Abstract
A method and apparatus provides hardware-configured wake-up events for a computer operating system compliant with an advanced configuration and power interface (ACPI) protocol without requiring additional hardware. The method and apparatus includes generation of a system management interrupt (SMI) during normal ACPI working-to-sleep transition allowing a basic input-output system (BIOS) circuit to enable additional wake-up events independent of the computer operating system.
