T490s not recognizing ThinkPad Thunderbolt 3 Dock Gen 2

Hi, I have a user with a T490s and a new ThinkPad Thunderbolt 3 Dock Gen 2.  The T490s does not seem to recognize that the dock is plugged in.  It is working as a "charger" but on reboot, it gives "The connected AC charger has a lower wattage...." error.


I installed the dock driver from this page:


I updated the BIOS on the T490s and all other software is up to date.  


I'm using the thunderbolt port but have also tried to use the USB C charge port.


From what I understand, the power light should change to white when the T490s and dock are connected.


Any ideas on what to do?
