Logitech M705 Mouse Button Fix

My Logitech mouse was giving me fits with click-and-drag operations, as when selecting ("highlighting") text to copy, as if it was releasing the button despite my having ample and consistent pressure on the actuator. Apparently the most common Logitech mouse button problem is erroneous double-clicks, but I was only rarely experiencing those. The fix for that can be found here, and is the reference for the rest of this brief article.

The requisite caveats: If your mouse is under warranty, give the problem to Logitech. If you proceed with this fix, you risk breaking your mouse, and the fix might not work anyway. There may be other failures that mimic the one described here. You may be bitten by a radioactive spider but not be transformed into Spiderman. Or you might win a lottery jackpot. Such is life.

If your Logitech mouse button is foiling your attempts to copy text because it's apparently releasing the button, but is not suffering the double-click failure, this fix is easier than is the one for the well known double-click failure. Disassemble the mouse as far as opening the switch as in the article above, but do not remove the copper reed. Instead, cut a couple of strips of printer paper a few inches in length and about ¼" in width. Insert the first small strip of paper between the contacts, which are at the front end of the reed, the end furthest from the battery. Gently close the switch (depress the reed) with a small screwdriver, a pen, pencil, or even a fingertip, and drag the paper through the contacts. Repeat this closing/dragging operation several times, then repeat with the other, clean strip of paper. Then, partially reassemble the mouse with two or three screws, install the batteries, and test. If it proves to be working nicely again as mine is, finish buttoning it up and be happy — you've just saved yourself right around fifty bucks. If instead it's still a bit twitchy, try another clean strip of paper and a bit more cleaning. If that doesn't work, be happy but try some other fix, or replacing the recalcitrant rodent.

A side note: The switch enclosure I encountered was slightly different from the one in the referenced article, in that the locking tabs were on the sides rather than the ends. It's not a big thing, but you should look at the one you encounter carefully, and proceed more carefully. If you apply the correct pressure in the correct place, the cover should come away easily. You don't want to hear the wrong snapping noise!

I recommend a contact cleaning if you're in there to fix the infamous double-click failure, too.

I think I'm going to spend the next few minutes just randomly highlighting text to see it working properly.

Schedule Change, TBD

I gave my "work/life balance" schedule a fair trial, about two years, and have determined that it was just not right for me. When I say "not right" what I really mean is very wrong, as I am about to explain.

It's not really news that many programmers will work at night whenever possible. The two most common explanations given are that (a) the brutal conditions of startup companies place unreasonable demands upon their usually short technical staffs, and (b) those whose primary work requires prolonged periods of intense concentration find the quieter time more conducive to that work. I am wholly unqualified to speak to the former as I've never been directly employed by a startup company, but of the latter I can say that there is some truth to it. I've often said that a two minute interruption can set a project back by two to four hours, and I stand by that. The only time this is not true is when the software project at hand is trivial. But there's more to the story, at least in my own case there is more to it. Another thing I am wholly unqualified to do is to speak for my entire profession, and I won't pretend otherwise. I acknowledge that I might be and probably am an outlier. With that said:

There's more ...
