I got this in November 2013, and can now concluded this computer is trash - dont buy it.
1) It comes with a hybrid HDD, which stalls the computer at boot, so you have to force shutdown almost every time.
2) The display is fuzzy, too low brightness, zero viewing angle..
3) Problems with touch, to close a windows often need several attempts.
4) Comes with Windows 8, which is a seperate problem, but never the less, windows close by them self, windows pops up - Windows 8 is not for notebooks, Windows 8 is for tablets with no keyboard or mouse.
5) Build-in security chip prevents to install, or make it almost impossible, to install a new OS. I have ordered Windows 7 Prof discs from Lenovo, only cost is the cost of shipment, good service, but havnt got the time to try install Windows 7 - my wife now got it anyway.
6) WiFi antenna is very weak, connections drops frequently due to the weak antenna. You need an external antenna atached to make sure you have a steady signal.
7) Compared with the competition, its a bit heavy.
But apart from above, back lit keys with two levels, nice design are the only features which can be said positivley about this S440, but does not at all compensate for the numerous of problems, unfortunately.
