The connector is part of the system board, which is the component you will need to replace. [URL]  
Does anyone know if the docking station port at the bottom of the Dell Latitude E7470 can be replaced? Mine recently went bad, probably from how often I docked/undocked it from the E-port docking station, and I want to know if I need to replace the port or switch to a usb docking station. I mainly need the docking station for extra monitors. Also I did check the docking station with another laptop, and it worked fine. So I know that it's not the docking station that is the problem.
