I am using this laptop for an year .i and my friend buy new laptops at a time he buy other company.both the laptops have same cost.but now my laptop is working in the same way as like one year back.but my friends laptop is become slow .that is the main advantage of lenovo laptops there functionality and speed is very good.but the main drawback of this laptop is it become heated up very quickly when we play games.now its cost is also very less it will be more useful to middle class family students.at last the support and service of this company is very goog.
