Re: thinkpad 13 Gen1 locked bios
you can just make your own clean img from lenovo btw just overwrite firmware bios region (offset 0xa00000 for this model) with the image from lenovo driver firmware update page extract it with uefitool for linux cab or the windows one self extracts the bin file for you. just make sure to keep the original gbe region; ME region etc. same idea for other manufacturers but youll have to splice the nvram region contained serial number etc since the product data is contained in efi. no need to download other people's dumpsComment

hello friends - I have purchased a used Thinkpad X13 Gen 3 AMD variant and only after making the purchase I realised that the BIOS is locked. I have spent a bit of time browsing the forum and from what I understand it's possible the modify the BIOS that is currently on the machine and remove the password from that BIOS. For dumping the BIOS from the laptop I have ordered this ch341a programmer. Below is a photo of the password prompt:
I have taken the cover off the laptop and I found that "serial number" is "GM-0358MB" and "type number" is "21CN-S19U00".... -
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... -

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
