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:
- Remove the batteries (you don’t want to be clicking everything while you’re prying at the mouse body).
- Use an iFixit plastic or nylon pry tool to get between the shell at the palm end of the mouse under the Windows logo.
- 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.
- 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.
- 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.
- Replace shell by sliding the buttons onto the latch hooks, then wiggle the back tabs gently over the retention pegs.
- Replace the batteries and test out your rejuvenated mouse, ready for another 5 years of clicking.
