HP is very successful company in laptops brand. In this series there are some several mistake like some time in screen show a vertical white line and it cannot remove easily. I ask to shop and they said this problem has no solution and it automatically remove after some time. But if we talk about processing it is very good compare to any other brand. And there services are also good. Pavilion serious is very good. Because its look is very stylish and every new time it discover new look and new program. But finally it inprove some more things.
