Logitech G9 repair:
When my Logitech G9 mouse started to "mis-click", I thought that it was time once again to replace a mouse. Again.The problem presented itself as a rare double-click when a single-click was intended. But later, the frequency of these rare occasions went up and it had become a habit of the mouse to randomly double-click or even triple-click, and drag-and-drop operations could not be successfully completed half the time.
I did the sane thing first; that of sending in a warranty support request to Logitech. But while waiting for their response, I read up on this issue, which turned out to be more common among Logitech mice owners. The usual suspect when the clicks start mis-behaving was the micro-switch, or the "clicker", that interprets the clicks. This is also the component that produces the distinctive "click" sound when engaged.
More specifically, the minute, springy copper part of the micro-switch was the culprit. It appears that this copper clicker conducts current to convey a click, and once it starts losing some of its springiness, it does not make a continuous contact which results in multiple-clicks instead of a single-click. Ultimately, it may cease to detect or effect any clicks to that button.
So, the (DIY) solution then, was to open up the micro-switch, take-out the small copper piece, re-shape it to be more springy, re-jig it back into place and close the micro-switch. It was simple enough in theory but without experience in handling tiny, springy metallic parts without losing it or squishing it requires the right tools, steady hands and tons of patience.
Opening up the mouse was pretty easy. I spent about 15 minutes trying to open the small micro-switch though. Once open, getting out the copper part and re-shaping it was easy enough. The hard part was re-seating this newly bent copper part back into the micro-switch. I spent nearly an hour doing this. Every time I almost had it seated, it would either spring out of its position or just fall into the crevices of the mouse's circuit board.
I was clearly missing a special tool or technique to perform this simple and delicate task.
Fortunately, an article over at [Overclockers.com] had a simple but crucial advice on just this operation. Once done, my mouse clicks just as it should. Although now the click sound is a bit more muffled than it was before, I quite like the quite muted clicks. Now I am back to clicking-and-dragging like it's nobody's business.
