I've had my unit, a new Second Generation OLED Yoga from Lenovo for less than two months and the screen went completely dark this morning. After spending the entire morning on the phone with Lenovo support and sales I am Livid. A $2200 sale and they could care less. I was told by Syeda in Atlanta that the best they could do was to return it and they would repair it. I said that was unacceptable and she recommended that I call sales. I asked her if this problem with the screen going dark is something that she saw before and she said yes that I had a bad board. I asked her if she sees this often and she said yes. I have had more than ten laptops in my life and never had this as a problem and she sees this often?  Then I called sales. Ken in sales said that I could return it because it is in the 60 day period and asked to put me on hold to start the process. Then he came back after 15 minutes and said that they could not do that. That his supervisor said it was over the 60 days because it was ordered in September. Even though I did not receive it until Oct 4 and now it’s Nov 30th and it is less than 60 days of use. I then asked to talk to the supervisor and was told no that nothing would change. At is point I was beside myself. I called American Express and finally somebody listened. I will never buy Lenovo again.
