    Hello everyone,

    I had the problem 2 days ago when updating the bios that it froze. Even after a good 5 hours the status has not progressed a bit. After forced shutdown and restart everything stayed black and nothing reacted. Thanks to this forum, I read out the bios with the CH341A and saved the non-functioning ones first. I then uploaded the file from the forum to the bios chip. PC and Windows starts but Win11 complains about the missing key. In the bios the information about serial number, key and so on is missing. I also have a photo of the information page of the bios before I tried the update.

    Now the bios version E8CN41WW is installed and working

    Can someone help me to get the information into the bios file, it would also be great if the Preinstalled OS license would be possible.

    Many thanks in advance

    The problem is that when I start up, I get an error in MS-DOS about the newly installed CPU and other times a blue screen appears, and I have the latest BIOS installed from the Lenovo website, but the PC is unstable.

    I can give you the file from the Lenovo homepage, but it doesn't have the DMI since you don't have the original file.

    Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
    by jendkkd jeje
    So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

    I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

    Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
    by Wahaz
    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....

    Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
    by grimacelord
    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...
