In this video, I easily upgraded and installed memory, storage, and a smart card reader; but many people have also replaced the screen, keyboard, batteries, etc. Sadly, this is less feasible on modern laptops due to most components being soldered on. The Lenovo T480 is one of the last of its kind. Due to the age, there is no requirement to buy the latest gen SSDs, RAM, etc. It remains a solid Windows 11 supported home/office laptop, if you understand and accept the limitations.
