    Lenovo Legion Y540-15IRH - need BIOS or help with DMI

    Laptop - Lenovo Legion Y540-15IRH 81SX
    MB - NM-C221 Rev: 2.0
    CPU - SRG1T (i7-9750HF)
    PCH - SR40B

    I don't have original bios dump from this laptop. Somebody tried to repair it and left it with non-working bios.
    I repaired this MB and tried bios dumps from this forum, and some of them work, but there's no DMI data in bios (Product name, MTM, Lenovo SN)

    I ask for some dumps to try out or help with adding DMI manualy (I do have a sticker with DMI info)

          Thank you for reply.

          I tried that tool on this laptop before.
          I followed the instructions but i get "Init. SMBIOS ERROR" whenever i try to write or read something with amidedos on this motherboard. amidedos works fine, because it returns commands that i can use with it.

          Have you sucesfully used this tool on this motherboard? If so, I might be doing something wrong

                  Lenovo Legion Y540 – Need help repairing BIOS after bad downgrade
                  by gestalt.exe
                  Hi everyone,

                  My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
                  Laptop stopped booting entirely.

                  I used a CH341A programmer to dump the corrupted 16MB BIOS.
                  i then attempted the following:
                  1. Downloaded stock BIOS BHCN39WW from Lenovo
                  2. Trimmed it to 16MB
                  3. Extracted the BIOS region from the corrupted dump
                  4. Extracted the BIOS region from the stock 39WW
                  5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
                  6. Injected back my LDGB / DMI
                  ...

                  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...

                  Lenovo Legion Slim 5 16APH8 (RTX 4070) - Turns on for a few seconds then shuts off. BIOS issue.
                  by riko 656
                  Hello everyone,
                  I need help with my Lenovo Legion laptop. It turns on for a few seconds and then immediately shuts down. I believe this is a BIOS corruption issue.
                  Laptop Model:
                  • Model: Lenovo Legion Slim 5 16APH8
                  • GPU: NVIDIA GeForce RTX 4070
                  • Main BIOS chip size: 32MB
                  • VBIOS chip size: 16MB
                  Problem Description: The laptop was working perfectly. Now, when I press the power button, the keyboard lights up and the laptop powers on for just a few seconds, then it shuts itself off completely. After researching, I am convinced it's a corrupt BIOS.
                  What I Have Tried So Far:
                  1. I

                  Summary of BIOS Whitelist Removal Problem


                  Problem:
                  I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                  Initial Findings:
                  • My current BIOS version is N1KET58W (1.45).
                  • I have a CH341A programmer and have successfully created two full backups of my BIOS.
                  • I have the ability to use command-line tools on a Linux machine.
                  Troubleshooting Steps & Conclusions:
                  • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                  • I concluded that the

                  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....
