I am one of the first few purchasers. In just two years function keys fails. Chennai Adyar says software issue and load driver. Worst client experience at Adyar. The center person tells we need to diagnose keep the laptop for two days and let us See. Battery fails in another few months.Trying to get replacement. Poor response on availability.
Answer you get is go on trying in once center or other. Utter failure of customer service. If you want to buy buy a brand that has the official service centers. Not the one that gives franchise to any one with a screwdriver and spanner.
