Amazon is not serious about sellers what they are sending to customers. Intentionally faulty laptop was delivered to me. It was not charging when it was delivered. After half an hour battery was empty. Refund policy of Amazon is pathetic. To get your money back after mistake of Amazon itself is not easy. It takes long time as well. Please do not buy refurbished laptops from Amazon.Amazon intentionally has selling not working laptops to its customer. After that you can not replace or return it. They will fail the return in performance check. Beware of Amazon.
