Abstract: A flexible multimedia presentation system is configured to be releasably secured to a portable personal computer to provide additional features, such as a PCMCIA interface, a port replicator and other options. The system is configured to enable the unit to be rather easily transported as a unit. A retractable handle is provided which further facilitates transport of the unit. In order to provide enhanced flexibility of the flexible multimedia presentation system, the system includes a PCMCIA interface, as well as replicates the various I/O ports on the rear of the portable personal computer. By replicating the I/O ports on the portable personal computer, external I/O devices, such as an external monitor, keyboard, mouse and printer can be used when the portable personal computer is docked to the flexible multimedia presentation system.

Abstract: A modular portable personal computer includes one or more flexible bays accessible from the front surface of the computer. One or more of the flexible bays may be configured as a dual functional bay to enable the bay to interchangeably receive different modular devices, such as a modular floppy disk drive or a modular battery pack. With such a configuration, the modular floppy disk drive can be removed for portable operation and an additional battery pack installed to provide increased electrical power to the portable personal computer during portable operation. The portable personal computer is also provided with a plurality of cavities formed in a bottom surface. These cavities allow for various upgrades to be made without opening the computer housing. For example, a modular hard disk drive cavity is provided on the bottom side of the personal computer.

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.
