General ACPI Configuration
Suspend mode
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, you can choose to enter the Standby mode in S1 (POS) or S3
(STR) fashion through the setting of this field. 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 maintains all system contexts.
[S3 (STR)] The S3 sleep mode is a lower power state where the information 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.
