In a recent post I have talked about my experience with upgrading to Windows Vista on a Sony Vaio notebook.

While the overall upgrade process was smooth, still there were problems with some of the hardware. Sony's notebooks have many bells and whistles and therefore there are chances that something will be missing.

After using Windows Vista for a day, I noticed that the battery time has dramatically declined. Then I noticed that the Bluetooth indicator was on all the time. Further I noticed that I could not activate/de-activate Bluetooth. The same goes for the WWAN module. In other words, the I needed SmartWi for Windows Vista. After upgrading to Windows Vista Sony hardware buttons (for launching applications) are not functioning as well.

To address these issues, you can download all those drivers and utilities from this link: http://www.vaio-link.com/downloads/os/vista/upgrade.html.

Overall, Windows Vista rocks!
