The mouse wheel click does not respond to the failure to respond to the problem of bad contact, driver problems or abnormal system settings, rather than hardware damage. 1. First check whether the roller is stuck or loose, and confirm whether the wireless mouse is sufficient; 2. Clean the micro switch below the roller, lightly push it with a toothpick and spray electronic cleaner or press more to test; 3. Update or reinstall the mouse driver, operate it through the device manager or go to the official website to download the latest driver; 4. Test whether the roller function is disabled or conflicted by the software, change the application test and close the third-party control software to check the settings. In most cases, the above steps can be solved. If it is invalid, consider replacing the mouse.
The mouse wheel click does not respond. In most cases, it is not that the hardware is completely broken, but that it is poor contact, driver problems or abnormal system settings. It is actually not difficult to solve, and it can be basically done by following the steps.

1. Check the physical status of the roller
First, make sure the roller is stuck or too loose. Some mouse rollers have mechanical structures, and over time, they may accumulate dust or the spring fails, resulting in no response when pressing. You can try to twist the roller gently a few times to see if it can restore a little feedback. If the roller is obviously loose or even falls out, it may be that the internal structure is damaged, and it is more practical to change the mouse at this time.
In addition, if it is a wireless mouse, don’t forget to check whether the battery is almost out of power. Sometimes insufficient power can cause the button to fail.

2. Clean the roller micro switch
The scroll wheel clicks did not respond, because it was dirty because it was slightly moved. A small switch is a small switch below the roller. Every time you press the roller, it will trigger a click signal. After long-term use, dust may enter, affecting conduction.
You can try the following methods to clean:

- Use a toothpick to gently push the middle position of the roller (a small hole can be seen from the bottom or side)
- At the same time, spray some electronic cleaner in (also alcohol is OK if you don’t have one)
- Press the roller a few times more to see if it can be cleared
Be careful not to use too much force to avoid crushing or deforming the micro movements.
3. Update or reinstall the mouse driver
Sometimes the problem is not the hardware, but the software level. For example, if the driver error occurs or the system is not compatible after the system is updated, it may also cause the scroll wheel click to be invalid.
The operation suggestions are as follows:
- Open Device Manager → Find your mouse device
- Right-click to select "Update Driver" or "Uninstall Device"
- Then restart the computer and the system will automatically reinstall the driver
If you are using a branded mouse (such as Logitech, Razer, etc.), you can also download the latest driver and install it on the official website.
4. Test whether the scroll wheel click function is disabled or conflicted
Sometimes, the function of the scroll wheel click may be intercepted or mapped to other operations by other software, such as setting shortcut keys in the game, or using certain mouse enhancement tools (such as X-Mouse) to change the default behavior.
you can:
- Change the application and test the scroll wheel click (such as browser, Word)
- Try turning off third-party mouse control software
- Check if there are any abnormal settings in "Settings → Devices → Mouse"
If it doesn't work in all software, it's likely that it's a hardware problem.
Basically these common ways of dealing with it. First eliminate software and setup issues, and then check the physical structure. Most of the time, the cleaning driver repair can be done, and if it really doesn't work, then consider changing the mouse.
