    My Satellite has a volume wheel like the picture below.

    Used to work great, but lately, the control goes up and down erratically.

    Would blowing compressed air into the socket help? What about disassembling the laptop and cleaning the wheel with alcohol?

    I doubt either will help - if it's jittery then it's because the potentiometer it's connected to has gone crazy. It's a stupid cheap part but good luck finding it.

    Is it the kind that only turns so far and then stops, or is it the kind that can spin forever? It doesn't really affect whether or not you're fucked (which you are), but it does affect the way it probably failed.

    Either way, it's time to warranty that bitch.

    It spins forever.

    The laptop is under warranty. How long will I be without the thing?

    Depends - if you drop it off, a week. If you use their delivery system, service.

    If it spins forever, that means every time it clicks, it sends two little electrical blips along different wires, each triggered by a different side (left vs. right) of the thing that clicks. It's called a grey code. Depending on which wire sends its little electrical blip first, the computer can tell which way the wheel is being turned. If those blips are being sent in the wrong order because some part of the mechanism is worn out, that would explain why the volume doesn't do what you're telling it to do.

    Not that this helps any, it's still fux0red. It's just interesting to know how it works.
