This is the second Lenovo Laptop I have purchased.  The keyboard on the first one stopped working and you could not find a replacement for it at the time.  This one has stopped powering on within 90 days of purchase.Lenovo did repair the unit without hassle.  They replaced the motherboard.  But I still give it 1 star due to the fact that of 2 Lenovos I have bought, both stopped working within a short time.
