It’s not uncommon for a mouse wheel to suddenly stop working or jump around indiscriminately. Before throwing away your faulty mouse, there are a few troubleshooting methods you can try that might get your mouse wheel working again.
Why is the mouse wheel not scrolling on PC?
The reasons why the mouse wheel does not work can be roughly divided into the following three categories:
- Software errors such as programs or drivers
- Physical failure, such as damaged accessories, something else stuck on the roller, etc.
- Insufficient battery
Here are 10 things to try, based on common reasons why your mouse wheel stops working.
1. Reconnect your mouse to the computer
The first thing you need to do is to reconnect your mouse to your computer. A loose or incorrect connection will affect the normal operation of the mouse.
If using a USB-connected mouse, try unplugging and replugging the USB plug to test. If that doesn’t work, try another USB port.
If it is a wireless bluetooth mouse, please delete the mouse device in the bluetooth device list, then restart your mouse and computer bluetooth, and re-pair the mouse.
2. Restart the computer or application
If your mouse wheel doesn’t work in a particular program, then close and restart that program. At the same time, restarting your computer is also a good idea.
3. Replace the new mouse battery
If your mouse has a replaceable battery, try replacing it with a new one. When the battery is low, the mouse will be delayed, the buttons will sometimes not respond, and the scroll wheel will not respond. Replacing the mouse battery is an easy and inexpensive solution
4. Clean the mouse wheel
There are narrow gaps on both sides of the mouse wheel, and dust, food residues and other impurities will continue to accumulate under long-term use. When these dirt accumulates to a certain extent, it may affect the normal scrolling of the mouse wheel. Use the hair dryer to turn on the cold air to the maximum gear, and blow it at the mouse wheel for 1-2 minutes. You can roll the wheel while blowing, which will remove the impurities between the gaps of the wheel to a certain extent.
5. Change the mouse wheel settings
If your mouse does not work properly in all applications, please go to [Mouse Settings] to change the mouse wheel settings. To change these settings, press the Win key, enter “Mouse Settings” in the search box, then click [Mouse Settings], and adjust the parameters in the [Scroll] field on the page that appears.
If your mouse has a standalone driver, try changing the mouse wheel setting in the standalone driver.
6. Enable/disable scrolling inactive windows option
If your mouse wheel doesn’t work only in a single program like Chrome, then enabling/disabling the option to scroll inactive windows may help you
Click the Windows Start button or press the Windows key on your keyboard and select Settings in the window that appears.
Select Device Options.
Find and click the Mouse option in the left pane of the window that appears.
Now find the Scroll Inactive Windows option and disable/enable it.
Try disabling and enabling this option several times and check if the problem is resolved.
7. Disable browser extensions
If the mouse wheel does not work properly after installing the browser extension, you can try disabling the browser extension.
8. Update the mouse driver
Connect your mouse to another computer, if the mouse does not scroll properly on other computers, then the problem is with the mouse itself, please ignore this method. If the mouse scrolls normally on other computers, then the problem may be with your computer’s drivers. In this case, you can try updating the mouse driver to enable the mouse wheel. Do the following:
- Click the Windows icon or press the Windows button, go to Device Manager in the window that appears, and click Device Manager that appears
- Find the mouse and other pointing devices in the pop-up window and double-click
- Double-click the option that appears below
- In the window that appears, click on the driver in column 2
- Click Update Driver Below
Wait for the program update to finish, then test with the mouse. If the mouse returns to normal, the step ends. If the mouse wheel still doesn’t work, repeat the above steps, selecting the uninstall device below for the updated driver in step 5. After uninstalling, shut down and restart. The Windows system will automatically reinstall the mouse driver
Tip: Some brands of mice have proprietary mouse drivers. While the mouse driver that comes with Windows will work with most mice, there are occasional problems. Check whether the mouse brand has an official driver, if so, please download the latest brand driver.
9. Repair or re-install Windows/Mac system
If the problem is on the computer, not the mouse, you can try to use the system repair or restore function. Take Windows 10 as an example, the operation steps are as follows:
- Press the Win key to open the “Start” menu and find “Settings” in the menu
- Open the Settings interface and find “Update and Security” in it
- Open Update and Security, click “Recovery” on the left, and then click the “Restart Now” button in Advanced Startup
- The system will automatically enter the security operation interface at this time, select “Troubleshooting“
- Enter the troubleshooting, select “Advanced Options“, enter the advanced options
- Advanced options include System Restore, Startup Repair, Command Prompt, Startup Settings, etc., select “Startup Repair“
- Select an account to operate
- Enter the password, the default account has no password and click Continue directly, and other accounts enter the corresponding password
After completing the above steps, the Windows 10 system starts to repair automatically, and then try the mouse wheel after the repair. If it doesn’t work, you can try the system restore in step 6, but you need to pay attention to the system file backup.
10. Buy a new mouse
Buying a new mouse is the most straightforward and effective method, but it’s also often the most expensive. This is also the most feasible method if you have problems with your mouse hardware. For someone who doesn’t know much about mouse manufacturing, it would be very difficult to fix a mouse with hardware problems by yourself.
