desktops are easier to upgrade and replace parts on. In many cases you can service them yourself. They also are less likely to over heat.
Portability ! A laptop computer can be taken anywhere - since it has a buit-in battery - it doesn't always need to be plugged into the mains.
if you mean why is a desktop preferred over a laptop. then i would answer that they aren't and that laptops are preferred because of their convenience
It could harm your computer but its not likely i suggest going to a store and buying a computer fan that goes under the laptop or if its a desktop computer it will be fine. If it does break down from the over heating then its not a good computer company. One of there many focuses for a computer is to control the heat thats coming from the computer.
advantages of hp laptop
some people find laptop computers a bit awkward to use, using the mouse pad takes getting used to, the keys/monitor may not be in the right position you are used to, and I think upgrading a laptop may be difficult if impossible, you can buy add ons like a mouse and extra hard drives but then the laptop becomes harder to carry around. Modern laptops are quite powerful but i would say cost more than the desktop equivalents. Ask a friend if you can borrow one for a few days just to see what there like before you buy.
