1. An electronic appliance, comprising:

  • a power supply;

    an electronic circuit board coupled with the power supply; and

    a sequencer engine coupled with the electronic circuit board, the sequencer engine to sequentially enable voltage regulator controllers on the electronic circuit board during a power up based at least in part on settings stored in non-volatile memory, the sequencer engine to retrieve delay times for a future power state change, and the sequencer engine to prevent the power supply from changing states until voltage regulator controller outputs are stable.
