Here is a good way to describe HP. If you needed to run an extension cord down a hallway, almost every manufacturer would just run the cable straight down the hallway. Job done. HP would run 5 different extension cords, run them into every room possible doubling back on themselves a few times just to go down a hallway.
The logic used in their designs completely baffles me. Working on their stuff is like having to take the engine out of your car to change a wiper blade.
The nicest thing I can say about it is that it functioned most of the time. It was big, heavy, slow, ran SUPER hot (like 90C), and felt flimsy to that point where holding it felt like a risk.
At my dad's company there are laptop users who have it docked to their desk 99% of the time with a keyboard/mouse attached and monitor. Some loose connection of the Ethernet cable can cause error 678.

Because of the faulty designs we may get various error messages like destination host unreachable, net unreachable etc.
https://www.corenetworkz.com/2009/05/destination-host-unreachable-reason-and.html Granted, a lot of those were due more to the AMD Griffin chip in there than HP specifically, but it never felt like a "well-built" machine, even when compared to the cheap Dells, Asuses, and Toshibas that my colleagues had.
