Summary: I bought this laptop in September 2012. It's very slow to start up and do things. Now two months later, the screen is broken -not by physical force (it was working fine, closed the lid and came back to work after dinner, half of screen was like covered by ink). Called Sony support centre and was told that the screen never breaks by itself, definiely not covered by warranty.
