Hi everyone.
I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto... -

I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele... -
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

Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.
I have a few questions:- If I would buy this laptop and have
