Abstract
Before a register provided exclusively for an Advanced Configuration and Power Interface (ACPI) is set, a System Management Interrupt (SMI) is issued to a Central Processing Unit (CPU). A System Management-Basic Input Output System (SM-BIOS) performs the power management of a computer system. Values representing a wakeup factor of the system and a power management event are set in the register, and an Operating System Directed Power Management System (OSPM) is informed of a Power Management Event (PME). When the values are set in the register, an SMI is issued to the CPU, and the SM-BIOS performs the power management of the computer system.
