Its back cover is still using a single piece of aluminum alloy plate, the YOGA 920 with the hidden air inlet and outlet design and the back cover without any cooling holes. There is no hole to solve the antenna problems, and it only has small holes are provided for JBL speakers on both sides of the lower part.

Unscrew ten screws securing the back cover. You can easily remove the cover. You can see that the layout of the whole interior is simple and clear, and there is no messy cable arrangement. The overall black style has Macbook’s style.

Before continuing to disassemble, we need to disconnect the battery connector from the motherboard.

It may be due to the thinning of the body. The battery capacity is slightly reduced. The battery capacity reaches 70-watt hours in the case of maintaining the 700Wh/L high-density cell design.

After the battery is removed, it is also obvious that the YOGA 920 cable is much tidy than the YOGA 910’s.

The speaker is larger than the previous generation. It also makes YOGA 920 speakers sound better.

The touch panel is covered with a thin glass, which can improve the touch feeling. There is also a metal plate on the back to ensure the stability of the point when touching the touchpad.

Take off the touchpad. You can see the two noise reduction microphone cable, can be said to be quite neat.

Remove one screw securing the fingerprint module.

The fingerprint module provided by Synaptics.

The I/O logic board connection cable

This I/O logic board integrates a power button and a one-button recovery button, the power button and the motherboard separate design is conducive to reducing maintenance costs.

Yoga 920 and Yoga 910 using the same wireless card, the antenna cable design is basically the same as the Yoga 910.

The screen cable hidden in the LCD hinges has been the practice of several generations, the screen cable, and camera cable together as one, placed in the center of the three-section LCD hinges. It will not affect LCD hinges 360°movement at the same time, but also ensure that the cable will not be over-bending.

Disconnect all cables and screws. You can remove the motherboard, and you can see the biggest difference of the sixth generation YOGA motherboard, a total of three points: 1. Use dual copper tube; 2. 16GB memory onboard on the same side of the motherboard, and covered by the metal shield; 3. SSD need to remove the motherboard before you can replace.

Before removing the heat sink module, we first need to disconnect the fan cable.

We split the fan to make a close-up of the fan blade.

Because the fan’s metal blade is very thin, which is conducive to improve the density of fan blades, to bring greater air intake and air flow.

Remove the metal shield. You can see eight memory particles evenly distributed on the motherboard, constitute the memory capacity of 16GB.

The back of the motherboard has two important chips, namely: Realtek ALC3268 sound card chip is very common in a laptop, but the Realtek ALC1304 is less common.

After removing all the screws securing the LCD hinge, the LCD screen can be separated from the motherboard.

After you remove the motherboard, you can access the keyboard. It is fixed by a lot of screws.

Very informative, but I am still terrified to atack a disassembly myself. Question: my Yoga 920 has 2 sticky keys (1/! never works and m/M works intermittently, getts stuck, etc.), and was told to replace the keyboard. It seems so wrong after only 14 months but… whatever. Of course, if there is another, simpler possibility to check, please tell me. But assuming there isn’t, is it best to buy a genuine Lenovo keyboard or some other aftermarket option? And what kind of time is reasonable to be billed for installing it? I got a quote for 3-4 hours, which seems excessive. Thanks!

Lenovo's Yoga design has been copied by many manufacturers over the years, and if imitation is the sincerest form of flattery, then their industrial designers are geniuses worthy of the highest praise (in fact they are pretty awesome). But that imitation poses a problem for Lenovo since you've now got a host of similarly designed laptops to choose from--the HP Spectre x360, Toshiba Satellite Radius models and Asus Flips to name a few. Can Lenovo fend them off with their 4th generation model, the Yoga 900 Windows 10 convertible Ultrabook? The Yoga 900 replaces the Yoga 3 Pro, a machine whose industrial design was definitely praise-worthy, but whose Core M CPU felt less than Pro. The 900 brings back the power with Intel 6th generation Skylake dual core CPUs, and at launch the Yoga 900 is available only with the more powerful Intel Core i7. The design is very similar to the Yoga 3 Pro, and that's a good thing because it's one of the thinnest and lightest convertibles on the market. The watchband hinge is attractive and unique. Better yet, it's robust and last year's Yoga 3 Pros with the same hinge have held up well.

Design and Build

The Yoga 900 is a premium Lenovo laptop aimed at consumers (ThinkPads target business users). Thus it's more daring and stylish than the unassuming black rectangle that is a ThinkPad. The machine is available in gold and my old favorite Clementine orange as well as the duller and more conventional silver. The sides and keyboard deck are rubbery black that feels great and is grippy. Those rubbery sides are also good for absorbing impacts--if you're like me, and manage to bump door jambs and airline seat backs when toting the laptop, then this is a wonderful thing. They also create more grip and stability when using the Yoga in tent mode. Unlike a ThinkPad, the Yoga won't double as a self-defense weapon, and it will likely dent, rather than the hardwood floor, if you drop it. Again, it's not business rugged, it's consumer chic. It's not delicate, just typical of consumer oriented construction.

This isn't a seriously classy unibody machine carved from a block of aluminum like the 13' MacBook Pro or magnesium alloy like Surface Book. While it's unfair to expect a Yoga to be like a ThinkPad (different model lines, different promises), with a starting price of $1,200 and an as-reviewed price of $1,400, the Mac and Surface Book are fair competition. The Yoga looks great, but it doesn't look like the quality piece that those two do. In fact, the similarly priced HP Spectre x360 looks and feels more high end too. It's not that the Lenovo looks cheesy--anything but! It's just that materials and a high end finish (at least on our silver model) aren't where your money is going. Instead, Lenovo puts the chic into the once lowly hinge. They started with the Yoga 3 Pro that introduced the watchband hinge, and it's back here and better--it's tighter and is now silent when you open and close the laptop. It's interesting that hinges are becoming a thing--first the watchband hinge and now Microsoft's snaky fulcrum hinge. Anything is fair game when trying to jazz up a laptop without compromising ergonomics or sturdiness. The watchband hinge certainly is distinctive and striking, and more important--it works well.

The Yoga 900 feels fairly sturdy and the frame is rigid with no flex, though the removable bottom aluminum panel has some flex and the keyboard deck sounds slightly hollow when typing or thumping on the very pleasant trackpad. Again, it's not a cheaply made machine, but it doesn't exude high end. There's a payoff for the lighter and thinner panels though--this is an insanely light and thin laptop. In fact, since convertibles, aka 2-in-1s weigh even more than laptops due to more complex mechanisms and required extra reinforcement, we're even more impressed with the 2.8 lb. weight (yes it gained a few ounces vs. the 2.6 lb. Yoga 3 Pro, and that's fine with us). The Yoga 900 is so slim you might mistake it for a pure tablet at first glance. The charger is even more compact and light vs. traditional laptop bricks. It's a portable lover's dream.

Cool Customer

The two internal fans and airy spaces inside mean the Yoga 900 is a fairly cool laptop. The bottom gets warm but never burning hot, and it's noticeably cooler than the Spectre x360 with Core i7 when both are pushed hard with gaming or video export. The fan is silent when doing productivity work and is audible when gaming, should you push it to the limits with GTA V or Battlefield 4, but it's not vacuum cleaner loud and any slim laptop will run the fan at max speed when gaming.

Ports: USB-C is Here

The Lenovo tapers with a faint hint of a curve toward the front, and the rear needs to be thicker to house the USB ports (it's still slim at the rear). Most ports are on the left: charging (using Lenovo's dual purpose charging + USB 2.0 port), USB 3.0, USB-C 3.1 and a full size SD card slot. The right side has another USB 3.0 port, the power button, 3.5mm combo audio, Novo button (for OneKey Recovery) and screen rotation lock. Note there's no HDMI or mini DisplayPort, so you'll need to source USB-C to HDMI or DisplayPort cables, just like 12' MacBook owners. Happily, unlike that Mac, USB-C isn't your only port!

Used Lenovo Yoga 900

13.3' QHD Display

There's good news and bad news. First the good news: the Lenovo Yoga 900 has a very high resolution 3200 x 1800 display, as did its predecessor. Windows 10 and many desktop programs now handle hi-DPI displays well, so you'll enjoy sharper images with less zooming out in Photoshop and in video editors. The display is made by Samsung, and from what we can tell it's a PLS (like IPS display but with a Pentile matrix). There are no skewed yellows here as with the Yoga 2 Pro and its older generation Samsung QHD panel, and color gamut is good at 96% of sRGB and 75% of Adobe RGB. Color calibration from the factory favors increasing perceived brightness and blues, as do many laptops in this price category (calibration brings it nicely in line). Brightness is good at 300 nits, and the ambient light sensor isn't too twitchy (you can disable auto-brightness if you like).

The bad news: at first look, particularly after reviewing the very high end display panels used in Surface Pro 4 and Surface Book, the Yoga's panel didn't impress. Our usually colorful and sharp desktop backgrounds and test photos lacked a little clarity and pop. Once we ran tests with our Datacolor Spyder colorimeter the culprits were clear: unimpressive contrast and an astronomically high black point. Contrast is just 300:1 and black levels registered at 1.36--I can't remember testing a panel with a black level above 1.0. Lower numbers are better here since it indicates how much light transmits when displaying black. Competing products range from 0.28 to 0.56, with most hovering around 0.39. What does this mean to you? Blacks look gray when brightness is turned up and contrast isn't high because that requires not just high brightness (which we have here) but deep blacks. Text loses a bit of its sharpness when contrast isn't high, but at 50% brightness, it still looks fairly crisp.

Where does that leave you? If you're not a graphics pro, hobby photographer or content producer, then the display is pleasing enough. Photos and videos look colorful and bright. They're simply lacking the contrast and crispiness of the better panels in the $1,000 and up Ultrabook space. Our other complaint? The bezels are large, particularly the bottom bezel. I actually don't like tiny bezels on tablets because they leave no room to hold the machine, but that bottom bezel is simply unattractively large.

Lenovo Yoga Ram Upgrade

The display supports 10 point multi-touch but it does not have an active digitizer for pen use. You can use a capacitive stylus like those made for the iPad and Android tablets, but it's not as precise as a display purpose-built for pen use, and you won't get palm rejection (the ability to rest your hand on the glass while writing and drawing).
