I bought this laptop 2 months ago. The keyboard of the laptop is not working properly. Battery backup is very bad, battery is drain after 1 hour of use. Without windows 10 its nothing. No drivers CD not even a useful user manual is provided inside the box. When I paly high graphics game the laptop gets totally hot. I am really dissatisfied with Lenovo Service, the technical team as well as the on-site technician wasted my time without performing any actual task.
