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. In the event that the personal computer is turned off; or the personal is not docked to the system; or the power supply within the system is unavailable, the various data, address and control signals in the flexible multimedia system are disconnected to prevent any loss of data or any damage to the personal computer and the flexible multimedia system.

Apparatus and method for automatically disconnecting address and data

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. The modular hard disk drive cavity is adapted to receive a modular hard disk drive which can be relatively easily removed and installed without opening the computer housing. In addition, a cavity may be provided which is closed by an access cover which includes one or more standard in-line memory module (SIMM) sockets to enable additional SIMMS to be added without opening the computer housing. The CPU in the modular portable personal computer can also be rather easily and quickly replaced. In particular, a cavity is formed in the bottom of the portable personal computer and carries an electrical connector that is electrically connected to the mother board. A CPU mounted on a printed circuit board (PCB) is adapted to be received in the cavity. A mating connector is provided on the PCB to enable the CPU to be connected to the motherboard. An access panel provides access to the cavity to enable the CPU to be replaced without the need to open the computer housing.

Modular portable personal computer

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.
