optical mouse

How do you deal with an optical mouse that doesn't move right anymore?

It's movement is no longer very smooth.

Is this caused by dust or something else?

Several possibilities:

1) Broken cable, where cable enters mouse.

    If the optical mouse is wireless, check for bad batteries,
    interfering sources (telephone base station), or for
    interference coming from a neighbor.

    I've had a few cables go bad. I pull a hunk of cable inside
    the mouse, cut off the defective wire, and solder the wires
    back into place. The strain relief they use, only helps a bit.
    If you need proof, you can use a multimeter and do a continuity
    check, with the mouse opened up, and the wire pads exposed.

2) If you look at the quality of the sensor,
    they're typically dreadful looking. It's a wonder
    they hold together. The people making those sensors,
    can't seem to make a good housing for the IC.

3) Check for dust and dirt. I might average a year or
    two, between mouse disassemblies. Note that, the mouse
    can be filled with bits and pieces, like tiny springs.
    Work on a brightly lit surface, so you don't lose anything.
    I can't imagine the sweatshop where they'd assemble such
    things (lots of small parts, doesn't suggest automation is
    used). I'm really surprised there isn't a way to make
    the mouse less labor-intensive in manufacturing.

    Most of the time, I need to clean the scroll wheel
    sensor area, and remove dust balls from underneath the
    mouse buttons. I haven't needed to do anything special
    with the sensor.

    The screws are typically hidden by stickers, or by the
    sliders on the bottom of the mouse. You can use a magnet,
    sweep it over the base of the mouse, to get some idea where
    the screws are located.

I would rate "broken cable", high on my list. Dust bunnies
under the buttons, you can tell by the accidental "drop" on
a "drag", that the button needs cleaning. Or just the feel
of the buttons isn't right.

At one time, the optical sensors could be fooled by a particularly
bad choice of mouse pad. I use a rubber pad now (from a
company that knows how to make rubber that doesn't stink :-) ).
The sensor seems to work well on that.

I found this optical mousing surface:

3M Precise Optical Mousing Surface (MP200PS) by 3M  
(Amazon.com product link shortened)

I just got it yesterday, and it is pretty nice so far.  The mouse moves smooth
on it.

Thanks for posting back. I didn't think it would be
the mouse pad, but decided to mention it anyway.
