ABSTRACT:
An apparatus and method for expanding a portable computer keyboard (6) to approximate a full size desktop keyboard. The device and method include a linkage assembly (8) for automatically separating first and second keyboard portions (44, 46) from each other when the display module (22) of the computer is opened into its operating configuration. The linkage assembly is further adapted to automatically move the keyboard into a collapsed position when the display module is closed into the carrying or carrying configuration. In one embodiment, the keyboard portions are pivoted away from each other to form an angle therebetween to improve user hand and wrist orientation during use of the keyboard.
