    Lenovo IdeaPad S540-13API (NM-C581 GS341) bios files

    Hi guys,

    A friend tried to update the bios on this lenovo and it never turned on again.

    I can find and flash the large chip (UC3, 64mbit) but power led still blinks with no image - I get fan spin and kbd light. There is another chip (UT4, 8mbit) for which I can't find the .bin file and I am not educated enough to decrypt the bios from the website (I attached it).

    Please help!

    BR,
    george

      i'm not sure this bios fit with your board, you can try this but make sure backup your bios first. File was tested by myself, next time if you want to try extract bios from lenovo you can use innoextract. There is tutorial from SMDFlea how to extract TDK bios

          thank you very much! I will try this later today.

          I guess the other bios chip on this motherboard should be ignored? the small capacity one (8mbit, schematic designation: UT4)

                  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,...

                  Problem:

                  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....
