Mouse & trackpad

Mouse double clicking on its own

When single clicks open things twice or drag-and-drop lets go, a worn switch is the usual cause. Run the 20-click test above to confirm before changing anything.

Start with a quick test

Steps

  1. 1

    Confirm with the test

    Make 20 slow, deliberate clicks in the double-click test. Two or more phantom doubles means the switch is faulty.

  2. 2

    Check the double-click setting

    On Windows, open Settings › Bluetooth & devices › Mouse › Additional mouse settings and look at Double-click speed. A very slow setting can make separate clicks count as a double.

  3. 3

    Discharge static

    Unplug the mouse (remove batteries if wireless), then press each button 20–30 times. This sometimes helps a switch that builds up charge.

  4. 4

    Blow out dust

    Short bursts of compressed air into the gap around the button while clicking.

  5. 5

    Raise debounce in the mouse app

    Some gaming mouse apps let you set debounce time. A higher value hides chatter, though it doesn't repair the switch.

  6. 6

    Warranty or replacement

    Mouse switches wear out. Many makers replace mice within warranty; the test report above can support a claim.

Still not working?

  • Test the mouse on another computer: if it double-clicks there too, it's the hardware.
