Lenovo Yoga C940 review


Pros

  • Arrow-fast PCIe/NVMe data storage ensures a fast system
  • Quiet operation, even at higher room temperatures
  • Very good battery life & Excellent picture and sound quality

Cons

  • More expensive than Yoga C740

When it comes to the best consumer notebooks, the eyes are mostly directed to Dell and HP. The flexible Lenovo Yoga C940 doesn’t have to hide from anyone else. Only one detail disappoints.

One thing is initially noticeable in the Lenovo Yoga C940-14IIL: that it’s hardly noticeable. The laptop is also a completely quiet representative of its kind, with an inconspicuous iron grey finish.

This hasn’t been the case with any other notebooks I’ve tested with Intel’s 10th core generation. With the C940, I’ve only rarely heard the cooler, no matter if it was during normal office work, video streaming or gaming. Lenovo advertises with a “dynamic performance adjustment”, and it actually seems to work.

And that is no small thing. A constantly running or constantly switching itself on and off (like during my test in the sister model Yoga C640) gets on your nerves.

No matter whether it’s for concentrated work, a video conference in the home office or a relaxed series of shows on the couch. Such details are important, and Lenovo almost manages to get them through the bench in the Yoga C940.

Keyboard & Touchpad

Without a doubt, the keyboard is also part of it. Here the keys yield a little more than on a MacBook. The stroke is a little longer. But writing on it is a relief due to the solid workmanship. The discreet backlighting makes the keys easily recognizable both day and night.

All keys, even those for umlauts, are the same size (which isn’t a matter of course), which makes it much easier to write blindly. The cursor control keys can be felt just as faultlessly, with no disturbing up or down keys in the vicinity. So I hardly ever mistyped on the keyboard.

The fingerprint sensor is located on the far right underneath the keyboard and is as easy to reach as it is absolutely not disturbingly placed.

In practice, Windows didn’t always want to unlock the system immediately. That’s the same with most fingerprint sensors, so it’s not a special Lenovo problem.

Sound & Design

The Yoga C940’s touchpad makes the fingers glide very easily, hardly attracting fingerprints, and the pressure point is also pleasant. Merely, when I tapped on it, there were repeated misconceptions. Instead of simply selecting the text, for example, or right-clicking, the touchpad rather inserts something.

Another highlight is the rolling soundbar. Lenovo has accommodated it in the 360-degree pivoting Yoga C940 in the hinge – and you wonder why no one has thought of it before. There are some adventurous ways to put speakers in notebooks!

At the front, at the bottom, out the back… Speakers are better placed to the left and right of the keyboard. I consider Lenovo’s choice of hinge to be the best solution so far.

It also provides really good sound thanks to the Dolby Atmos technology with 3D effect. And there’s no wasted space anywhere else due to the installation in this very place.

Folded flat, the 360-degree notebook is 1.57 cm high and thus by far not the flattest of its kind (Dell XPS 13 for example: 1.48 cm), but still slim and transportable, even despite the not even so airy light weight of 2.97 lbs.

However, one has the feeling that every gram is very sensibly invested here. The Yoga C940 feels valuable and stable. The aluminium casing and even the hard plastic underside are perfectly finished.

Active Pen

You cannot open the notebook with one hand. You have to hold it with your other hand. But the hinge, which is not too smooth, looks as if it could easily survive tens of thousands of openings without damage.

Lenovo has used two long rubber strips on the bottom for the stand. This looks cleverer and a bit more robust than the four rubber plugs that are found under most notebooks.

Lenovo Yoga C940 test

You quickly turned the C940 into yoga mode. What’s great is that Lenovo has integrated a pen directly into the case, which also recharges automatically.

Drawing and typing is also excellent with it, although I have to admit that I hardly ever used this option. In most cases it was simply not necessary to use another input method thanks to the trackpad and touchscreen.

Display Quality

The picture quality of the 4K display is impeccable. Beautiful colors, fast response due to the interaction with Intel Iris Plus, which seems to work. In return, the display reflects quite strongly. You won’t be able to work well with it in the blazing sun.

And even with normal light on a cloudy day, you can often see yourself reflected in the display. After all, the maximum brightness of 400 to 500 cd/m2 (depending on the configuration) is above average.

Ports / Interfaces

Lenovo accommodates all connections on the left side. Although only 1x USB-A (3.1), 2x USB-C (3.1, 2nd gen) and a headphone-micro-combo are accommodated there, I didn’t have the feeling that something essential is missing there.

Most of the other notebooks I recently tested still offer an SD or micro SD card slot. But those who have both types of memory cards will anyway have long since bought a USB adapter for them in the course of their life in order to be prepared for all cases.

According to Lenovo, the two USB-C interfaces are Thunderbolt 3 with support for display port and power delivery. You can also recharge the notebook via one of the two USB-C interfaces.

Depending on the configuration of the Lenovo C940, you’ll also have Wi-Fi 5 (on a Core i5) or Wi-Fi 6 (Core i7). In the 14-inch version with a Core i7 I have, it’s Wi-Fi 6, and the connectivity is good, especially since I updated the drivers in Windows and Ubuntu (for which updates were available).

The Bluetooth 5.0 that I used provided reliable connections. I didn’t have dropouts during sound transmission (which are not uncommon under Linux).

Lenovo Yoga C940 ports

The fact that Lenovo only left an on/off button on the right side seems like wasted space. As I said: I don’t lack connections. But I would have liked that Lenovo had also installed another USB-C port on the right side, where I could charge the notebook.

Many manufacturers now offer this option, and it’s incredibly practical because you can charge your notebook from the side closest to the power outlet. In this case, unfortunately not possible.

Battery life

And then we would already be at the biggest horse’s foot of the Yoga C940, which is unfortunately related to it: the battery life. In my tests, the battery life barely exceeded 5 hours for normal office screen work under Windows and Linux.

This is little in 2020, and even too little compared to direct competitors (like Dell, HP and even Apple), which still manage 10 hours and more.

Lenovo Yoga C940 back view

Lenovo even talks about “up to 18 hours of battery life under Full HD” in its advertising, and in the case of the 4K screen of the configuration I have in front of me, still 10.5 hours. Unfortunately, I can’t confirm this even with only about 60 percent brightness.

The battery can be recharged in 2-3 hours during operation, so a bit of patience is also needed here.

Verdict

The Lenovo Yoga C940-14IIL is a beautiful notebook that lets the user work in peace with great Performance and an even better 4K Display.

Due to all the perks of the Yoga C940, the Lenovo Yoga C940 is ranking first vs Lenovo Yoga C740.

Ranking Second: Lenovo Yoga C740

Lenovo Yoga C740 review


Pros

  • High utility in everyday life through convertible function
  • Better Price than Yoga C940
  • Reliable fingerprint sensor

Cons

  • Touchpad is inaccurate and distorts when clicking
  • No HDMI ports

The Lenovo Yoga C740 is a convertible, with laptop, tablet, tent and stand-up mode, designed to meet the needs of the user. It is intended to be of particular service to creative people with an affinity for high tech. Whether the convertible keeps these promises, Techtestreport clarifies in the test.

The two Dolby Atmos loudspeakers integrated in the Lenovo Yoga C740 are supposed to provide radiant sound, while the Full-HD display is supposed to take care of the optical highlights.

The Intel Core i5-10210U is a CPU of the tenth generation and is supposed to provide the necessary performance with a boost clock of maximum 4.2 GHz. We have extensively tested Lenovo’s Convertible, which is available from $700.

Design & Keyboard

The Lenovo Yoga C740 features a sleek design that looks chic even without visual highlights. We especially noticed the precise fingerprint sensor, which not only works reliably but is also so well positioned that you only notice it when you use it.

The device is very stable and performs well in terms of torsional stiffness: the screen can hardly bend under the slight influence of force, and the display is securely integrated into the frame.

The illuminated keyboard offers a pleasant feeling while typing, without any rattling or other disturbing noises. The illumination can be adjusted in three levels.

The included Lenovo Active Pen is also high quality manufactured and feels good when in use. A program for handwriting recognition is integrated in Windows 10, so you can fill in every text field with the Active Pen instead of using the keyboard. W

hile the pen is easy and intuitive to use, it is only suitable for rough sketches. The reason for this is the lack of pressure strength recognition; a separate graphics tablet is required for precise drawing.

A drawing glove, with which one can put the hand on the display without operating it, is not included in the scope of delivery and has to be purchased separately.

Despite the high-quality workmanship, the touchpad doesn’t stand out well; it regularly distorts the mouse pointer to the right and left when clicking.

This is especially annoying if you accidentally close programs because of this. Opening the laptop is also difficult due to a missing notch. For gross motorists who have neither fingernails nor patience and are not particularly fond of fiddling, this point weighs heavily.

Display & Sound

The notebook also receives a point deduction for the display: All those who like to work outdoors must limit themselves to shady places. The reflective display looks very high quality, but provides for a barely legible screen in a bright environment.

While we didn’t even need the maximum brightness level with an older MacBook Air on the patio to be able to work properly, the Yoga C740 at maximum brightness level only gave us an idea of what could be seen on the screen.

At home or in the office, the brightness doesn’t cause any problems. The display’s size of 14 inches is completely sufficient for everyday work, although it naturally depends on the user’s personal preferences whether the size is popular or not.

The touch function is consistently precise and is a lot of fun despite the smaller display. With its intense colors, the display offers an overall excellent picture quality and thus scores further plus points.

The picture quality is also a big advantage for movie nights, and the razor-sharp picture contributes to a positive experience when watching videos. The Lenovo Yoga C740 doesn’t even need 4K resolution to shine – due to the small size of the screen, the 4K resolution wouldn’t come into its own anyway.

The laptop’s sound also knows how to thrill: music tracks and movie sounds come out of the Lenovo’s integrated speakers in good quality. Even the YouTube trend of “8D music” can be enjoyed with the speakers without a headset.

The position of the speakers, to the right and left of the keyboard, is a bit of an adjustment, though. This positioning is disadvantageous for use in the different modes.

The sound coming from behind sounds very muffled in tablet and tent mode. Here, the use of separately available headphones or a headset is recommended.

Performance

Everyday use in laptop mode runs pleasantly fluid. All tasks are completed quickly and the change between two applications is also smooth. During short periods of full load, the device delivers solid performance. The maximum boost clock is kept quite long by the CPU and thus delivers a good performance, especially when using Photoshop.

The fan is practically never audible with all these performances. When it turns up, it emits at most a soft but shrill whistling sound. However, the Lenovo Yoga C740 is not suitable for the continuous load of games or rendering very long videos.

It looks different in tablet mode. Here, we experience small hangs even when surfing and editing tables. Some applications, such as Steam or Photoshop, don’t even start. The touchscreen can also be used in other modes, so that in case of doubt you can also do without the tablet mode.

The very fast M.2 SSD with 512 gigabytes of memory ensures a lightning-fast system start and reduces the loading time of programs to a minimum.

Two RAM bars, each with 4 gigabytes of memory, have been installed as main memory. You can expect more RAM in this price category, but the maximum is exhausted relatively quickly in normal use.

The missing HDMI socket is also rather unusual and is often standard in competing products. Fortunately, a corresponding adapter can help. But the heart laughs again with the modern and fast connection technologies Wi-Fi 6 and Bluetooth 5.0.

Battery life & weight

Looking at the battery level creates positive feelings. Although there are even more power-saving alternatives to the built-in CPU, the Lenovo Yoga C740’s battery lasts longer than most competitors’. During a 12-hour workday, the battery only needs to be charged once and still has enough juice at the end of the day to watch a movie on the couch.

The Convertible function provides mobility in practically all situations and enables operation even when conventional notebooks have long since ceased to be able to keep up.

Switch between laptop and tablet mode via the Windows 10 notification bar. The system automatically asks whether to switch to tablet mode if the screen is rotated by 180 degrees.

Tent and Stand mode cannot be selected from the menu. Instead, simply set up the laptop as a tent or fold the keyboard back and you can continue working in the respective mode. The screen will automatically rotate accordingly.

Weighing in at 3.08 lbs, it’s neither too light nor too heavy, so you can easily take it with you wherever you go. Thanks to its smaller size, it will fit in most backpacks and handbags and can even be stored in the glove compartment.

Verdict

The advertising promise of the Lenovo Yoga C740, which we mention at the very beginning of the test, is definitely kept: The convertible is definitely suitable for creative people and those who don’t want to choose between a tablet and a laptop.

As the display can be turned in any direction, it’s also excellent for reading e-books. In general, it can be used in many comfortable positions. Clearly unsuitable for gamers, the laptop doesn’t even manage tempo on the lowest settings. But that’s also not the focus of the device.

Overall, we can draw a very positive conclusion. The CPU and the built-in M.2 SSD memory provide good performance for most work.

The Convertible is perfectly suited for everyday use with its strong battery, light weight, compact size and various modes. Picture and sound quality are outstanding for a device in the price range of around $700.

Users will have to accept a reduction in the visibility on the screen if they like to work outside in good weather or on the road. Even the tablet mode can’t completely convince us with regular jerking.

The occasional whistling noises of the fan and the not particularly lavish RAM provide for further deductions in the final grad, which is why the Lenovo Yoga C740 is ranking second versus the Lenovo Yoga C940.

The Lenovo C740 is way cheaper though, so if you search for a cheaper Office / Home Laptop, the Yoga C740 performs still good for its’ price class.
