An improved hinge mechanism for use with a portable computing device is disclosed. According to one embodiment, a hinge mechanism includes a first gear and a first deformable braking mechanism that is coupled to the first gear. The first deformable braking mechanism is substantially axially aligned with the first gear along a first axis. The hinge mechanism also includes a second gear that engages the first gear during rotation of the first gear, as well as a second braking mechanism. The second braking mechanism is arranged to be substantially axially aligned with the second gear along a second axis. The second braking mechanism contacts the first deformable braking mechanism to cause the first deformable braking mechanism to deform during rotation of the first gear. Finally, the hinge mechanism includes a linking mechanism that allows a constant distance to be maintained between the first axis and the second axis.
