We offer hundreds of replacement keyboards for HP laptops, and they come in three types: non-backlit, backlit, and keyboard with top cover. If your keyboard stops working or the keycaps are damaged and come off, it is necessary to replace it with a new keyboard. In order to make the notebook light and thin, most of the current notebooks use a built-in keyboard. It is very troublesome to replace the built-in keyboard. If you are not a professionally skilled person, then I suggest you choose a keyboard with top cover, because it is easier to replace the keyboard with top cover than to replace a single keyboard.
