ACPI Suspend Type:
Two options are available: S1(POS) and S3(STR). The default setting is S1(POS). Generally,
ACPI has six states: System S0 state, S1, S2, S3, S4, S5. S1 and S3 states are described
below:
The S1 (POS) State (POS means Power On Suspend):
While the system is in the S1 sleeping state, its behavior is as described below:
! The processor is not executing instructions. The processor's complex context is
maintained.
! Dynamic RAM context is maintained.
! Power Resources are in a state compatible with the system S1 state. All Power Resources
that supply a System Level reference of S0 are in the OFF state.
! Devices states are compatible with the current Power Resource states. Only devices
which solely reference Power Resources which are in the ON state for a given device state
can be in that device state. In all other cases, the device is in the D3 (off) state.
! Devices that are enabled to wake the system and that can do so from their current device
state can initiate a hardware event which transitions the system state to S0. This transition
causes the processor to continue execution where it left off.
