Hi, i hope you can help me.

Model Name: Legion 5 Pro 16ACH6H
Serial: PF2T4BXS
MainBoard: NM-D562 Rev. 2.0

Specs are AMD R5 5600H, Nvidia RTX 3060

The Problem:
i forgot the bios password.

i read the bios chip(which i hope it is) winbond 25Q16JWNIQ with a CH341 Programmer. i used an adapter to read it at 1.8V (foundin the internet that it was 1.8V and not 3.3V)
i have a 2MB bin file .Please tell me if i did any mistake or if i dumped the bios file correctly.
i used NeoProgrammer 2.2.0.10. when i hit "Detect" it gives me 2 options: one of them is the W25Q16FW with 16Mbits as Size which is 1.8V, the other one is something else with 1.2V.
in Size i have this number: 2097152
i hope im not wrong.

Thank You.

the bios must have 16Mb, look for a bios chip.

After speaking with the person who flashed it, they told me that the backup was taken from the chip marked in the photo, which is why it's only 2MB, and then they wrote the main firmware there, which is 16MB.

The other chip, where I have the programmer, has the 16MB BIOS as I saw when making the backup, which I am attaching.

That 2MB chip looks like it could be the vBios

Any new suggestions?

[Aníbal Barnés Asenjo]

I think I will also need the EC BIOS.

I've spoken with the technical service, and they have sent me the original BIOS backup.

With this firmware, nothing powers on, only the power button.

With this firmware, the computer heats up the CPU and GPU, the fans start, and the keyboard lights up, but there is no video signal...

I am attaching a backup of my BIOS, but I cannot guarantee that it is the original one since a previous technical service flashed the BIOS for me
