A computing device may include a base member, a display member, a first hinge, a second hinge, a stop, and a locking arm. The first hinge may be attached to the base member to rotate the base member and the display member relative to each other about a first pivotal axis of rotation. A second hinge may be attached between the first hinge and the display member to rotate the base member and the display member relative to each other about a second pivotal axis of rotation to transition the computing device between a laptop mode and a tablet mode. The stop may be in the first hinge. The locking arm may be to engage the stop when the computing device is in the tablet mode to limit rotation of the base member and the display member relative to each other about the first pivotal axis.
