** What’s the definition of last state when AC power failure?
1) Last state is “ON”
2) Last state is “OFF”
To prevent that VCC goes down faster than VSB in various ATX Power Supply.
W83627EHF/EF,W83627EHG/EG add the “user define mode” option for AC power loss pre-state.
BIOS can set the pre-state that is “On” or “Off” state, because the status of AC power resume
depends on it.
