    Lenovo T540p bios dumps required for 48.4LO18.021

    Hi, does anybody have a working pair of main/ec dumps for board 48.4LO18.021?

    I have tried with dumps for 48.4LO16.021 which do not work (Lenovo T540P).

    Many thanks

          ok, thanks - here they are. I still don't know if these bios files are good or if there is another problem with the motherboard. These are however accurate dumps..

                      Hi, thanks very much for uploading. I did try them, but sadly, they didn't work. I think the fault is with the board after all. Appreciate your efforts !

                          If you have a motherboard outside, don't forget to connect an additional board with USB and RJ45.
                          If you do not connect this additional board, your NB will not turn on.

                              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....

                              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...
