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.

Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

Lenovo Yoga L13 Gen 3 AMD:

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... -
