      password on the 24RF08, not on the bios
      read 24rf08
      Or
      make a shunt on sda scl during startup
      risky operation be careful!!!!
      read the different topics or watch tutorial on youtube



      you can try that if you are a player, never tested on these models?

      if worked
      clean password with two blank password
      and clear security chip
      save and reboot
      after restore your original bios

        je viens de voir qu'il y a aussi une petite puce PS08A sur la carte mère à côté de la puce Winbond 25Q64CVSIG. Cette petite puce contient elle les mots de passes enregistrés?
        la puce Windbond contient le bios que je récupère avec une pince et un ch341. Mais le mot de passe reste présent malgré le flash.

            🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
            by macabook
            Hello everyone,

            I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
            🧩 Initial Issue
            • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
            • External display (HDMI) shows
            ...

            ASUS TP500LA BIOS request/repair/merge?
            by jbonavita
            Hi, my laptop wont boot at all
            With original bios no POST, only LED lights
            With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
            Some issues
            A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
            B- If updated from 500LN version 203 to 300, the battery stops being recognized

            Things I tried

            1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

            [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
            by zenius
            Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

            Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

            Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
            by Wahaz
            Hello,

            I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
            So I thought it was a Bios problem.
            I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
