When mine starting acting funny two days ago, the first thing I looked at was if the little receiver in the usb port was loose?....nope. The next thing...are the batteries going dead?
I took the cover off and was surprised to see two AA batteries side by side with both laying the same way. (+ to + and - to -
I didn't think they normally do that..and someone might have reversed one as a prank.
I switched one of them end for end and the mouse wouldn't work at all.
