13.3" ThinkPad X1 Carbon starts at just 1.28 kg (2.83 lbs), yet it's durable with carbon-fiber construction and packed with premium features like an Adaptive Keyboard that changes automatically with apps, RapidCharge battery technology, a patented cooling system, and a stunning ThinkPad Precision Display.The unique Adaptive Keyboard automatically changes the row of function keys depending on what application you're in. Less clutter, more function, and a streamlined keyboard that anticipates your needs.
Constructed with satellite-grade carbon fiber, X1 Carbon is the toughest ThinkPad ever made. In fact, we perform eight separate military specification tests—all under extreme conditions with dust, vibration, heat, cold, altitude, water, and humidity—so you can laugh in the face of spills, drops, heat exposure, or anything else life throws your way.
Even with its ultrathin design, the new X1 Carbon stays cooler than ever. In fact, we re-engineered our patented fan blades—so X1 Carbon provides the same cool and quiet performance you expect from a ThinkPad.
