Step 2

  • Now turn over the mouse, and gently move the top of the mouse towards you, with a little wiggle. The result should be that the cover of the mouse gives room, and you can take of the cover of the mouse (with the wheel). Here you can see the lips on the wheels side that should slide of the protrusions of the bottom side.

Step 3

  • The PCB inside the mouse is stuck into place with 3 holders. The easiest way to hold these back is with a set of picks. I put a pick on the bottom and the right side and was able to wiggle the PCB out of its position. Be careful with the battery springs which are attached to the PCB, make sure they do not bend or be left in the bottom.
