it used to work but i dont know what happend , now i can see the bluelight for the bluetooth only when booting , then it dissapears .
also i couldnt find in device manager its all gone !
i tried to install the original buetooth drivers from the link up < but it keep saying that it didnt detect any bluetooth devices
, by the way when i first got the lab i formated it compeltely form win vista . and installed win 7 ultimate without saving ANY drivers !
