These are the 2 bios file original backup

[pyanystul]

I have a problem with 15ACH6 laptop:
First time the laptop worked but had bios password.
The laptop has 2 BIOS cips (WINBOND) I download the bios from lenovo website (8Mb), I delete and write new bios to the first winbond cip (25Q16..) no change, laptop worked but still had bios pass.
I delete 2th winbond cip (74M12...) and I rewrite back with the oiginal bios file extracte before (120Kb), I didn't make any chages to the original bin file, I only read the cip, I did an backup then I delete the cip and write back the same bios file from previous backup.
Now the laptop has black screen....

I looked at these bios in the editor, my BIOS starts differently, in my dump it starts with the multicontroller firmware, but there it’s different. The second thing that confused me is that I don’t understand how to figure out which version of these four I have. I ask for your help

Just try all 4.

I just thought it was okay not to indicate it,

No, it's not "okay", the rules are clear:
You MUST:

Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules. Not as a picture, part of the file name and so on.
Name your thread with make, full model numbers and request

I changed it to the full name of the model, I just thought it was okay not to indicate it, because there are problems with Lenevo Ideapad 3 15ACH6 in this thread

[Vesko356]

Read the rules - you MUST add make and FULL model name to your request!
