How is your mouse wheel holding up? If it’s sticking or just not working as responsively as when you first got it, that’s actually quite common. I think most of us will agree that Logitech makes quality wireless mice, but it isn’t immune to mouse wheel problems. Luckily, most of them can be solved by simply cleaning out the mouse wheel chamber, and this will show you how to do that for most Logitech mouse models.
What you’ll need
- A very small-headed Phillips screwdriver.
- A small flathead screwdriver or a butter knife.
- A small piece of stock paper or a Q-tip.
- Optional: Compressed air can
So, you have the mouse and it’s ready for maintenance. In order to do any work on it, we will first have to separate the top shell from the bottom. The bottom cases all of the tech components as well as the batteries and optical or laser sensor. Flip the mouse so it is upside and get ready to work.
The first thing you’ll need to do is to turn off the Mouse and pull out the batteries.
Next, we need to expose all of the screw holes. Most Logitech models have 3 or 4 screw holes. These are located underneath the larger surface pads, so you’ll have to remove them. I find the easiest way to do this is by prying them with a butter knife or a flat screwdriver. Just do it slowly and they won’t be damaged. Additionally, you may need to remove a battery sticker to expose a screw hiding in the battery bay.
- If you remove the surface pads and battery sticker carefully you can reuse them. The underside has an adhesive, so try not to let it touch anything except for the part of the mouse it is supposed to attach to.
Unscrew all of the screws and the top shell should separate from the bottom of the mouse. Don’t force it apart! It should be extremely easy to separate if you feel any resistance at all it is likely because you missed a screw.
- Warning – be very careful opening the mouse as there is a cable connecting the top to the bottom, and if you break this your mouse won’t work anymore.
Once you have the mouse open, there will be one long cable that connects the top to the bottom. This cable can be unplugged to make things easier. On the bottom half of the mouse, the connection port is easy to access. Make a mental note of which side is which, because it will need to be reinserted facing the same way. In the case of my mouse, the red line is facing outwards away from the center of the device.
Gently pull on the cord to remove it. Close to its end, there should be hard plastic reinforcement to make pulling it out safer.
Now you’ll have unhindered access to the bottom components of the mouse. This is where you grab a Q-tip or piece of stock paper and do some cleaning. Just insert it around the sides and scrape out as much as you possibly can. Compressed air can also come in handy. If you’ve had your mouse for a year or longer then chances are a lot of dust, lint and fuzz are going to come out of the mouse wheel chamber as you clean it.
- Note – It’s possible to completely remove the mouse wheel from the chamber and give it a thorough cleaning. However, in precision and performance models this can be very complicated as there are springs and other mechanisms that are easy to mess up.
Once it is cleaned all you have to do is reassemble the mouse in the reverse order.
- Attach the long cable from the top to the bottom.
- Put the mouse together and reinsert all of the screws.
- Test the mouse wheel to make sure it works.
- If it works, place the surface pads back over the screw holes, re-insert batteries. Done!
- If it doesn’t work, try cleaning out the mouse wheel chamber some more.
I hope this helps anyone who has issues with an unresponsive mouse wheel. I’ve had my Logitech MX1100 Pro for about three years now and it recently started acting up. After going through this process I found that it had an entire ball of lint gathered up beneath the wheel in the mouse chamber. Now with the lint removed, the mouse is working just as it did the day I opened it out of the retail box.
If this were a wired mouse, I wouldn’t go through all the trouble, but a wireless mouse isn’t a cheap and disposable. I’d love to hear feedback from anyone who tries this or has already done something similar to fix mouse wheel issues on any brand of mouse.
