Summary: I bought this as a new item and when i got it it came a blank screen, and the seller didn't want to answer about this malfunction, the repair cost 250 dollars and now is finally working. Also i don't like the covers of the usb ports, they are so annoying; it can't be opened on a flat surface, you got to lift the laptop a little bit to oper the covers.
Summary: Suddenly the battery stopped holding a charge. That had happened to me with other laptops and I knew that possibly removing it and putting it back again would fix the problem. Well it did too in this case, but I had to remove cover, keyboard and some other components before I could reach the battery and actually disconnect / reconnect it, always afraid of breaking something. Awful design for end user. Also the access to usb, hdmi, card reader, ethernet is a real pain.
Summary: The openings at the side are dreadful. Once opened it, s almost impossible to, put them back in place. I expected something lighter cause it weighs like hell. The samsung operating system is sooooo much better than this one.
