Is it possible to connect a bluetooth headset to a laptop?

I have a Motorola HS850 and the laptop is a Dell Latitude D400 with a
functioning BT module. I have no problem connecting my phone (Nokia
6820) to the laptop using BT and Nokia software to back up the data.
Also the headset works fine with the phone.

btw, the Dell is running "My Bluetooth Places 3.0.1.804" c. Widcomm.
The hardware is Dell Truemobile Bluetooth Module with the same version
number.

Thanks for any leads.
