Abstract

A portable information handling system includes a variable torque hinge that increases torque to resist hinge rotation when the information handling system housing rotates to a writing position, such as rotation to a range of between 300 and 350 degrees. In one embodiment, a sequential hinge rotates in the writing range about one axle that has increased friction in the desired writing range generated by a cam having a variable surface area and depth to work a variable friction between a friction structure and axle end cap.
