Enabling Bluetooth On Asus Notebook

I'm New OS : Vista

Hi i recently purchased a asus pro50G laptop (or f5gl) and it says it has bluetooth, as well as a bluetooth light next to power and wireless etc. But i cannot use bluetooth on the device, and cannot find any drivers whatsoever formy machine and if i find ones remotely fitting on the asus website i try to install them and it saus i need to plug in a bluetooth device.
Does anyone have any idea how to get this to work i've tried everything.
And no the driver is not on the installation cd.
