A computer system is described having additional cooling capabilities in a docking station for a mobile computer. The docking station includes P- and N-doped semiconductor thermoelectric components. The thermoelectric components are connected in series when the mobile computer engages with the docking station. A current flowing through a doped semiconductor causes heat to be transferred either in a direction of a current through the semiconductor component or in a direction opposite to a current in the thermoelectric components, depending on their doping. The thermoelectric components alternate from being P-doped to N-doped and the direction in which current flows alternates accordingly so that heat is transferred in one direction only. A heat pumping effect is created by the thermoelectric components which does not require high-pressure contact upon engagement of the mobile computer with the docking station.
