ABSTRACT:
A power consumption manager and a power manager sequencer coordinate transition of information handling system components between active and inactive states to manage information handling system power consumption. The power manager transitions components to an inactive state upon a determination of inactivity and then shuts down, for instance by operating as a module in the BIOS. Activation of an I/O device, such as the power switch, restores the power manager to an active state to allow recovery of the information handling system to an operational status. The power manager sequencer detects activation of the I/O device to restore selected components to an active state substantially simultaneous with the power manager so that the selected components have power to accept recovery instructions from the power manager. For instance, a network interface controller receives power to recover from an inactive state before the BIOS sends a PCI bus reset command.
