consumption.
ACPI Suspend Type:
Two options are available: S1(POS) and S3(STR). The default setting is S3(STR).
Generally, ACPI has six states: System S0 state, S1, S2, S3, S4, S5. S1 and S3 states
are described below:
The S1(POS) State (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.
