The ports on the other side include one USB-A, two Thunderbolt USB-Cs and a headphone jack.The Lenovo Yoga C940 comes with two display options: Full HD and UHD (4K). I didn't notice any noise from the cooling fan even while browsing with multiple tabs open, though I did hear the fan spool up when the Yoga was installing apps and software updates.My test unit also featured an upgraded 4K (3,840-by-2,160-pixel) display with a rated brightness of 500 nits, which is more than adequate for viewing in a brightly lit office. Both are easy to handle, although if you’re planning to use yours in tablet mode regularly, the 14-inch variant will be more comfortable over longer periods.Ports remain unchanged from the C930, with a pair of USB-C 3.1 Gen 2 ports with Thunderbolt 3 compatibility on one side, and a legacy USB-A 3.1 Gen 2 port on the other, alongside a 3.5mm headphone jack.
The Yoga C940 uses subtle curves all the way around the device and even leaves one side completely absent of ports for a cleaner look. That said, it's absolutely fine to use on a table or lap, and I appreciated having the extra room for notes and sketches. Lenovo is taking full advantage of that broad range of chips throughout its product range, but the C940 keeps things relatively simple by only offering two generations and it splits them by size. Note that neither display offers pro-level features such as OLED technology, HDR, or wide color gamuts, but colors still looked brilliant and text crisp during both day and night testing of the C940.If a built-in stylus, extra screen real estate, and a USB Type-A port matter more to you than a bit of extra bulk, though, the Yoga C940 is actually a better choice than its XPS and Spectre competitors. Any score above 4,000 in this test is excellent. They aren't particularly loud, but won't miss them. Two minute review.
We would have liked to see Lenovo employ the webcam and screen-bezel miniaturization strategy that HP and Dell have, or create a radically lighter design like HP's Dragonfly.My anecdotal experience largely matched these benchmark results. These results are standard for a modern day ultrabook, although not quite accurate enough for professional artists looking to take full advantage of the stylus functionality.Our review model came equipped with the top specs you can get on the Yoga C940 – a 10th Gen Intel Core i7 processor, 16GB of RAM and a 512GB SSD.It feels strange to be referring to a device that’s around 15mm thick as chunky – however, it’s true.Your eyes will likely be drawn to the hinge of the device that runs along much of the join between the laptop’s screen and keyboard.
This design is fine – the hinge has the look of a speaker grille and houses two tweeters to support the rest of the sound system on the underside of the laptop. I tend to prefer higher-resolution panels on convertible and detachable PCs, since I find individually noticeable or detectable pixels to be more annoying when the device is in an orientation other than the conventional laptop mode.That the Yoga C940 lasted more than 12 hours in our unplugged-video-playback battery test is a significant achievement. Also, thanks to its discrete graphics, it's an excellent compromise for those who want something that's a productivity and entertainment machine that also includes PC gaming.With its 15.6-inch display, discrete graphics and slim, two-in-one design, the C940 has the performance and flexibility to meet your laptop and desktop needs.CNET también está disponible en español.With the discrete graphics, the C940 requires a larger power brick than other Yogas that use integrated graphics.
The Yoga S940 touts a Dolby Atmos speaker system, although that moniker may lead you to expect more. (This system also can't be charged via USB-C, by the way.)
