    Thinkpad X1 Carbon 5th Generation DX120 NM-B141

    Hello!
    I'm looking for help with Thinkpad X1 Carbon 5th Generation DX120 NM-B141:
    - no image
    - fans spins for second or two (not sure why once it is second and once its two or smth)
    - keyboard and power button lights for split second

    Not sure about SN because sticker got worn after time.
    Any help would be appreciated!

          Hello everyone,
          I have a ThinkPad X1 Carbon 5th Generation with the motherboard DX120 NS-B142 and the BIOS Chip WINBOND 25Q80JVNIO.
          Serial Number: PF-0RLY18
          I tried to read the BIOS, but it seems to be corrupted.
          The Laptop doesn't boot properly:
          - after pressing reset button:
          - 4x POST Beep
          - rebooting
          - 2x POST Beep
          - no visual output to any screen (laptop screen or external monitor)
          - fans spins but after a few seconds shuts down again
          - keyboard and power button lights for split second

          Any help would be appreciated

              NS-B142​ is the part number for the Power Button Switch Board & Cable. The file you posted is from the wrong chip, it isn`t the bios it is the thunderbolt firmware.

              post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

              Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

              >>>>> https://www.badcaps.net/index.php?pageid=donate1 <<<<<

              Every donation made will go towards server fees and maintenance costs.

                  Thank you for your help! I thought I was talking a different device because of the NS-B142 / NS-B142, but I know.
                  I think I found the right chip then: WINBOND 25Q128FV and I extracted this firmware. Can anyone confirm that this image is broken or smth? The BIOS is password locked if this is important.
