try it in another usb port, should then come to life
this might be a bit obvious but does it have an on off switch?
if yes, is it turned on?
the lazer does no light up underneath,uninstall drivers and then re-install don,t know what win you using but there is a win 7 driver out now for it,plus have you pressed the infra red button on the mouse so it can sync with the docking station,think thats your problem.
Out of interest now they've been out for a while how are the people that bought one of these beasties getting on.
I'm due a new mouse and tend to go for the ~£50 range for something reasonable but given the use it gets I could be persuaded to get a bit carried away if they are proving to be a good long term investment.
That and it fits my hand perfectly and is the first mouse with thumb buttons that are actually in a comfortable place.
Have you tested it wired?
