1-3 PC Health Monitoring
This section describes the PC health monitoring features of the PDSBA-Q+/PDS-
BA+/PDSBA/PDSBE. The motherboard has an onboard System Hardware Monitor
chip that supports PC health monitoring.
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 Con-
trol setting in the BIOS chapter of this manual to change this setting. The default
setting is Always OFF.
Onboard Voltage Monitoring
The onboard voltage monitor will scan the following voltages continuously for the
CPU Core, +1.8V, +3.3V, +3.3V standby, +5V, Vbat and ±12V. 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 by using SD III.
Fan Status Monitor with Software
The PC health monitor can check the RPM status of the cooling fans via Supero
Doctor III.
CPU Overheat 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
temperature reaches the pre-defi ned 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 speed will be decreased.
