mouse scrolling wildly

[someone]

I would like to tell you about my Logitech M-SBF96 mouse,
which was not working properly, and recently began scrolling
wildly all over any page. At first I thought it was a
virus, but no. I read up on it, but the main suggestion was
to buy another mouse. I spent weeks looking for solutions
on the Internet.

Anyway, as it appeared to be a throwaway anyhow I unscrewed
the single Phillips screw, took it apart, and found that it
was full of cat hair (I have two cats). I cleaned it out,
including the wheel, blew the dust out of it, put it back
together and - voila! So if any of you out there have this
problem, try cleaning your optical wheel mouse before
spending any money on another solution.

Just a word of warning, if taking this advice to heart.

You would think, that mice containing large numbers of
parts, it would cost a fortune to make and assemble them.

But, there are mice like that. Lots of tiny, loose parts inside.

Why is that a concern ? The mouse if filled with wheels,
levers, springs, all sorts of tiny stuff. When you first
take the outer casing off it (easy), it all tamely sits
in place. But some of the spring loaded things can bust
loose, and run amok. And before you know it, you can't
figure out where it all goes again.

By all means, clean your mouse (when it needs it).
But also be aware that you need to have a clear
area on your work table. And be prepared for stuff to
fall apart. Since I have a second mouse, identical to
the first, I could use that as a model of how to put it
all back together again. At least, as long as I don't
touch anything on the second one, until the first is
reassembled

An area to watch for, is anything associated with the "wheel".
That's where my trouble started.

To check the optical sensor area, you might need to lift the
PCB assemblies out of the shell. Again, an opportunity for
that wheel to break loose.

I'm sure the people who build those on the assembly line,
must see those things in their sleep.
