You may need to update your mouse settings. You will find this in your control panel, under hardware and sound. You will then go to device manager which is under devices and printers. Another window will pop up and you will right click on mice and other pointing devices. A button will pop up, scan for hardware changes. This will update your mouse to most recent device settings. It may take a moment. If this doesn’t work you may need to slow down the pointer speed on your mouse.

Jittery touchpad causing erratic mouse control is most often caused by poor grounding, especially when the issue comes on suddenly. Over time, the internal buffering (such as a capacitor failure) of power likely starts to fail. Use a buffered power strip and the mouse cursor should behave better.

try reinstalling the windows and check if pad is working okay. If still problem appears after updating the PC in settings>update & security, Then, Go to lenovo official website. download lenovo service bridge and lenovo system update. Let the Lenovo system update app handle the rest. keep your device connected to charge and ensure not to interrupt because your bios will be flashed and updated. Don't select / mark the option Download deferred only in Lenovo update window. after every update, restart will be required several times. every time, manually open the app and check for next update. 3 or 4 software and firmware updates and boom - you problem solved after final restart demanded by pc itself after some time.
