Abstract
A portable computer system has heat transfer mechanisms incorporated therein for transfer of heat to a docking station with active cooling capacity. A portable computer case has openings placed in alignment with mating openings in the docking station to provide additional active cooling capacity. The portable computer system case also has further openings and a defined air flow path to enhance airflow across a processor to cool it more effectively. A fan in the docking station pulls or pushes air from or into the portable computer system case. The mating openings and further openings in the computer system case are positioned to optimize the cooling effectiveness of the air flow with respect to the processor and other heat producing components. Other devices such as refrigeration coils, heat slugs, and heat pipes are also described. A switch detects when the portable computer is connected to the docking station and causes deactivation of processor slowing power management routines.
