Middle Mouse Button Not Working

Use the mouse test. If “Middle” lights up, the hardware works.

Logitech, Razer and other utilities can remap the middle button to another action; reset to default.

Device Manager → Mice → uninstall device → restart.

Windows touchpads use a three-finger tap; enable it in Settings → Touchpad → Taps. On Linux enable middle-click emulation.

Dust under the wheel blocks the switch; blow compressed air around it.

As a workaround, assign middle click to a side button in the mouse software.

Hardware issue

If the test never registers middle click, the switch is faulty.

Check that your mouse works

Use the mouse test to see whether the middle click registers at all.

1. Test the button on the mouse test to confirm it is the hardware.
2. Update or reinstall the mouse driver and the maker's software.
3. Run the operating system's hardware troubleshooter where available.
4. Install system updates, then check whether an app remapped the middle click.
5. Clean around the wheel with compressed air.
