used to set a number of power management related functions.

Suspend Mode
The Suspend Mode field has three selectable options.
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.
Auto
When the Suspend Mode is set to Auto, the operating system will control the power state.
