Sleep State
This item specifies the power saving modes for ACPI function. Options are:
S1/POS
The S1 sleep mode is a low power state. In this state, no
system context is lost (CPU or chipset) and hardware main
tains all system context.
S3/STR
The S3 sleep mode is a lower power state where the infor
mation of system configuration and open applications/files
is saved to main memory that remains powered while most
other hardware components turn off to save energy. The
information stored in memory will be used to restore the
system when a “wake up” event occurs.
Auto
The system will decide when to enter S1 or S3 state.
