Where do I even start with the Lenovo Yoga Book? It’s hard to lớn describe a device that doesn’t adhere to lớn any conventions or standards. The device is powered by a low-power Hãng sản xuất Intel Atom chip, it’s slimmer và lighter than any máy tính xách tay, it comes with a stylus, has no usable ports, offers great battery life and a keyboard unlike any other.

Do these assorted features make for a great device, however? Let’s find out.

Build & Design: 8/10

The Lenovo Yoga Book can turn heads; I’ll give sầu it that. Its astonishingly slim size factor, unusual keyboard and touch surface và various tiệc ngọt tricks mean that you’ll spkết thúc a great giảm giá of time explaining khổng lồ strangers what it is & what it does.


For a “laptop” that’s this thin and light, the device feel surprisingly good khổng lồ hold. Lenovo claims that the Yoga Book is made of some Magnesium alloy, but it feels more like premium plastic. An ipad tablet definitely feels like metal, this doesn’t.

That said, it’s very sturdy & there’s no squeaking to lớn be heard anywhere. The hinge in particular is rather nice. It’s the same thiết kế that Lenovo uses on its premium Yoga 900 & it’s right at home on the Yoga Book as well.


At 690 gm, the Yoga Book is very light. It’s by no means a device that you can use one-handed for long-stretches, but toss it into lớn a bag và you’ll forget it’s there. The hinge is a little stiff và you can’t open the device with one finger, as you would a regular máy tính xách tay. I found that the best way to lớn open the device is lớn literally hold it like a book & open it.

Once open, you find a glass surface that doubles as a keyboard, touchpad and digital notepad. Above sầu this is the 10.1-inch IPS LED screen with some rather thiông xã bezels.

On the side is where our complaints start. The left side is host khổng lồ a single micro-USB port (for charging and data transfer) & a mini-HDXiaoMi MI port. Beside the two ports is the full bộ SIM card và microSD thẻ tray.


The right side hosts a single 3.5mm full bộ jaông xã & you’ll also find the power và volume control buttons here. As far as I/O is concerned, that’s it. This is very limiting.

I underst& why Lenovo did this though. The device is incredibly thin & I doubt a full-form size USB port would fit comfortably.

Speaker grills are also present on the sides.

You also get a stylus/pen device that Lenovo calls the Real Pen. It’s bulky, but it works. I’m disappointed that there’s no magnetic clip or some such mounting mechanism on the Yoga Book itself. However, unlike Apple’s Pencil, at least you can clip the Real Pen khổng lồ your shirt pocket. And it won’t roll all over the place.


The Real Pen’s cap is very stiff & it takes a deal of effort to lớn separate the body toàn thân from the cap. This is good because it means that the Pen won’t fall off, but it’s also bad because of the effort involved.

The Pen can also be used lượt thích a real pen, but you need to lớn change tips. This is, again, a convoluted process involving the cap and some amount of pressure. I had lớn consult the user manual khổng lồ figure out how to vị this. What gadget makes you consult a user manual in 2017?

Keyboard, Trackpad and Pen: 6/10

The USP of the Yoga Book is its rather unusual writing surface. At first glance, it looks lượt thích a slab of glass. On closer inspection, you see the outlines of a keyboard và touchpad.

When powered on, the Halo keyboard, as it’s called by Lenovo, lights up. You see the outlines of the keys và touchpad clearly.


Typing on this keyboard is disconcerting at first, but you quickly get the hang of it. However, it’s not a keyboard that’s meant for typing.

My main problem with the keyboard is a lack of any sort of feedbaông chồng. There is a vibration motor that vibrates when you tap a key, but that motor makes more noise than vibration and sounds lượt thích a buzzing bee. The very first thing I did on hearing it was to find a way khổng lồ turn it off.

There’s no visual feedbaông chồng either. I’d have sầu loved it if the keys glowed when you tapped them, or something lượt thích that. Worse still, the audio feedbaông chồng that you get when you type (from Windows) is out of sync with your keystrokes.

I blame the decision to lớn go with an underpowered Atom here, but I’ll address the whole power issue further on in the reviews.


The outlined touchpad can be used khổng lồ control the mouse, & I appreciate Lenovo’s decision khổng lồ keep the touchpad a bit small. While the whole surface is touch sensitive sầu, the mouse will only respond khổng lồ touch inputs on the touchpad. This makes it comfortable lớn rest your palms on the device while typing. Large left & right cliông xã buttons as well as support for Windows’ gestures are a nice addition.

Of course, you can just tap the screen any time you like.

The second mode that the keyboard operates in is, for laông xã of a better word, pen mode. You tap a little pen inhỏ on the keyboard and the entire surface turns inlớn a Real Pen sensitive surface.

This is the Yoga Book’s buổi tiệc ngọt triông xã.


In this mode, the touch surface is now only sensitive sầu to lớn Real Pen inputs. Your fingers & palms are ignored. In fact, when you enable this mode, Windows automatically throws up the option to enable Windows Ink-enabled apps like Onecảnh báo.

I love sầu the fact that the Yoga Book responds on a 1:1 basis when using the Real Pen. If you doodle in the top right corner of the touch surface, your doodle will appear at the top right corner of the screen. The screen, on the other h&, completely ignores the Real Pen and only responds khổng lồ touch đầu vào with your finger. One will never interfere with the other.

This is the magic of Windows Ink and I don’t believe it’s possible on any other platsize. Microsoft deserves kudos for this.

The Real Pen input đầu vào is precise, making writing, sketching và other such actions feel natural. The Pen doesn’t feel as refined as the Apple Pencil, but I’d argue that its response is just as good. The Pen is sensitive lớn pressure, making it a nifty drawing tool.

Sadly, the laptop’s meagre CPU power lets us down in this department as well.

Another trick up the Yoga Book’s sleeve comes in the khung of actual pen input. You can literally place a piece of paper on the touch surface và take notes with the Real Pen (with an ink tip). You’ll have sầu a paper original and a precise digital copy for your archives. Very cool.


And if you’re wondering, no, a normal pen won’t work.

Here’s my problem. I like the Real Pen và I enjoy the ability to lớn sketch. However, a keyboard is absolutely essential, especially on a machine running Windows. The Halo keyboard is a lovely concept, but a laông xã of any kind of proper feedbaông xã và the sluggishness of the system don’t make for even a passable typing experience. The performance issues also mean that sketching isn’t quite as much fun as it could have been.

I’ll put it this way: I intended khổng lồ write this nhận xét on the Yoga Book’s keyboard. I gave up before I’d written a 100 words.

Features: 7/10

The Lenovo Yoga Book is powered by an Intel Atom x5 Z8550 CPU và 4GB RAM. You get an 8,500 mAh battery and 64GB of onboard storage, as well as a micro-USB port & micro-HDXiaoMI jack. The speakers are Dolby certified, the keyboard is a touchpad and you get a good stylus with it.

The screen is a 10.1-inch touch-sensitive LED panel with a resolution of 1920x1200, there are a number of accelerometers present within the device and you get dual-band Wi-Fi 802.11 ac tư vấn.

This is quite a neat package on paper & I think it works, mostly.

The decision lớn go with 4GB RAM is a sensible one; I’ve seen too many devices that are let down by a measly 2GB RAM. 8GB would have sầu been nicer though. 64GB of onboard storage is also rather low & at this price, I expected better. Bear in mind that this device costs Rs 50,000. Phones come with more storage at half the price.

The real killer here is the Hãng sản xuất Intel Atom chip. It’s a 1.4GHz chip that’s really meant for entry-cấp độ devices. As you’ll see later on in the performance section, a lack of power is what leads lớn this laptop’s downfall.

The lack of a USB-A port is very frustrating. Part of the advantage of a máy tính is having the freedom khổng lồ connect USB devices (Looking at you, MacBook Pro!). It’s not a deal-breaker, however, & while I don’t like the decision, I appreciate the difficulty of putting one on the Yoga Book.

Display: 7/10

The 10.1-inch Full HD (1920x1200) is quite nice. It’s a little dull, even on maximum brightness, but the high pixel mật độ trùng lặp từ khóa of 224ppi (the iPad’s retimãng cầu display comes in at 264ppi) means that everything is sharp.


While colours are good, we did notice that blacks were a bit too, well, blachồng. You might think that’s a good thing, but in the course of our testing, we found that the Yoga Book’s contrast ratio is bad, it was the first device lớn earn a zero in our blachồng levels test.

Still, the excellent Trắng levels & laông xã of banding or significant colour bleed means that it scores higher than the Lenovo IdeaPad 110 or Smartron t.Book.

I’m very picky about my displays, which is why I’m complaining, but I don’t think the average person will care very much. It’s not the best of displays, but it’s far from being the worst one.

Performance: 3/10

Performance is tolerable at best. Even basic Windows functions lượt thích opening and closing windows và opening the start thực đơn feel sluggish. The worst part was the lag while typing. There’s nothing more frustrating than seeing your cursor stubbornly stuck in the same place. This is exacerbated by the fact that there’s no actual feedbaông xã from the keyboard.


The deal-breaker for me was Google Chrome. This underpowered máy tính xách tay is good for few things, và I expected đoạn Clip playbaông chồng lớn be one of them. However, đoạn phim playbachồng on YouTube is an infuriating experience. When it works, it’s great, but that rarely happens. On Chrome, resizing the YouTube video clip frame takes forever, the UI gets janky from time-to-time và there were times when I’d hear the audio but the Clip would be frozen in place.

Browsing on Chrome was also a very frustrating and lag-filled experience.

Thankfully, Microsoft Edge is at trang chính on low-end systems và it does sterling work in keeping your browsing experience alive sầu. But who uses Edge anyway? I survive on Google services & if I can’t have sầu Google Chrome, I’d rather not have sầu the device, thank you very much.


If you’re not so concerned, you’ll be fine. Edge works fluidly enough & even YouTube playbachồng isn’t so bad on that browser.

Barring YouTube on Google Chrome, đoạn Clip performance was good. I only tried 1080p files, but even high bit-rate MKV files with H.265 compression worked well. Streaming over Wi-Fi from a NAS was also good, I expect the Wi-Fi 802.11 ac tư vấn had something to vị with that.

The screen was a bit dull, but indoors, it was fine. Paired with its surprisingly loud speakers, the movie watching experience on the Yoga Book wasn’t so bad after all. Speaking of speakers, they’re about 50 percent louder than the speakers on my iPhone 6S Plus & stereo separation is quite apparent.


Our benchmarks place the Yoga Book at the bottom of the pile, with only the Rs 9,999 Compbook Excellance fairing worse.

We noted that temperatures under load crossed 80 degrees, but the CPU would quickly throttle down to lớn a mere 1.6GHz (it should be consistently hitting at least 2.0GHz) khổng lồ bring the temperatures down khổng lồ the low 70s. The passive cooling system is to blame for this.

Thankfully, the device itself doesn’t get too hot.

Battery Life: 9.5/10


At last, some good news! The Yoga Book manages lớn provide a staggering 7.5 hours of battery life in our standard battery chạy thử. Most laptops die at the 3-4 hour mark. 7.5 hours on our test means that you can easily extract a full workday’s performance from the device.

Charging the battery khổng lồ full from zero did take a few hours, but it wasn’t so bad và I just got into the habit of leaving the device charging overnight.

Verdict and Price in India

Treat the Lenovo Yoga Book as an eye-catching indulgence and you’ll be very happy. Expect something more, & you’ll be disappointed.

If you need a truyền thông consumption device, buy a tablet. A cheap Android tablet or an máy tính bảng iPad will serve you better. If you need a workhorse, any máy vi tính with a real keyboard is still better. If you need something to lớn sketch on, get a Microsoft Surface Pro 4 or an Apple Máy tính bảng iPad Pro.

The Lenovo Yoga Book is what it is: A bold take on the 2-in-1, a head-turner, and nothing more.

If you think Rs 49,999 is worth that, then go ahead, piông chồng up one up. For everyone else, there are far better alternatives around.
