I am struggling with my docking station for my ThinkPad 480s. I have two docking stations. One by Lenovo type 40AJ and the other by DELL. The dual monitor DP setup resets every 3 to 5 minutes causing the monitors to go black with the Lenovo UltraDocking Station. So I switched out that docking station with the DELL universal docking station. When I use the USB C/Thunderbolt port the same thing happens. When I use the USB 3 port, I have no problems. I have looked in the event viewer and I can see where the laptop switches from external to battery power, but nothing else. Also, I have updated the drivers for Thunderbolt.
Has anyone seen and resolved this issue?
