HP Chromebook 11A G6 EE turns on upon lid open or power cable plugged in even after full shutdown.

Good morning,

My Chromebook HP 11A G6 turns on upon opening the laptop lid, even if I've shut it down totally with poweroff command and I haven't pressed the power on button. It's also happening when plugging in the power cable.

How to turn it off?

Easy answer, you can't. This happens on my school Chromebook when I log in to my school account on Chrome OS and I face that all the time. This is not a problem to me and you can't change what is happening with your Chromebook.

Meaning the lid as well as plugging in the cable sends the same signal as power button and Coreboot couldn't recognize the difference?

this is standard Chromebook behavior. You can build coreboot and disable the lid opening as a wake source, but to disable it as a power-on source, you will need to build custom EC-RW firmware (same with booting on external power detect)

how to install built and tested ROM file onto the board with correct HWID and VPD?

[MrChromebox]

I'm not sure what you mean "install built and tested ROM file"

[GamePlayer-8]

I have the ROM file with modified config, but I don't know how to use the firmware script in order to install ROM onto the board.

you can flash just the COREBOOT region using --fmap -i COREBOOT and then the VPD and HWID don't get touched
