Lenovo Yoga E-book 9i evaluate: The world isn’t prepared for dual-screen laptops, however Lenovo is

Every so often, a tool comes alongside and challenges you to think about the viability of a wholly new product class. That’s exactly what Lenovo is doing with the Yoga Book 9i. By changing the standard bodily keyboard with a second show, the corporate is rethinking what a laptop computer can do. In tight confines, you possibly can depend on a digital keyboard or an included magnetic different. However when house isn’t a priority, you possibly can prop the entire system up on its customized folding cowl to create an attractive dual-screen workspace. It’s like a miniature all-in-one PC that’s extremely simple to hold round. And whereas its software program nonetheless wants work and it prices twice as a lot as a normal clamshell, the Yoga E-book 9i is proof that it’s price exploring this new department of the laptop computer’s evolutionary tree.

Design and shows

There’s a profound magnificence to the Yoga E-book 9i’s design. Although the laptop computer’s backside half is a bit thicker than the highest, it appears like Lenovo has boiled the machine right down to its most simple parts: two halves (on this case, screens) joined by a hinge within the center. The twin 13.3-inch shows (2,880 x 1,800) look nice too, boasting OLED panels with wealthy colours and a examined brightness simply shy of 400 nits.


Lenovo Lenovo Yoga E-book 9i


  • Novel design
  • A lot of bundled equipment
  • Higher-than-expected battery life
  • Features as a transportable all-in-one PC


  • Costly
  • Poor dual-screen help in Home windows
  • A lot of bloatware
  • Typing on a touchscreen might be awkward
  • No 3.5mm audio jack

Across the outdoors, the Yoga E-book contains a polished steel body with three Thunderbolt 4 ports, which is good to see on a system this dimension. Sadly for followers of wired audio, you don’t get a 3.5mm audio jack. Fortunately, Lenovo’s 5-megapixel IR webcam is sharper than what you get on most competing gadgets, and holding all the things collectively is the corporate’s signature speaker bar hinge, which is impressively loud and punchy. All advised, regardless of being barely heavier than a typical 13-inch ultraportable attributable to that second layer of glass, it’s nonetheless very simple to hold round.

The remaining items of the Yoga E-book 9i’s equipment are its equipment, which embrace a stylus, a indifferent magnetic bodily keyboard, a folding kickstand cowl and even a glossy journey mouse. The keyboard communicates by way of Bluetooth and has its personal USB-C port for charging. Regardless of its dimension, it doesn’t really feel cramped and gives extra key journey than you may count on. Throughout transport, the quilt wraps across the keyboard to maintain it protected, whereas Lenovo’s Digital Pen 3 might be stashed within the connected loop. 

The mouse is the odd one out as a result of whereas it is a useful inclusion, it’s additionally reasonably primary (its solely noteworthy attribute is having a toggle on the underside for shortly switching between two paired gadgets). Plus, it does not connect to the remainder of the system in any manner. Nonetheless, what you possibly can create while you put these items collectively is when issues get actually fascinating.

A dual-mode machine

In clamshell mode, the Yoga E-book 9i seems to be and features like an everyday laptop computer. However after all, it’s lacking a discrete keyboard and touchpad, so what do you do while you want them? That’s simple, you simply faucet eight fingers on the underside panel and immediately you get digital stand-ins. And for occasions while you solely have to mouse round, you should use a three-finger faucet as a substitute, which summons a floating touchpad that leaves room for Lenovo’s widgets (climate, information, and so forth.) or the rest you’d wish to put down there.

The Yoga Book 9i's stacked display setup might be its most useful mode, as it lets you keep a big project open up top while reserving the bottom screen from email, messaging and more.

Surprisingly, typing on a touchscreen isn’t as dangerous as you may suppose. Don’t get me unsuitable, it’s nonetheless not practically as quick or correct as utilizing a bodily keyboard. Nevertheless it’s serviceable, so long as you’re prepared to make some changes. You may’t slam your fingers down as a result of there aren’t any switches or precise keys with depth to cushion each strike and you must be extra conscious of when your fingers begin to drift lest your sentence devolves right into a jumble. However after a bit of observe, I’m in a position to hit 60 to 65 phrases per minute, which is down from round 85 wpm usually. As for mousing, the tackiness of the glass means swiping round isn’t fairly as fluid both. However that’s OK, as a result of for those who don’t need to rely completely on a digital keyboard or touchpad, you don’t must.

Dropping Lenovo’s keyboard on the underside display immediately converts the Yoga E-book right into a extra conventional setup. The magnets inside even assist align it correctly. From there you possibly can kind away on bodily keys for those who choose. Simply don’t overlook to take away the accent earlier than you shut the lid.

The Yoga Book 9i's side-by-side dual-screen mode is great for being able to reference sources while writing.

What’s most spectacular concerning the Yoga E-book 9i’s is its skill to remodel into a transportable all-in-one PC when it’s propped up on its kickstand cowl. On this mode, there are two choices for its shows: a stacked setup with one display on high of the opposite and a side-by-side association. Each configurations have their makes use of. Twin portrait-mode panels are nice for shortly referencing supplies like spec sheets whereas writing. Alternatively, the vertically stacked orientation is great for protecting an essential challenge open up high whereas the underside display is reserved for electronic mail or messaging apps.

No matter your choice, merely being able to make use of two shows on a tool offers the Yoga E-book 9i a novel benefit over just about each regular laptop computer. Positive, you possibly can recreate an analogous state of affairs utilizing a bunch of add-ons, but it surely’s by no means going to be fairly as glossy.

Software program

The most important draw back to the Yoga E-book 9i is that whereas its {hardware} is strong, its software program is hit and miss. Lenovo makes an attempt to mitigate this with its Consumer Heart, which does a terrific job of showcasing the laptop computer’s dual-screen options and is a simple place to regulate settings like show modes, brightness and extra.

There's no arguing that typing on a virtual keyboard takes a lot of getting used to.

Sadly, even with the additional help, it’s clear Home windows 11 isn’t designed for laptops like this. Generally when launching full-screen apps like a recreation, the Yoga E-book will get confused and places the window on the unsuitable panel. Different occasions, like while you’re putting in a program or logging in, a immediate pops up that fully disables the decrease show, which is form of annoying while you’re counting on a digital keyboard and touchpad. I can perceive that it is onerous to optimize software program while you don’t have a tool to check issues on. Besides, there’s no hiding that this creates a stilted expertise in comparison with a normal laptop computer, and for those who’re contemplating shopping for a Yoga E-book 9i, it is a fact you’re going to must stay with (a minimum of for now).


Packing an Intel Core i7-155U chip, 16GB of RAM and 512GB of storage, the Yoga E-book 9i can deal with most productiveness wants. Even when multitasking throughout each shows, efficiency felt comparatively snappy. Nonetheless, for those who’re planning on repeatedly doing extra demanding issues like video modifying, you’ll most likely need a beefier machine. On our video encoding check, the laptop computer took a minute and a half to transform a one-minute film trailer from 4K to 1080p. That’s not nice when in comparison with programs with sooner chips that may carry out the identical activity in 30 to 40 seconds.

Battery life

For a small system with dual screens, the Yoga Book 9i still features three USB-C ports with Thunderbolt 4. Unfortunately, it doesn't come with a 3.5mm audio jack.

Even with a comparatively massive 80Wh battery, for a system with two screens, the Yoga E-book 9i fared higher than anticipated on our normal video rundown check. It posted a time of eight hours and 12 minutes, which is a pair hours shorter than conventional similarly-sized rivals just like the Asus ZenBook S 13 (10:39). Nevertheless it’s longer than what you get from extra highly effective thin-and-light gaming notebooks, which regularly battle to get north of 5 hours on a cost.

Wrap up

As the primary laptop computer to function two shows, the Yoga E-book 9i is a reasonably divisive machine. Beginning at $2,000, not solely is it actually costly, its efficiency can be slower than extra conventional rivals on this value vary. Nonetheless, for individuals like me who continuously yearn for extra display actual property after I’m away from house, Lenovo has created one thing that’s greater than the sum of its components. When house is restricted, the Yoga E-book 9i’s clamshell mode feels proper at house on an airplane tray desk. However when it isn’t, it could actually increase into a transportable dual-screen workstation–full with all of the fixings of your desktop at house. And when you must pack up, all the things collapses right into a neat, semi-self-contained bundle that matches within the smallest of laptop computer baggage.

One of the best things about the Yoga Book 9i is that despite having two screens, it collapses down into a neat semi-self-contained bundle that's really easy to fit in a bag.

The Yoga E-book 9i is a nifty little transformer that’s extra partaking than something Michael Bay has directed within the final twenty years. With how little laptops have modified lately, it feels just like the Yoga E-book has much more room to develop within the years to come back. Positive, it’s nonetheless a bit awkward, however as the start line for a brand new kind of pocket book, Lenovo’s debut dual-screen convertible has me satisfied.
