I bought a S340-15API Laptop (ideapad) - Type 81NC which keypad was faulty from the beginning (several keys not working), but because I bought it in France and was back in Canada where I work, Lenovo Canada wouldn't take it to repair it, even if I was ready to pay whatever international extension of the warranty. I had to go back to France to have it repair, it took them a month, and when it came back other keys were faulty, and the back case was cracked by their employee screwing the screws too hard. I had to go back to Canada, because this is where I work, so they won't take it for repair again. They have an awful after sale service for a company that sells such bad devices, they never apologize for anything, the agents are not helpful and just won't write back when I ask for remote assistance. I used to really like this company, they were building strong laptops, but not anymore, they completely deteriorated.
