Mouse Cursor Moving on Its Own: 7 Possible Causes & Fixes

If not all, most of us have had some kind of run-in with our mouse cursor moving on its own and it can get annoying, even problematic.

There are many reasons why a mouse could decide to lead a life of its own and stop listening to our commands. Some of them are a quick click away from a fix and some might require a bit more effort to fix.

So, if you have a mouse cursor moving on its own, whether that be via your mouse or touchpad, here are a few things to check off the list.

Possible Cause #1: Faulty Hardware

There’s always a good chance that your mouse cursor is going on an adventure due to hardware. So, the first step should include checking your mouse cable, whether it is plugged in correctly, and checking the port.

If you have a wireless mouse cursor moving on its own, then it’s a good idea to check the USB & USB port, as well as recall the last time you had a battery change.

If you use a touchpad, then it could have accumulated dust which is making the cursor malfunction.

How to Fix:

Depending on which of the above could be the faulty hardware causing the movement, then you should act accordingly. For instance, for a faulty cable, you can try fixing it or replacing the mouse; whereas, for a faulty battery, a battery change will suffice.

Possible Cause #2: Touchpad Settings

If you use a mouse, there is a good chance the source of your issues is hiding in touchpad settings. If you have your touchpad movement speed and sensitivity set to high, it is possible that through your hand movement, you are moving the mouse cursor both with your mouse and your touchpad.

Similarly, if you are using your touchpad, high cursor speed or sensitivity could cause you to move your mouse cursor without intending to.

How to Fix

Go to touchpad settings:

The screenshot below shows normal mouse cursor speed. If your mouse cursor speed is set much higher then try turning it back down and see if it fixes the problem.

For sensitivity check, open the taps section, and if it is set to any other sensitivity, try medium sensitivity, as shown in the picture below.

You can play around with the settings and see if moving them around fixes the problem for you. If not, check out the other possible causes!

Bonus tips:

  • If you don’t use your touchpad, then you can turn it off while using your mouse. 
  • If your touchpad has accumulated dust, it could very well be the reason your mouse cursor is moving on its own.
