Lenovo Yoga C940 14” 2-in-1 laptop tablet review

Lenovo’s Yoga is a laptop and tablet rolled into one.

Courtesy of its “Yoga 360” hinge, the Lenovo C940's screen folds back (essentially) 360 degrees to become a 14mm tablet. But, there are some compromises, so should you buy it? 

Key Specs of the Lenovo C940 2-in-1 laptop-tablet 

14-inch, glossy3,840 x 2,160, touchscreen IPS HDR400 LCD; 1.3-3.9GHz Intel Core i7-1065G7 processor; 16GB LPDDR4X-3733 RAM; 512GB NVMe hard drive; Intel Iris Plus Graphics60Wh battery; 320 x 216 x 14mm 1.35kg. SKU: A10RB. Full specs here. 

Design and Ergonomics 

Not surprisingly for a Lenovo business device, the ‘Iron Grey and Mica’ styling looks as conservatively corporate as you can get. It nonetheless oozes quality thanks to its robust built quality, sharp lines, and 14mm thinness. The chassis is made from aluminium and the lid is very stiff with very little flex in it. It protects an impressive screen which offers a very bright (500-nit), Ultra HD, 3,840 x 2,160 resolution and which supports 90 per cent of the complex, DCI-P3 colour gamut. Colours are vibrant and video looks fantastic although the glossy finish’s propensity for reflections won’t be appreciated by all. It did a decent job of repelling fingerprints though. It offers 10-point multi-touch functionality and comes with a small digital stylus which gets housed and charged in the rear of the chassis.

The stylus charges in a cavity at the back of the slim chassis.

Beneath it is a keyboard with interesting-looking keys that have a slight, stylish curve to their undersides. They are also extremely low travel – barely a millimetre. While this makes sense as the keyboard’s surface doubles as the base of the tablet form factor, it makes for very harsh typing. We found that any extended periods of typing made our fingertips hurt, like we’d been tapping them repeatedly on concrete.  

The very-low travel keyboard is very hard and harsh to type on.

Below the keyboard is a functional touchpad and (to the right) a fingerprint reader that’s backed-up by a secure, TPM-2 module. The HD webcam which sits above the screen, impressively fits in a sliding privacy cover (you’ll need fingernails to operate it). However, neither it nor the fingerprint reader are Windows Hello compatible. The webcam is flanked by far-field digital microphones which help with voice activation from across a room, though. 

The 360 Hinge keeps the tablet from flapping open (mostly).

When flipped into tablet mode, the Yoga 360 hinge does a decent job of keeping the sides together in one unit. It’s worth noting that the rotating Dolby Atmos speaker beneath the screen faces both inwards and outwards and it provides surprisingly rounded sound for such a thin laptop.

The Yoga's hinge and speaker perform impressively.

Connectivity 

Connectivity is minimalist to the point of being severely restricted. On the left there is a USB 3.1 Gen 2 Type-A port plus two USB 3.1 Gen 2 Type-C/Thunderbolt 3 ports (one of which is used for charging) plus a 3.5mm audio jack. On the right, there’s... nothing. Wi-Fi 6 and BlueTooth 5 are included internally but you’ll need a bunch of dongles for Ethernet, HDMI, VGA connections and such like. A Thunderbolt 3 dock costs a whopping $430. 

Srlsy?

Performance 

The quad-core, Hyperthreaded Intel Core i7-1065G7 CPU idles at 1.3GHz and turbo boosts to 3.9GHz. It’s flanked by 16GB of soldered LPDDR4X-3733 RAM and a 512GB NVMe hard driveThese combined to score 4,666 in PCMark 10 which, UL Benchmark informs us, is just above average for a typical 2020 office laptop. The Intel Iris Plus graphics aren’t built for gaming as lowly scores of 1,397 (6fps) in 3DMark’s Fire Strike Extreme and 966 (5fps) in Time Spy attest. However, 9,462 points (40fps) in Sky Diver and 10,519 (60fps) in Night Raid show that it’s capable of playing casual and uncomplicated, competitive games. The score of 714 in Cinebench’s R15 rendering tests tells us that the quad-core processor isn’t the best for hardcore renderers though. 

Portability 

The 60Whr battery is quoted as having a 17.5-hour battery life. It ran PCMark 10’s Modern Office test for 15 hours and seven minutes, which is slightly short but very impressive nonetheless. Lenovo also boasts of its ability to provide two hours charge after 15-minutes of charging. 

With a weight of just 1.3kg it’s not heavy and the robust build quality gives us confidence that it will brush off rough handling (so long as the screen isn’t exposed). 

Conclusion 

At $3,699 it’s very expensive although most purchasers will likely use LenovoPro’s business payment and leasing options. While we’re disappointed with the connectivity and didn’t like the harsh keyboard, for those who need to frequently use it as a tablet form factor, it’s an attractive proposition.
