Abstract
A portable computer with a base and keyboard with a pivotal lid assembly containing both a visual display panel and a parallel mounted central processing unit circuit board, as well as coplanar memory and visual display driving circuitry. The lid assembly is provided with front and rear clam shell covers with the front cover holding a bezel around the visual display (an LCD), and the front also provides the supports for the circuit boards in spaced, parallel relation to both the LCD and the rear cover, so when the lid is open and generally vertical, air blows by convection through lower vent holes in the covers, over both sides of the boards, and exits through upper vent holes.
