Over the past few months.. my logitech laser mouse (one of the originals, i cant remember what its called) has been making a strange electronic sound like an old dial up modem only rather silent until you put it up to your ear. i noticed one day while replacing batteries. i dropped a battery in my pack and heard the mouse makin noises. Is this normal for your wireless laser mice? Pick it up and listen from the bottom of the mouse and tell me.. i think its the logitech mx 3000 set up.
lol you must have supernatural hearing because you can hear the wireless signal coming from your mouse :O
