Re: ThinkPad L450 _ NM-A351 BIOS Password Unlock
It looks like your BIOS file is corrupt, try reading it again.
It's just a BIOS chip like in the picture.
8MB Chip?

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 successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

Dear Badcaps,
Is there any available method to perform a bios password unlock on an ThinkPad L14 Gen 4?
CPU is Ryzen 3 PRO 7330U.
What about though Lenovo? It has the best support plan. They asked for the receipt, however it was sold though a reseller.
As a sidenote I was always able to unlock any dell laptop with the master code by simply asking dell and providing a reseller/refurbisher receipt.
Thank you very much! -
