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 port on your pc. On the lower of the adapter there must be a little button that you can press. Once pressed, your adapter begins looking for wireless indicators 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 signals wirelessly to the USB adapter letting it know that it’s there, and ready to be connected.
