ABSTRACT:
A Portable computer comprises a base unit on which a lid is hinged. The base unit houses an electronic unit which can assume various operational states and carries an input unit. A display screen is carried by the lid and is controlled by the electronic unit to display graphic symbols and alphanumeric characters. The lid can be moved from an open position, allowing access to the input unit and allowing the screen to be seen, to a closed position. A mode indicator is carried by the base unit and displays various characters and symbols indicating different operational states of the computer. A viewing zone provided in the lid enables the mode indicator to be seen when the lid is closed.
