Lenovo is one of the leading computers manufacturing company after I.B.M. and Apple Inc. As I am using lenovo laptop since 3 years I had never came across any problem related to its hardware.One day my laptop was felt from my bed but nothing happend to it. It is very strong and durable and yo can use it in your own way. How you want to use its your choice.The greatest quality of this laptop is its sound.As the laptop is equipped with Dolby sound system it produces a high quality sound.My feelings cannot be expressed in words about this product. LOVED IT
