Waiting this long may mean you have to restore the machine to it's factory condition. It's a shame you didn't use system restore which it first failed.
I have been using a HP DV3 Pavillion Note Book for last year and a half, which has bluetooth connectivity. It runs on Windows7 Home Premium OS. For the last several months, my note book cannot connect to any other bluetooth device in its vicinity, nor other devices can connect to it. Even in the notification area bluetooth icon no longer appears. It is as if bluetooth software has simply disappeared. HP Wireless assistant shows that bluetooth has been disabled. The wireless assistant screen does not show any button to enable it. What could be the problem? How do I correct it? I would be grateful for any guidance from the CNET community.
