Talking about this lenova E49 laptop will let u know how does this will help humans.This laptop Is not user friendly , difficult to operate and high maintainence cost.Thia laptop has the basic version and does not have that satisfying features.The battery is drained fast and the lappy has a huge weight and cant be carried out easily. The design is also not at all good as it has a sharp edges which can troble the person using it one or the anither way.lets talk about its cost it above 15k and not worth investing that much for buying it . After few months this laptop starts working slow and hangs frequently. Idefinitely doubt about its service it may be having a very less years of service.thankyou
