First one is great.  Purchased another about a year later because I work from home.  Second one makes a lot of noise even when I haven't used it.  It suddenly makes a jarring type sound.  Wi-Fi will not stay connected.  Wish I hadn't bought it but I paid for Microsoft Office $160 version and loaded it before I knew this computer would not be quite the same.  Can't return it due to my software expense.  Paid $200 for the first one and $100 for the second computer.
