YOU TAKE AIM AT THE BOUNDARIES, WE'LL HELP YOU BREAK THROUGH.
Whether you're an overachiever or an up-and-comer, ThinkPad laptops are the tools you need. From the thin-and-light wonder to the heavy-duty mobile workstation, they're built, tested and enhanced for reliability, durability and speed.
Baked, battered, blistered.
ThinkPad notebooks endure a lot before they ever reach 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.
