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.

Abstract
In some embodiments, a method, apparatus and system for enabling and disabling voltage regulator controllers are generally presented. In this regard, a sequencer agent is introduced to selectively enable or disable the outputs of voltage regulator controllers in an electronic appliance based at least in part on settings stored in non-volatile memory. Other embodiments are discussed and claimed.
