Abstract

Abstract A portable computer comprising a main computer body with an embedded keyboard, and a display unit. The computer body is electrically connected with the display unit and the display includes a controllably collapsible and erectable display unit support for adjusting the position of the display unit with respect to the main computer body, whereby the display unit can be positioned at a comfortable and ergonomically safe position and the portable computer including the support can be folded compactly for storage or transportation. In another embodiment, the display unit is detachable from the main computer body, and is suspended by an external structurally stable object by suspension, whereby the display unit can be positioned at a comfortable and ergonomically safe position and no support needs to be transported or stored with the computer, thereby saving weight and space.
