ACPI Aware O/S (Yes)
This item supports ACPI (Advanced Configuration and Power management Interface).Use this item to enable or
disable the ACPI feature.
ACPI Suspend Type (S3 (STR))
Use this item to define how your system suspends. In the default, S1 (POS), the suspend mode is equivalent to
a software power down. If you select S3 (STR), the suspend mode is suspend to RAM, i.e., the system shuts
down with the exception of a refresh current to the system memory.
Deep Power Off Mode (Enabled)
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.
Power On by RTC Alarm (Disabled)
The system can be turned off with a software command. If you enable this item, the system can automatically
resume at a fixed time based on the system’s RTC (realtime clock). Use the items below this one to set the date
and time of the wake-up alarm. You must use an ATX power supply in order to use this feature.
Power On by PCIE/PCI Devices (Disabled)
The system can be turned off with a software command. If you enable this item, the system can automatically
resume if there is an incoming call on the PCIE LAN card. You must use an ATX power supply in order to use
this feature. Use this item to do wake-up action if inserting the PCIE card.
