Wake from S5
When the RTC Date and Time is set in the BIOS, the computer will automatically wake
from an ACPI S5 state.
1.14.2.11
Power Supervisor
The Power Supervisor actively monitors the input voltages from the power supply and
protects the board and any attached peripherals from electrical overstress and possible
physical damage.
The Power Supervisor will activate if it detects the power supply
voltage rails have deviated outside the current ATX power supply specification and safe
operating levels.
If the Power Supervisor detects an out of spec voltage, the following will happen:
1.
The board will be powered down immediately to protect circuits from electrical
overstress and possible physical damage.
2.
A red warning LED on the board will activate as a visual cue.
3.
During the next power on, a message will be
displayed on the screen to notify the
user that the power supply voltage rails have deviated outside the current ATX
power supply specification and safe operating levels.
4.
A message will be added to the BIOS Event Log for each event that takes place
until the BIOS Event Log is cleared.
