Having problem with my wireless mouse: not responding to


Dec 2, 2014
First off, I'm not up on my tech jargon, sorry and things I should know the name of , well, I don't..My wireless mouse has just started going erratic:the arrow shows up on the screen but it will not consistently move in the direction I push it and sometimes it goes in the opposite direction. Other times it is simply stopped, 'lurking' on the outside of the screen and isn't responsive at to moving back into it. Also I recently noticed that the light sensor on the bottom of the mouse is not steady but sort of flashing rapidly. Is this a battery going dead? I tried the mouse on another port on my computer and on another whole PC. Same result.
Could you please advise me about this?
