Mighty Mouse’s scroll ball

July 28, 2009

Mighty Mouses have a single debilitating flaw. Over time, that little tiny scroll ball, (reminicent of the ball that used to be underneath the mouse) stops working. I don’t know about you, but I might as well pack it up when this happens, because I am not effective without my scroll ball!

It turns out that there’s an easy fix for this, which I just sought out after being crippled with a mouse that wouldn’t scroll down. Here’s what you do:

  1. Lay a piece of paper on a desk
  2. Flip your Mighty Mouse upside down
  3. Press the little ball down firmly on the piece of paper and roll the ball around
  4. Do this a couple of times, flipping rightside up every so often to blow of the gunk that comes out

It’s that easy!

    I have same problem with my mighty mouse, it seems mighty mouse is not that mighty for heavy work such as gaming…
    I clean it using high pressure blower and spray it with some cleansing agent, then let it dried, seems to be working for me…

    If I only had this tip one month ago. I followed a youtube video on how to open it to clean it. The result was a broken mighty mouse…

    Yes, I saw this fix a couple months ago and it worked great for my mighty mouse for a while. Unfortunately, after doing it for several months (maybe I push down on the paper too hard), the mouse actually broke and only recognized secondary clicks. So do this at your own risk, its only a temporary fix for a flawed product.

    Yes, it would be that easy if you only had to do it once every six months or so.
    However, it will also stop working if someone has a slight amount of grease on their finger.
    It got to the point where I was cleaning it at least once a week (also tried rubbing alcohol which works up to a point) and after a while, even more frequently. It got to a point where it still didn’t work right even after a thorough clean (and at that point the optics were also acting wonky).
    So, I went and got myself a Logitech laser mouse. Doesn’t have a neat ball at the top but at least it works without all the frustration.

    Apple’s Mighty Mouse is a great example of a good idea in concept but lousy in execution.

    Here’s another solution:
    Lick your finger. Problem solved.

    I think it`s the best mouse in terms of scrolling. But, to bad the same happened to me. Last time, I ended up rubbing it to firmly against the paper and it works really bad as one internal tiny little piece that composes the scrolling wheel broke. The mouse itselft is fine, but it scrolls really bad.

    Thank-you for this tip. I have spent the last six months moving my mouse to the right of the screen to scroll documents. You have saved me from ever having to endure such torture again.
