There is a reason Lenovo provides a warranty of one year for the X380 Yoga, and three years for other X and T series laptops. I had the good luck to buy one of these X380s refurbished and have it come in good shape. Six months later I bought another for my spouse and had to return it due to a defective fan. It just howled. The seller sent another. At least it was supposed to be another, or the same one with a working fan. Within half an hour of light use, the fan went into ultra-loud mode again. I got a refund. Now the screen on the first is getting defective pixels. I suspect the Yoga style is high risk to buy refurbished, which is unfortunate as the X380 is a beautiful notebook with a nice bright screen.
