Whether you're an overachiever or an up-and-comer, the Lenovo Ultrabook ThinkPad Black 14 X1 Carbon 20A7002QUS Laptop PC with Intel Core i7-4600U Processor is the tool you need. From the thin-and-light wonder to the heavy-duty mobile workstation, it's built, tested and enhanced for reliability, durability and speed. This Lenovo laptop computer with 256GB solid state drive and 8GB memory endures a lot before it ever reaches you. We meticulously design many of them to pass rugged military spec tests. We outfit them with spill-resistant keyboards, roll-cage technology and shock-mounted hard drives. And we test them in ways you can't imagine - baking, battering, blistering and blowing them with sand.
