Device power controller

A method, comprising:

• receiving a wakeup sleep duration from an agent executing on a motherboard of a terminal;
• setting a timer to the wakeup sleep duration;
• monitoring a core of the motherboard for an indication that the core is in a shutdown state;
• when the indication is identified, causing power from a power supply unit (PSU) to be cut to the motherboard of the terminal;
• monitoring the timer until it expires;
• and
• causing power from the PSU to be restored to the motherboard of the terminal when the timer expires, the core restores operation of applications and peripheral devices of the terminal.

A method, comprising:

• identifying a wakeup sleep duration associated with powering down a transaction terminal for a defined period of time;
• sending a firmware instruction with the wakeup sleep duration to firmware of a miscellaneous control board or a power supply unit (PSU) control board of the transaction terminal;
• initiating a shutdown or power down sequence of operations on a core of the transaction terminal;
• and
• iterating to the identifying once the core is rebooted and active on the transaction terminal following power being restored by the firmware after expiration of the wakeup sleep duration.

A system, comprising:

• a transaction terminal including a motherboard with a core, peripheral devices, and a power supply unit (PSU);
• a miscellaneous control board or PSU control board connected to the motherboard and the PSU;
• the miscellaneous control board or PSU control board including a processor and a non-transitory computer-readable storage medium comprising executable instructions;
• the executable instructions when executed by the processor cause the processor to perform operations comprising:
• receiving a wakeup sleep duration from an agent executing on the motherboard;
• setting a timer to the wakeup sleep duration;
• monitoring the core for an indication that the core has shutdown applications and the peripheral devices;
• when the indication is identified, causing power from the PSU to be cut to the motherboard;
• monitoring the timer until it expires;
• and
• causing power from the PSU to be restored to the motherboard when the timer expires, the core restores operation of the applications and the peripheral devices.
