Please try the following troubleshooting steps:

1. Gently tap the mouse and use a hair dryer on a cool, low setting to blow away any dust or debris around the scroll wheel.

2. Replace the batteries and clean the sensor area on the bottom with a soft cloth.

3. Unplug the USB receiver and plug it into a different USB port on your computer.

4. Try using the mouse with another device and on a different mouse pad to check for compatibility or surface-related issues.
