I ordered and fitted one of these replacements for the charging socket on my T520.
That means over the years I have had it I’ve upgraded: the charging socket, the RAM, the display panel, the CPU, and swapped the HD for an SSD!
Swapping the charging socket over does require pulling the laptop apart a fair bit, but quite manageable as long as you take it step-by-step and have a good system to keep track of the screws.
