Lenovo is refreshing its line of IdeaPad Flex notebooks with the new Flex 14D and 15D laptops, which sport AMD processors on the inside rather than Intels chips. As part of the Flex line, the 14D and 15Ds displays are capable of bending 180 degrees into what Lenovo calls Stand Mode. This differs from Lenovos Yoga laptops, which can bend back an entire 360 degrees to transform the notebook into a tablet.
