    Lenovo 15-inch Yoga C940 review: Like having an all-in-one desktop and laptop in one

    Sarah Tew/CNET
    The 15.6-inch Lenovo Yoga C940 is the center floor between ultraportable two-in-ones and the bigger screens and sooner efficiency of desktop alternative laptops. Its slim physique makes it extra transportable than older 15.6-inch notebooks and, whereas it is round 4.4 kilos (2 kg), it is nonetheless lighter in your lap and in your bag, too. With the larger show, although, you’ve got obtained extra room to work than with a small two-in-one just like the 13.3-inch HP’s Spectre x360, however with out dropping the flexibleness of the design. And the C940’s six-core processor and discrete graphics enables you to do stuff you merely cannot with a smaller two-in-one.

    LikeSlim and trendy for a desktop alternative.Excellent efficiency for work and leisure.

    Don’t LikeDisappointing port assortment given its measurement.Memory cannot be upgraded post-purchase.

    Since it is a premium two-in-one crammed with higher-end elements, the 15-inch C940 is not cheap, beginning round $1,400. The one I reviewed is presently out there from Best Buy at that value, however appears to recurrently promote for $1,540. If you do not want the two-in-one flexibility otherwise you care about efficiency greater than design, there are actually different choices. But, if it sounds interesting to have one thing akin to a small all-in-one desktop that is additionally a laptop computer, a big sketchpad or digital whiteboard and a gaming PC, the Yoga C940 is well worth the value. Lenovo Yoga C940-15IRH

    A contemporary desktop alternativeWith a two-in-one this measurement, certainly one of my favourite methods to make use of it’s in stand mode with the keyboard confronted down and the show ahead. Attach a keyboard and mouse and you have what’s basically an all-in-one desktop with a 15.6-inch show. The C940 has two Thunderbolt 3 ports and one USB-A port, which suggests you may possible want a dock or adapter if you wish to add an exterior show or two to your setup. It’s disappointing there isn’t any HDMI out, Ethernet or SD card slot.

    Don’t need to connect a keyboard and mouse? The C940’s are simply nice to make use of full time. The backlit keyboard has sufficient journey and suggestions to make contact typing snug, although some would possibly discover it mushy in comparison with the corporate’s ThinkPad keyboards just like the X1 Yoga’s. Lenovo squeezed in a quantity pad and media controls, too. The precision touchpad is clean and responsive with an outlined click on to it. The included lively pen is small however shops within the physique.

    The show is nice, too, although it may stand to be calibrated out of the field for higher shade. At 400 nits, it is shiny sufficient that can assist you see previous gentle reflections, however working outdoors will nonetheless have you ever adjusting your viewing angle. Like final 12 months’s 14-inch C930, this show is pen-enabled, and Lenovo contains an lively pen that expenses in its personal storage constructed into the physique’s proper aspect. It’s small, so you may most likely need to spring for a full-size pen when you plan to jot down or draw for lengthy durations of time. Considering the display screen measurement and general weight, the 15-inch C940 is awkward to make use of as a handheld pill. That mentioned, it is completely nice to make use of on a desk or lap, and I appreciated having the additional room for notes and sketches. Also, put in tent mode, you’ve got obtained a number of room to make use of it as a digital whiteboard or give a presentation. 

    Another function carried over from the C930 is the soundbar hinge. Regardless of the place you are utilizing the display screen in, you get clear audio. However, they do sound a bit skinny when you do not activate the Dolby Atmos app. With it you’ll be able to rapidly tune the audio for no matter you are listening to — music, film, sport, voice — or you’ll be able to arrange three private profiles or set it to Dynamic and let the software program do the guesswork. You’ll nonetheless need good headphones or exterior audio system for thumping bass, however for normal listening to music or watching movies, this setup works very well.

    Performance for every partThis C940’s mixture of a six-core processor and lower-end midrange discrete graphics can deal with productiveness duties to picture and video modifying. And sure, it is completely able to gaming at medium to excessive settings relying on the title. You will need to be sure to get as a lot RAM as you’ll be able to afford, although, because it’s soldered on and cannot be elevated later. If you are going to skimp, do it on storage since that may be upgraded simply sufficient. The reality that you simply get this efficiency in a slim two-in-one is fairly nice, but it surely does often require the followers to go full blast to maintain issues cool. They aren’t significantly loud, however will not miss them. However, if you would like, Lenovo’s included Vantage software program enables you to or the laptop computer resolve the right way to cool.

    With the discrete graphics, the C940 requires a bigger energy brick than different Yogas that use built-in graphics. (This system additionally cannot be charged by way of USB-C, by the best way.) Battery life was truly longer than I anticipated, getting 9 hours, 44 minutes on our streaming video take a look at. With normal use, I may get about 6 to 7 hours of use, however your mileage will differ relying on what you are doing and you will positively need to plug in for something demanding like gaming. And there’s a Rapid Charge function you’ll be able to activate to get the battery as much as 80 % in an hour. If you’ve got been on the fence about getting a two-in-one or sticking with a standard clamshell laptop computer, the 15-inch Lenovo Yoga C940 strikes a contented medium. Also, because of its discrete graphics, it is a superb compromise for many who need one thing that is a productiveness and leisure machine that additionally contains PC gaming. Geekbench 4 (multicore)
