Hi [USER="242051"]kalilinux25[/USER]
I've researched how to rebuild the new BIOS firmware using a dump file and a stock firmware that can be obtained from the official Acer website by providing the laptop's serial number.
I've now built the file and will be testing it this evening.
Upon reviewing your file, I noticed several issues.
First, the header and footer differ significantly from those in my dump file.
Additionally, the DMI area and the Windows key are missing.
Could you let me know how you ended up with this...

Thank you, [USER="242051"]kalilinux25[/USER]
The laptop's behavior has changed.
Before the BIOS update, the keyboard would light up, and after a while, the laptop would restart with no display.
Now, when I connect the charger, a steady orange LED appears on the side. However, when I press the power button, the LED begins to blink slowly, flashing three times before shutting off, and nothing else happens. The keyboard remains dark.
Could this be due to a low battery? I woke up early this morning to test it and provide you with prompt feedback,...

Hi all,
I have an Acer Swift SF313-52-593S (MB: NB8511-PCB-MB-V5) that turns on.
All power rails are present, but the laptop continuously reboots with no image.
I suspect the BIOS is broken.
Could someone please help ?
The laptop serial number, SNID is:
033013465223
I attach the original bios I read from the XMC 25QH128AHIG chip with my CH341A programmer selecting the chip EON EN25Q128.
(I found somewhere in this forum that with the above selection read/write operation work perfectly).
Thank you....

Great, the new file works perfectly.
Service tag added at the first system initialization and then remained stored forever :-)
I no longer have the orange light when I press the power button, but a perfectly functioning laptop!
I just wanted to ask you for a clarification regarding when I couldn't open the file, for which you said I should have used the appropriate version for that BIOS.
I used 15.0.35.1951 which, looking at your screenshots, is exactly what you used to reconstruct my BIOS.
The original BIOS was built with 15.0.10.1432 which I couldn't...

The strange thing is that now, on the screens I am allowed to see without entering the admin password, the service tag seems to have changed.
Now it is 3KHQ3F3. Indeed, I am asked for the password where the displayed text is 3KHQ3F3-8FC8.
In my original file, the service tag was CJCH3J3 (at location 0x35D470). But opening the file you sent me, I cannot find that service tag anywhere.
I don't understand what is happening!!
Help me, please!!...

Thank you for the response.
I apologize for not mentioning the Service Tag again, but since I wrote it in the previous 2 posts, I thought it was no longer necessary.
Anyway, here it is again: CJCH3J3
The problem I have now is that I can't open the bin file with the Flash Image Tool (obviously, the version is the one appropriate for this purpose).
I get the following error:
Error 179: [Fit Actions] Failed to parse CSE region.
Error 10: [Ifwi Actions] Failed to decompose Region. Failed to decompose CSE data.
Error 18: [Ifwi Actions]...

Hello everyone.
I finally managed to extract the BIOS dump from the Winbond chip.
I analyzed the dump with the latest version of ME Analyzer generated from the Python sources and this is the result:

╚══════════════════╝
║ 2024.07.03-WinbondOnDell5420.bin (1/1) ║

Service tag: CJCH3J3
Thank you for your support, but I was wondering why there isn't a "universal" file for that type of motherboard that can be loaded and then set with the service tag afterwards.

Hi guys!!
I have a Dell Latitude 5420 laptop that showed an orange LED when I pressed the power button.
Removing the CMOS battery and short-circuiting the connector pins allowed the laptop to power up again, but reinserting the battery caused the orange LED to reappear when pressing the power button.
To save time, I bought a motherboard on AliExpress and replaced the entire unit, bringing the laptop back to life, of course.
Meanwhile, I purchased a CH341A v1.7 programmer and a brand new Winbond 25R256JVEN chip.
I tried using the programmer to identify...
