The ThinkPad T14 Gen 1 AMD was released in 2020, and it is actually one of the newest / youngest laptops I ever had. Since I am using Linux Mint, which is based on Ubuntu LTS, the kernel is relatively old and I realized that I need to update to a new kernel if I want to have good hardware compatibility.
The latest release of Linux Mint (20.3) is still based on Ubuntu 20.04 LTS, not Ubuntu 22.04 LTS which was just released -- usually Linux Mint will get a new release a few months after the Ubuntu LTS release. Therefore, I'm upgrading to the latest kernel available in the Ubuntu 20.04 repositories.
