Don’t overlook the single screw visible just below where the USB dongle (Universal Receiver) nests under the battery cover.

Don’t bother cutting/peeling back the label inside the battery compartment, just poke your driver around until you feel it settle into the head of the screws.

Near the lower left corner of the “skate” is a slot for a thin flat head screwdriver to start lifting the skate. Once, it is partially lifted, rotate the handle of the driver to gently peel it away, don’t scrape off the adhesive by sliding the driver around.

I had a problem with the right click: I solved with a shim on the little switch

THANK YOU VERY MUCH!!!! Had the exact problem and this allowed me to fix it. I cut out a piece of semi-hard thin plastic from a retail package (any kind will probably do). I used strips of 2mm cell phone repair tape to stick the shim to the underside of the top shell of the mouse, since I wanted to be able to remove it and put a thicker shim if needed, but this worked. The same type of thin double sided tape worked great to reattach the rubber pad covering the top two screws.

I had no idea they had screws under the label. Optic popped out of the snapcasing; popped it back in, saved $30 replacing my mouse. Nice guide.

Had issues left clicking to highlight…micro switch had intermittent contact. Nice how-to to find all the hidden screws. Used 2 layers of aluminum tape (really good stuff!) to build up the pads that hit the micro switches. works great now.

My issue was that I’d dislodged the photo receptor and laser when I dropped my mouse. I was able to reseat it, and test the mouse, then I added a dab of hot glue to keep it seated the next time I drop it.

1) There is an additional screw that is already removed on the first picture : under the USB stick emplacement.

2) It is not necessary to remove the rubber. Just peel it with something thin, because the screws are very lateral

3) Be careful while disassembling the top, it is plugged to the base by a 3 wires connector (white/red/black on the Step 4 picture).

Nice simple guide. I used it to quickly take apart a M705 where the laser stopped working after it fell. I didn't do more than reseat the connector cable, but it seems to work again now !

Philippe Puech's comments are good. In fact I wished I'd noticed his 2) before removing the rubber, as the lower layer distorts and doesn't fit back well on a complete removal. His comment puzzled me at first, and might be better phrased as "Peel back the rubber from each side to expose the Left and Right retaining screws. "

A screw bit labelled PH1 (Philllips Head 1) seemed to fit the screws well.

Additional tear down. When removing the top cover with the pre-mentioned 3 wire connector. There are two screws which hold down the silver/grey skin or cover. I had to remove mine as the alignment of the left and right buttons had changed and allowed them two to touch. This alignment issue also caused issues with the scroll wheel where pages where constantly changing position or “jumping”.
