Hi Kunal,
Please share if you have tried performing the troubleshooting steps that I recommended in my original post. The issue may be related to 'Bluetooth' as you said; however the steps I recommended will isolate that possibility.
To help you with the installation of 'Bluetooth drivers', I need to know your system details to help you further. Please share the following details:
- The link of the Bluetooth driver on 'Dell Support website' that you tried installing
- Please share the operating system installed in the computer (Windows 7/8 and the make 32/64 bit)
- Please share the screenshot of 'Device Manager' in your computer (You may refer to the steps listed below)
- 'Right click 'Computer', click 'Manage' and click 'Device Manager' to access the 'Device Manager' page
- Locate and expand category 'Bluetooth Radios'; If not listed under 'Bluetooth Radios', please expand 'Network Adapters' category
- Please capture the details of 'Bluetooth Card' installed in the system (Note if any yellow/exclamation mark' is present besides it)
Hope this helps. Do reply if you have any further questions. I would be glad to assist.
