Just wanted to warn potential buyers did after just a few months the screws kept falling out of the bottom of the hinge setting, and then the casing on the left hinge broke. I had a small child Assumed had let the laptop slide to the floor ... my husband inadvertently managed to open the casing and realign the hinge and reclose. The casing around the hinge Very Quickly broke open again - guarantee now expired - and then I discovered on the Lenovo Customer Forum thatthis is a very frequent occurrence. It Appears to be a design fault - internal plastic construction simply can not support the weight of opening and closing laptop. Otherwise I love this laptop, keyboard feels lovely, never had any problems - but it's totally unusable. Have to carry it around the house open, Carefully, in two hands, and shut the casing on the left back is threatening to fall apart further. Plastic covering over the fan next to the hinge so shattering under the strain. Hands off. Will never buy Lenovo again.
