I have a Yoga 2 Pro model #20266. The display will begin flashing when on battery, usually after the power level gets to around 50%, but sometimes before. The flashing stops when plugged into AC. I keep my machine updated regularly and there are no driver updates indicated when doing a system scan using the Lenovo update tool. I've also done a complete system check, including a battery health check.
