Touchpad does not seem to be detected on recently purchased refurbished Lenovo Thinkpad T530. Running Ubuntu 16.04 LTS. Touchpad works fine on Windows on internal hard drive. Also, it does work on Ubuntu 17.04.
You can see that running xinput list there is a USB mouse detected but not a touchpad:
*********:~$ xinput list
