Zenbook 3 Design Story




ASUS ZenBook 3 UX390UA

To say that ZenBook 3 is a new generation of ZenBook is a huge understatement — it’s ZenBook reimagined for the next era of mobile computing. Every single precision component and every elegantly crafted detail has been completely re-engineered and redesigned to make ZenBook 3 the most sophisticated ZenBook yet. It’s lighter, thinner, stronger, impossibly powerful — and utterly beautiful. Simply, it’s the world’s most incredible laptop. Say hello to ZenBook 3.





Crafted to perfection

ZenBook 3’s design took some serious engineering prowess and craftsmanship to realize. The ultra-thin 11.9mm profile meant we had to invent the world’s most compact laptop hinge — just 3mm high — to preserve its sleek lines. To fit in the full-size keyboard, we had to create a surround that’s just 2.1mm wide at the edges, and we designed the powerful four-speaker audio system in partnership with audiophile specialists Harman Kardon. ZenBook is renowned for its unique, stunning looks, and you’ll instantly recognize the iconic Zen-inspired spun-metal finish on ZenBook 3’s all-metal unibody enclosure — a finish that takes 40 painstaking steps to create. But we’ve added a beautiful twist, using a special 2-phase anodizing process to create stunning golden edge highlights. To complete this sophisticated new theme, we’ve added a unique gold ASUS logo and given the keyboard a matching gold backlight.








Thinner. Lighter. Tougher.

ZenBook has always been the benchmark for thin and light design, and with ZenBook 3 we’ve taken it to a whole new level. Using premium, aerospace-grade aluminum — lighter than standard laptop alloy, but 50% stronger — we reduced the weight to only 910g and honed the profile to an amazingly thin 11.9mm. To keep the display lightweight and ultra-slim, yet tough, we covered it with just 0.4mm of super-strong Corning® Gorilla® Glass 4, which is twice as thin as standard cover glass.





Spectacular display

ZenBook 3 introduces our very first laptop display covered with full edge-to-edge Corning® Gorilla® Glass 4. The ultra-slim bezel is just 7.6mm wide, giving ZenBook 3 a class-leading 82% screen-to-body ratio. More importantly, it gives you a distraction-free view of the stunning 12.5-inch Full HD screen. With its wide 178° viewing angles, superb color reproduction and crisp detail, it really does need to be seen to be believed.




Ultra-realistic visuals

To bring you the ultimate visual experience, ZenBook 3 harnesses the power of our own exclusive display technologies, with optimized hardware and software components combined to deliver the best possible images. The wide 72% NTSC color gamut and TV-grade 1000:1 contrast ratio ensure more-vivid, more-lifelike colors, and ASUS Splendid technology fine-tunes display parameters to ensure superb color accuracy, as well as providing automatic optimization for any kind of image. ASUS Tru2life Video is a remarkable real-time video enhancement technology that optimizes the appearance of every pixel in every video frame, delivering 200% better contrast and pin-point sharpness.





Unbelievably powerful

Our engineers had an almost impossible task when choosing the components for ZenBook 3. Their belief was to create an ultra-thin laptop with unprecedented performance, and despite some tough challenges, they’ve succeeded. The result is an unbelievably powerful laptop, with the latest Intel® Core™ i7 processor, up to 16GB of 2133MHz LPDDR3 RAM, an ultra-fast up to 1TB PCIe® Gen 3 SSD and the latest USB-C port that support display. So there’s no need to worry about what you can or can’t do with ZenBook 3 — it’s practically unstoppable.




Thermal System

The coolest of cool

The problem with fast, ultra-thin laptops boils down to basic physics. To prevent the laptop enclosure itself getting hot, warm air inside needs to be expelled as quickly as possible to the outside world. With ZenBook 3’s mighty Intel® Core™ i7 processor inside, our engineers had to invent a brand-new cooling system using state-of-the-art components such as a liquid-crystal-polymer fan impeller that’s just 0.3mm thick and a copper-alloy heat pipe with walls a mere 0.1mm thick. This innovative cooling system is a mere 3mm thick, and the warm air is gently routed through hidden vents in the hinge for efficient, serenely quiet cooling even under full load.





All-day battery, charged in minutes

A laptop as beautiful and powerful as ZenBook 3 deserves nothing less than all-day battery life, so to achieve its remarkable up to 9 hours autonomy we designed a special high-capacity 40Wh lithium-polymer battery, specially shaped to fit precisely into the impossibly thin profile. We also added fast charging technology that allows you to charge it up to 60% capacity in just 49 minutes.






Mobility without bounds

We live in a wireless world, and ZenBook 3 is fully equipped to give you the very best connections, everywhere. It features the latest power-efficient Bluetooth® 4.1 and dual-band 802.11ac Wi-Fi that’s more reliable and three times faster than the previous-generation 802.11n. And with our exclusive software you can create your own personal data cloud for fast, secure and convenient access to all your files, wherever they’re stored — on your ZenBook 3, on your mobile devices, or in the cloud.




Keyboard and Touchpad

No-compromise productivity

The best ultraportable laptop doesn’t deserve a keyboard that’s an afterthought, and with ZenBook 3 it’s been engineered into the design from the start. The full-size backlit keyboard stretches from edge to edge, with just a 2.1mm bezel at each side, and has a key pitch (the distance between the center of each key) of 19.8mm, the same as most desktop keyboards. And although the keyboard is incredibly slim — 28% thinner than the previous generation, in fact — there’s still an impressive 0.8mm key travel, which is twice as much as some rivals! ZenBook 3’s precision touchpad is cleverly engineered for maximum comfort and accuracy, with a glass covering for smooth control, and incorporating palm-rejection technology, Smart Gestures and handwriting support.





Fingerprint Sensor

One-touch access with Windows Hello

Accessing your ZenBook 3 couldn’t be easier or more secure. With the built-in fingerprint sensor in the touchpad and Windows Hello, there’s no need to type in your password every time to log in. Just a single touch is all it takes!




SonicMaster Premium

Sound that will amaze you

To give ZenBook 3 unsurpassed audio capabilities, the ASUS Golden Ear team and audiophile specialists Harman Kardon joined forces to produce the next generation of ASUS SonicMaster audio technology, and the results are astonishing. An array of four separate high-quality speakers is powered by a smart four-channel amplifier to bring you true surround-sound that envelops you with distortion-free, cinema-quality realism. ZenBook 3 really does give you the most incredible sound you’ve ever heard on a laptop.




Universal Dock (Optional)

Completely connected

Connecting to all your devices and peripherals couldn’t be easier or faster, with ZenBook 3’s next-generation USB-C port. This supports displays, power delivery and data transfer, all via one reversible connector. With the all-in-one USB-C Universal Dock, you also get all the ports you need, including an SD card reader, LAN, VGA, HDMI, standard USB 3.0 and USB-C port for charging. Connecting to all your devices at home or in the office is easy with ZenBook 3.
