ABSTRACT:
An information handling system having PCI devices which comply with the Power Management Interface Specification have a low power mode that may be used to put Power Management Capability devices into a low power state when the information handling system enters into S4or S5. A firmware or software low power mode program, retained in non-volatile memory of the information handling system, recognizes when the information handling system is entering S4or S5. The low power mode program may clear the Power Management Event Enable or not in each of the Power Management Capable devices when the information handling system enters into S4or S5.
