When Doug Engelbart of the Stanford Research Institute, part of Standford University, debuted the computer mouse in fall 1968, it was much different than what is used today.What was once connected to the computer with a cord and tracked movement with a roller ball is now wireless and uses a light source. When trouble strikes with the functionality of the seemingly critical piece of hardware, sometimes all it takes is a simple reset to fix the trouble.
Reset the Mouse
Locate the reset button. This is typically located on the bottom of the mouse or next to the batteries on the inside.

Using a small pointed object, such as a straight pin or the tip of a ball point pen, push the button and hold it down for three to five seconds.
If resetting a wireless mouse, reset the USB receiver as well to ensure proper functionality. Locate the reset button on the receiver, which is typically located on the underside.
Using the same small pointed object, push and hold the reset button on the receiver for three to five seconds.
Plug the receiver back into the computer and press the reset button on both the mouse and the receiver at the same time. This will allow the device to reconnect to the computer appropriately.
