Just give a quick overview of the task for the M705. To be fair, I’m including here a link to the original forum post I used, where they fixed a Logitech G7 mouse, so I won’t repeat everything. I fixed the two mice, the first took me 2 hours or so, the second (the M705) one hour. You’ll need a steady pair of hands, patience and a small screwdriver and thin knife or blade. To fix the problem, you need to dismantle the mouse, open up the black switch casing and restore the bends in the copper to the original shape. What seems to happen over time is the copper flattens out through repeated clicking and once that happens, you start getting unpredictable results and double clicks etc. The actual spring mechanism is a tiny piece of intricately designed copper (top left in the image above) which sits inside the black microswitch housing on the right. The first thing to note is that the culprit is tiny, a sliver of copper which can’t be worth more than £0.02p. And the answer is yes!Ī quick search on Google revealed that other more intrepid souls had managed to fix their own meeces, and so we got to work on two ‘dead’ mice lying around in Ferret Towers, a Logitech M705 and an older MX Revolution. This time, however, instead of consigning the device to the trash and buying another, we decided to see if we could solve the situation with a bit of DIY. The symptoms are that the mouse click delivers two clicks for one press, which can be extremely annoying and renders the mouse unworkable for important tasks.
On the one hand they’re ergonomically designed and feature the wonderfully useful hyperscroll wheel for sweeping through documents and web pages, but on the other they suffer from a fundamental fault after a few years of use, when the mouse buttons start to fail (note that other mice also seem to suffer from the problem, although we’re not sure whether that’s because they’re OEM models made by the Logitech factory).ĭespite our rant four years ago, little seems to have changed, and the other day yet another mouse here, an M705, started failing again for the same reason. We’ve long had a love hate relationship with Logitech mice.
