It was my second laptop in my life. hp elite book 840 is the best laptop in this price range. built quality of this laptop is damn good. I have not words to explain its body material. keyboard switches are unique and easy to use. most of the times laptop’s keyboard switches are joint with each other and it makes some problem to type fast. but in hp elite book there is no such issue. its ram gives the fast speed. I have not seen any bug in its Window 10. screen quality is outstanding. moreover it is a big brand and hp gives best service to customers also. nutshell it is a good laptop for professionals.
