Abstract
A portable computer is disclosed with a base, a display module containing a flat-panel display, a heat-spreader positioned to the rear of the display module, an insulating rear cover on the opposite side of the heat-spreader from the display module and serving at least in part as the rear outer surface of the portable computer for maintaining cool temperatures on the rear outer surface of the portable computer, and means for moving the heat-spreader and the insulating rear cover close to the display module when the portable computer is not being used, and for moving the heat-spreader and insulating rear cover a distance away from the display module when the portable computer is being used, and preventing touch access to the heat-spreader. Many structures are disclosed for the efficient cooling of the heat-spreader.
