          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.

          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 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 IdeaPad 3 - Hard Disk not recognized in BIOS
          by mkdj
          Dear all,

          I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

          Here the steps I have taken to fix the laptop:
          - downloaded latest BIOS from Lenovo Website...

          Lenovo IdeaPad 330 15-AST 81D6 BIOS Recovery
          by jendkkd jeje
          So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

          I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
