Re: need bin bios for LMQ-1 MB 12298-2
Hello, my laptop is Lenovo Thinkpad X1 Carbon Gen 2 Touch Screen
When I press the power button, the power light, keyboard and touchbar work, then the machine turns off by itself. I tried to turn it back on, sometimes I can enter the BIOS, but then the computer automatically turns off. I have tried many ways but still not working.
My mainboard is LMQ-1 MB 12298-2 48.4LY05.021 and serial number is Type 20A8-S16500 S/N: R9-01VK10 14/05
Please help me!Comment

always when you make a bios request, post the original bios, even if it is corrupted..Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

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

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... -

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
