ThinkPad quality laptop, and that says almost enough. The T590 is a very powerful workhorse laptop, 15" variety, with the number pad so many of us can't live without. These newer laptops all use USB-C type chargers and Thunderbolt 3 docks (USB-C plug, but with extra features going through it). You can still get a standard looking dock, that you sit the laptop down onto, but it does not connect through the bottom like they all did until a couple of years ago. Be careful that you get the correct dock. There is an Excel spreadsheet available on Lenovo.com that is called the Accessories Compatibility Matrix, or something along those lines. Very helpful for figuring out which docks and port replicators will work.
