Abstract
Computer system powered-off state auxiliary power rail control. At least some of the illustrative embodiments are systems configured to have: a first powered-off state in which the main output power signal is deactivated within the power supply and the auxiliary power output signal is active and coupled to an auxiliary power rail of the printed circuit board; and a second powered-off state in which the main power output signal is deactivated and the auxiliary power output signal is active and decoupled from the auxiliary power rail of the printed circuit board.
