Let’s not forget one thing in the world of laptops: Lenovo has been more innovative than you might think. The manufacturer has after all been at the forefront of the fashion for convertible computers with its Yoga range. Also, we always expect a lot from its latest devices. With the Yoga Slim 7i Carbon, Lenovo was almost flawless… Almost.

Lenovo Yoga Slim 7i Carbon (13IAP7)Design

The design of the Lenovo Yoga Slim 7i Carbon is interesting for several things. Firstly for its orientation: the way the logos are oriented, it makes you want to be held vertically like a sort of book. And it works: with its amazingly textured magnesium-alloy shell, perhaps related to those built-in “Web-Core 2.0 multi-layer carbon fibers” that Lenovo talks about, it has that little premium je-ne-sais-quoi. which takes effect.

This is in addition to its ultra rounded edges, which combined with its featherweight 995 grams gives the impression of using a tablet more than a laptop. It becomes almost shocking that the latter is not a transformable format, as everything seems optimized for it. Really, the Lenovo Yoga Slim 7i Carbon is an attractive computer in many ways.

Keyboard and touchpad

Alas, the romance will end here. On this very specific point: that of the keyboard. Everything was fine on paper though, with fairly large keys and a full-size Enter key. Its keys have very little travel, but that’s no big deal on such a thin computer.

But here it is… The Space key is unbearable. Almost unusable. This one has even less stroke than all the others, and is not equal. It works pretty well if you press left, yes. If you press in the center of it, you have an 8 out of 10 chance that your press will not be recognized. And if you press on the right of the device, you have a 3 out of 10 chance that your press will be recognized twice. Two spaces in your text, therefore. The problem is such that I had to abandon the idea of ​​typing this test on the computer itself, as is our tradition, to return to my usual Chromebook.

It’s a real disappointment, since everything else is good. The touchpad is excellent and slides under the finger. The format, the width… Anything goes. If only that Space key wasn’t so bad.

connectors

On the left, you will find a USB C Thunderbolt 4 port. On the left, a “simple” USB-C 3.2 Gen 2 port compatible DisplayPort 1.4, power supply and with a bandwidth of 20 Gbit / s. You will also find a physical switch to disconnect the webcam, to protect your privacy.

It is obviously a light configuration, which goes with the concept of the computer. Again, it reminds a tablet more than a PC, but everything remains consistent. What’s more, a Thunderbolt 4 port naturally unlocks many possibilities with its 40 Gbps bandwidth.

webcam and audio

The webcam, which is also Windows Hello compatible, is in an interesting location again. The cover of Lenovo Yoga Slim 7i Carbon has a small protrusion not only to open it easily, but also to accommodate its sensors. A very good idea, even if the webcam itself is only 720p. She doesn’t work miracles.

The same goes for the speakers, which are located below the machine. Not the most optimized placement around, but again forgivable. The volume is surprisingly powerful, with well-defined highs. The mediums are not set back, but lack a bit of body. As for the basses… They are non-existent, of course. It’s not all bad.

Lenovo Yoga Slim 7i Carbon (13IAP7)Screen

The Lenovo Yoga Slim 7i Carbon is equipped with a 13.3-inch 8-bit IPS LCD panel in 2560 x 1600 pixel definition at a 16:10 ratio. This is compatible with a refresh rate of 90 Hz, although it is configured by default at 60 Hz. It is also tactile, again a missed opportunity to make it a transformable device.

Under our probe and with the DisplayCal software, we notice that as promised by the manufacturer, the panel covers 99.9% of the sRGB space. It is even perfectly calibrated for this. This is not the case with Adobe RGB, covered at 68.8%, or DCI P3 at 70.7%. The average color temperature is raised to 6400K very close to the 6500K of the video standard, and the contrast ratio is very good at 1281:1. The average Delta E00 compared to the DCI P3 space is at 2.35, which is very good.

It is perhaps its maximum brightness, raised to 361 cd / m², which is a bit disappointing. Admittedly, this is enough for the computer to be readable in direct sunlight, but not as comfortably as with a good 500 cd/m². You can also forget about HDR. But all in all, the Lenovo Yoga Slim 7i Carbon is excellent for anyone working in the sRGB space, which is primarily the web. It’s not the perfect computer for video editors, but it never intended to be.

Lenovo Yoga Slim 7i Carbon (13IAP7)Software

Lenovo generally remains discreet in its software retouching. That’s still the case here on the Yoga Slim 7i Carbon, which really only has the basic McAfee setup as a bad trait. It’s still adware, whether we like it or not.

Conversely, Lenovo Vantage is still one of the best interfaces to manage device settings finely. It represents the best central point between the good nerd who absolutely wants to fine-tune everything, and the neophyte who must still understand what he is doing.

Lenovo Yoga Slim 7i Carbon (13IAP7)Performance

In our test configuration, the Lenovo Yoga Slim 7i Carbon is equipped with the Intel Core i7-1260P, a SoC with 12 cores including 4 performance and 8 efficient for 16 threads, which can turbo up to 4.7 GHz. It’s backed by 16GB of LPDDR5 RAM, and 1TB of PCIe Gen 4 storage.

General benchmarks

In performance mode, the Lenovo Yoga Slim 7i Carbon behaves exactly as expected with its i7-1260P chip. We find on Cinebench R23 substantially the same results on the LG Gram 17, the Samsung Galaxy Book 2 Pro or the latest Zenbook 14, with 8942 points in multi core and 1503 points in single core. The same is true on PCMark 10, with a score of 5091 points.

Still the same result for the Samsung SSD in PCIe Gen 4. It should be noted that among the ultrabooks recently tested, the Yoga Slim 7i Carbon is the one that got the best scores despite its thinness.

Cooling and noise

And that, he pays a little bit on the heating side. Even using its normal mode, the computer quickly reaches 52°C at the bottom of the chassis. If you use the Yoga Slim 7i Carbon mainly on a desk or any flat surface, you won’t feel it. The other parts of the laptop remain comfortable. But if you use it on your lap… Ouch.

Lenovo Yoga Slim 7i Carbon (13IAP7)Autonomy

The Lenovo Yoga Slim 7i Carbon is equipped with a small 50Wh battery. It can be recharged using any of the computer’s USB-C ports, and any charger using the PowerDelivery standard.

In typical use, which is what this computer is intended for, with many open tabs, a few videos and a bit of music… The Lenovo Yoga Slim 7i Carbon will last between 9 and 10 hours. It is within the framework of the manufacturer’s promises once again, which did not lie on its technical sheet.

Nine hours of autonomy does not allow it to be on the podium of the latest ultrabooks, but it is still a very good performance. Especially for a laptop as thin and portable as this one.

Lenovo Yoga Slim 7i Carbon (13IAP7)Price and availability

The Lenovo Yoga Slim 7i Carbon is already available in France. The configuration of our test is sold at 1,799 euros, but you can find the PC in i5 configuration around 1,300 euros.
