Thinkpad 11e unlocking bios

Just wanted to specify whether it is possible to unlock the bios by shorting 5-6 pins for EEPROM. The method works for majority of thinkpads.

The motherboard is LI6 DA0LI6MBAD0 REV: D
(Processor is Intel Core M-5Y10c)

Lenovo Thinkpad X1 carbon 11th Gen BIOS problem

by MaxonDomkrat

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...

🛠️ 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

Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted

by Loki_Fido

Hi everyone, hope everyone's having a great day.

Does this mean the BIOS is fine? making it a hardware issue?
