    Lenovo Thinkbook 14-IIL

    Hello everyone. I have problem most likely with bios because I found no shorts on motherboard, all voltages seem to be present, laptop keeps restarting, the fan spins for a while a then stops when it starts spining again the keyboard lights up and it happens over and over. I tried bioses from other topics and they didn't work.
    I tried to clean ME myself in my original bios but for some reason after cleaning ME, ME analyzer showed that bios is corrupted, still new to editing bios so I appreciate any help or advices.
    Name and model: Lenovo Thinkbook 14-IIL 20SL
    Serial number: LR0EHZVK

      Try first this bios file , rebuild from your original dump.
      If it's not working then try the second file which has a clean ME region.
      Please provide feedback.

                      Unfortunately none of these bioses worked, thank you for the help though, with the last bios you shared laptop switched on but no restarts at all, just in case I hooked up an hdmi cable but nothing happend, maybe it's time to pull out he board and make deeper investigation.

                              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....

                              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 16P G2 ACH - BIOS Serial number missing
                              by TecnicaNTT
                              Hi all,

                              I got a Lenovo Thinkbook 16P G2 ACH on the bench with a botched BIOS (somehow my client blanked it). I restored the laptop and got it up and running with original BIOS from Lenovo Support website.
                              My problem is now that the machine details are missing in the BIOS (Serial Number, MTM, etc.)
                              I tried to write the details with the Lenovo Uone Tool but had now luck. It is giving me an error: "ERROR: Locate protocol with LenovoEeprom, Status=[e]. EEPROM fail when reading or writing data."
                              I am now asking here for help if anyone knows how to do this in...
