is showing up as a bad USB device.   It must be a defective card.  Good thing I bought extended warranty.  Hope they can fix it.

I have tried to do the above and it did not resolve my issue.

It's been a while since this problem showed, up, went away and came back - however, I did fix it.  It turned out to be the Windows driver for the Intel chipset didn't work.  I uninstalled that and got the correct driver directly from Intel.  That fixed the problem.  Not just on one Spectre X360, but also the one my wife uses.  Although my machine had other problems, bad MOBO, that were corrected with warranty work, the BT was fixed with the proper drivers from Intel directly.  Hope this helps.
