The new graphics driver and associated chipset audio driver installed without problem. HDMI audio works and I don't need the F8 trick to get 1920x1080. Much better!
I still don't get Bluetooth. The new diver installs without problem, But, there is no Bluetooth device in the Network adapters section of Device Manager and the Bluetooth control icon does not show up on the task bar. It behave just like a laptop which has the Bluetooth device powered off.
Two notes:
1. The new driver identifies itself as "Intel (R) PROSet/Wireless Software for Bluetooth(R) Technology(patch version 3.0.1342.2)". That's not consistent with the file name of the driver installer (BT_Win7_64_3.1.1311.exe).
2. I have an unidentified (Unknown Device) USB Controller under other devices in Device Manager. The error I get at startup is "USB Device not recognized". The "Unknown Device" is on the 4th port of a "Generic USB Hub (4 ports)" which is in turn connected to the first port of a "USB Root Hub (8 ports) ". Interestingly, if I remove the Intel Bluetooth software, the startup error message goes away (but, the Unknown device is still visible in Device Manager.)
