Excellent notebook that is well worth much more expensive products. The screen is a good size and very good quality. The buttons fall well under the hand and typing is done naturally and easily as on a desktop keyboard. 2 Functions are very significant: being able, at the touch of a button, disconnect the touch pad and the function that allows air to be able to watch a film without interfering with the switchgear panel. Test result, the battery autonomy 7am, in power saving mode and connected with optical mouse. The fan does not intend virtually. The speakers deliver sound of the highest quality. In summary, a laptop for those who do not wish to invest an astronomical sum in this type of device, and makes perfect (and more) that q'on asked.
But here !!!!! after 4 days more sound. Super fast and Exchange amazon rebelotte ... 4 days after more sound. After checking on the net, it seems that this is a recurring problem on Lenovo (several models affected) As I think about a new device I do not have to hack to make it work, I ask for refund.
