The Lenovo U430toch is my opinion super Ultrabook. The Nvidia graphics card, it can also play games with no real loss. He is quick, handy and super quiet. All in all excellent value for money. What one or two troublemakers could, there are no maintenance openings For example, to rid the Ultrabook of dust, however, provides the Ultrabook a way the dust by means of a preloaded program that accesses the fan to remove.
