It's okay, I just wanted to know which SIO/EC you have. It seems to be a MEC1503H
It can be bypassed using this method, but it's a bit hard, you need to keep trying > Ec Pwd Bypass
At least it's better than the alternative method > Guide to transplant MEC1503 EC chip and EEPROM reprog...

Is it possible to damage the board when i try to use the bypass method?

[Maxpower3]

It doesn't work with MEC15XX/17 and NCPX chips (any board using the eSPI protocol).
And yes, it is possible to damage the motherboard, corrupt data, or lose all the PC's DMI information using this technique.

[Tix2]

So there is only way to change the MEC 1503 and then enter again DMI Info? I see that someone has used a USB Stick for this? Is this a fake or is it true?

try this one.

Hello.
With this dump i get fan at full speed + charger LED amber on. Small progress but progress

TRY FILE 1 IF NOT WORK TRY 2
ONLY MAIN

TRY FILE 1 IF NOT WORK TRY 2
ONLY MAIN

Bios dump from SMDFlea produces only amber light on charge port, nothing else.
Bios dumps from InfoDoc2 produces the same behavior like before, amber light on charge port and fan at full speed.

Now i'm 99.9% sure it is not bios problem.
