  2. *1:No power definition Base on ACPI Spec. We define the no power as while we press the power button, the system can’t leave S5 status or none the PG signal send out from power supply. Judge condition: • Check whether there are any voltage feedback control to turn off the power. • Check whether no CPU power will cause system can’t 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. *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 can’t get into S0 status. 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 Keyword: For detail please refer the ACPI specification
