Remove_SMM... UEFI.

[Hy Boost]

Are you asking because your laptop has a bios password ?

Hi, sorry for the late response. Work and college.
Yes. I am new to this whole bios patching situation in itself but I am giving it a go nevertheless. I realize that I may posted on the wrong topic. My mistakes.

Hello, I need help. I can't unlock my T480.
Type: 20L6-SDR213
Serial No: PF-14H8HB
The BIOS is locked. I performed two BIOS dumps, and both were verified.
The chip is a W25Q128JVSQ, and I used a CH341A programmer. I then patched it, wrote it to the IC, read it back, and confirmed the file was written correctly.
I proceeded to boot the laptop, but there was no display. The buttons light up, a melody plays through the speakers, and then it shuts down.
I restored the original BIOS, and it locked again, but this time the screen turns on and it prompts for F1.
What could be the issue?

I had the same issue and the same BIOS chip. I believe it depends on BIOS version. However here is how I unlocked mine:

1. Make backup of original BIOS... do not patch this one.
2. Find factory image for T480 and patch! I used this one (https://www.badcaps.net/forum/showthread.php?t=79414)
3. Use patched factory image to remove SVP as per instructions for autopatcher tool
4. Flash original BIOS

Hope it helps
