XPS M1330, Bluetooth, Windows 7

I just upgraded the XPS from Vista to W 7 and found that the BLUETOOTH icon dissapear (the one that allow to do BT "on-off". Look unter hide icon, etc, nothing.

When I tried to dowload the s/w driver from BROADCOM, got a message to : TURN ON BLUETOOTH ADAPTER. Where ??

I restart the machine, F12 and in the BIOS is shown Bluetooth ENABLE.

In CONTROL PANEL, under DEVICES, there is a list of printers, usb, camera, etc., but no BLUETOOTH device.

Any help ? Suggestion ?

Is there any troubleshooting test to verify if the Bluetooth Adpater H/W is still alive ?

Thanks,
