Provide a BIOS/EC dump if possible

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:
S/N: NXK0WEP002227021C52N00

Thanks in advance

Attached are 3 different bios versions extracted from the bios update. Don`t know which yours is so try all 3 ,it`s dependent on the power delivery hardware on the motherboard.

DMI
EA7000 - EA714F
EAA000 - EAA03F

Also attached are 3 macro scripts to copy the DMI from your backup to each bios, instructions for that are below -

This will only work if you have made a good backup !!!!!!

1. Install Tiny Hexer hex editor -> https://www.softpedia.com/get/Others/Miscellaneous/tiny-hexer.shtml

2. Make a new folder on your C: drive called DOLPHIN

3. Move or copy contents of extracted scripts.zip to DOLPHIN folder

4. Move or copy your bios backup and the 3 new bios to the DOLPHIN folder

5. Rename your backup bios to flipper.bin

6. Run each of the scripts one at a time, after each script has run close Tiny Hexer before moving onto the next one

Please leave feedback if it has worked for you, and also consider making a donation to badcaps or a dolphin sanctuary.

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 heat signature is BQ25700 section of the board. Nonetheless I do appreciate the effort. Thanks

The boardview/schematic doesn`t seem to be available at the moment but i may be wrong. You can post a request for them in the schematics forum https://www.badcaps.net/forum/troubl...-requests-only

What is the EC chip part number, can you make a backup

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.

You would need an EC programmer such as a SVOD4 or Vertyanov SUCCESSOR to make a backup from the keyboard connector

This is a different motherboard
