Lenovo ThinkPad X390 Yoga review – security or versatility – why not both?

A ThinkPad that turns right into a tablet – what more would one want? That may be a very relevant query if it wasn’t for the $1200+ price ticket. With that stated, allow us to present you the Lenovo ThinkPad X390 Yoga, which is likely one of the costlier 13-inch convertibles available on the market but in addition aims to be one of the crucial versatile and durable ones.

Hardware-wise it packs the Whiskey Lake Intel ULVs and tops out with the vPro Intel Core i7-8665U. Moreover, you get a ThinkPad Pen Professional stylus that has its proprietary place inside the laptop computer’s chassis. Typically manufacturers embrace a dedicated stylus with the convertible laptops they sell, but it’s often discovered contained in the field… very not often contained in the pocket book, itself.

You’ll be able to verify the costs and configurations in our Specs System:

What’s within the box?

Inside the field you, aside from the laptop computer yourself you will find some paper manuals and 65Wh power brick, that based on Lenovo is able to charging your laptop from Zero-80% in simply an hour.

Design and development

ThinkPad X390 Yoga’s physique is made out of metallic and has a matte finish to it, vastly decreasing the variety of fingerprints on the fabric. In addition to that, the laptop computer is super mild at 1.29 kg (2.85 lbs) and has a profile of slightly below 16mm.

As a convertible, its lid is inconceivable to get opened with a single hand, nevertheless, it could go all the best way to the back of the gadget. Its touchscreen itself could be very correct and the palm rejection is on point. As we talked about the laptop computer comes with a ThinkPad Pen Professional that fees instantly from the slot that’s meant for it.

Onto the bottom of the system, you possibly can see the standard ThinkPad keyboard with U-shaped keys and the purple “nipple” in the middle. It has a slightly lengthy key journey and clicky feedback, which makes it super snug to sort on. On the touchpad aspect, we have been not 100% with the gadget. Although it’s pretty accurate we found it to be slightly irresponsive. Nevertheless, you continue to have the devoted buttons on prime which are greatest paired with the “nipple” itself.

Simply on the fitting of the touchpad, you will see the fingerprint reader. Props to Lenovo for installing a such, especially given the truth that it is blazingly fast – simply faucet it together with your finger and it will read it.

Lastly, there’s the bottom of the laptop computer, where you’ll see the ventilation grills as well as the speaker cut-outs, whereas scorching air comes out from the back of the system.


ThinkPad X390 Yoga is provided with a USB Sort-C charging plug, followed by a Thunderbolt Three connector and an Ethernet extension, USB Sort-A 3.1 (Gen. 1) with Sleep and Cost, a headphone jack and an optionally available Smartcard reader. On the best, you’ll see an HDMI connector, a USB Sort-A Three.1 (Gen. 1) port, a microSD card reader, the facility On/Off change (that’s fairly exhausting to differentiate on touch) and at the edge of the laptop computer is the place the stylus resides.

Show quality

Lenovo ThinkPad X390 Yoga has a Full HD touchscreen IPS panel, AUO B133HAN05.9. Its diagonal is 13.Three-inch (33.78 cm), and the resolution – 1920 х 1080p. Moreover, the display ratio is 16:9, the pixel density – 166 ppi, their pitch – 0.153 х Zero.153 mm. The display might be thought-about Retina when seen from at the very least 53 cm (from this distance, the typical human eye can’t see the individual pixels).

Viewing angles are wonderful on this gadget. We provide pictures at totally different angles to guage the quality.

The maximum measured brightness is 317 nits (cd/m2) in the midst of the display and 303 nits (cd/m2) average across the surface with a maximum deviation of 9%. The Correlated Colour Temperature on a white display and at most brightness is 6850Okay – barely colder than the 6500Okay temperature for sRGB. The typical colour temperature by way of the grey scale earlier than profiling is 7040Okay.
Within the illustration under you’ll be able to see how the show performs from uniformity perspective. The illustration under exhibits how issues are for operational brightness ranges (roughly 140 nits) – in this specific case at 72% Brightness (White degree = 143 cd/m2, Black degree = Zero.Zero86 cd/m2).
Values of dE2000 over 4.Zero ought to not occur, and this parameter is among the first it is best to examine when you intend to make use of the laptop for shade delicate work (a most tolerance of 2.0 ). The distinction ratio is superb – 1650:1 (1540:1 after profiling).

To ensure we are on the identical web page, we want to offer you just a little introduction of the sRGB shade gamut and the Adobe RGB. To start out, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the seen specter of colors by the human eye, supplying you with a better perception of the colour gamut coverage and the color accuracy.

Contained in the black triangle, you will notice the usual colour gamut (sRGB) that’s being used by hundreds of thousands of individuals in HDTV and on the internet. As for the Adobe RGB, that is utilized in skilled cameras, screens, and so forth for printing. Principally, colors contained in the black triangle are used by everybody and that is the important a part of the color quality and colour accuracy of a mainstream notebook.

Still, we’ve included different shade spaces just like the famous DCI-P3 normal used by film studios, in addition to the digital UHD Rec.2020 normal. Rec.2020, nevertheless, continues to be a factor of the longer term and it’s troublesome for at this time’s shows to cover that nicely. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colours that naturally occur around us daily.

The yellow dotted line exhibits Lenovo ThinkPad X390 Yoga’s shade gamut protection.

Its show covers 97% of the sRGB/ITU-R BT.709 (net/HDTV normal) in CIE1976, which is a prerequisite for a punchy image.

Our “Design and Gaming” profile delivers optimum shade temperature (6500Okay) at 140 cd/m2 luminance and sRGB gamma mode.

We examined the accuracy of the display with 24 commonly used colours like mild and dark human pores and skin, blue sky, green grass, orange, and so on. You’ll be able to take a look at the results at manufacturing unit condition and in addition, with the “Design and Gaming” profile.

Under you’ll be able to examine the scores of Lenovo ThinkPad X390 Yoga with the default settings (left), and with the “Gaming and Web design” profile (right).

The subsequent figure exhibits how nicely the display is able to reproduce really darkish elements of a picture, which is important when watching films or enjoying video games in low ambient mild.

The left aspect of the image represents the display with inventory settings, whereas the proper one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you can find the grayscale and on the vertical axis – the luminance of the display. On the two graphs under you possibly can easily examine for yourself how your display handles the darkest nuances but take into account that this also will depend on the settings of your current display, the calibration, the viewing angle, and the encompassing mild circumstances.

Response time (Gaming capabilities)

We check the response time of the pixels with the standard “black-to-white” and “white-to-black” technique from 10% to 90% and vice versa.

We recorded Fall Time + Rise Time = 25 ms.

Health impression – PWM / Blue Mild

PWM (Display flickering)

Pulse-width modulation (PWM) is a simple method to control monitor brightness. Once you lower the brightness, the sunshine depth of the backlight is not lowered, but as an alternative turned off and on by the electronics with a frequency indistinguishable to the human eye. In these mild impulses, the sunshine/no-light time ratio varies, whereas brightness stays unchanged, which is dangerous to your eyes. You possibly can learn extra about that in our devoted article on PWM.

Lenovo ThinkPad X390 Yoga doesn’t use PWM to adjust the brightness of its display at any degree. This makes it notably snug for extended durations of use in this facet.

Blue mild emissions

Installing our Well being-Guard profile not only eliminates PWM but in addition reduces the harmful Blue Mild emissions while protecting the colors of the display perceptually accurate. For those who’re not accustomed to the Blue mild, the TL;DR version is – emissions that negatively have an effect on your eyes, skin and your entire body. Yow will discover extra information about that in our dedicated article on Blue Mild.


Lenovo ThinkPad X390 Yoga has a touchscreen panel with a Full HD resolution, a very good distinction ratio, and cozy viewing angles. Furthermore, it has a large colour coverage (97% of sRGB) and its backlight doesn’t flicker. Although the colours are not very accurate, as quickly as you apply our Gaming and Net design profile, they get into Net design normal territory.

Purchase our profiles

Since our profiles are tailored for each individual display model, this article and its respective profile package deal are meant for Lenovo ThinkPad x390 Yoga configurations with 13.3″ AUO B133HAN05.9 (FHD, 1920 × 1080) IPS panel.

Workplace Work ought to be used principally by users who spend most of the time taking a look at pieces of text, tables or just surfing. This profile goals to deliver higher distinctness and clarity by holding a flat gamma curve (2.20), native colour temperature and perceptually correct colours.

Design and Gaming - screen profile

Design and Gaming

This profile is aimed toward designers who work with colours professionally, and for video games and films as properly. Design and Gaming takes display panels to their limits, making them as correct as potential in the sRGB IEC61966-2-1 normal for Net and HDTV, at white level D65.

Health-Guard - screen profile


THealth-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the unfavorable Blue Mild which impacts our eyes and physique. Because it’s custom tailor-made for every panel, it manages to maintain the colours perceptually correct. Well being-Guard simulates paper so the strain on the eyes is drastically decreased.



Lenovo ThinkPad X390 Yoga has a comparatively good high quality, quite loud sound, coming from its speakers. Its low and mid tones have deviations, whereas the highs are clear.


You possibly can obtain all the drivers and utilities you want on Lenovo’s help web page:


Now, we conduct the battery exams with Windows Higher efficiency setting turned on, display brightness adjusted to 120 nits and all other packages turned off apart from the one we are testing the notebook with. This laptop has a 50Wh battery pack.

It was enough for 10 hours of net shopping and around 11 hours of video playback, which is pretty good – it’s going to final a full work day only on battery power.

CPU options

As of the writing of this review, this laptop has a couple of processor choices. Aside from the quad-core Core i5-8265U and Core i7-8565U, Lenovo is offering the gadget with the vPro model of the latter – the Core i7-8665U.

GPU choices

Intel UHD Graphics 620 is a refresh of the HD Graphics 620 found as an integrated answer in many ULV Kaby Lake processors. UHD Graphics 620 is codenamed “Kaby Lake R U GT2” and it’s part of the Gen 9.5 era.

Intel UHD Graphics 620 has roughly the same efficiency as HD Graphics 620, relying on the other elements in the system. UHD Graphics 620’s efficiency is just like AMD Radeon R5 M420X and NVIDIA GeForce 910M/920M.

We are not going to hide our frustration with how scorching the CPU was operating in the course of the torture check. Nevertheless, we will forgive the ThinkPad X390 Yoga, since it’s a relatively skinny gadget and its cooling potential is tremendously lowered by that. Actually, the stress check began off great, with the laptop computer with the ability to obtain 2.97 GHz. Expectedly, within the minutes to comply with, the clock velocity dropped progressively and reached 1.71 GHz (nonetheless above the base frequency).

Consolation throughout full load

ThinkPad X390 Yoga will get pretty scorching on the surface. We measured a most temperature of 48C, because the hotspot was between the “R” and “T” keys. On the brilliant aspect, the palm-rest space was comparatively cool.


Regardless of whether you are looking at this gadget as a convertible or as a business answer, in both ways it will fulfill your needs completely. It is as reliable as a ThinkPad and as versatile as a Yoga. This seems like a sacred combination and it definitely feels as such – the laptop computer is loopy quick (even when paired with only a SATA SSD).

One of the crucial impressive features of the ThinkPad X390 Yoga is its keyboard – despite the thin profile of the laptop computer, Lenovo managed to place a keyboard with an honest quantity of travel and sustaining a clicky enough feel. Nevertheless, in distinction to the ThinkPad Yoga X1 Carbon, the keyboard doesn’t detract inside the chassis, if you turn the laptop computer in pill mode.

Efficiency-wise there’s nothing to complain about – the Core i5-8265U in our unit was utilized at a enough degree, although we observed a bit of larger than regular temperatures, both in and out. On the brilliant aspect, the environment friendly processor leads to relatively good battery life – 10 hours of net searching and somewhat bit extra when enjoying videos. Additionally, the 65W charging brick can charge the 50Wh battery pack from 0 to 80%.

As a half-laptop-half-tablet system, the ThinkPad X390 Yoga depends most dearly on its display. Being both an enter and an output peripheral, the display needs to be on a high degree. This is exactly what happens here as the AUO B133HAN05.9 panel is fairly shiny, has excellent distinction and covers 97% of sRGB. Its default shade settings are a bit inaccurate, though when our Gaming and Net design profile is applied, the color accuracy improves by a ton. More specifically, we see a drop within the common dE from 5.7 right down to Zero.8 (the standard for Net design is 2.Zero).

Finally, this is likely one of the greatest choices in case you are keen on gifting away some huge cash on your hardware – Sort-C charging and Thunderbolt connectivity are just a number of the options which may persuade you in shopping for this laptop computer. Nevertheless, for those who want something a little less harsh on your finances – the Lenovo Yoga 730 (13″) is a very good choice.
