Abstract

The functions of a palmtop personal computer (PC) with a standard format keyboard (keyboard) are integrated with a personal digital assistant (PDA) having a touch-screen display with PDA control buttons to form a combination computing device. The PDA section is hingedly coupled over the keyboard of the palmtop PC section allowing the PDA display to have two positions. In the PDA position, the PDA section is placed over and latched onto the palmtop PC section. A display position sensor generates a signal indicating that the display is in the PDA display position. The display circuitry formats the display data for a portrait display mode for the PDA mode. If the PDA section is positioned for the palmtop PC mode exposing the keyboard, the display position sensor signals the display circuitry to format the display data for a landscape display mode. A user input may override the display format in the PDA mode.
