** What’s the definition of former state at AC power failure?
1) The previous state is “ON”
2) The previous state is “OFF”
Logical Device A, CR E4h
To ensure that VCC does not fall faster than VSB in various ATX Power Supplies, the W83627DHG
adds the option of “user define mode” for the pre-defined state before AC power failure. BIOS can set
the pre-defined state to be “On” or “Off”. According to this setting, the system chooses the state after
the AC power recovery.
