*1: No power definition
Base on ACPI Spec. We define the no power as while we press the power button, the system cant leave S5 statusor none the PG signal send out from power supply.
*2: No display definition
Base on the digital IC three basic working conditions: working power, reset, Clock. We define the no display as
while system leave S5 status but cant get into S0 status.
Judge condition:
Check whether there are any voltage feedback control to turn off the power.
Check whether no CPU power will cause system cant leave S5 status.
If there are not any diagram match these condition, we should stop analyzing the schematic in power supply sending
out the PG signal. If yes, we should add the effected analysis into no power chapter.
Judge condition:
Check which power will cause no display.
Check which reset signal will cause no display.
Check which Clock signal will cause no display
Base on these three conditions to analyze the schematic and edit the no display chapter.
S5: Soft Off
S0: Working

For detail please refer the ACPI specification
