I have sent my laptop for repair, still in warranty, they have sent it back with exactly the same problem, when I complained about to their useless customer service they replied that it is been repaired and if I am not happy to resend the laptop back , which I have done and again they said it is fixed but this time the laptop didn't arrive yet because they're so poorly qualified that they can't sent a parcel. I can't express my disappointment and regret that I have purchased a asus product .Their customer service is the worst I have ever encountered.
