An input device, such as a stylus, can be operated to determine one or more conditions and select an appropriate operating mode. For example, a stylus can be attached to a host device when not in active use by a user. Attachment can be securely and releasably achieved with magnetic coupling. In such a configuration, the stylus can detect the attachment based on the presence and modification of magnetic fields. Based on such detection, the stylus can select an operating mode that allows power to be conserved when it is determined that certain components of the stylus need not be actively operated.
