At first look, it’s simple to dismiss this explicit mannequin of Lenovo’s Yoga C640, a Best Buy unique with a comparatively anemic dual-core i3 Comet Lake CPU, a puny 128GB SSD, and a $600 price ticket. That mentioned, this glossy convertible (formally the Yoga C640-13IML) has an ace up its sleeve: a beefy battery that simply goes, and goes, and goes.
While this made-for-Best Buy system isn’t an awesome decide for customers seeking to course of 4K movies or crunch large numbers (there are different Yoga C640 configurations higher suited to such CPU-intensive duties), it might be an awesome match for customers in search of a flexible 2-in-1 that may go all day lengthy with out an AC wire.
Configuration
Lenovo presents three versions of the Yoga C640-13IML (we’ll simply name it the Yoga C640 from right here on out) on its web site, together with a $850 model (or $770 after reductions) with a 10th-gen Core i5-10210U processor, 8GB of DDR4 RAM, and a 256GB strong state drive, and a $1,000 mannequin ($910 with rebates) with the identical RAM and SSD however an upgraded i7-10510U CPU. There’s additionally a $1,050 configuration that ups the RAM on the Core i7 model to 16GB. All three fashions include the identical touch-enabled 13.3-inch Full-HD IPS show.
Our assessment model (81UE000WUS) of the Yoga C640-13IML isn’t listed on Lenovo’s web site; as an alternative, it’s a $600 Best Buy unique that’s significantly cheaper (and, consequently, much less highly effective) than the opposite three fashions.
Here are the main points:
- CPU: Dual-core Intel Core i3-10110U (Comet Lake)
- Memory: 8GB DDR4
- Graphics: Integrated Intel UHD Graphics
- Storage: 128GB SSD
- Display: 13.3-inch 1920×1080 IPS, touch-enabled
- Webcam: 720p, dual-array microphone, bodily digicam shutter
- Connectivity: One SuperSpeed USB 5Gbps (previously often called USB 3.2 Gen 1) Type-C port, two SuperSpeed USB 5Gbps (previously often called USB 3.2 Gen 1) Type-A ports, combo audio jack
- Networking: Wi-Fi 5 (802.11ac)
- Biometrics: Fingerprint reader
- Battery capability: 60 Watt-hour
- Dimensions: 12 x 8.1 x 0.7 inches
- Weight: 2.88 kilos (3.22 kilos with AC adapter)
Overall, this a typical configuration that we see in price range laptops. The dual-core 10th-gen Comet Lake Core i3 CPU is completely able to on a regular basis computing duties resembling internet shopping, Office, and light-weight photograph enhancing, though it’ll begin to chug relating to demanding multi-core operations like video processing or crunching databases. The 8GB of RAM presents a good quantity of headroom for multitasking or juggling a number of browser tabs.
The 128GB SSD will get cramped awfully quick. Once you take into consideration Windows 10 and different apps pre-loaded onto the C640, the drive solely has about 77GB of free house left. If you retailer so much domestically, you may need to spend money on an exterior exhausting drive or cloud storage.
Physically, the 0.7 inch-thick and a pair of.88-pound C640 is about the identical dimension and weight as different 2-in-1 programs in its class. The fingerprint reader is at all times a pleasant bonus. WWhile Wi-Fi 5 networking is normal for laptops on this worth vary, simply do not forget that you received’t be capable to reap the benefits of the improved velocity and effectivity options supplied by cutting-edge Wi-Fi 6 routers.
We’ve left the most effective for final, although: particularly, the Yoga C640’s 60 Watt-hour battery, which bodes nicely relating to battery life. Later on, we’ll put the battery to the take a look at and see whether or not it lives as much as its promise.
Design
The Lenovo Yoga C640 boasts the identical general design scheme as Lenovo’s different Yoga fashions, together with its angled entrance edge, flat sides, and the signature Yoga 360-degree hinge. Thanks to the hinge, you’ll be able to swivel the show all the best way round and use the C640 as a pill, tent it on a desk or tabletop, or sit it keyboard-down with the show angled up for kiosk mode.
The Lenovo Yoga C640’s 2-in-1 design allows you to swivel the show all the best way round for pill use, tent it on a tabletop, or sit it keyboard-down with the display screen tilted up.
The C640’s sandblasted aluminum shell did a pleasant job of resisting fingerprints, though I may additionally spot faint greasy hand smudges right here and there. While the C640’s flat, almost featureless lid (save for the Yoga brand) feels clean to the contact, the underside half of the chassis has a slight rubberized really feel, which helps to maintain the laptop computer from slipping out of your hand.
A few different design options price mentioning embrace the Yoga C640’s energy button, which sits on the appropriate aspect of the laptop computer close to the hinge, a place that makes it powerful to press by chance.
Ben Patterson/IDGThe bodily digicam shutter on the Yoga C640 is a pleasant bonus for a $600 laptop computer.
Also worthy of word is the “TrueBlock” privateness shutter for the 720p webcam sitting within the show’s high bezel. The shutter is so delicate that it’s simple to overlook, and it doesn’t supply any visible cues whether or not it’s open or shut. That mentioned, the shutter is straightforward to slip (I had a a lot more durable time coping with the shutter on the Yoga C640’s pricier cousin, the Yoga C740), and given this laptop computer’s price range worth vary, it’s a uncommon deal with to get a webcam shutter in any respect.
Display
Any price range laptop computer show whose brightness measures north of 250 nits (or candelas) is a plus in our e book. All too usually, we see discount laptops with screens that may’t even hit that low-water mark.
Luckily, the Lenovo Yoga C640’s full-HD show, which is surrounded by slim bezels alongside the highest and sides with a chunkier bezel on the underside, is fairly vivid for a laptop computer in its worth vary, measuring 305 nits in response to our readings. Granted, we’ve seen loads of laptops with shows that measure nicely north of 300 nits (as in 400 and even 500 nits, in some instances), however they’ll typically price you a whole bunch greater than the Yoga C640 does.
The Yoga C640’s IPS (in-plane switching) show delivers strong viewing angles. The display screen dims solely barely when seen from the perimeters or the highest or backside, with no indicators of inverse colours. The touch-enabled show additionally did a pleasant job of responding to my faucets and swipes.
Keyboard, touchpad, audio system, and extras
I’ve been impressed by the texture of the keyboards on different Lenovo Yoga fashions, and the Yoga C640’s keyboard isn’t any exception. They’re a pleasure to kind on, with a slight concave design, simple discovery, and beneficiant journey (that’s, the space {that a} key strikes when it’s pressed). Each keystroke delivers a crisp, tactile bump, with a refreshingly springy rebound. They keyboard presents two-step backlighting, together with hotkeys for quantity, mic mute, airplane mode, Windows lock, and display screen brightness. There aren’t any media playback hotkeys, sadly.
Ben Patterson/IDGThe Lenovo Yoga C640’s backlit keyboard is a pleasure to kind on, whereas the touchpad did a pleasant job of rejecting false inputs. (And sure, that is a Dolby Atmos brand.)
The Yoga C640’s touchpad sits just under the house bar, placing it barely left of heart. I had little bother swiping and clicking the touchpad, and I by no means seen any jitteriness from false inputs. Even once I deliberately brushed my palms towards the underside corners of the trackpad, the cursor remained rock-steady.
The Yoga C640’s upfiring audio system sounded fairly good for laptop computer audio system, with a good quantity of element and even some delicate bass response. Even higher is the Yoga C640’s assist for Dolby Atmos, an object-based sound format that enables for exact sound placement in a 3D soundstage. Dolby Atmos is usually considered an audio format designed for theaters and residential audio setups with in-ceiling audio system, however Atmos is discovering its approach into loads of units with solely stereo audio system, together with telephones and laptops. Of course, the Yoga C640’s stereo audio system can’t method the constancy of a correct house theater and even exterior pc audio system, however the laptop computer’s Atmos-enabled drivers handle to ship strong audio with an impressively vast and detailed soundstage—nicely, for laptop computer audio system, anyway.
Ports
The Lenovo Yoga C640 has a middling collection of ports. On the left aspect, you get the primary of two USB SuperSpeed 5Gbps (previously USB 3.2 Gen 1) Type-A ports, together with a combo audio jack and a barrel-shaped energy port.
Ben Patterson/IDGThe left aspect of the Yoga C640 incorporates a USB SuperSpeed 5Gbps Type-A port and a combo audio jack.
On the appropriate aspect sits the second USB SuperSpeed 5Gbps Type-A port, together with a USB SuperSpeed 5Gbps Type-C port.
Ben Patterson/IDGA second USB SuperSpeed 5Gbps Type-A port sits on the appropriate aspect of the C640, together with a USB SuperSpeed 5Gbps Type-C port. No media card reader, nonetheless.
While we’re at all times blissful to see a pair of USB Type-A ports (good for connecting, say, a mouse and a printer), together with a USB-C port (useful for newer exterior exhausting drives), we’re dissatisfied by the dearth of a reminiscence card reader or an HDMI port. Also lacking is a slot for a laptop computer safety cable. You’ll possible need to spend money on a USB-C hub to increase your connectivity.
Keep studying for the efficiency benchmarks and that loopy battery life.
