The contact activated dual-display Yoga E book C930  is a “one a sort” computing machine that can’t be categorized underneath any current market phase since it’s neither a laptop computer nor a pill and can’t be considered solely as a note-taking product or a 2-in-1 pill. That’s the reason, not like our typical evaluations, it’s tough to match it to any cell computing product presently out there.

The successor of the primary Yoga E book launched in This fall 2016, the Yoga E book C930 shares a few of its key options whereas delivering rather more efficiency and a whole lot of enhancements, for the next price ticket: $949.99 MSRP for the bottom model (128GB), and $1049.99 for the 256GB mannequin. The 2016 model was very reasonably priced: Android $499 for the Android mannequin (64GB)  and $549 for the Home windows one which lacked first rate efficiency.

Equally to the unique Yoga E book, the secondary show homes the digital keyboard, nevertheless, it’s an E Ink contact show, and never a printed capacitive contact floor, that can change from keyboard-mode to handwriting and drawing-mode with out the necessity to add paper on prime of the contact panel.

Moreover the E Ink show supporting the Energetic Pen (Wacom AES assist), probably the most noticeable adjustments from the earlier mannequin are the working system and the SoC, Lenovo favored Home windows 10 over Android for the Yoga E book C930 and upgraded the processor from an Intel atom x5-Z8550 to an Intel Core i5-7Y54 (See our specs comparability web page).

We had been very joyful about this important system improve, realizing that the majority pc pill customers require a full model of Home windows for the productiveness functions, with first rate efficiency to work whereas on-the-go.

What’s new? Yoga E book C930 vs. the unique Yoga E book

Programmable keyboard (from customers suggestions): the unique Yoga E book had a static “Halo” keyboard which was “printed” and couldn’t be modified. The keyless keyboard is the first purpose why the pc was so skinny, so it needed to keep, however now, it’s housed by an E Ink touchscreen HD show. The typing expertise is a lot better than with the Yoga E book.Bigger touchscreen with increased decision, the  major show is now 10.eight” and QHD (2560 x 1600)- it was 10.1” FHD within the earlier mannequin > the bigger kind issue permits having a bigger keyboard and extra comfy typing expertise within the secondary E Ink displayNow you’ll be able to take notes on each shows with out the necessity of a paper notepad: on the new E Ink show and the colour LCD show – a much-requested function by early adoptersKnock twice on the display screen or lengthy press the amount down button to open barely, it’s handy for one-hand operationLenovo added an infrared fingerprint sensor on the prime proper nook of the E Ink panelNow the Lenovo Energetic Pen options 4096 strain ranges, helps Wacom AES expertise and is included with some modelsImpactful improve: Core i5-Y754 (four.5W TDP)! From an Intel Atom X5 processor within the authentic  2016 versionNo extra 8MP major digicam – Lenovo saved the two MP HD webcam for video callsRemoved Micro HDMI, micro USB, and three.5mm audio jack ports to switch with two USB-C ports (Three.1-gen1, each with charging functionality.A hair thicker at 9.9mm (vs. 9.6mm) and heavier 775g (vs. 690g) than the earlier model for a lot better efficiency.

Industrial Design (Wonderful)

From the surface, the Yoga E book C930 appears to be like like its predecessor, with the same skinny and light-weight physique manufactured from magnesium alloy and aluminum, and nonetheless options the well-known slim and durable “watchband” hinge with a distinct coloration. Lenovo opted for a extra delicate darkish gray with a number of silver highlights, to switch the shiny silver and gold hinge.

The within is completely completely different, primarily with the substitute of the capacitive floor housing the printed “halo keyboard” by a 10.eight” FHD (1920 x 1080) Versatile E Ink Mobius touchscreen with Wacom-enabled Energetic Pen assist.

Weighing solely 775g, the 10.eight″ 2-in-1 pill is just 9.9 mm when closed and four mm at it slimmest edge when open. The brand new secondary E Ink touchscreen and the extra highly effective hardware configuration explains the 85g weight achieve and the slight thickness enhance (solely four mm).

In line with Lenovo, the 2016 Three-axis “watchband” hinge was manufactured from 130 completely different mechanical items and 5 completely different supplies to permit laptops to be very skinny and to swivel at 360 levels. And it delivers on the guarantees: at 9.9 mm (zero.39”), the Yoga E book C930 is solely 1.four mm (zero.06”) thicker than the Floor Professional 6 with out its Kind Cowl (removable keyboard housed within the cowl).

With the Yoga E book C930, Lenovo delivers a powerful construct high quality in an ultra-thin and swiveling clamshell kind issue, a primary in that class.


Double-knock or long-press quantity all the way down to open with one hand

Maybe to take care of the design language slim and clear, Lenovo renounced so as to add a small cutout to open with one hand, and as a substitute permits customers to double knock on the quilt or lengthy press the amount down button to take action. Some individuals might not like this revolutionary function as a result of they like to stay to their habits, for my part, the double knock could also be a very good different to open a clamshell laptop computer when you get used to it.

Infrared fingerprint scanner

Since Lenovo opted for a Home windows 10 model, the addition of an infrared fingerprint scanner was an apparent alternative in case some companies requiring safety options would choose that machine. I’m enthusiastic about structure or design companies, for instance. Infrared fingerprint sensors could be extra forgiving to greasy fingers.


The selection of ports was a subject of complaints with the earlier mannequin, and Lenovo appears to have listened to the consumer suggestions. The only micro USB and micro HDMI ports have been changed by two USB-C Three.1 ports, each charging, which is a greater configuration. Some individuals would remorse the removing of the audio jack, nevertheless, the pattern is gaining extra traction like in the newest smartphones. The quantity rocker and the ability button are situated on the proper aspect of the E Ink panel. From our day by day utilization, we all know it could be extra handy to have them positioned on the proper aspect of the IPS show.

The microSD slot is situated on the left aspect of the E Ink show, near the hinge and to the opposite the USB-C Three.1 charging port.

E Ink Show with Keyboard, Handwriting, and E-reader

What units the Yoga E book C930 aside from any 2-in1 pill pc is its secondary 10.eight FHD touchscreen E Ink show that includes three modes: digital keyboard, digital notepad/sketchpad, and e-reader. You turn from one mode to the opposite by tapping the icons on the prime proper nook of the monochrome secondary show, and from there you’ll be able to entry the E Ink panel settings.

Digital keyboard and Typing Expertise – higher than the unique Yoga E book

The digital keyboard on the E Ink FHD touchscreen show in Traditional Mode

The Yoga E book C930 just isn’t designed for individuals who must carry out lengthy writing periods like writers or journalists. It’s best fitted to burst typing, for individuals who principally like to make use of an ultra-compact laptop computer on-the-go, writing emails, shopping the online, consuming visible content material and taking notes or sketching. The keyboard learns your habits to enhance the expertise over time. I’ve not used it for lengthy sufficient to verify the declare. Please notice that E Ink expertise can’t be backlit.

Sound and haptic suggestions for the keyless keyboard

The keyless keyboard gives various kinds of suggestions to switch the bodily sensation of the important thing journey with sound or haptic suggestions. The latter slows down the responsiveness whereas the sound is adequate to make the expertise comfy.

Traditional and Fashionable keyboard modes in black or white variations

The Traditional mode delivers the simplest expertise because it shows the touchpad in any respect time whereas the Fashionable format gives bigger keys however disguise the trackpad by default, and make it seem instead of the house bar when taping the realm beneath it, which makes the utilization tougher.

Typing expertise and trackpad – wonderful for brief typing periods

To be honest, I’m not an professional typist, and I do know this keyboard could also be irritating for fast-typers. As an example, I began to jot down this overview on the Yoga E book C930, however actually, my productiveness was a lot better on my massive 30″ show and my common keyboard.
The trackpad is just a little difficult to make use of at first, as a result of absence of bodily click on, nevertheless, when in Traditional mode, it’s straightforward to get used to the left and proper “(silent) click on,” and choose sentences for copy/paste. The LCD touchscreen will also be used for a lot of actions, comparable to closing/shifting home windows, proper clicks, and so forth. That reduces the necessity for utilizing the trackpad.
As a designer, I are typically much more comfy with a mouse than a trackpad, particularly after I edit images and graphics in Photoshop, and I at all times carry a USB wi-fi mini mouse for my laptop computer when on-the-go.  I attempted it with the Yoga E book C930, and it labored nicely.

Handwriting and Sketching with the Lenovo Energetic Pen

Lenovo Energetic Pen – pairable with Bluetooth for buttons customization and presentation mode

The Wacom-enabled and AAA battery powered Lenovo Energetic Pen comes with some fashions of the Yoga E book C930 (be certain that to verify it earlier than shopping for). Out of the field, the pen begins to work instantly with the E Ink panel and Home windows Ink, or with One Be aware and Photoshop in case you have put in these functions.
The Pen’s three buttons are customizable provided that you pair the pen with the pc over Bluetooth. One neat possibility is the flexibility to set the pen to take screenshots by double-clicking the highest button.

Taking Notes: superb expertise with excessive responsiveness on each shows

Taking notes with the Yoga E book C930 will be achieved on the E Ink panel or immediately on the LCD touchscreen in numerous functions, comparable to One Be aware or Home windows Ink apps (or any suitable functions out there for Home windows). The responsiveness could be very quick on each shows, and the expertise is superfluid.

Convert handwritten notes captured in E Ink into textual content: could possibly be extra easy

The Yoga E book C930 is a computing machine particularly designed for individuals like me who don’t like typing and would somewhat take handwritten notes with a paper-like expertise that will convert to textual content simply. On the E Ink panel, the handwriting conversion to textual content is sort of sophisticated and never very clearly defined neither within the assist part nor within the consumer guides that you will discover on Lenovo’s web site. Fret not, I’ll clarify the way to do it:

Tips on how to convert Handwriting Ink to Textual content with the Yoga E book C930

1/ you write a sentence with the pen2/ you choose the sentence after clicking the lasso icon within the menu bar3/ then you definitely lengthy press on the double-rectangle icon within the menu bar on the prime till a drop-down menu appears4/ click on on the sub-menu “Copy as Textual content” (image-to-text conversion occurs now)5/ Open any utility from the primary RGB show comparable to phrase or powerpoint6/ Choose the previous operate in that utility, then your sentence is pasted as textual content there.I’m not certain if there’s a solution to convert a number of pages of notes into textual content without delay. Anyhow, I hope that the Lenovo software program workforce will launch an replace of the E Ink panel utility to permit for direct handwriting to textual content conversion of a number of notes. Researching this machine

Sketching: nice expertise on each shows

The Lenovo Energetic Pen permits nice management over the stroke width variations in line with strain and angle, due to the four.096 ranges of strain, the prime normal in immediately’s stylus expertise. It feels virtually like sketching on paper, the very best expertise for me was with the medium-size pen. If it’s worthwhile to carry out an extended note-taking session, the E Ink expertise is much more energy environment friendly. Making an attempt it with Photoshop (skilled model) was an incredible expertise as nicely, even engaged on a big file, the system was extremely responsive. As an example, I really like the drawing and note-taking expertise supplied by the 6.four” Samsung Galaxy Be aware 9 and its S-Pen, nevertheless, sketching on a bigger 10.eight” show is rather more comfy and produces extra satisfying outcomes.

E-reader doesn’t assist widespread e-book codecs, solely PDF

Sadly, the E-reader mode doesn’t assist widespread e-book codecs Mobi, and EPUB codecs didn’t work), and works solely with PDF information, which is sort of shocking for a contemporary E-reader.

Studying on an E Ink show could also be higher for the well being, it’s straightforward to transform ebooks to PDF

On the brilliant aspect, it’s now very straightforward to transform Kindle ebooks into PDF information, and with the Yoga E book C930, you are able to do all the things out of your mattress on one machine. Granted that your e-book file is already in your pc, convert it to PDF within the browser, and comfortably learn it on the built-in E Ink reader, which is now advisable by well being professionals to keep away from the publicity to blue gentle from common shows (TVs, telephones computer systems), as a result of it would intrude along with your sleep.
Lenovo is anticipated to assist the ePub and Mobi e-book format subsequent yr (to be confirmed).

The consumer interface could possibly be higher as nicely, it’s not that straightforward to regulate the zooming, and total, in addition to studying, the consumer expertise is much less agreeable than what you get within the Kindle.
I hope that Lenovo will work on the E-reader app and supply a greater software program with an replace subsequent yr.


Excessive decision and pixel density, good distinction with deep black
The bigger 10.eight” QHD IPS LCD tactile show delivers deep black ranges and vivid colours. The shiny end makes it reflective however enhances the colour saturation. Lenovo pumped up the decision from the final mannequin, and the elevated pixel density (280 PPi vs. 224) is sweet to have and better than the one discovered within the Floor Professional 6 (12.Three” at 2736×1824 > 267 PPI).

Premium brightness stage
The unique boasted a excessive brightness at 400 NITs (in line with Lenovo), and the brand new Yoga E book C 930 delivers 375 NITs as measured in our lab.

That stage of brightness is superb for a laptop computer, 350 NITs and above is a spread for premium units just like the Dell XPS 13 or the Floor Professional 6, with few of them reaching 500 NITS and above – assume MacBook Professional, LG V40, Huawei P20 Professional and Mate 20 Professional smartphones.

First rate coloration gamut
The show has an 85% sRGB coloration gamut in line with the technical specs, and it positively appears to be like prefer it. It’s barely beneath the common for this value and won’t be perfect for Artistic functions that require a really correct coloration copy. For sketching or informal video enhancing, it ought to be wonderful, and it’s no downside for informal gaming.


Lenovo saved the 2MP HD webcam for video conferencing on the prime of the Quad-HD IPS show and removed the 8MP major digicam beforehand positioned on the keyboard panel.


The aspect mounted audio system ship an incredible sound high quality with a surprisingly good quantity and sound high quality for such an ultra-thin chassis.  The machine options Dolby Atmos assist.

Software program

Lenovo favored Home windows over Android for this distinctive compact computing machine, and with this new mannequin, you get Home windows 10 Dwelling, which is Home windows full model for customers. As described within the keyboard and handwriting paragraph earlier, the E Ink show options proprietary software program that enables to modify from a digital keyboard to a note-taking and sketching utility and at last an e-reader.

System Efficiency

A laptop computer processor inside a tiny dual-screen fanless and swiveling kind issue!
Managing to combine an Intel seventh era Core i5-7Y54 (four.5W TDP) in a fanless ultra-thin and ultra-light dual-screen clamshell design with a keyboard is totally tough. The identical processor powers the bigger and far heavier 12.Three” Pixel E book 2017, so, Lenovo most likely confronted excessive challenges to package deal it on this tiny foldable pc.

From the benchmarks we suspect that Lenovo needed to throttle the efficiency to make the thermals work, the consequence is the Pixel E book 2017 is barely sooner with the identical SoC.

The closest machine we are able to examine to this dual-display tiny swiveling computing machine is the 12.Three” Microsoft Floor Professional 6, which incorporates a bigger kind issue and is thicker (10.7 mm) whenever you embody its Kind Cowl that homes the keyboard.

Many individuals commented on the higher efficiency delivered by the Microsoft machine, due to its the eighth era Intel Core i5-8250U or i7-8650U (15W TDP). We all know that it’s simpler to accommodate a robust processor in a bigger and thicker chassis that isn’t cut up in half, particularly to accommodate the thermals.

An awesome efficiency improve in comparison with the unique Yoga E book

Lenovo got here up with two variations of its authentic Yoga E book, one that includes Android and the different working on Home windows. Nonetheless, the Intel Atom x5-Z8550 was not highly effective sufficient to make the Home windows expertise sufficiently quick for many customers, so we reviewed the Android mannequin.

Within the Geekbench four chart beneath you’ll be able to see how a lot efficiency achieve the brand new CPU (in inexperienced) delivers in comparison with the predecessor (in purple). (processor benchmark)

When in comparison with different 13” and 14” clamshell laptops that includes extra muscular processors such because the Dell XPS 13 (9370), you’ll be able to see on the PC Mark eight Dwelling that the brand new Yoga E book C930’s efficiency is nearer to a bigger laptop computer efficiency than the earlier Yoga E book.

Perceived efficiency: very highly effective for the scale

We examined the system with compute-hungry functions, comparable to picture enhancing and drawing utilizing Photoshop with a number of information open (one was high-resolution 24MP 6000×4000) whereas a number of tabs had been open within the browser in addition to on Phrase file. The Yoga E book C930 might handle nicely, though it was just a little slower than a prime laptop computer configuration just for opening the information. The efficiency was nice for picture enhancing and drawing. We suggest to carry out note-taking periods on the E Ink show with out Photoshop working.

Please notice that I examined the system with Photoshop (skilled model) as a result of some individuals would most likely like to attract utilizing Photoshop’s incredible instruments. Nonetheless, this machine just isn’t focused as a main pc for imaging professionals (i.e., photographers, videographers). It’s not appropriate for lengthy and complicated periods of picture enhancing on lots of of photos concurrently. The Yoga E book C930 is okay for enhancing smaller batches of high-resolution images.



With a battery capability of 36WH and a battery life estimated at eight hours with Mobilemark 2014 by Lenovo, on the paper, the Yoga E book C930 is on par with our expertise engaged on numerous Home windows laptops. In actual life, battery depletion velocity is so extremely reliable on which workload and kind of duties you carry out that it’s almost not possible to estimate any “common” length.

We measured the battery utilization underneath numerous workloads, so these examples could be good indicators to estimate what it could appear to be for various customers.

Intense workload with WiFi on  – 6 to 7 hours of battery life

1/ Utilizing Photoshop for drawing, Phrase open, Web browser open over wifi, multitasking forwards and backwards on each shows, measured throughout one hour: the battery dropped by 14%

Which signifies that the Yoga E book C930 would final for 7 hours and 14 minutes on a single cost. (If we think about the battery depletion as linear underneath the same workload)

2/ Downloaded Chrome and Firefox and typed textual content on a Google doc, a number of tabs open, WiFi on, measured throughout 51 minutes: the battery dropped by 13 %
Beneath a linear battery depletion price with the same workload, the battery would final for six hours and four minutes.

In our expertise multitasking on Home windows laptops powered by Intel processors (with WiFi on), we by no means obtained greater than 5 to six hours of battery life, which is analogous to what the reviewers at Home windows Central discovered for the Floor Professional 6 utilizing the PC mark eight check.

Extremely minimal workload with WiFi on – 19 hours 33 minutes of battery life

When measured for 4 hours and thirty minutes with some web shopping, sketching for a restricted period of time on Photoshop and taking notes forwards and backwards on each shows with WiFi on, and on sleep mode in between quick work periods, the battery dropped by 23%.
Beneath a linear battery depletion price with the same workload, the battery would final for 19 hours and 33 minutes.
We didn’t strive multitasking with solely the E Ink show on and no WiFi for an hour, so we have no idea how the battery would carry out underneath that specific workload.

Deep sleep with WiFi on – Three% battery drop in 18 hours

When on deep sleep with WiFi turned on throughout 18 hours (routinely related earlier than and after going into deep sleep), the battery dropped by Three%.

Gradual Charging – 2 hours to cost in full

The charging time is sort of disappointing, at zero.Three Wh per minute (18Wh/hour) it takes about two hours to totally cost the Yoga E book C930. That is beneath common efficiency and means slower what Lenovo normally delivers for its Home windows laptops. For instance, the ThinkPad T480 prices at zero.9 Wh per minute (54 Wh/hour) and is totally charged in about one hour.


The Lenovo Yoga E book C930 is an extraordinarily revolutionary laptop computer constructed with two distinct options:

1/ an extraordinarily gentle and small clamshell design
2/ a distinctive E Ink secondary show.

These can be the explanation why customers are considering a purchase order.

E Ink offers a novel visible expertise that LCD or OLED show can’t mimic. Many individuals simply love that feeling, and they won’t need to carry a dumb e-book machine for that. In a footprint that’s corresponding to an E Ink e-book (just like the $550 Onyx E book), you will get a full-blown Home windows pc which is surprisingly highly effective for its measurement.


The clamshell chassis stands in stark distinction with the legions of tablet-like units that get solely thicker and heavier after you add the keyboard. Clamshells additionally give customers rather more management over the orientation of the show.

As with all product not designed for the plenty, there are trade-offs comparable to comparatively excessive value, typing velocity, computing energy, variety of ports, and so forth.,
Ultimately, this laptop computer is focused for a distinct segment market, and it looks like you will have achieved your homework. Thanks for studying!

Total product score: 7.5/10
