ACPI Suspend Type
Setting Description
S1(POS) S1/Power On Suspend (POS) is a low power state. In this state,
no system context (CPU or chipset) is lost and hardware
maintains all system contexts.
S3(STR) S3/Suspend To RAM (STR) is a power-down state. In this state,
power is supplied only to essential components such as main
memory and wakeup-capable devices. The system context is
saved to main memory, and context is restored from the
memory when a "wakeup" event occurs.
S1 & S3 Depends on the OS to select S1 or S3.

Windows XP will override this option.
