X7DBU/X7DGU User's Manual 1-3 Special Features Recovery from AC Power Loss BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power- on state. See the Power Lost Control setting in the Advanced section (Boot Features) to change this setting. (*Note: Default: Last State).
Chapter 1: Introduction CPU Overheat LED and Control This feature is available when the user enables CPU overheat warning in the BIOS. This allows the user to define an overheat temperature. When this temperature reaches the pre-defined threshold, both the overheat fan and the warning LED will be activated. System Resource Alert This feature is available when used with Supero Doctor III in the Windows OS environment or used with Supero Doctor II in Linux.
X7DBU/X7DGU User's Manual Main Switch Override Mechanism When an ATX power supply is used, the power button can function as a system suspend button to make the system enter a SoftOff state. The monitor will be suspended and the hard drive will spin down. Pressing the power button again to "wake-up" the whole system. During the SoftOff state, the ATX power supply provides power to keep the required circuitry in the system "alive".
Chapter 1: Introduction It is strongly recommended that you use a high quality power supply that meets ATX power supply Specification 2.01 or above. It must also be SSI compliant (info at http://www.ssiforum.org/). Additionally, in areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.
