Thermally efficient portable computer system incorporating thermal connection port and dock

A portable computer system comprising a portable computer mechanically, electrically, and thermally connected to a dock is shown. The portable computer comprises a base assembly containing a microprocessor, media, batteries, and keyboard, and an internal heat moving apparatus thermally connected to the microprocessor. The dock includes a housing with a plurality of connectors and a thermal dissipation apparatus. A thermal connection is made between the portable computer and the dock through a thermal connector port located at the rear of the portable computer base and at the corresponding location on the dock. The portable computer also contains a thermal state monitor and controller subsystem. When the portable computer is connected to the dock, heat is moved from it to the dock via the heat moving apparatus and the thermal state monitor and controller subsystem permits the microprocessor to run at a fast clock-speed. The dock may also contain a thermo-electric unit which increases the amount of heat that can be dissipated in the dock. The thermal connector utilizes thermally conductive springs, or an H-shaped cavity and H-shaped plug, to conduct heat from the portable computer.
