What you will need:
* A small Phillips head screwdriver
* A toothpick
* Glue of some kind (I wanted to use Elmer's but all I had on hand was wood glue)
* A good working surface
1. First, make sure the mouse is unplugged.
2. Turn the mouse over so that the bottom is showing.
3. Peel off the adhesive sliders. You will want to take care of these so that you can reapply them afterwards. You should be able to slide your thumbnail under the slider to remove it.
4. Take out the 2 screws
5. Gently lift the back end of the cover up
6. After separating the back end, pull back and up to release the tabs on the front of the mouse.
7. You can see the two buttons here. I could see dust and debris from use on mine so I used a soft cloth to clean them. I also blew out any dust or hair out of the scroller and electrical board in general.
8. Now look at the top of the mouse. You can see the two buttons. I could actually see grooves in mine where the plastic had worn from pushing down on the switch located on the electrical board. This is why it was not registering the click!
9. Take a very small amount of glue on the end of the toothpick and place on the buttons. In my case it was easy to place on the buttons due to the grooves. Only a spot is needed.
10. Let the glue dry COMPLETELY before reassembling your mouse. If in doubt of how long this takes, let it sit for at least an hour.
11. To reassemble, slide the tabs at the front of the mouse into place, then pop the back of the mouse back in place. Replace the screws and reapply the adhesive pads to cover the screw holes. Plug in and wah-la!
