1-4 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 Advanced BIOS Setup section to change this setting. The default setting is Last State.
1-5 PC Health Monitoring
This section describes the PC health monitoring features of the X7DWE. All have an onboard System Hardware Monitor chip that supports PC health monitoring. An onboard voltage monitor will scan these onboard voltages continuously: CPU Core, Chipset Voltage, Memory Voltage, +1.8V, +5V, +3.3V, +3.3V Standby, +5V Standby, +12V, −12V and VBatt. Once a voltage becomes unstable, a warning is given or an error message is sent to the screen. Users can adjust the voltage thresholds to defi ne the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
The PC health monitor can check the RPM status of the cooling fans. The onboard CPU and chassis fans are controlled by Thermal Management via BIOS (under Hardware Monitoring in the Advanced Setting).
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn on the thermal control fan whenever the CPU temperature exceeds a
CPU Fan Auto-Off in Sleep Mode
The CPU fan becomes active when the power is turned on. It continues to operate when the system enters the Standby mode. When in the sleep mode, the CPU will not run at full power, thereby generating less heat.
