Things You'll Need

Instructions

1

Use the mouse on the same side of the computer where the Logitech USB transmitter is attached so there is a clear signal between the transmitter and the mouse.
2

Check the USB transmitter that comes with the Logitech mouse to be sure it is correctly plugged into the computer. The red LED should be illuminated on the transmitter if it is connected properly. If not, the signal cannot reach the cordless mouse.
3

Turn the mouse upside down to check the on/off switch. Be sure it is switched on.
4

Check the battery compartment by sliding the top housing off the mouse to confirm the rechargeable batteries are installed correctly.
5

Charge the batteries if the mouse LED does not illuminate. The charger cord plugs into the front end of the mouse and the other end connects to a free USB port on the computer.
6

Clean the desk surface or other flat area if the mouse is not tracking. The problem could be dirt or grease interfering with the tracking ability of the device.
7

Open the Logitech software called SetPoint, which manages the mouse, to troubleshoot button functions. Open the program by double-clicking SetPoint from the list of software on the computer, then click "Mouse Settings." Click the "My Mouse" tab and check (or uncheck) all the task boxes that are desired for operating different mouse functions, then click "Apply" and "OK."
