Randomly my mouse hand will move on its own?? ?

Question

Not the part I use but sometimes I will be on the computer and I will see the pointy mouse hand just start moving around on my computer screen even though I am not touching it and its not moving one bit?

Why does it move on its own?

Answer 1

That happens to mine ALOT, but mines old so i think it might be old or somthings blocking it.

Answer 2

If it's laptop track pad, then dust is on the pad and it's too sensitive.

If it's laptop ball stick (Thing in middle of keyboard) then it's stuck in a direction and needs fixing.

If it's an optical mouse then the light is reflecting away from the sensor or the mouse is titled at an angle, get a smooth non-reflective surface to use your mouse on.

If it's a ball mouse then there is dirt that is unbalancing the ball and making it turn slightly.

If it's a track ball then the ball needs tacking out and cleaning as there is too much friction on the wheel inside.

Next time say what type of mouse you have.

Answer 3

LAWL well if the surface that the mouse is on reflects any of the beam its going to move haha. So don't use paper.
