Abstract
Abstract A portable computer (1) has a base unit (3) and a flat panel display unit (5). The base unit (3) has a keyboard (9) and a turntable (19) rotatably mounted on the base unit (3). A display support member (21) is fixed to the turntable (19) and has a pivotal mounting for the flat panel display unit (5). The flat panel display unit (5) can therefore be pivoted in the vertical plane between a closed position in which it covers the keyboard (9) and an open position for operating the keyboard (9), and can also be rotated by means of the turntable (19) in a horizontal plane. Blocking means are provided for preventing the flat panel display unit (5) from pivoting when it is in the horizontally rotated position.
