Hi, thank you in advance for your excellent work on coreboot for chromebook computers, the UEFI version is working well, but now I need a modification to be able to manage ACPI, I need the computer to always be on, and what if it has Loss of current, when the power supply returns to the Computer, turn it on again without having to press the power button If this modification is possible or already exists, tell me the cost for the feature

You simply need to configure the coreboot build properly. When using menuconfig, go to "Mainboard" submenu and ensure the "System Power State after Failure" is "S0 Full on". The feature may also need additional support from the Super I/O (desktop) or Embedded Controller (laptop) side depending on what board are you using.
