Hello everyone,
I need help clearing the supervisor BIOS password for my Lenovo ThinkPad.
Here are the exact device details:

• Laptop Model: Lenovo ThinkPad X13 Yoga Gen 3 (Type 21AX)
• CPU: Intel Core i5 vPro (12th Gen)
• Laptop Serial Number (S/N): [PW03JBL2]
• BIOS Chip: Winbond W25Q512JV (64MB)

I have attached the original 100% verified double-dump bin file (.zip format). I tested it with fc /b and it's a clean read.
Thank you in advance for your time and support!

"Thank you for the reply. Currently, I only have a modified CH341A and a Raspberry Pi 3, so I cannot read the EC/IO chip directly. Is there any known alternate method for this Type 21AX board using a patched 64MB main BIOS to trigger an EC wipe, or is a specialized EC programmer (like Vertyanov or RT809H) strictly mandatory for this model?"
