Suspend Mode [Auto]
Allows you to select the Advanced Configuration and Power Interface (ACPI) state to be used
for system suspend.
[S1(POS) Only] - Enables the system to enter the ACPI S1 (Power on Suspend) sleep state.
In S1 sleep state, the system appears suspended and stays in a low power
mode. The system can be resumed at any time.

In S3 sleep state, the system appears to be off and consumes less power than in

to its working state exactly where it was left off.
