With the display device disposed in a second configuration, the computer is operable in a second or closed housing configuration.

Claims

1. A computer comprising:

a housing including a base member and a cover member;

a keyboard disposed within said base member, and

a removable display device including an electrical connector means disposed asymmetrically on said removable display device, said removable display device being disposed within said cover member having a first and second socket means for receiving said connector means, said removable display device being reversible between a first configuration and a second configuration within said cover member, while in said first configuration said connector means being electrically connected to said first socket means and while in said second configuration said connector means being electrically connected to said second socket means.

2. The computer of claim 1, further comprising:

means for latching said removable display device within said cover member.

3. The computer of claim 1 wherein:

said removable display device includes a touch screen for inputting data.

4. The computer of claim 3 wherein:

said removable display device operates as a display means while in said first configuration, and

said removable display device operates as a display mans and as an input means while in said second configuration.

5. The computer of claim 3 wherein:

said removable display device operates as a display means and as an input means while said removable display device is disposed within said cover member in said first configuration and in said second configuration.

6. A method of using a portable computer, said portable computer comprising a housing including a base member and a cover member, a keyboard disposed within said base member and a removable display device including an electrical connector means disposed asymmetrically on said removable display device, said removable display device disposed within said cover member having a first and second socket means, while in said first configuration said connector means is electrically connected to said first socket means and while in said second configuration said connector means is electrically connected to said second socket means, said method including the steps of:

configuration said portable computer by disposing said removable display device in said cover member in said first configuration, and while in said first configuration inputting data with said keyboard and displaying output on said removable display device, and selectively reconfiguring said computer by disposing said removable display device in said cover member in said second configuration, and while in said second configuration inputting data with said removable display device and displaying output on said removable display device.

7. A portable computer comprising:

a plurality of housing members, wherein said housing members pivotally cooperate about a hinge means;

a keyboard disposed within a first of said housing members, and

a removable display device including a n electrical connector means disposed asymmetrically on said removable display device, said removable display device disposed within a second of said housing members having first and second socket means for receiving said connector means, wherein said removable display functions as a display while disposed in a first configuration and wherein said removable display function as a combined display and touch screen input means while disposed in a second configuration, while in said first configuration said connector means being electrically connected to said first socket means and while in said second configuration said connector means being electrically connected to said second socket means.
