Abstract: Systems and methods support docking of an Information Handling System (IHS) to a docking station. A docking connection is detected from the IHS to a docking station that provides use of peripheral devices that are coupled to the docking station. However, the docking station is determined to be unrecognized such that it is not associated with a docking profile in a library of docking profiles available to the IHS.
