I recently upgraded to Windows 7 Ultimate from Home Premium on my G73jh. All seems to be well except the Bluetooth function. I get no indication of any Bluetooth function at all when I boot up. Through lots of trial and error, re-installing drivers, etc., I figured out that once it boots up I have to use Fn/F2 to turn on the WLAN, then use Fn/F1 to put the thing to sleep. Then I wake it up and the Bluetooth works fine. I have another HDD with Windows 8 on it that I have been playing with which is a whole other story, but Bluetooth works fine on that one so I know the hardware part works.
This probably has something to do with it as well; when I use Fn/F2 to turn on the WLAN, there is an icon there to turn the Bluetooth on and off and it shows it as off. If I could figure out how to turn this icon on, it would probably cure the problem.
So, why do I have to put my laptop down for a short nap in order to get the Bluetooth to work?
