        If there is a sticker on the back of the machine with the serial/machine type post a picture of it

          Unfortunately, the label has been removed, all the information is in the bios, only the serial in the bios is written, the machine model appears, there is an explanation in the link

                            Lenovo ThinkStation P520 BIOS file needed
                            by Forest79
                            Hello,

                            I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
                            The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

                            However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

                            by survivalbloke
                            I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the command
                            Code:
                            "innoextract 7wcn38ww.exe"
                            it should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.

                            The trouble I'm having is that I'm not getting the newly...

                            Hello Everyone,

                            I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:

                            https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI

                            In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it...

                            by claws77
                            my laptop is lenovo flex 5 14ITL05

                            recently my power supply for this laptop developed a fault.
                            which caused a short in my usb c port -- verified with a new charger.

                            rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
                            I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32...

                            Unable to extract Lenovo BIOS file from installer
                            by survivalbloke
                            I'm working on a Lenovo LOQ 15APH8, Serial# MP2L9MAV. I want to flash a new BIOS onto it, but I'm also trying to learn this process for my own enrichment and professional development.

                            I was watching some tutorials, copying the serial info blocks from the old bios to a new bios. Before that though, they use innoextract on the Lenovo .exe. I downloaded Innoextract v1.9 but it tells me my .exe is not a supported inno setup installer(see screenshot). So if I unpack this using 7zip, I do get a .ROM file, but according to my tutorials, I'm looking for a .FD file.

                            How can...
