I have a Dell Studio laptop 1537 Laptop... very good laptop I might add. However the bluetooth was not working. The software for Bluetooth was installed, Bluetooth was enabled in the BIOS however in windows Bluetooth would not appear in device manager. The laptop is running Vista Ultimate 32bit.
I also confirmed that BTTray.exe was running in the background however the bluetooth icon would never appear in the system tray.
I also had issues with the wireless button that controlls bluetooth and wifi. When you turn the wireless switch off bluetooth and wifi are ment to stay disabled. However if you close the laptop lid and put it to sleep then wake it up again, the wireless and bluetooth would re-enable even though the switch was still turned off. When I say bluetooth, I mean the bluetooth light on the laptop... the bluetooth in windows was still not functioning or getting detected in device manager.
The Dell Studio 1537 laptops come with a built in Dell Wireless 370 Bluetooth Mini-card.
I noticed that there was a bios revision. This notebook came with A07, and the update on Dell released febuary 2009 was A08. After installing this revision bluetooth showed up in device manager, the BTTray.exe icon appeared in my system tray. The Dell Bluetooth Travel mouse now works! Additionally this BIOS revision fixed the problems with the wireless button on the side of the laptop. Now when its off it stays off!
