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.

A modular electronic device system includes an electronic device and a cover for the device that allows the device to be mechanically and electrically mounted to a stand or device adapter on the rear side of the cover. The cover or device adapter can be connectable to modularly attachable and removable accessory devices and can provide electrical ports for powering and operating the accessory devices. While mounted to a stand, power and data communications can be provided to the electronic device, cover, and accessory devices from the stand or an external source. The modular components of the system can be interchangeable to allow the system to be adapted to many different settings and use cases based on the types of components included as the accessory devices and based on the number of accessory devices used.
