Low power mode for device power management

摘要

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 S 4 or S 5 . 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 S 4 or S 5 . 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 S 4 or S 5.
