I have put new batteries in my wireless mouse and the lights are on however, it still does not work. I also have a wireless keyboard that I have not checked would that make the mouse not work?
Wireless devices come with a USB adapter that plugs into a USB slot on your pc. On the underside of the adapter there must be a little button that you can press. Once pressed, your adapter will start looking for wireless signals that are being transmitted by wireless devices. Now, look at the underside of your wireless device as there must be a “connect” button there as well. After the “connect” button is pressed on the wireless device it will begin to send indicators wirelessly to the USB adapter letting it know that it is there, and ready to be connected.
