The Suspend Mode field has three selectable options.
S1(POS) S1(POS) S1(POS) 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(STR) S3(STR) 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.
