A hinge mechanism for rotatable component attachment is described. In at least some implementations, the hinge mechanism enables a support component to be adjustably attached to an apparatus, such as a computing device. For example, the hinge mechanism can be employed to rotatably attach a kickstand to a mobile computing device. The kickstand can be rotated via the hinge mechanism to various positions to provide support for different orientations of the computing device. For example, the kickstand can be positioned to support the computing device in a typing orientation such that input can be provided via an associated input device. As another example, the kickstand can be positioned to enable viewing and/or interaction with the computing device, such as in a portrait viewing orientation.
