Lenovo Yoga C740-14IML Convertible Review: Top-tier Looks, Mid-tier Price

Affordable without feeling cheap. The Yoga C740 offers a lot on all fronts relative to the sub $1000 asking price. Cut corners have been carefully executed to make the system feel as close as possible to the pricier flagship Lenovo Yoga C940.

The 14-inch Yoga C740-14 is Lenovo's mid-range convertible laptop that sits in between the lower-end Flex 14 and higher-end Yoga C940-14. It incorporates many of the same features as found on the Yoga C940-14 while dropping some of the more luxurious options as we will detail below in order to keep prices low.

Current SKUs range from the Core i5-10210U CPU with 512 GB SSD and 8 GB of RAM for $799 up to the Core i7-10510U CPU with 1 TB SSD and 16 GB of RAM for $1000. All configurations are fixed at 1080p with no hexa-core Core i7-10710U options, 4K UHD, or Ice Lake CPUs.

The Yoga C740-14 competes with other mid-range to high-end 2-in-1 laptops like the Asus ZenBook Flip 14, Dell XPS 13 7390 2-in-1, Acer Spin 7, and the HP Envy x360 13.

Case

The chassis shares the same style as its larger 15.6-inch Yoga C740-15 sibling but in a more travel-friendly 14-inch size. The smooth aluminum surfaces and clean look seem inspired by more expensive Ultrabooks like the Yoga C940 or the HP Spectre series. Rigidity is not as strong, however, as twisting the base will cause more warping and creaking than on the aforementioned alternatives. Even so, the slight flexing is definitely not of any concern and nowhere near as "budget" as what we experienced on the HP Pavilion x360 series.

When compared to the pricier Yoga C940-14, some physical features had to be cut in order to reach a lower price. The hinges, for example, no longer house speakers and they even feel slightly weaker this around. The notched webcam along the top edge and the integrated active stylus on the Yoga C940 have both been omitted as well for a more straight-forward design. Fortunately, the webcam privacy slider remains and chassis quality is excellent on our store-bought unit with no unintended gaps or noticeable defects.

Overall size is within 1 to 2 mm of the pricier Yoga C940 in each dimension. Even the weight between the two systems are nearly identical at about 1.4 kg each. We find the 14-inch form factor to be the most practical when it comes to convertible laptops as screen size is larger than the 13.3-inch while not being as unwieldy as heavier 15.6-inch solutions like the Lenovo Yoga C740-15 or the HP Spectre x360 15.

Base feels weaker than the Spectre x360 13 and on par with the XPS 13 7390 2-in-1

Connectivity

Port options are limited to USB Type-A and two USB Type-C ports. Both of the Type-C ports are capable of recharging and DisplayPort for added versatility. There is no Thunderbolt 3 support as Lenovo is reserving this feature for its costlier Yoga C900 series instead.

Communication

WLAN is provided by an Intel 9560 for Wi-Fi 5 speeds. Average transfer rates are quite close to the latest AX200 Wi-Fi 6 cards even when connected to the same high-end Netgear RAX200 router and 2.5 Gbps server line. We didn't experience any connectivity issues during our time with the test unit.

Maintenance

The bottom panel requires a T5 Torx wrench and a sharp edge to remove. Once inside, users have direct access to the M.2 2280 SSD, WLAN module, and batteries. RAM is not upgradeable.

Accessories and Warranty

There are no extras in the box other than the AC adapter and some paperwork. A cleaning cloth, protective sleeve, or stylus would have been neat additions.

The standard one-year limited warranty applies. Like HP and Dell, Lenovo offers a wider range of extension options than other OEMs.

Input Devices

Keyboard

Lenovo offers some of the better keyboards on a laptop in terms of tactility and travel throughout its ThinkPad series. Unfortunately, we cannot say the same for the Yoga series. The keyboard here is closer to a cheaper IdeaPad offering than on a renowed ThinkPad as keys are shallow in travel with relatively weak feedback when pressed. The keyboards on the XPS 13, Spectre x360 13, Surface Laptop 3, or MateBook X Pro are firmer for a more satisfying typing experience. On the plus side, clatter is quiet when typing likely due to the soft key feedback.

Two-level white backlight comes standard to illuminate all keys and their secondary labels.

Touchpad

The clickpad (~10.5 x 7 cm) is slightly smaller than the ones on both the 13.5-inch Surface Book 3 (~11.5 x 7.6 cm) and 13.4-inch XPS 13 7390 2-in-1 (~11.3 x 6.8 cm). Gliding across the surface is smooth with almost no sticking even at slow speeds. We encountered no cursor jumping or stalling issues no matter the movement speed.

The integrated mouse keys are average in feedback with an audible click when pressed. It's satisfactory overall, but could have been firmer. Dragging and dropping is still more challenging when compared to laptops with dedicated mouse buttons like the ThinkPad T490.

Display

The CMN N140HCE-ET2 panel can be found on no other laptop in our database. The CMN N140HCE series in general, however, is common amongst many 14-inch laptops including the Asus ZenBook UX3410, MSI PS42, ZenBook UX3430, and Lenovo's own ThinkPad T460 and T460s. Though display quality is still very good, there are a few drawbacks that put it a step or two below higher-end systems like the XPS 13 or Yoga S940. Firstly, the display is dimmer at around 300 nits compared to 500 nits or higher on the the two aforementioned alternatives. Secondly, colors are not as well calibrated out of the box. And lastly, there is a small layer of graininess on the display despite it being a glossy panel. Texts and images are thus slightly less crisp than they could have been.

Response times are typical for an Ultrabook. Ghosting is noticeable but not intrusive since the system was not designed to play fast-paced games. Backlight bleeding, however, could have been better especially around the bottom corners as shown by our screenshot below.

Color space covers approximately 98 percent of sRGB or 64 percent of AdobeRGB to be indicative of a high-end panel. Lesser laptop families like the IdeaPad series or Inspiron series tend to cover ~60 percent of sRGB only for shallower and less accurate colors.

Further measurements with an X-Rite colorimeter reveal a warmer-than-expected color temperature with mediocre RGB balance. Once we calibrated the display ourselves, its average grayscale deltaE improves sharply from 6.4 to 1.2 for more accurate colors overall. We recommend applying our calibrated ICM file above or calibrating the unit yourself to get the most out of the display.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
36.8 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 9.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 93 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 29 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 27030 Hz ≤ 67 % brightness setting

The display backlight flickers at 27030 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 67 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 27030 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17067 (minimum: 5 - maximum: 2500000) Hz was measured.

Outdoor visibility is merely average and could have been better for a convertible laptop since owners are more likely to use these 2-in-1 systems on-the-go. Colors become washed out on an overcast day and glare becomes prevalent when under shade. A brighter display would have minimized these issues, but you'll have to invest in the pricier Yoga C940 for that.

Performance

Configurable options feel limited as is common on convertible subnotebooks. Users can choose between the Intel 10th gen Comet Lake-U Core i5-10210U or Core i7-10510U CPU with no other display or GPU options. If you want something with more graphics potential, then consider the Ice Lake-powered Dell XPS 13 2-in-1, Yoga C940, or Spectre x360 13 instead. We're hoping that Lenovo will add AMD Ryzen options in the future.

DDR4 RAM is soldered up to 16 GB. We experienced DPC latency issues even with the wireless disabled.

 

Processor

Opting for the Core i5-10210U instead of the higher-end Core i7-10510U configuration will incur a 15 to 20 percent performance deficit according to CineBench multi-threaded benchmarks. With the exception of the more impressive hexa-core Core i7-10710U, the 10th gen Comet Lake-U series brings only minor performance benefits over the 9th gen Whiskey Lake-U series and even the 8th gen Kaby Lake-R series as detailed here. The older Core i5-8250U, for example, is only about 15 percent slower. The higher-end Yoga C940-14 with the Ice Lake Core i7-1065G7 performs more in line with the Core i7-10510U than our i5-10510U.

Turbo Boost sustainability could be better. When running CineBench R15 Multi-Thread in a loop, the initial score of 675 points drops to about 540 points over time to represent a 20 percent performance deficit when the CPU is stressed. Results are very close to what we observed on the ThinkBook 15 equipped with the same Core i5 CPU.

See our dedicated page on the Core i5-10210U for more technical information and benchmark comparisons.

System Performance

PCMark results are comparable to other laptops with the Core i5-10210U and even those equipped with the Core i7-1065G7 like Lenovo's more expensive Yoga C940. Ice Lake has a superior integrated Iris GPU, however, and so our Comet Lake system falls behind in the GPU-heavy Digital Content Creation benchmark. Its PCMark Essentials score is particularly high likely due to the fast Samsung SSD PM981a NVMe SSD.

Storage Devices

Lenovo has equipped its Yoga C740-14 with the same Samsung PM981a NVMe SSD as found on the Yoga C940-14. Meanwhile, the ThinkBook 15 gets the faster Samsung PM981 instead. Average performance is faster than on the older Toshiba BG4 or cheaper SK Hynix BC501 that Microsoft uses for the Surface Laptop 3. There are no secondary internal drive options.

GPU Performance

Graphics performance has barely changed from the older Kaby Lake-U series since the Comet Lake-U series uses the same outdated integrated UHD Graphics 620 GPU. As a result, 3DMark benchmarks are only about 10 percent faster than the average UHD Graphics 620 in our database compared to over 100 percent on the newer Ice Lake Core i7-1065G7 Iris Plus GPU or the competing integrated Radeon RX Vega series. This is an Ultrabook more for 4K video playback rather than any sort of gaming or editing.

See our dedicated page on the UHD Graphics 620 for more technical information and benchmarks.

Emissions

System Noise

The cooling solution consists a single ~50 mm fan and a short copper heat pipe. Fan noise is quiet and essentially inaudible during low loads at up to 31 dB(A) against a background of 29 dB(A). Running the first benchmark scene of 3DMark 06 induces a fan noise of 32.6 dB(A) towards the end of the test to be comparable to what we recorded on the Yoga C940. Fan noise stabilizes at 39 dB(A) when running Prime95 for long periods.

Perhaps the worst aspect of the fan is that it is higher-pitched than most other Ultrabooks. Thus, fan noise is more noticeable when it begins to ramp up even though the system is generally quiet under most low to medium processing conditions.

We can notice no electronic noise or coil whine from our test unit.

Temperature

When idling, the left half of the system becomes warmer than the right half. We're able to measure a hot spot of about 29 C on the bottom of the laptop nearest the SSD and WLAN card. When running heavy loads, however, hot spots will shift to the center of the laptop due to the positioning of the processor. The new hot spots can be as warm as 38 C to 42 C compared to 43 C to 47 C on the thinner Yoga C940 or 46 C to 51 C on the XPS 13 7390 2-in-1. The palm rests and most of the keyboard remain cooler.

Stress Test

We stress the laptop with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed boosting to 3.7 GHz for just a few seconds until hitting a core temperature of 97 C. Thereafter, clock rate and temperature drop to 2.8 GHz and 81 C, respectively, for just a few minutes. The CPU eventually stabilizes at 2.1 to 2.2 GHz and 72 C.

Running on battery power will not limit performance. A 3DMark 11 test on batteries returns a final score that is within 1 percent of what we recorded when on mains.

Speakers

Audio quality is good for a 14-inch convertible but inferior to the speakers on the more expensive Yoga C940. Our pink noise measurements show the speakers of the Yoga C740 to be quieter with slightly less powerful bass. While high volume settings will not introduce any static, the palm rests will vibrate slightly to the touch.

Energy Management

Power Consumption

Idling on desktop demands between 3 W and 8 W depending on the brightness setting and power profile compared to 5 W and 12 W from the 4K UHD Yoga C940. We're able to record a temporary maximum of almost 66 W from the small (~11 x 4.8 x 3 cm) 65 W AC adapter when initiating Prime95 and FurMark. Expect consumption to be around 37 W to 42 W when running high sustained loads like gaming.

First scene of 3DMark 06. Consumption is highest during the first few seconds at about 50 W before eventually falling to about 40 W

Battery Life

Small 65 W USB Type-C adapter
Small 65 W USB Type-C adapter

Battery capacity is smaller than on the Yoga C940 (60 Wh vs 51 Wh). Even so, runtimes are impressive at just over 9 hours of real-world WLAN use to be above average for its convertible category. Results are longer than what we recorded on the Yoga C940-14.

Charging from empty to full capacity takes 2 to 2.5 hours.

Verdict

In review: Lenovo Yoga C740-14IML
In review: Lenovo Yoga C740-14IML

Lenovo has positioned the Yoga C740-14 quite well in the current market. It's hundreds of dollars less than both the Dell XPS 13 7390 2-in-1 and Asus ZenBook Flip 14 when configured with the same RAM and storage capacities while offering a larger screen size than the HP Spectre x360 13. Best of all, the Yoga C740 retains a high quality look and feel that most users have come to expect from a flagship model even though it retailers for well under a grand. It's a great in-between option if you don't care about 4K, Thunderbolt 3, or Ice Lake features.

There is still a list of drawbacks that add up. The moderate uneven backlight bleeding, relatively dim display, poorly calibrated colors out of the box, spongy keyboard keys, and high-pitched fan noise when under load make the overall experience not as solid as it could have been. Still, it's a well-rounded convertible given the price point and it's definitely worth the extra investment over something like the horrid HP Pavilion x360 or cheap VivoBook Flip.

The Lenovo Yoga C740-14 is one of the better convertible laptops in its mid-range category because it looks and feels closer to the pricier high-end models without costing any more.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
