                              When I put the electric cable the green light only comes on
                              Then it turns off and the fan doesn't turn on or anything.

                                  Do it again more carefully, here is the original file from Lenovo.

                                          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....

                                          BIOS Request - Lenovo Yoga L13 Gen3 (AMD)
                                          by maeson
                                          Hi dear Badcaps-Community,

                                          Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
                                          I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

                                          The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:

                                          Lenovo Yoga L13 Gen 3 AMD:
                                          Lenovo Modell: Type 21BB

                                          Hello everyone,
                                          I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
                                          I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

                                          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

                                          Dear all, I found this forum and this is my last hope. I had a problem with BIOS update though Windows Update - it was stuck for an hour and I decided to restart. Then it bricked. The reason to update was, I had no video on my panorama display. I tried to find a BIOS on my own, but it seems that Lenovo doesn't provide a complete file, only the BIOS section. Is there any chance someone could repair it? I did a backup from the chip, attached. I also tried using another BIOS, slightly different revision. It worked and even I had a display working, but then Windows tried to update once again and it...
