Performance on the go
Powered by 10th Gen Intel® Core™ processors, the Yoga C640 gives you an unbelievably responsive computer experience. Featuring built-in intelligent performance features that anticipate your needs, the device offers a more intuitive and personalized experience.
Opt for constant connectivity
With optional LTE connectivity in select markets, you can access the internet wherever the day takes you—even without a WiFi signal. Or opt for Intel WiFi 6, with 75% lower latency than standard AC WiFi. Stream smoother and browse with no delays—you’ll connect with unprecedented speed.
Measuring 16.9mm and 1.25kg, the Yoga C640 offers ultraportable style with a sandblasted aluminum cover. Rotate from laptop into tablet mode and back, with a 360-degree convertible hinge designed for stability no matter your mode.
Forget your charger
The Yoga C640 offers up to 22 hours of power*. Take it anywhere, leave the charger behind, and stay focused on what matters.
*Based on testing with MobileMark 2014. Battery life varies significantly with settings, usage, and other factors.
Vibrant visuals & sound
Featuring the vibrant color and clarity of a 13.3-inch FHD wide-angle display edged with narrow bezels on all four sides, the Yoga C640 offers a brilliant entertainment experience. With up to 400 nits of brightness, you’ll see every detail—combined with the rich, layered sound of front-facing speakers and Dolby Atmos™ when listening through headphones.
Log in with a touch
You can forget your password, thanks to the Yoga C640’s integrated fingerprint reader. Touch it and log in—it takes less than two seconds.
Maintain your privacy
Lenovo is committed to protecting your privacy. Slide the Yoga C640’s TrueBlock Privacy Shutter closed for true peace of mind when you’re not using your webcam.
