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...

So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.

Hi

- takes long time to restart.
- sometimes powers on and then off

As ME analyzer gave me an error i just decided to write bios with a cleaned bios from E7270 bios post.
I reinstall...

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:

• 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
