One of the defining features of the Yoga range has been how it calls to its namesake by featuring a display that can fully flip over to turn the display into an effective tablet. The Yoga C940's 14-inch display come with either a Full HD or UHD display, with the review sample supplied being the lower-cost Full HD variant. The one caveat here if you crave a little tablet action is that the 16:9 ratio does make for a very tall and wide tablet. It really does feel rather like you're holding a super-large phone when you're using it this way.
The display on the Yoga C940 is touch-enabled, but Lenovo also supplies an integrated stylus. It's tucked away to the side of the rear hinge, which is some very neat and compact engineering, although you may struggle at first to pop it out of its secure enclave.
There's a very deliberate slight "lip" on the Yoga C940 that proclaims its branding but also makes it very easy to open and close compared to many other ultraportables. It helps here that the Yoga C940 adheres to Intel's "Project Athena" guidelines so it's exceptionally fast to wake when you open it. You'd basically need Superman-level reflexes to actually try to interact with the screen before it springs to life when you open it up.
Lenovo's Yoga design incorporates rounded keys on the keyboard. I can't say I love them aesthetically – maybe I'm just a keyboard purist at heart – but they're certainly functional with a decent level of key travel for a laptop. There's also a small biometric fingerprint sensor just below the arrow keys. The front facing 720p camera can be used for videoconferencing use but isn't compatible with Windows Hello for login purposes.
The right hand side of the Yoga C940 houses just the power button, leaving all the port action on the left. That includes a single USB-A type port and two USB-C/Thunderbolt 3 ports, either of which can be used for charging. It would be a nice flexibility move for Lenovo to flip one of those ports over to the right to allow charging and data use from either side, but that's not what you get here.
One important differentiator for the Lenovo Yoga C940 is the way its speaker works. It's mounted into the hinge such that when you flip the C940 open, it's facing you for maximum effectiveness, but it also rotates with the screen when you flip it into tablet mode. That means if you're using it for a little sneaky Netflix bingeing before bedtime, you're not firing the sound into your lap, but directly towards your ears. It's a neat design twist – quite literally – that works well.
