Hello everyone,
I am looking for a clean EC dump (1MB / 8Mb) for my laptop. Unfortunately, I erased the original chip by mistake without making a proper backup.
Here are the exact specifications of my laptop:

• Laptop Model: Acer Swift 5 SF514-55TA
• Motherboard Model: NB2629_PCB_MB_V3
• EC Chip: Winbond W25Q80DV (8M-bit / 1MB)

If anyone has a working dump for this specific board, please share it.
Thank you very much for your help!

Hello, I am French and my English is a bit rough.
Thank you for your reply SMD FLEA. As suggested on your website, I tried to fix my BIOS issue on my own with my XM25QH128A chip. Unfortunately, I can no longer make a backup because I completely erased it using NeoProgrammer. I thought the BIOS file from the Acer website would be enough, but after researching on several sites, I learned that the BIOS must contain the ME region, the serial number, and other information that I unfortunately deleted during my first attempt (I clicked "Erase" instead of reading and saving it).
I cannot solve this without your help. :-( :-( What exactly do I need to do so you can kindly help me get a working file that I can flash onto my corrupted BIOS?

Update with my exact laptop specs for rebuild:

• Laptop Model: Acer Swift 5 SF514-55TA-53TH
• Product Number: NX.A6SEF.003
• Serial Number (S/N): NXA6SEF00304706E6A2N00
• Motherboard: NB2629_PCB_MB_V3
• CPU: Intel Core i5-1135G7 (Tiger Lake)
• BIOS Chip: XMC XM25QH128A (16MB)

Unfortunately, my original dump is completely lost (accidental erase). Please help me provide a Working Clean ME BIOS dump matching this configuration. Thank you so much!

Try this bios.

Thank you so much, SMDFlea! As soon as I can download it (for now, the website is still asking me to pay to access the file), I will immediately try the file you kindly sent me. I will come back here to let you know if it works. Thank you for this incredibly valuable help!!

Thank you for the BIOS file, SMDfléa. However, the computer is still blinking 3 or 4 times in blue, and then... nothing, it still won't boot. Is it possible that the issue is coming from the ITE chip, and could it be reprogrammed? Where could I find a firmware/dump for it? Thank you for your help!

[Philou0023]

Thank you for the BIOS file, SMDfléa. I flashed it successfully, but the issue remains exactly the same: the computer still blinks 3 or 4 times in blue and won't boot.
I have checked the voltage rails under power:

• The two 1R0 coils are getting 3.3V and 5.0V (perfectly stable).
• The R22 coils (CPU VCore) stay at 0V.
• Resistance to ground on the R22 coils is 32.5 Ohms (so no short circuit on the CPU line).

The board seems stuck just before enabling the CPU power sequence. Could it be an issue with the ME region or a bad communication with this specific BIOS dump? Or do you think the ITE IT5571VG-128 chip itself is dead?
Thank you for your help

[Philou0023]

I programmed the BIOS chip directly on the board using a SOIC8 clip (the chip was not desoldered

Should I move this post to the hardware/electronics repair section now, since we seem to be heading toward an electronic component issue? Or is it better to keep the discussion here? Thank you for your guidance!

[peste]

yes, move the discussion to the main forum if you no longer need the bios...
