    Lenovo Y40-80 bios

    Hi all, I have a Lenovo Y40-80 that I am trying to remove the Admin password for. There is a password screen that comes up immediately that I can input a user password for (Pic 3) and this will allow me access to Windows or the BIOS, but a majority of the options are grayed out in the BIOS (Pic 4).

    I have attached a picture of my overall chassis and a close up of the chip that I have read (using CH341A and AsProgrammer). I output two files from the chip and compared them (fc /b) and they were the same. I patched the first file (the file felt like it processed too quickly) and then wrote it onto the chip. I started the computer and nothing had changed, it quickly just showed the password screen again. I decided to compare the original to the patched files and they were the same, so it seems like things didn't get patched correctly.

    Could anyone patch my original file or guide me to where in the process I've gone wrong? Thanks

            Hi, thank you for trying. I could not get it to work unfortunately. Computer would power on, but there was only a black screen even after a long period of time (10 minutes or so) and multiple restarts. I reflashed the original back, so nothing lost, just back where I started.

            I am using the CH341A with a clip and I have noticed that I get consistent scans while it's clipped up, but they are not consistent after it's been unclipped and reclipped. I have taken another scan after my most recent clip and will leave that attached. If anyone could try and patch the scan attached, it would be most appreciated.

            I have tried to patch this scan and the script was again very quick and did not ultimately change anything upon comparison, but I am unsure if there is anything that I am doing wrong or missing even after reading everything that I could.

                  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)...

                  Unable to extract bios file from Lenovo bios exectuable
                  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...

                  Help to get Lenovo BIOS bin file for Thinkpad T560
                  by maanee11
                  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...

                  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...

                  Bricked Lenovo IdeaPad 3 14ADA05 Need BIOS file for FN+R Crisis recovery

                  S/N: PF2BZS7D

                  I was having issues with this particular laptop where the NVME SSD would disappear and would not detect unless I took it out and reconnected it, then it would detect for only for a minute then disappear from BIOS. I figured updating the BIOS was worth a try so I booted into my HBCD USB and downloaded the latest BIOS file for that exact model. I ran the executable and everything went smooth, it beeped and then when it restarted, now it won't post, just black screen with fan spinning.

                  I already have a CH341A programmer...
