Lenovo is simply the king of convertible laptops. They have arguably the best looking and the most versatile 2-in-1 range in the face of Yoga. One of the more-premium oriented Yogas is the Yoga C740.

We were able to get our hands on a 14″ version of the laptop, which (wait for it) is the first laptop in our office to feature the latest 10th Generation of Intel’s ULV processors.

As we were eager to test the new processor, we had to stay focused and not miss any issues. After all, we are talking about a convertible that is likely going to use for work, as it comes with a free stylus inside the box.

What’s in the box?

Apart from the obvious 65Wh power brick and the paper manuals, we found a Lenovo Pen inside the box, which is pretty exceptional from Lenovo. Of course, the Pen is optional and you might or might not receive it, depending on your region.

Design and construction

So, the Lenovo Yoga C740 (14) is an all-metal convertible laptop that has a pretty thin and lightweight body. It stops the scales at 1.40 kg and has a height of 14.9 mm in its thinnest point and 16.9 mm at its thickest. We have to say that the dark-grey matte finish manages to give the laptop a premium look, although it is somewhat of a fingerprint magnet. Aside from this color, the Yoga C740 (14) comes in a silver outfit, as well.

Quite expectedly from a 2-in-1, we weren’t able to open the lid of the laptop with a single hand. However, we were certainly impressed by the strength of the lid itself – this thing barely moves when you try to bend it around itself. The strength of this laptop is likely boosted by the use of metal on the back and glass on the front of the display.

Next, we have the base of the device, which is also very strong. Unlike some of its competitors, things are pretty busy around here. There is a rather comfortable keyboard, with a slightly shallow key travel to our likings, but yet very tactile feedback. We are also fans of the speakers that are surrounding the keyboard in a pretty Apple-esque fashion.

Then, there is a matte glass on top of the touchpad, which feels agile and snappy. Last, but not last place, you can find a fingerprint reader just beneath the “Right” arrow key.

Since the speakers are at the base of the laptop, and the hot air is getting out of the laptop from its back, the only thing you can see on the bottom plate is the single ventilation grill.

Ports

Lenovo shouldn’t be very proud of the I/O selection on this laptop. It has two USB Type-C 3.1 (Gen. 1) ports on the left (both can be used for charging), as well as a headphone jack, while the right side houses only one USB Type-A 3.1 (Gen. 1) port and the power button.

Disassembly, upgrade options and maintenance

The Yoga C730 (14) has 9 Torx-headed screws that hold the bottom panel to the chassis of the device. After you remove them, make sure you are very careful with your plastic pry tool, because the package is pretty tight.

Despite the usage of a pretty standard cooling setup, it is interesting to see how short and fat the heat pipe in use actually is. Moreover, around 50% or more of its length is concentrated in making contact with the heat spreader.

Sadly, you won’t be able to upgrade Yoga C740 (14)’s memory, as all of the chips are soldered. Ultimately, this means you are left with the maximum amount of RAM being 16GB. At least Lenovo didn’t solder the SSD chips but is rather using an M.2 PCIe x4 slot to your favor.

Battery-wise, there is a 51Wh pack, which takes a good amount of the bottom half of this device.

Battery

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. Lenovo has put a 51Wh battery pack inside of this machine.

While Lenovo is stating this laptop would be able to reach 13 hours of battery life. However, surprisingly, we were able to get even more out of it – more than 15 hours of Web browsing and 14 hours and a half of video playback.

CPU options

Lenovo Yoga C740 features the latest 10th Gen. processors from Intel. You can buy the laptop with the Core i5-10210U or the Core i7-10510U, which are four-core/eigh-thread CPUs, and there is the Core i7-10710U, which has six-cores and twelve-threads.


GPU options

All of the aforementioned processors come with the update Intel UHD Graphics, which this time doesn’t feature a number, whatsoever).

Temperatures and comfort

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Intel Core i5-10210U (15W TDP) 0:02 – 0:10 sec 0:15 – 0:30 sec 10:00 – 15:00 min

One of the biggest challenges in a thermal standpoint for this laptop is the amount of airflow feeding to its cooling. As the laptop is super thin and its feet are similar to the ones on a hobbit, you can expect, that it has vacuumed itself to the desk, when you stress test it. This is one of the main reasons for the high temperatures at the beginning of the torture and the sub 2.00 GHz frequencies at its end.

Comfort during full load

Verdict

First, let’s start by noting that our artistic talents (or the lack of them) prevented us from showing our most creative users deep information about this product. However, we were able to get a thing or two for them. One of the major positives of this laptop’s Pen usage is its accuracy. We found it to be more accurate than the Yoga 730 for example. The Yoga C740 (14) also has better palm rejection, while the biggest issue we had was when the screen was handled with oily hands. After that, the stylus seems to slide or skip a pixel, mainly because of the unevenness of the surface. So make sure you clean it well with screen spray and a cloth towel before you go on your drawing endeavors.

Then there is the exceptional battery life, that surpasses even Lenovo’s claims. The Yoga C740 (14) managed to go through 15 hours of Web browsing solely on battery power. At the same time, if you are onto a movie marathon, the laptop is going to last around 14 hours and a half.

Apart from the display, the other two input devices are pretty comfortable in the long run. While the keyboard has a pretty short key travel, and you will definitely need some time getting used to that “Enter” key and the proximity of the slash sign, its feedback is decent and the keycaps are pretty sizeable. Moreover, it has a backlight, while the touchpad has a matte glass cover for better gliding.

Additionally, there are two pretty well sounding speakers, surrounding the keyboard. While they produce loud and dynamic audio, there is a noticeable lack of punch.

Sadly, you won’t be able to upgrade the RAM on this one, as there are no RAM DIMMs available anywhere on the motherboard. On the bright side, you can upgrade the storage via the solo M.2 port, which fits PCIe x4 NVMe drives as well. We can add to that the lack of Thunderbolt connectivity, and the overall limited I/O selection.

Lastly, we have to mention the Core i5-10210U processor, this laptop was equipped with. Once more, Intel didn’t disappoint in terms of efficiency, however, we didn’t see any major improvement over the Core i5-8265U. Or at least with this laptop.

Pros

  • Good all-metal build
  • Great battery life
  • A Pen included inside the box
  • Responsive touchscreen with little to no lag
  • Supports PCIe x4 SSDs

Cons

  • Modest I/O sellection
  • No RAM upgrade is possible
  • Lacks Thunderbolt connection
