Surface Mouse Left-click Quick Fix

My Surface Mouse was annoying me with unreliable left-clicking so I decided to try something that had helped with Nintendo Joy-Con stick drift and clean the contacts with alcohol.

To my surprise, even though the mouse is 5 years old at this point (launched in 2016 with the Surface Studio), I couldn’t find any teardown videos or iFixit content on this particular mouse.

Here’s how I fixed it:

  1. Remove the batteries (you don’t want to be clicking everything while you’re prying at the mouse body).
  2. Use an iFixit plastic or nylon pry tool to get between the shell at the palm end of the mouse under the Windows logo.
  3. Going up the middle will get you between two tabs – pry them to each side to release them from the pegs molded into the mouse body.
  4. Lift the rear of the shell off and slide the shell toward the front (buttons) end of the mouse body and it will release from the front latch hooks.
  5. Use a cotton swab dipped in 70% or higher isopropyl alcohol to scrub the contact buttons and click them with the tip of the cotton swab ten or so times.
  6. Replace shell by sliding the buttons onto the latch hooks, then wiggle the back tabs gently over the retention pegs.
  7. Replace the batteries and test out your rejuvenated mouse, ready for another 5 years of clicking.
