    Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

    Hello everyone,

    I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

    This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

    I have opened the laptop and identified the main BIOS chip...

    Lenovo ThinkStation P520 BIOS file needed
    by Forest79
    Hello,

    I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
    The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

    However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

    Unable to extract bios file from Lenovo bios exectuable
    by survivalbloke
    I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the command
    Code:
    "innoextract 7wcn38ww.exe"
    it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

    The trouble I'm having is that I'm not getting the newly...

    I need a bios file for a Lenovo Thinkpad P1 Gen 3 laptop, model 20TJS2LA1B
    by userbtcku
    I need a bios file for a Lenovo Thinkpad P1 Gen 3 laptop, model 20TJS2LA1B.

    Can anyone help me find the BIOS file for this laptop?
    This laptop is having trouble booting from a flash drive or SSD.
    I've updated the BIOS with a file downloaded from lenovo.com, but it still doesn't work.
    So I'm thinking of flashing it another way.
