Hi Acid, my Pavilion DV6-6114TX was operating without too much problems for 2 and a half years plus and just recently I discovered my Bluetooth cannot work when I tried to send a file popping up an error stating that "Bluetooth device not found".

Besides that I also noticed that the icon had gone missing from my taskbar. So I pressed customize taskbar and the Bluetooth icon is not there either.
Apart from that, Besides "Bluetooth Devices" missing in the control panel's "Devices & Printers" which was eventually there before I noticed this problem, I also noticed when I press the wireless sign on my keyboard to switch off all wireless, then after that I switch it back on, there is a message showing "USB Device Not Recognized". I suspect it is somehow related to the Bluetooth as I know switching off the wireless on the keyboard shuts Bluetooth and WiFi off together.

Besides that there is also a yellow waning sign in my device manager which was the unrecognised USB device mentioned earlier.

Plus, as you can see in the photo below, there is no signs of any Bluetooth adapter found in my computer.

Apart from those I also noticed that the "Bluetooth Devices" icon and settings is also missing in my control panel's "Hardware & Sound" & also "Network Connections". They were there before I noticed this problem.

So I tried to reinstall the Broadcom 2070 Bluetooth driver (Version: 6.2.0.6300) from "HP Recovery Manager" but it didn't seemed to work. However, when I searched for Bluetooth in the "Start" search bar, the program is still there, so when I open the file location and pressed on the program no respond at all.

So, do you have any idea could this be a hardware problem or a software problem or most probably something wrong with the driver? Your advice is kindly appreciated. Looking forward to your reply. Thank You.
