US 12,737,019 B2 · Initiating recovery of an electronic device using a power reset pattern

Abstract

Techniques are described herein that are capable of initiating recovery of an electronic device using a power reset pattern. In a first example implementation, a determination is made that an electronic device is in a non-operational state. A power supply control signal is generated. The electronic device is caused to initiate a recovery process using a power reset pattern by providing the power supply control signal to the power supply via a power line. The recovery process changes the electronic device from the non-operational state to an operational state. In a second example implementation, a power reset pattern is received via a power line from a power supply. A determination is made that the power reset pattern is an instruction to initiate a recovery process. An electronic device is changed from a non-operational state to an operational state by initiating the recovery process.

Dependent claims

An electronic device comprising:

a processor system;
and
a memory that stores computer-executable instructions that are executable by the processor system to at least:
receive a power reset pattern via a power line from a power supply associated with the electronic device, the power reset pattern defined by a plurality of power pulses having a plurality of respective durations;
determine that the power reset pattern is an instruction to initiate a recovery process, wherein the recovery process is configured to change the electronic device from a non-operational state to an operational state;
and
in response to a determination that the power reset pattern is the instruction to initiate the recovery process, change the electronic device from the non-operational state to the operational state by initiating the recovery process.

A method implemented by a computing system, the method comprising:

detecting that an electronic device is in a non-operational state;
generating a power supply control signal, which is configured to control timing of on states and off states of a power supply associated with the electronic device in a manner that results in a plurality of power pulses having a plurality of respective durations;
and
causing the electronic device to initiate a recovery process, which changes the electronic device from the non-operational state to an operational state, using a power reset pattern, which is defined by the plurality of power pulses having the plurality of respective durations, by providing the power supply control signal to the power supply via a power line.
