Unlike the popular belief, I've had a very bad experience with the services of Flipkart with this order of Lenovo laptop. The specifications mentioned on the website are different from what I received. The option for return and replacement didn't help either. Instead of sending the model posted on the site, I again received the same product with AMD graphic processor and DOS operating system which I did the first time!
Battery backup is onlu 2-2.5 hr...size of the battery is too small...looks like some AA size batteries are aligned one after another.
