Hi Urza,


Welcome to Lenovo Community!


As per the query we understood that you are facing issue with touchpad and keypad in your Z400 laptop.


Try to update the touchpad driver and check for the issue, also try to boot the system to safe mode and check for the issue. The touchpad driver is a inbox driver i.e inbuilt in the operating system.


For the keypad issue check if the issue persists in command prompt, also tries to reinstall the operating system and check for the issue. Also boot the system to the safe mode and check for the issue. Try to uninstall the keypad adapter and restart the system and check for the issue.


Hope this helps. Do post back if issue persists!


Best regards,
