Enable Hibernation
This item allows user to enable or disable the hibernation feature for OS. This option may be not effective
with some OS.
ACPI Sleep State
Use this item to define how the system suspends. In the default, S1 only (CPU Stop Clock), the suspend mode
is equivalent to a software power down. If you select S3 only (Suspend To RAM), the suspend mode is a
suspend to RAM - the system shuts down with the exception of a refresh current to the system memory.
Soft-Off by PWR-BTTN
Under ACPI (Advanced Configuration and Power management Interface) you can create a software power
down. In a software power down, the system can be resumed by Wake Up Alarms. This item lets you install
a software power down that is controlled by the normal power button on your system. If the item is set to
Instant-Off, then the power button causes a software power down. If the item is set to Delay 4 Sec. then you
have to hold the power button down for four seconds to cause a software power down.

This item sets the system status after restore on AC power loss.

Power Button
