    Lenovo thinkbook 14-iil BIOS

    Hi team,

    I bought a lenovo thinkbook 14-iil with a core i 5 processor, Radeon graphics chip, board number: DALVACMB8DO - REV D from an auction. It does not have a bios chip and my guess is that someone disoldered it, so I am planning to buy a new replacement bios chip but I do not know how to reprogram the chip, can someone assist please

      I have read the information in the link share, thank you. My only question is, am I able to reprogram the new bios without the original image?

            Thank you, the bios has worked though the laptop has no video output and it is constantly rebooting after a minute or so.

                      This is your original bios. Did it work before?

                                        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....

                                        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 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...
