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

Hello everyone,
I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)

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- Barebone / Chassis: TongFang GK7MRFR
