Abstract
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. 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
298 words
A modular personal computer system comprising: a motherboard; a first housing for carrying said motherboard, said first housing including one or more predetermined bays formed from one or more interior cavities open on one predetermined side and having a predetermined size to enable said interior cavities to be accessible from said predetermined side, said interior cavities sized and shaped to receive correspondingly sized and shaped modules inside said interior cavities; a first predetermined electrical connector carried in an interior portion of each of said one or more first interior cavities, said first predetermined electrical connector electrically coupled to said motherboard; a predetermined module adapted to be received in said one or more interior cavities, said predetermined module comprising a second housing for housing a standard peripheral device, said module sized and shaped to be received in said one or more interior cavities and a second predetermined electrical connector carried by said second housing, said second predetermined electrical connector being configured to mate with said first predetermined electrical connector when said second housing is fully inserted into said one or more cavities; an external bay adapted to be mounted externally to said first predetermined housing; said external bay including means for enabling said external bay to be electrically coupled to said motherboard, said external bay formed with a second cavity open on one side and sized to be substantially the same size as said first interior cavity to enable said one or more predetermined modular devices to be interchangeably installed in said first interior cavity; and an electrical connector carried in an interior portion of said second cavity in said external bay and configured to mate with said electrical connector on said modular device when said modular device is fully inserted in said second cavity and said external bay.
Claim 2
Dependent Claim
