Lenovo customer service is horribleI purchased a Lenovo ThinkCentre desktop in 2014. In the summer of 2017, the hard drive stopped working. I spent five hours on different phone calls with Lenovo and the problem wasn't fixed until an IBM person diagnosed it with a service call in my office. She put in a new hard drive that ended up not working after about six months. I called Lenovo and spoke with a supervisor who told me that after the warranty ran out, they would not cover the new hard drive. I explained that it might be defective and that Lenovo might want to keep me as a customer. He said that after the warranty ran out, "you are no longer a customer," and hung up on me after I said I would quote him in Consumer Reports. Beware of Lenovo, the company if you are considering a Lenovo purchase.
