The Logitech MX Master is a popular choice among professional users due to its advanced features, ergonomic design, and top-notch performance. However, like any piece of tech, it may occasionally encounter some issues. One common issue users face is the unresponsiveness of the cursor while other functional buttons still work properly. This article provides a comprehensive guide on how to troubleshoot and fix this issue.
Before you start, ensure your mouse isn’t physically damaged and that the surface you’re using it on is suitable for laser mice. Also, check if the issue persists on another device to rule out a computer-specific problem. One last thing to check is the battery, make sure it is fully recharged. If none of the above methods work, the thumb button on your Logitech MX Master mouse is stuck. When this button is pressed, the cursor won’t be able to move. Thereofre, you may need to open the mouse and adjust some internal parts. This is a widespread issue on the MX Master 2S and was addressed on newer models like the MX Master 3/3 Advanced. Here’s how to do it:
- Small Phillips-head screwdriver
- Soft cloth or work mat
- Tweezers (optional)
- Turn off the Mouse: Start by turning off the mouse to prevent any electrical damage or accidental clicks while you’re working on it.
- Remove the Glides: The mouse’s screws are located beneath the four glides (the small pads that allow the mouse to move smoothly). Peel off the glides gently using your fingernails or tweezers. Be careful not to damage them, as you’ll need to reattach them later.
- Unscrew the Bottom Panel: Once the glides are removed, you’ll see the four screws that hold the bottom panel in place. Use your Phillips-head screwdriver to remove these screws.
- Open the Mouse: After removing the screws, gently lift off the bottom panel. Be careful not to pull too hard, as there are delicate components inside.
- Inspect the Thumb Button Mechanism: Check the thumb button mechanism for any visible issues. The problem could be due to the button being misaligned, a loose screw, or debris stuck in the mechanism.
- Adjust the Thumb Button Mechanism: If the thumb button is misaligned, gently realign it. Check if the screws are over-tightened; If they do, loosen them by a quarter turn or until you can press on the thumb button. If there’s debris, remove it.
- Reassemble the Mouse: After you’ve made the necessary adjustments, it’s time to put the mouse back together. Replace the bottom panel and screw it back in place. Then, reattach the glides. Make sure they’re firmly in place, and ensure no edges are peeling up, which could affect the mouse’s movement.
- Test the Mouse: Finally, turn the mouse back on and test the thumb button. It should now move freely and register clicks normally.
