Abstract

A rechargeable computing device including a battery, a processor, a power receiver, a reset switch, and a circuit for receiving a reset signal may receive the reset signal via a power source. The processor may be configured to be reset in response to actuation of the reset switch. The power receiver may be configured to receive a wireless power transmission from a remote charging apparatus and charge the battery using power captured from the wireless power transmission. The reset switch may be coupled to the processor and to the circuit for receiving a reset signal. The circuit for receiving a reset signal may be configured to activate the reset switch to reset the processor in response to detecting a reset signal encoded within a wireless power transmission. In some embodiments, the circuit for receiving a reset signal may be configured to receive the signal from a wired power input.
