©Constructed™ with satellite-grade carbon fiber, the new X1 Carbon is the toughest ThinkPad ever made. In fact, we perform nearly a dozen separate military-grade specification tests—all under extreme conditions with dust, vibration, heat, cold, altitude, humidity, solar radiation, and fungus. You can rely on ThinkPad despite what life throws your way.And of course, the full-sized, backlit keyboard is spill-resistant, as you’d expect from a ThinkPad X1 Carbon.The military specification tests are not intended to be a guarantee of performance under these environmental conditions.
But Stay Unplugged
With the X1 Carbon, you can stay connected, yet go unplugged more than all day, as the battery lasts up to 11 hours*.* Based on testing three different product configurations with MobileMark 2014. Battery life varies significantly with settings, usage, and other factors.
