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?

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?
 
Please repair my bios. Not turning on, musical tone after pressing power button. Thank you in advance
