One morning when I was clicking happily away, my Logitech M185 mouse decided not to follow my gentle taps. I had to press hard to make a left-click. So I thought maybe I could fix that left-clicking problem since I have done it before a long time ago.
Opening up the case
Opening the Logitech M185 is really easy. First, open the battery cover at the back of the mouse. Take the battery out to reveal the screw at the bottom. Then unscrew it, lift up the cover slightly and slide the cover towards you ( mouse on upright position ).
Click mechanism
When you open up the case, there will be two black rectangle boxes on the PCB which are the click mechanisms. My easy solution? Stick a tape or two on the protruding plastic ( where it meets the problematic click mechanism ) at the bottom of the mouse cover. Make sure you use a tape with good adhesive. Cut the tape to match the flat square surface on the plastic. In my case, I pasted two layers of tape.
After you're done, close the case by sliding the cover in the brackets and tighten the screw.
It's still clicking like new for over 3 weeks now, so it's not too bad for such a simple DIY.
If mouse-clicks is still not satisfactory, then you will have to open up the click mechanism box to repair. You can go to
