KPCXXXX-J Motherboard and BIOS setting

Restore AC Power Loss
This setting specifies whether your system will reboot after a power failure or interrupt occurs. Available settings are:
[Power Off] Leaves the computer in the power off state
[Powr On] Leaves the computer in the power on state
[Last State] Restore the system to the previous status before power failure or interrupt occured.
Deep S5
The setting enables/disables the Deep S5 power saving mode. Deep S5 is almost the same as G3 Mechanical Off, except that the PSU still supplies power at a minimum to the power button to allow return S0. A full reboot is required. No previous content is retained. Other components may remain powered so the computer can "wake" on input from the keyboard, clock, modem, LAN, or USB device.
