If the cursor does not move or stutters, try a different USB port, clean the sensor window, and test on a non-reflective surface. Intermittent clicks or scroll issues often stem from dust or debris under the buttons or wheel—open the shell carefully to clean and inspect the wheel encoder and switch actuators. If problems persist, check the cable for kinks or breaks near the strain relief and consider replacing the USB cable or the primary microswitch.
