                                          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

                                          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....

                                          So far I've been a silent reader, but now I need your help

                                          I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
                                          I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
                                          The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

                                          Lenovo Thinkpad X1 carbon 11th Gen BIOS problem

                                          Hi everyone.

                                          I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...
