1-3 PC Health Monitoring
This section describes the PC health monitoring features of the PDSMi-LN4. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitoring
The onboard voltage monitor will scan the following voltages continuously: CPU
Cores, Chipset Voltage, Memory Voltage , +3.3V, +5V, +5V Standby, +12V, and
−12V (via SuperO Doctor III). Once a voltage becomes unstable, it will give a warning
or send an error message to the screen. Users can adjust the voltage thresholds
to defi ne the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by Thermal Management via BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature. When this tem-
perature reaches the threshold, the CPU thermal trip feature will be activated and it
will send a signal to the Speaker LED and, at the same time, the CPU will slow down.
It will also activate the alarm if a fan failure occurs.

Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in the suspend mode. When the user presses any key,
the CPU will wake-up and the LED will automatically stop blinking and stay on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, this keyboard will function
like a normal keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will enter into
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Pressing the power button again will cause the whole system to wake-up. During the
