Four Awesome Modes. One Incredible Device.
Easily change between four modes — Laptop, Stand, Tablet, and Tent — while your system automatically switches system settings and locks the keyboard in place. The secret: ThinkPad Yoga's unique design and touchscreen display allows the screen to flip around 360 degrees, which means you can select the mode you use based on what you choose to do.

Ultraportable for Easy Mobility
Starting at a mere 1.58kg (3.5 lbs) and just 19mm (0.75") thick, Thinkpad Yoga is ultraportable — it's perfect for doers on the go.

Industry-Leading Multimode Keyboard
Pioneering ultrabooks need pioneering keyboards — and the ThinkPad Yoga's innovative lift-and-lock keyboard fits the bill. When your Yoga switches between modes, the keyboard frame automatically rises and the keys lock, eliminating accidental keystrokes and providing a more comfortable grip.

Massive Storage Options
With up to 1TB in HDD storage/256GB SSD storage, the ThinkPad Yoga has plenty of space for all of your important files, videos, photos, and presentations. And the Lenovo Performance Booster enhances performance by up to five times.

Rock-Solid Durability
The ThinkPad Yoga's durable magnesium-alloy frame and heavy-duty, scratch- and smudge-resistant Corning® Gorilla® Glass display means it can handle tough treatment from even the hardiest road warrior.

Digitizer Pen Support
Choose a model with an optional digitizer pen to maximize productivity on your ThinkPad Yoga. In all four modes, the digitizer pen provides a natural, fluid, writing experience and lets you take notes, sign documents, annotate PDFs, and more.

Long Battery Life
The ThinkPad Yoga lets you stay productive over the long haul. With up to 8 hours of battery life — and a 30-day standby — you can go all day without recharging.

10-Point Multitouch Display
Interact with your ThinkPad Yoga by using simple, intuitive gestures directly on the 12.5" HD or FHD 10-point multitouch display — optimized for Windows 8. Its advanced multitouch technology provides a superior touch experience, greater responsiveness, and faster response times.

Instant Resume
Stay productive by picking up where you left off in an instant. The ThinkPad Yoga wakes from sleep mode in less than 2 seconds and from hibernation in less than 7 seconds.

Robust Hard-Drive Protection
Enjoy peace of mind knowing that your data is protected. The ThinkPad Yoga's Active Protection System locks and protects your HDD when it detects sudden movements — it's like having an airbag for your hard drive.
