A laptop will only have a numberpad if it is a "full size" 15.6" laptop. There are 15.6" laptops out there which are close to the size of a 14" laptop because they have very thin bezels around the screen, but they do not have a numberpad. The Dell XPS 15 is an example.
If you want a 12" - 14" laptop and have a numberpad, then you need to buy a separate numberpad that connects to a USB port.
