    Lenovo X1 Carbon 7th Gen Type 20R1 BIOS DUMP

    Lenovo X1 Carbon 7th Gen Type 20R1
    SN: PF1Y5BBJ
    Board: GX490 NM-C661 Rev: 1.0

    I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

    The problem with the laptop is that it will not power on. USB-C meter shows 20v is negotiated, but does not show charging current if battery is connected, and nothing happens when power button is pressed. Any help is greatly appreciated.


    Here is my dump.

      Only the win key is in the bios,the DMI is in the EC. Seems to me like you`ve got a hardware problem rather than the bios

              Need BIOS Dump/ROM for Lenovo Thinkstation p500
              by AHmad_Salal
              Hello all,
              I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful....

              Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
              by Ahari
              Hi all,

              This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

              I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

              I...

              [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
              by hyperwood
              Hi everyone,

              Iā€™m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

              The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

              I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā€“ and the last 2MB in those files are just FF FF FF....

              āœ… What I need:
              • A working 2MB BIOS dump
              • Matching NM-E471 Rev. 2.0, e.g. JY575
              ...

              I need a BIOS dump for the Samsung S49CG934SU monitor
              by Habble7
              The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

              Suspected Cause:
              I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

              Troubleshooting Attempts:
              ...

              BIOS N3YET06C (0.06)
              Hello! I need help getting a modified BIOS for my system. Since I have an engineering processor, is it possible to add the microcode of this engineering processor to the latest BIOS for this laptop model? I think since the BIOS is old, that's why the Wi-Fi driver is not installed on Win10 and Win11, the sound is not adjusted (error code 10 in the device manager) and the screen brightness. The laptop also has BIOS chips W25Q512NW and W25Q128JV, how can...
