Abstract
Abstract A display cover is coupled to a portable computer by one of a variety of double-pivot hinges. Such arrangements permit the cover to be folded flush against the back of the computer, providing the screen protection benefits of a cover without the usually-attendant increase in computer "footprint." The preferred cover includes a window that permits a portion of the display to be viewed even when the cover is closed. By such an arrangement, alert or status messages can be conveyed to the user without requiring that the cover be opened. In some embodiments, the user can respond to visual or other alert messages, again without opening the cover.
