Abstract: An electronic apparatus includes a base subassembly and a display subassembly. A hinge is rotatably coupled to the base subassembly and the display subassembly. The hinge allows the base subassembly and the display subassembly to rotate about an operating axis to change a rotational orientation of the display subassembly relative to the base subassembly. An elevation mechanism is operatively coupled to the hinge. The elevation mechanism includes a support tray disposed in the base subassembly that holds the mechanical elements. The elevation mechanism is responsive to torque that changes the rotational orientation of the display subassembly such that the elevation mechanism lifts the support tray when the display subassembly is moved to an upright position and lowers the support tray when the display subassembly is moved to a closed position.
