Abstract: A compact computer has a base with an alphanumeric keyboard, and a display screen is pivotally connected to the base. In a stowed configuration the display screen faces against the base with one protective shell extending around the rear of the base and another protective shell extending around the front of the base. The two shells are extended from the base enabling the display screen to be pivoted away from the base into a viewing position. With the shells extended from the base, the display screen also can be pivoted into a position against and facing away from the base. This orientation places the display screen in the tablet mode in which information can be entered into the computer by touching the display screen with a stylus. The base also incorporates a retractable numeric keypad and a three axis track ball assembly.
