I'm still having the same error. It reaches 20V with 0.05A of consumption, but it doesn't turn on. I have the orange charging light, and the power light blinks three times. Could it be EC programming? Do you have a dump?

try more bios new and check hardware

I've already tried the BIOS in this thread, and I've also tried the rebuilt one, and it's still exactly the same. The board doesn't go past S5. I checked the hardware, and I suspect the EC BIOS. Is there EC firmware for this board?
