This happened to me last week on the same day as you posted your question, spooky!

To fix it I found this repair guide, which suggests that the gesture button can get stuck if it gets pressed... wrong.

I used this teardown guide to open the mouse up with an iOpener to soften the sticker adhesive and a metal spudger to peel it up, then broad tweezers to prevent tearing or grease from my fingers, I followed Steps 1-2. Then the first part of Step 3 to remove the black screws. I tested the button and its mechanism. Both seems to actuate fine, so I reattached it without tightening fully to give it a little wiggle room.

Once I reassembled the mouse and used the iOpener to soften the adhesive and smooth it back down the the metal spudger, it worked as good as new, if a little more crinkly on the bottom, which is undetectable in normal operation.

I had the same problem, following these steps I solved it. Thank you!


works like charm


It helped me a lot! I just untightened the screws of gesture button twice, in first time it was also helpful, but after one hour the problem started again, after the second untightening is it good. Thank you a lot! My wife has a gold standard "new" mouse after that fix :)


Perfect, thank you so much... Even our shop told me my mouse was dead... And need to be changed.

With you tips, my mouse is now working as usual !!!



Jest letting people know that this solves the same issue for the original MX Master!
