number 1 should light up when you running through wireless 2.4GHz dongle
try pressing that buton below 1 2 3 leds so it switches to "1"
also make sure that dongle works, open device manager and see if no driver errors
if all fine there, then check manuals, your mouse might need to be re-paired with that dongle
