Abstract: An auxiliary device for charging and facilitating hardware shutdown/reset of an electronic device includes a charge transmitter configured to transmit electric power signals, an input user interface for receiving a user input, a wireless control signal transmitter configured to transmit wireless control signals, and a microcontroller unit (MCU). The MC is configured to: determine a user instruction based on the user input; enable the wireless control signal transmitter to transmit a wireless control signal in response to the user instruction; and control the charge transmitter to selectively transmit the electric power signals according to a timing sequence selected based on the user instruction. In some embodiments, the input user interface and the wireless control signal transmitter are a same device (e.g., a slidable magnet).

Abstract: A system includes an electronic device and an auxiliary device for charging the electronic device and facilitating hardware shutdown/reset of the electronic device when the electronic device is being charged. The system includes an input user interface (e.g., on the auxiliary device or the electronic device) configured to receive a user input for hardware shutdown/reset of the electronic device. The electronic device includes a switch between a battery and a system load, a control circuit configured to open the switch to disconnect the battery and the system load, and a charging interface configured to receive electric power signals from the auxiliary device to power the control circuit, such that hardware shutdown/reset of the electronic device is performed when the electronic device is being charged, thereby preventing unintentional hardware shutdown/reset during normal use. In some embodiments, wireless control signals are used to initiate hardware shutdown/reset on the electronic device.

Abstract: An electronic device includes a battery, a system load, a switch in an electrical connection path between the battery and the system load, a non-contact sensor configured to detect a wireless control signal associated with an instruction, a control circuit configured to open the switch to disconnect the battery and the system load in response to the detected wireless control signal, and a charging interface configured to receive electric power from an external source, where the control circuit and the non-contact sensor are powered through the charging interface rather than the battery.
