1: the mouse entered a number of dust. Open the upper lid of the mouse and clean the dust inside.2: if the mouse with a rubber ball is the easiest to use because of dust, unscrew the cap, remove the rubber ball, and clean the dust on the wheel.3: may be caused by poor contact with microswitch, buy a switch, change it on, or the left and middle key switch swap, because the middle is not commonly used.4: if the new mouse does not move, it is likely that there is no installation of the mouse driver, it is recommended to download the official website driver installation. Or download Lu master installation prompt installation driver.
