After upgrading my wife’s Dell Inspiron 1525 to Windows 7 this weekend, I discovered that the Bluetooth had stopped working. Downloading the driver from the Dell site did nothing, which was not too surprising considering that nothing was showing up in Device Manager.
After a little googling, I managed to stumble upon the solution in a Dell support article. Turns out if the Bluetooth is off during an upgrade, you need to run a small application to re-enable it. I ran the download (only 153KB) and Windows 7 found the Bluetooth and installed it automatically within a couple of seconds. Since I have the RTM earlier than most, I thought I’d share this info in case others have the same problem.
