Try the auto-patcher https://www.badcaps.net/forum/showthread.php?t=87588
And don`t post your bios again in another seperate thread when you`ve already posted it here.Comment

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -

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... -
Serial Number: PF42HXCM

P16s Gen 1 (Type 21BT, 21BU) Laptop (ThinkPad) - Type 21BT
Hello, I have a Lenovo ThinkPad P16s Gen1 with a likely corrupted BIOS.
As soon as the power adapter is plugged in, the fan runs at full speed, but nothing else happens. When I search for the original BIOS version with UVPD, I get N3BET61W, but this exact version has been withdrawn by Lenovo.
Unfortunately, I can't find any other original BIOS for this model.
I've already tried creating a new BIOS from version 1.40,...
