I updated bios with lenovo update before backup, rollback was enabled, computrace are enabled too, admin password are clean, i mean ask for password at "F1" key press, just type enter and go to bios but i cant modify anything, i cant disable tmp and secureboot to install S.O., i dont know if this extra info helps in any way :c, with a few tries of files from here the password at "F1" screen was not "nothing to write" just press enter no more...Comment

Hi
I am in the exact same situation as you
Same board no. had a locked password. Tried reflashing several bioses here. The only one that worked was the one which worked for you, only the fact that even that bios was locked. I got no clue where to proceed from here.Comment

Hello,
I got a bios locked lenovo thinkpad yoga 11e 4th gen (model 20HS). I tried shorting the data and clock pins on the bios chip but that just ended up corrupting the bios as it wont post anymore. The bios is attached in the message. Can you guys help me potentially un-corrupt and unlock this bios file if possible? I am saying this because i have already exhausted my options trying out some of the bios files posted here for my board no. (DALI8KMB8DO: rev D) but they just wont post. Only the fans move.
PS cant seem to insert bios so i guess ill attach a link to a filesharing site hosting the file.

Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.
I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!
Attached is the bios dump in the state I received it... -
Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the... -
Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
