New article: Overview of hybrid tablet Lenovo Yoga Book: offshoot of evolution


# Introduction

Chinese the Lenovo, perhaps, already noted in all classes of portable devices, and a series of Yoga has become one of the business cards manufacturer. A variety of models in this series already won various awards and, of course, love and recognition of consumers.

New Lenovo Yoga Book, shown to the public in September at IFA, is difficult to attribute to any particular class of devices. Language does not turn to call the hybrid tablet folding design, consisting of two parts. Laptop-transforer – this is not a novelty, because used “iron” for its performance close to the previous generation set of flagship smartphones, and full keyboard in the usual sense of the term in this thing is not


The laptop tablet, a tablet with integrated graphics tablet, a laptop with integrated graphics tablet – they do not call it, but less surprising Lenovo Yoga Book in the early hours and even days use does not become. For someone with time it will become a toy for others may well remain the main working tool for a long time. And to understand what it is, let’s evaluate the novelty from all possible “angles”.


The device has got us in a protective film, box and supplied. The only accessory that have appeared in our hands, turned out to be the stylus to draw.

the first thought when meeting with the Lenovo Yoga Book: «what it is thin and light!” But no comparison – the model belongs to a new class, and then she is still the one and only.

New made in the spirit of minimalism. There are three color versions – black is “Yoga» (Carbon Black), and that got us to the test, gray (Gunmetal Gray) and gold (Champagne Gold). If we describe the construction of this amazing device as briefly as possible, we get something like this: in Lenovo took two thin shell made of a metal alloy, in a single set the touch screen, closed the protective glass, and the other put all the basic stuffing, battery and touch panel backlit.

All of this put together with a special hinge in the entire width of the hull, which is an exclusive feature of most models of Yoga. The mechanism is quite complicated and consists of a very large number of metallic elements, beautifully interwoven with each other.

He not only it looks good, but also provides the ability to use the device in four possible configurations with rigid fixation of a selected angle: as a laptop, as a regular tablet, a tablet, set at a certain angle, and as a tablet with a screen to draw. The latter possibility is provided including at the expense of a special surface on which to place the touch keyboard with touchpad. But more detail about the input devices will be discussed in the next section.

saying subtlety and lightness – 9.6 mm when folded and 690 grams – could to achieve through the use of cost-effective filling and lack of keyboard. It is quite far from the parameters of today’s 10-inch tablet, but as Yoga Book – tablet is not exactly a classic, and it would be incorrect to draw parallels.

When folded, the two parts of the device are held one after the other with the help of built-in magnets. Housing matte, but still all the surface quickly covered with fingerprints and stains. And if the work items (touch screen and keyboard) do nothing, the external elements in a gray or gold color should be a little less actively collect dirt. As for the build quality, then there is no major complaints have arisen – the device does not creak, not crunches, gathered tightly, with no visible gaps and uniform painting of parts


The only thing that we can say – the uneven fit two-piece device. It seems that the screen cover in our specimen was slightly bent, that, in general, is not surprising in such a small thickness.

The top of the screen unit is located two microphones – for better noise reduction. Two built-in speakers have found a place on both sides of the working of the device. The maximum volume (without wheezing), and the sound quality we were pleasantly surprised.

Minimalism in all affected the number and type of installed ports. The main body of the device could be located a micro USB version 3.0 is used for charging and connecting peripherals, micro HDMI to output video to an external source and a combined 3.5-mm jack for headphones and a microphone.

Tray for microSD type memory card | SDHC | SDXC capacity up to 128 GB is between the two main ports. In the version with Android promises to support LTE and the corresponding ability to set nanoSIM.

All controls are located on the opposite side: power button with integrated LED and a volume rocker. Windows button to call up the “Start” menu at the Yoga Book absent, which is easily explained by a unified base unit for multiple operating systems.

The bottom flat surface there is nothing other than a few stickers. The novelty does not require forced cooling, and therefore no legs and drilled holes for the inflow of cold air we have not seen.

According to the labels it becomes obvious that in front of us is an engineering sample that is produced at the end of May 2016. The working title of news – stands Yeti-Windows. The brief information of the built-filling device.

Input Devices

At Lenovo Yoga Book is difficult to identify the main input device information. On the one hand, the new product is positioned as a hybrid tablet (especially if we are talking about a version with Android 6.0), that is the main interface between the device and the user must be a screen. On the other – an extra work surface, which is a mixture of touch backlit keyboard and a graphic tablet to draw, not disconnected


With the touch screen, you can not understand for a long time. There had long been clear: multitouch (up to 10 simultaneous key presses) and tempered safety glass with a glossy surface. No problem when using the – clearly and without error


Much more interesting things Halo keyboard with tactile feedback. If it is absolutely simplify, it is semi-matte touchpad with applied markings for keys and backlit. If the backlight is turned off, all this looks a solid black canvas. Most often, however, a dirty black cloth – zalyapyvaetsya this part instantly and scour is not very easy.

The distance between the touch panel is about 2.5 mm, the size of the main keys – 15 × 15 mm, as in most laptops. The layout is quite usual – do not have to get used to for a long time. All special device management functions – change the brightness, volume, and so on – the default trigger without pressing Fn modifier. For the tactile feedback device uses a vibration motor, not allowing to create a direct link fingers with each key individually. Not to speak about the possibility of quick printing (especially blind). Typing on Yoga Book – it is work that takes time, and sometimes nerves


The companies claim that in fact, typing on a review of the hero – not a difficult task, because as assistants act already become a classic self-learning system automatic error correction and substitution of words. But it seems that it does not apply to the version with Windows, or are they just work on it very bad.

The area of ​​the touchpad is quite small – 67 × 35 mm, plus two separate sitting areas as left and right mouse buttons. Tactile feedback when pressed is not being used. Tin this area recognizes two-finger scrolling – and nothing more. Call comfortable touchpad we can not – affects a small area. In addition, if a long time not to touch it, he can refuse to carry out any action – your cursor gets stuck in one position, and it is difficult to budge. During the test, this feature is not rarely has created a variety of problems. Therefore, we strongly recommend that along with Yoga Book to use Bluetooth-mouse – well, or use the touch screen


Pressing the special key touch-sensitive surface instantly turns into a graphics tablet, based on Wacom’s technology is based on electromagnetic resonance phenomenon. To quote the producer: “ pen tablet provides the necessary energy to operate using inductive resonance, so no wires, no batteries pen does not require” . The surface records the pressure to 2048 levels. Blue borders are marked with four sides gray “ticks”. Needless pen – the most simplified version, without any additional buttons. When using of Yoga Book pressure force is not fixed, and therefore click on the pen, in fact, tantamount to touch a finger.

The difference of the working surface of the Yoga Book this Wacom graphics tablets is the lack of support for finger control and multitouch. But, most likely, this is purely a software limitation, because at least two-finger scroll gesture in touchpad works without problems, and the surface of the recording pressing the touch keys when they are activated.

Have Yoga Book optional accessories (according to some sources they are in the standard sales package): Real Pen, Paper Refill and Ink Tip. In Russian translation: a real pen, special paper blocks and replaceable rods. Together, they allow you to draw on paper and at the same time receive a copy painted on the screen in a special program. To do this, the paper is fixed by means of an additional plastic element on the workspace Yoga Book and the magic begins, which can be see on many commercials on YouTube. Unfortunately, we did not have to experience it.

as a webcam viewing the hero uses a conventional 2-megapixel medium quality module with fixed focus. The second module is an 8 megapixel autofocus camera mounted in the top right corner of the work of the new items. At first it seems that the location is quite strange, but it is necessary to turn the screen 360 degrees – in the hands of the user is a normal tablet with a suitably positioned rear camera

The basis used quad (two dual-core block) CPU Intel Atom x5-Z8550, in its essence is a system-on-chip (of SoC) codenamed Cherry-Trail. CPU nominal frequency of 1.44 GHz, and a load mode TurboBoost per core, it can be increased to 2.4 GHz with a proper level of cooling.

of SoC made by 14-nm standards, its maximum TDP of only 2 watts and a temperature mode of 0-90 degrees. The minimum frequency at which the processor operates in a simple and economical installation mode – 480 MHz. The size of the cache memory of the second level – 2 MB


as the graphics solution performs integrated graphics Intel HD Graphics 400 without its own dedicated memory. It consumes resources total LPDDR3-memory, and the maximum frequency of GPU does not exceed 600 MHz. According to information found on the Internet the core contains 12 execution units, but, according to all three tools we used, their 16. Where is the truth and a lie – not so important. All concerned only with performance and with it, we will look at the relevant section.
