it should be plug and play.
most wirless devices like that have to be trained to the base station.
if you look on the base station you should see a button and the same on the base of the mouse.
plug the mouse in the laptop. then push the training button on the base station then the one on your mouse.
i could only find one driver software listed but i am not sure if this is for your mosue or not as you did not list its model number.
