Abstract
A portable computer has a base unit and a flat panel display unit. The base unit has a keyboard and a turntable rotatably connecting to the base unit in a horizontal direction. A display support is fixed to the turntable. The flat panel display unit is pivotally connected to the display supporter. The flat panel display unit rotates in the vertical direction between a closed position for covering the keyboard and an open position for operating the keyboard. The flat panel display unit rotates with the turntable in a horizontal direction between the open position and a twisted position for twisting the flat panel display unit. A display stopper prevents the flat panel display from rotating in the vertical direction when it is in the twisted position.
