that's the goal of system management mode and things alike. I suggest you document about ACPI (advanced Control Power Interface) and APM (advanced Power Management) to figure out how it better works.

as Pype already mentioned, it's in ACPI stuff. But, ACPI can't make your processor just do what it wants to without any control from you. They use SMM, which you can also use (although I don't know how) and they use plain ports and/or memory mapped stuff. However, most of it is system specific.

Use the ACPI interfaces for the easiest way.
