                      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 TD350 ThinkServer BIOS v505 Corrupted BIOS,
                      by TylerHyde21
                      Hello, the bios on my Lenovo TD350 ThinkServer got corrupted during a bios update, the bios restore function killed the Server.
                      I need to flash the bios inside the MX25L12835F SOP8, i have already desolder the chip and solder it into my SOP8 adapter and read it with a ROM programmer.
                      I use the innoextract 1.9 software to extract the bios file from the .exe file that i download from lenovo website, can you help me edit the Hex file (removing the Index part and resize the file)?

                      This guy claim to have done it https://forums.lenovo.com/t5/ThinkSe...doesnt-Start-u...

                      Lenovo Thinkcentre M75n DMI Data extraction from dumped BIOS
                      by Kentsfield
                      Hi,

                      I got a Lenovo Thinkcentre M75n (MT-M 11G5 PF3XG5V3) with a semi-bricked bios.

                      Short recap: I want to add an external GPU via the M.2 slot (Oculink). It does work but has some problems with the onboard GPU of the Ryzen 3 3300U. So I used Smokeless_UMAF to disable it. Since then I don't get any video via the external GPU nor the iGPU and Can't access the BIOS, but the PC does boot to the OS.

                      I desoldered the flash IC MX25U12872F and dumped the flash.

                      I also downloaded the newest BIOS and have it as a .bin file (I loosely compared the contents...

                      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

                      Help Lenovo Workstation P910 BIOS Request
                      by personanongrata
                      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...
