For some reason the default Bluetooth driver that comes with Windows 7 and Vista doesn't have the "Turn Adapter On/Off" option, so you can't turn on the bluetooth...
To install the correct driver do the following:
R155395.exe
(Wirless 360 Module with Bluetooth) (Don't do the firmware
upgrade yet)bth.inf
and bth.pnf
from C:\Windows\inf
to a temporary locationbth.inf
and bth.pnf
back in C:\Windows\inf
(otherwise it won't
install the driver)C:\Dell\drivers\R155395\Drivers
R155395.exe
again) and this time
do the firmware upgrade.
