Download the latest version of the device drivers. You can download the latest drivers from the official Lenovo website at http://www.lenovo.com. Problem: Mouse does not work as expected (pointer jittery, jumpy, slow or fast; mouse buttons not working properly). Troubleshooting and problem resolution: 1. Change the mouse properties to adjust pointer movement speed. 2. Try using a different surface to see if the mouse's performance improves (Recommend to use a mouse pad). 3.
