From the software point of view, this state is functionally the same as the S2 state. The operational
difference can be that some Power Resources that could be left ON in the S2 state might not be available
to the S3 state. As such, additional devices can be required to be in logically lower D0, D1, D2, or D3
state for S3 than S2. Similarly, some device wake events can function in S2 but not S3.
Because the processor context can be lost while in the S3 state, the transition to the S3 state requires that
the operating software flush all dirty cache to DRAM.
Above information for system S1 were refer to ACPI Specification Rev. 1.0.
