Lenovo has introduced its new-generation top-of-the-range Yoga C940-series 14-inch convertible notebooks. The new breed has been equipped with Intel’s 10th Generation Ice Lake processors along with plethora of new improvements which include better connectivity as well as power efficiency.

Being Lenovo’s flagship convertible PC for consumers and (to some degree) creative professionals, the Yoga 9-series has evolved quite significantly over the years. While the original Yoga 900 featured a 13.3-inch display of a 3200x1800 resolution, the all-new Yoga C940 comes with a larger HDR-supporting 14-inch LCD featuring a Full-HD or Ultra-HD resolution as well as 400/500 nits brightness. Furthermore, despite the fact that Yoga 9 displays are now larger, their overall dimensions and thickness is lower, making the systems more compact. What remained intact are all-metal CNC-machined chassis (now with twice polished aluminum lid) as well as signature 360° watchband hinge.

Enabling the Lenovo Yoga C940 14-inch convertibles are Intel’s 10th Generation Core i5/i7 Ice Lake processors with advanced Iris Plus integrated graphics and a revamped motherboard design featuring a smaller footprint that allows to make actual systems smaller. To make the Yoga C940 more appealing, Lenovo equipped it with its special Intelligent Cooling Mode (activated by pressing FN+Q) that automatically adjusts performance and cooling based on workloads. The CPUs are paired with 8, 12 or 16 GB of LPDDR4X memory as well as an NVMe/PCIe solid-state storage subsystem of up to 1 TB (see exact specifications in the table below).

As far as connectivity is concerned, the new Yoga C940 14-inch comes with Wi-Fi 5 or Wi-Fi 6, two Thunderbolt 3 ports, as well as one USB 3.1 (Gen2) Type-A port. Furthermore, the Yoga C940 also has a Dolby Atmos-supporting rotating soundbar, a far field microphone array (to support Alexa, Wake on Voice and similar functionality), a fingerprint reader, and a webcam with Lenovo’s TrueBlock privacy shutter.

Because of the new processor and system design, the Lenovo Yoga C940 is now 14.1 mm thick (down from 14.5 mm) and weighs starting at 1.35 kilograms (down from 1.38 kg). While Lenovo does not mention battery capacity of the machine, it says that the Full-HD model can work for up to 17.5 hours (up from 14.5 hrs), whereas the Ultra-HD laptop can work for up to 9.5 hours (up from 9 hrs), which suggests that this device may qualify under Intel's Athena programme.
