Re: Need bios & ec from BDL50 LA-D704P REV:4.0 for HP
Still wrong, I think so problem hardware. After push power buton UC1 not read UC2 (25B64), 3,3V ok, no clk pin7, oscillations YC2 UC1 ok. Or wrong EC 128kb in KB9022 inside memory, is possible ?
I hope that I will be understood.Comment

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)
- Secondary

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

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
