Keyboard/Mice - Buttons or keys do not work correctly

Likely Cause(s):

• Potential hardware issue
• Operating system /software settings
• USB port issue

Symptom(s):

• Single-click results in double-click (mice and pointers)
• Repeating or strange characters when typing on the keyboard
• Button/key/control gets stuck or responds intermittently

Possible solutions:

1. Clean the button/key with compressed air.
2. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
3. Unpair/repair or disconnect/reconnect hardware.
4. Upgrade firmware if available.
5. Windows only — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver.
6. Try on a different computer. Windows only — if it works on a different computer, then the issue might be related to a USB chipset driver.

*Pointing devices only:

• If you’re not sure if the problem is a hardware or software issue, try switching the buttons in the settings (left click becomes right click and right click becomes left click). If the problem moves to the new button it is a software setting or application issue and hardware troubleshooting cannot resolve it. If the problem stays with the same button it is a hardware issue.
• If a single-click always double-clicks, check the settings (Windows mouse settings and/or in Logitech SetPoint/Options/G HUB/Control Center/Gaming Software) to verify if the button is set to Single Click is Double Click.

NOTE: If buttons or keys respond incorrectly in a particular program, verify if the problem is specific to the software by testing in other programs.
