              Yes, it's ready to flash, S/N inserted, latest BIOS version
              Erase - Program - Verify on AsProgrammer/NeoProgrammer software, make sure you get a good connection if using the clip

                  Attached is a macro script that can copy the DMI (serial number etc) from your backup to the new bios, read the README.txt file how to use it.
                  Thank you very much, the laptop started up. Does this macro only work for the Lenovo Legion Y540-15IRH BIOS ?

                    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....

                    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...

                    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...
