Hi Nishantsinha,
I understand you are having issue with Bluetooth. The HP Wireless Assistant allows you to verify that a Bluetooth device is installed and to check the status of the wireless devices on the computer. To enable the Bluetooth device, do the following:
Click Windows key, enter HP Wireless Assistant. It should show you if it is on or off. Drivers for this device at located at this link.
Have you tried to uninstall and reinstall?
Hope this helps.
Thanks
