Soft-Off by PWRBTN
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 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.
