Abstract: An information handling system sets, in response to a power event, a discrete graphics processing unit to transmit graphics data to an external display monitor and an internal display panel. In response to determining that a hybrid graphics mode is enabled and that a video driver has been loaded, the system switches a source of the graphics data to the internal display panel from the discrete graphics processing unit to an integrated graphics processing unit while keeping the discrete graphics processing unit to provide the graphics data to the external display monitor.

Abstract: An edge connector for coplanar coupling of two printed circuit boards (PCBs) comprises an elongated body and two end structures. The elongated body has a compression contact space and two PCB contact surfaces, each PCB contact surface having a plurality of contact positions. Portions of compression contacts positioned in the compression contact space extend through contact positions on both PCB contact surfaces. When a PCB edge surface contacts a PCB contact surface of the elongated body, an edge connection on the PCB edge surface contacts a compression contact, forming an electrical connection. Each end structure has two contact pairs, wherein each contact pair has attaching features that couple the edge connector to a PCB to maintain the electrical connection. When two PCBs are coupled to the edge connector, the compression contacts form electric paths for conducting power and/or communication between the two PCBs.
