Lenovo ideapad 5-14ALC05 BIOS

Hello, I have a problem with removing the password from the BIOS dump. I bought a laptop with password protected BIOS (ideapad 5-14ALC05 Laptop - Type 82LM - 82LM008VCK) board FLMA0 LA-J701P Rev. 2.0 with Ryzen 5 5500U. Using the CH341A programmer, I made a bios dump from the Winbond W74M12JWSIQ bios chip (attached). But now I'm stuck on how to find the bios password and how to remove it. Can anyone help me with the removal or upload a clean bios for this laptop model?
Thank you in advance for any help.

Can you post the laptop serial number. Comparing your backup with the one at post #2 they are very different,both are supposed to be Type 82LM. Is there another bios chip on the board ?

It is possible because ideapad 5 has 3 versions of motherboard rev.01 rev.02 and rev.03. The first board had a regular BIOS chip W25Q128JWSIQ, my rev.02 board has a chip variant marked W74M12JWSIQ. It's basically the same chip with some extra protection (which doesn't have to be used, as in this case). The BIOS uploaded above in the thread is probably from the version of the board that has the original W25Q128JWSIQ chip. The SN of my laptop is MP1ZRCVR.

Sorry for the late response, but I didn't have time to test. I flashed the BIOS you uploaded. The password was removed, the system also seems to be working, but I want to ask. Is there something I'm missing in the bios, or do I have all the necessary information there?

Hi all,

Can someone help me fix my bios?
Not sure if the bios is the problem but is the easiest to check.
Symptom is black screen with backlight on

Thanks.

Mine is 14ALC05 not 15ALC05. Same motherboard?

Also this file and all files on this thread are very different from my backup.

Are these files suitable for flashing directly to the chip by using external programmer or are only used for software flash?

it's not good, you must have the same result.. remove the bios chip from the board before reading or writing, if you don't have anything to remove the chip, stick wires between the programmer and the chip.. watch a video here.. use one of these programs..

Re: Lenovo ideapad 5 14alc05

Sorry, guys.
Board has short circuit in 1,8 power line.
It's not a bios.
One of the indutor became too hot. It has strange voltage: 0,846 from one side and 0,766 from other.
Heat pipes hot too.
