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.
