    BMAX B5A Pro G7R2 Bios

    Hi all,

    i got this Mini PC with a board damage and repaired it. When i plug in the power supply the unit starts directly but the fan is only giving a short twitch. Nothing else happens and i turn the PC off with the power button.

      🛠️ 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

      [Problem/ Request] Bricked TongFang GK7MRFR BIOS
      by cr4zychriss
      Hello everyone,
      I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
      I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details

      ASUS Zenbook Pro Duo UX8402ZA BIOS
      by pirati
      Hello everyone,

      I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

      When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

      I decided to try flashing a new BIOS, but since I didn’t want to desolder...

      by Deniz
      Bu: https://pcsupport.lenovo.com/tr/tr/p...065tx/mp2br7d9

      Hello everyone,

      I have a Lenovo IdeaPad Gaming 3 16IAH7. When the device first arrived, there was no display at all.
      I had the BIOS cleaned, but the issue was not resolved and there was still no image.

      Later, I flashed a different BIOS dump from the same model. With this BIOS, the device boots and display works, but the GPU is not detected in the BIOS (RTX 3060 is missing).

      After that, I tried to update the...
