Hi,

I have a Vostro 3591. My bluetooth driver just got disabled today. I can see it in the Device Manager when I enabled "Hidden Devices". I have tried the following:

1. Ran SupportAssist but I keep getting unknown error. I guess it's because my warranty has expired.

 

2. Installed all latest drivers that were recommended

 

3. Manually downloaded the Bluetooth driver and installed it.

 

4. Ran the Bluetooth troubleshooter.
