The functionality is located in the BIOS of the LCE2mx on the register card "Chipset" -> "PCH-IO Configuration" -> "Restore AC Power Loss".
You can decide between the following three settings:
- Last state: will switch to the last state before the power loss.
- on: will switch on the LCE2mx after power loss. If you want, that the system starts up in every case, this option is the right one.
- off: will switch off the LCE2mx after power loss.
