It's in the details. We re-engineered the fan to allow the Yoga 900 to stay thin and cool. Specially designed vents in the hinge allow for excellent cooling, dust-resistance, and a clean design that’s quiet. And it's beautiful. The elegant hinge is composed of 813 individual components for fluid transitions between modes. Auto Lock hinge technology allows you to easily open and close the laptop, even with one hand. Pick a pop of color with Clementine Orange, dazzle with Champagne Gold, or stick with sleek Platinum Silver, whatever color you choose, you'll stand out from the crowd.
