Does your laptop have an external mouse connected? If so, please remove it or replace it with another mouse and check again.
If the problem persists after removing the mouse, then please confirm whether the problem improves if you turn off the touchpad.
If the problem improves, then it may be a problem with the touchpad. It is recommended to refer to the following FAQ for troubleshooting.
