Portable electronic units including notebook computers, PDAs and battery operated units

A portable computer-display unit having a notebook-like arrangement having two leaf structures, in which a user has an option to open and close like at book, the portable computer display unit comprising:

• a) a flat panel display assembly defining a first leaf structure, comprised of a display device, display screen, drive electronics, battery, and control electronics;
• b) microcomputer system electrically interfaced to said flat panel display device, said microcomputer system having a microprocessor unit, data storage means, input/output means and control circuitry;
• c) a roughly transparent cover panel of a second leaf structure, which is essentially flat in two dimensions and hinged to said first leaf structure at one edge of each leaf structure, wherein said user can open and close the two leaf structures like a notebook;
• and
• d) said transparent cover panel being sufficiently transparent and being a least the size of said display screen so that said display screen information is viewable when said leaf structures.

A notebook computer having a clam shell like structure having two leaf halves that a user can open and close like a book, the notebook computer comprising:

• a) a display assembly having a flat panel device, display screen and control electronics;
• b) a cover assembly pivotally attached at one edge of said display assembly via a hinge means, wherein the user have options to open and close said display assembly and cover assembly like a book;
• c) a relatively thin sheet-like member interposed between said display assembly and said cover assembly is pivotally attached to said hinges means, wherein said thin sheet member serves in-part as a physical protection function;
• and
• d) said thin sheet-like member is roughly the same length and width as said cover assembly or display assembly, wherein said sheet-like member can be pivotally moved back and forth like a page in a book.

A battery operated portable electronics unit adapted for quick and easy battery means replacement so that a user can refresh said battery means, the portable electronics unit comprising:

• a) a power unit having a battery source, first electrical connection means, and first housing enclosure structure forming a part of the external enclosure structure of said portable electronics unit, said power unit having a top and bottom external surfaces;
• b) a unit assembly having support electronics, second electrical connections means and second housing enclosure structure, wherein said electronics unit is adapted to physical attachment and electrical connection to said power unit;
• c) said power unit and said support electronics are adapted to physical attachment onto an external surface of said second housing enclosure structure, and adapted to electrical connection to said unit assembly, wherein electrical mating is accomplished via electrical connector means, and wherein said physical attachment of said housing enclosures structure is accomplished via external surface connection and latching means;
• and
• d) said external surface connection and latching means is adapted to quick release and attach-functions. having-finger-or-hand-actuated-mechanical-release-and-latching-function.
