One month old. Wifi quit working. Windows disabled it due to a problem. Call the worse customer service department I have ever experienced. After running around in circles pushing button after button to get to someone the guy says in a very muffled very difficult to understand voice hold button on side for 30 seconds. during that time the call dropped. It started all over again. Dropped another call with someone that sounded like they were watching TV or something while talking to me. I ended up calling someone else to resolve the issue. He tells me it will continue to give problems. I am disgusted with the customer service and will regret from this day forward ever buying this product. My advice to any one is do not buy Lenovo...period. get another one that is made of better quality and better service!!!!!
