Abstract
Systems and methods are disclosed for preventing a display component of a portable information handling system from opening when in an upside down position. The portable information handling system may include a base component coupled to the display component by a gravity lockout hinge. The gravity lockout hinge may include a shaft, a bearing channel having a bearing channel surface opposite the shaft, and a movable bearing disposed in the bearing channel. The gravity lockout hinge may, when the portable information handling system is in an upside down position and a gravitational force is exerted on the display component, exert a first frictional torque on the shaft that may cause the movable bearing to contact the shaft and the bearing channel surface, and exert a second frictional torque on the shaft that may prevent an angular position of the display component relative to the base component from being changed.
