    Panasonic CF-D1NW200TZ BIOS Issue

    Greetings All

    I have Panasonic CF-D1NW200TZ, it has MX25l12873F BIOS that is protected with password which I want to remove, I made backup with AFUWINGUIx64 and removed password but could not write it to the BIOS again due to some errors coming, so I used CH341A programmer to read the full BIOS data on board and then I deleted the password, then i wrote back the unlocked BIOS file using CH341A, removed protection, then did full erase , then blank check and write, then verify
    all are ok, but tablet refuse to start now, it is just showing power and WIFI LED, nothing more, no fan spin or anything else

    tried to write back original dump, but still the same
    I used another 3 bios dump but all giving same result

    I used several applications ( CH341A 1.31 - ASprogrammer - Colibri)

    any suggestions ?

    here are original locked and unlocked bios files

    Locked ==> https://mega.nz/file/UtZhwLrT#jRSvEK...eG1A4l8zMaxgXQ

    Unlocked ==> https://mega.nz/file/1sIDXI4A#EzFQQu...X0QJ-6ncKm_GnI

    appreciate if anyone can help or point out what could be the issue
    any one has 100% working dump and advice what is the best software to use with CH341A to flash MX25l12873F

          Problem with PANASONIC CF53 laptop after changing BIOS settings
          by AquaMan Ua
          Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

          Samsung Series 9 - BIOS issue
          by Kjell
          After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).

          Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...

          Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
          by wizard13
          Hello everyone,

          I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

          I have checked the forum and the available documentation but could not find a solution specific to my issue.

          Panasonic CF-20G0247VM BIOS Bad Flash Help
          by James Jackson
          I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.

          Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post...
