Unfortunately i will not be able to get the FW fro EC. It is ITE IT5571VG-128 a BGA chip. I do not have any programmer adaper for this form-factor and without schematic - i will post request as you suggested i do not have any reference points to try....

Thank You!
I am still not on the end of the work, but I do have a new behavior from the laptop. With bios files that you provided laptop after start now powers on the backlight - resets four times and goes down. For my surprise with all off them. For in depth comparison and to eradicate potential of issues with the original DMI sectors i did also checked with blank files. So my assumption there is still some physical issue with the board itself. The usual check with caps-lock does suggest we are still a no-post. I will need to search for a boardview as the only suspicious part with unusual...

Hi All. I do have an exact same motherboard on bench . I do suspect the bios, as I cannot see any other issue on the PCB. I have power and there is an initial fan spin and i do take those as good signs as not to be a dead CPU - no shorts on VRMs also a good sign. I do attach a bios dump from my machine. Hope someone will be able to determine if this is the issue. I tried to get official clean bios, but the fd's from Acer are beyond my knowledge in this department.

Also as per additional info:
