Problem Description:

Yesterday I updated my laptop's BIOS to F 5A - latest available on HP Website. Since then I have lost the bluetooth functionality, which was wroking just fine prior to the update. Now the system doesn't find a bluetooth device.

What I have already done:

1. Switched back to previous versions of BIOS (available on HP Website coz I didn't note the BIOS version before I updated it). - That didn't work.

2. Reseated the wireless card - Didn't work.

3. Manually checked the connection of bluetooth module to the motherboard - Connection was fine but it still didn't work.

4. Uninstalled the bluetooth driver and reinstalled it (HP integrated module WIDCOM) - still didn't work

5. Installed HP Wireless Agent - Didn't work

6. Installed HP Integrated module driver along with HP Wireless Agent - Didn't work

7. Installed Ubuntu to check if its recognizing the device - Even its not recognizing the device which it used to do earlier.

8. Sadly there's no BIOS setting in Setup which I can change to correct the bluetooth behaviour (Phoenix BIOS with limited interface).

After all the research, I am posting this because I am unable to find a sloution to this problem on my own. I request the members to please help.

I got the bluetooth working. Had to dismantle the laptop and found that a small switch was loose.
