I can’t find any way to open this kind of mouse. My mouse wheel doesn’t scroll and I feel like I could repair it but I have absolutely no clue how to open this up. Screws are nowhere to be found. I’d have to have to send it to be fixed via warranty or buy a new one altogether.
Use a spudger or flathead screwdriver to peel up the adhesive pads on the bottom of the mouse, then stick them down on a table or smooth surface. Under the pads there should be phillips screws. Undo the phillips screws. Finally, if the mouse has not already come apart, gently lift the top and bottom pieces apart.
