The Microsoft Wireless Optical Mouse 2.0A is a good alternative to a standard corded mouse. This wireless optical mouse is more versatile than traditional mice due to its wireless connection and that it doesn't require a mouse pad. As well, this mouse's plug-and-play capability does not require any software to be installed before use.
Separate and identify the mouse and the receiver. At this point, the mouse's LED should illuminate. If there is no light coming from the LED on the bottom of the mouse, you may need to change the batteries by pressing on the button marked with a star and opening the mouse casing to access the battery compartment.
Plug the receiver into an open USB port on your computer. Since the mouse functions wirelessly, the receiver will need to be connected to a working USB port that can provide power. Typically, your computer will make a noise to show it recognises the new device.
Press the connect buttons on both the underside of the mouse and on the receiver. Holding these buttons down for several seconds will refresh the wireless connection, which is good if the mouse becomes jumpy or erratic. The connect button will complete the connection and allow you to use your new Microsoft Wireless Optical Mouse 2.0A.
