Lenovo G50-80 is very good laptop as its configuration is best compared to its cost.It’s very good and very easy to use and user friendly. The keypad keys and mouse are also very comfortable for long time usage. Service center are also more in every state so that there is no issue in resolving it and every service center will be helpful, once I have raised a complaint about my system in one of the service center they responded very nice and very helpful.
