A portable computer. The computer includes a base, a display member, and an arm assembly coupling the display member to the base. The arm assembly includes a pair of spaced arm portions and a rigid connecting portion extending between the arm portions. The arm portions each have a first end pivotally coupled to the base edge for movement of the arm assembly between a closed position with the arm portion substantially parallel to the base and an open position with the arm portion oriented at an angle relative to the base, and a second end pivotally coupled to the display edge for pivotal movement of the display member relative to the arm portion to move the display member between a plurality of positions relative to the arm member.
