Special Features
C.3.1
Recovery from AC Power Loss
The BIOS setup can be configured to allow the system, whenever AC power is lost,
• to remain off (power switch must be pressed to turn system back on) or
• return to a power-on state automatically when power is restored.
This setting can be accessed in the Advanced section of the Appendix B, “BIOS
Setup Utility”. The system default is “
Last State
”.
C.3.2
PC Health Monitoring
The following sections describe the PC health monitoring features of the mother-
board. All have an onboard System Hardware Monitor chip that supports PC health
monitoring. An onboard voltage monitor will scan these onboard voltages continu-
ously: CPU cores, +1.8V, +3.3V, +5V, +12V, +3.3V Standby, +5V Standby, VBAT,
Memory, Chipset Voltages. 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
define the sensitivity of the voltage monitor.
C.3.2.1 Fan Status Monitor
The PC health monitor utility can be used to check the RPM status of cooling fans.
The onboard CPU and chassis fans are controlled by Thermal Management via
BIOS.
C.3.2.2 Environmental Temperature Control
The thermal-control sensor monitors CPU temperature in real time and will activate
the thermal fan when CPU temperature exceeds a user-defined threshold. Overheat
circuitry operates independently from the CPU, and can continue to monitor over-
heat conditions even when the CPU is in sleep mode.
Once the thermal sensor detects a CPU temperature that is above the set threshold, it
automatically turns on the thermal control fan to prevent overheat damage to the
CPU. In addition, onboard chassis thermal circuitry can monitor overall system tem-
