own style of computer use.

Disabled

and

1~15

(minutes)

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 context.

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 OS to select S1 or S3.
