Whilst I would tend to disagree with what BK 123 has said about soldered in CPUs I would have thought the best people to ask would be Hewlett Packard. I also do not think it would be financially viable to upgrade a CPU in a laptop I do not think you are going to gain much, if anything, in performance. Laptops, generally, are built to write letters on and not much else. Buy a gaming machine with "future proof" (yeah right) hardware built in. I am not suggesting you are a gamer or otherwise. what I am saying is that if you want
a fast machine, which is obviously your aim. buy a fast machine rather than a CPU which will not make your letter writing any faster.
