Logitech sells a wide range of computer mice, both wired and wireless. Even though different mice have different buttons and features, the way to fix them is pretty much the same for all of them if they stop working. You can try a number of troubleshooting steps on your own before calling Logitech for help.
Make sure the Logitech mouse is firmly plugged into your computer’s USB port or serial port, if it is a wired mouse. If you have a wireless Logitech mouse, make sure the receiver is plugged into the USB port on your computer and that the batteries inside are fully charged.
If you are using a wireless mouse, make sure there is no radio interference in the room where your computer is. Take out any 2.4 GHz wireless phone lines, Bluetooth devices, or even microwave ovens that are in the room. Check the manual for your wireless mouse to make sure you’re not moving it farther away from the receiver than it can go.
Click “Start” on your computer’s task bar at the bottom and then click “Control Panel.” Click “Add or Take Away Programs.” If you installed Logitech software when you first got the mouse, choose the option to get rid of it. Go to the Logitech website in your web browser (see Resources below). Go to the “Downloads” page for your mouse model and then download the most recent software. Wait for the file to finish downloading, then double-click on it to install the program.
Go back to the Control Panel and click “Device Manager” from there. To move your mouse, press the plus sign next to the heading. Right-click on your mouse’s name, and then click “Properties.” Click on “Drivers” and then “Find Drivers.” If the driver you have is out of date, you can choose to download a new one.
If your Logitech mouse has a track ball, pull the ball out of the top of the mouse. Dust can be wiped away with a paper towel, and then the ball can be put back in. If your mouse is not a track ball, turn it over and look to see if it has screws holding the sensor in or just a sliding piece of plastic. Slide the piece of plastic in a circle, then pull it off or use a screwdriver to take out the screws. Use a paper towel to gently clean the inside of the mouse, and then put the plastic cover back on. Try to use the mouse again, and if it still doesn’t work, contact Logitech’s customer service.
