Slim. Stunning. Supreme. ZenBook S is all these, yet so much more. Its elegant sophistication will touch your heart and enhance your prestige, wherever you use it. Its effortless portability, powerful performance and no-compromise connectivity let you get things done without fuss, without drama. And its stunningly innovative design — incorporating our unique ErgoLift hinge — not only sets you apart from the crowd, but lets you work in supreme comfort too. ZenBook S: it’s the laptop you deserve.
Thin and Light
As a seasoned traveler, you’ll appreciate the way ZenBook S slips effortlessly into your bag, with its svelte profile taking up the bare minimum of space and adding hardly any weight. Less bothersome bulk, more room for the really important stuff.
S is for slim
There’s not a gram of material in ZenBook S that doesn’t need to be there: the compact NanoEdge display and premium materials allowed us to reduce every dimension and weight to the minimum, making it thinner and lighter than its rivals for effortless portability. And — in our humble opinion, at least — it’s infinitely more beautiful, too!
Designed for ultimate comfort
With any ZenBook, your comfort is one of our top priorities, ZenBook S goes the extra mile with its exclusive ErgoLift hinge, an engineering masterpiece designed to automatically tilt the keyboard to the most comfortable typing position. But that’s not all: the carefully calculated tilt improves cooling and audio performance, too.
More comfortable typing
A slight positive tilt on your keyboard helps reduce discomfort during long typing stints, something that’s not usually taken into account in laptop design. The innovative ErgoLift hinge on ZenBook S changes all that: it automatically adds a 5.5° tilt to the keyboard when you open the laptop for a comfortable, more desktop-like experience. With a maximum opening angle of 145°, it opens wider than most laptops too, so you have more freedom to choose the best screen angle. And when you close ZenBook S the ErgoLift mechanism is completely hidden, so it doesn’t affect the sleek profile.
More efficient cooling
When the ErgoLift hinge mechanism tilts the keyboard, it also creates an important extra ventilation space that allows more airflow around the underside of the chassis. With this improved ventilation, ZenBook S keeps its cool even when you’re pushing through to meet those tough deadlines.
More immersive audio
The extra space underneath ZenBook S created by the ErgoLift hinge has yet another benefit: it allows the powerful speakers to work at their best, delivering clearer sound with improved bass response.
The art of perfection
Elegance, sophistication and precision craftsmanship are the hallmarks of every ZenBook. The prestigious Deep Dive Blue and Rose Gold color scheme we chose for ZenBook S is luxuriously stylish without being brash, and for a discreetly indulgent finishing touch, we’ve added a gold keyboard backlight and lid logo. ZenBook S doesn’t just steal the show — it owns it.
Deep Dive Blue
Inspired by the magical moment at dawn when the golden rays of the sun first illuminate the ink-blue sky, the luscious Deep Dive Blue finish has contrasting diamond-cut Rose Gold highlights around the edges. This perfect match of hues gives ZenBook S a sublime, understated beauty.
No fuss, no drama
ZenBook S is built to get things done as quickly and efficiently as possible, with no fuss or drama. The latest Intel® Core™ processors mean you’ll enjoy smooth and responsive performance whatever you’re doing, and the state-of-the-art components are all specially selected to ensure you’ll spend less time waiting and more time enjoying.
The latest Intel® Core™ i7 processor
Despite its incredibly slim profile, ZenBook S packs a real punch. It’s crammed with an array of high-performance components, including the very latest Intel® Core™ i7 processor and up to 16GB of RAM, which help it to easily outperform its rivals in benchmark tests.
Less wait, more work
A high-performance solid-state disk (SSD) with a PCIe® 3.0 x4 interface gives ZenBook S the fastest storage available — more than twice as fast as the SSD in an Apple MacBook®5. With an SSD-equipped ZenBook S, you’ll never be kept waiting for the operating system to boot or for applications to load. And with no moving parts, the SSD is also incredibly reliable and quiet.
Fastest memory, best multitasking
In the search for ultimate performance, our engineers chose the world’s fastest RAM for ZenBook S — LPDDR3, clocked at an amazing 2133MHz. Despite its speed, LPDDR3 uses very little power, helping to keep ZenBook S running for longer. And with up to 16GB RAM, your ZenBook S handles multiple demanding tasks without skipping a beat.
A vision of beauty
A laptop as beautiful as ZenBook S deserves equally beautiful visuals, so we’ve fitted it with an ultra-high-definition NanoEdge display with lifelike colors and detail that will take your breath away. We’ve also reduced the bezel width even further, to give you an even more immersive view while keeping ZenBook S amazingly compact. Ultraportable computing has never looked so good.
Our amazing NanoEdge display technology just keeps evolving, and in ZenBook S we’ve made the already-slim bezel even slimmer to give you more display in the smallest space possible. With a higher screen-to-body ratio, there’s less distracting bezel for more immersive visuals.
Immersive 4K UHD display
With 331 pixels per inch, everything on the NanoEdge display is pin-sharp: from the finest details in photos and videos, to the tiniest text fonts. It’s a dream come true for anyone who needs the ultimate visual performance.
A creative touch
With its super-accurate touch control6, ZenBook S is simply amazing for capturing your inspiration. Enjoy effortless creativity with the combination of Windows Ink and the optional ASUS Pen, enhanced by the ErgoLift hinge that opens up to 145° to allow more comfortable touch interaction than standard laptops.
Work longer, charge faster
ZenBook S uses a high-capacity battery that won’t let you down, however long and demanding your working day is. And its fast-charge technology lets you recharge ZenBook S up to 60% capacity in as little as 49 minutes5, so you can be up and running quicker than ever.
For maximum performance, heat needs to be removed as quickly as possible. ZenBook S uses an uprated cooling system incorporating 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 0.1mm-thin walls. An all-new fan housing design with improved airflow gently expels warm air from the interior via hidden vents in the hinge, for efficient, serenely quiet cooling even under full load.
Innovative high-airflow design
To keep ZenBook S perfectly cool at all times, we’ve redesigned the cooling system for even better performance. It includes an innovative liquid-crystal-polymer fan impeller with 71 blades — an increase of 40% — housed in an advanced 3D-curved aerodynamic shroud that’s designed to optimize inlet and exhaust airflow. It’s so good, it can move 13.4% more air than the previous design, and the housing is constructed entirely from tough aluminum with special support ribs for maximum strength and durability.
Your choice of cooling mode
The new Quiet Fan app lets you choose the ideal cooling mode for the task at hand, with balanced and high performance modes. With Quiet Fan enabled, you get balanced performance and a standard fan speed for near-silent computing. Disabling Quiet Fan results in a higher fan speed for those times when you need maximum performance.
Connect fast, connect anywhere
When you’re on the go, no-compromise connectivity is essential. ZenBook S delivers the ultimate speed of Thunderbolt™ 3 in two of its three USB-C™ ports, and all three ports support fast charging, data transfers and display connectivity. And for desktop-grade connectivity, simply connect the handy ASUS Mini Dock.9
Thunderbolt™ 3 ports
Two of the three USB-C™ ports on ZenBook S incorporate the latest Thunderbolt™ 3 technology for versatile, ultrafast connections to all the latest peripherals: it’s up to twice as fast5 as Thunderbolt™ 2 and up to eight times faster5 than USB 3.1 Gen 1. You can power and charge devices too, and the dual 4K UHD external display support lets you create a powerful visual workstation to enhance your productivity or gaming experience. You can even connect an external graphics dock — such as the ASUS XG Station Pro — to give you all the power you need for the latest games and virtual reality (VR) applications.
Mobility without bounds
ZenBook S incorporates ASUS Wi-Fi Master technology, so you’ll enjoy faster and more reliable Wi-Fi connections at greater distances than ever before. This exclusive technology brings you the full benefit of the up-to-6x-faster, MU-MIMO-capable dual-band 802.11ac Wi-Fi in ZenBook S, with speeds of up to 867Mbps5. With Wi-Fi Master, you can enjoy streaming FHD YouTube videos at distances of up to 300 meters or even more. And even when you’re using USB 3 devices — which can cause wireless interference — you can still stream smoothly when you’re up to 225 meters or more5 away from your router, 65 meters farther than on standard laptops without the benefit of Wi-Fi Master!10 Additionally, the MU-MIMO capability11 means you can experience 3x-faster Wi-Fi performance in multi-device environments. Combined with the latest Bluetooth® 4.2 that lets you connect your favorite devices with less impact on battery life, ZenBook S gives you the freedom to do whatever you need, wherever you want to!
Immersive Harman Kardon audio
To give ZenBook S unsurpassed audio capabilities, the ASUS Golden Ear team cooperated with audio specialists Harman Kardon to produce the next generation of ASUS SonicMaster Premium audio technology. The results are astonishing. ZenBook S has two high-quality stereo speakers and surround-sound effects that envelop you with cinema-quality audio. A special smart amplifier ensures maximum volume with minimum distortion for powerful, clear sound. Once you’ve tried it, we think you’ll agree that ZenBook S delivers the most incredible sound you’ve ever heard on an ultraportable laptop.
The Best Windows Experience
One-touch access with Windows Hello
Accessing your ZenBook S couldn’t be easier or more secure, thanks to Windows Hello technology and the fingerprint sensor built into the touchpad. Now there’s no need to type in your password every time to log in — a single touch is all it takes!
Cortana, your long-distance assistant!
Cortana is your voice-controlled digital personal assistant, and the far-field capability of the powerful microphone array on ZenBook S means you can interact reliably from further away — up to 4 meters away even in noisy environments like a kitchen or living room.
Instant resume with Modern Standby
With Modern Standby in Windows 10, ZenBook S is always ready to go in an instant — just like your smartphone! When resuming from sleep mode, Windows 10 wakes in under a second — 3x faster than before5. Modern Standby also lets you continue to get updates and notifications — or even play audio — even when the laptop is in sleep mode.
More comfortable, by design
All too often, laptop keyboards seem to be an afterthought. But not on ZenBook S: its ergonomic keyboard is designed from the start with comfort in mind. It has widely spaced, long-travel keys that feel more like a desktop, and the tops of the keys are gently dished to aid accurate typing. The gentle gold backlight lets you work in any lighting conditions, while remaining easy on the eyes.
Easier access to hardware controls
Attention to every useful detail is a key part of the ASUS design philosophy. We’ve introduced an evolutionary new way of using the humble Fn key to access your laptop’s features, such as the volume or display brightness. In the past, you’d press the Fn key first to use these features: now, the function keys operate the advanced features by default. If you want to access the standard function keys (F1-F12) simply use the Fn key combination.

ASUS Laptop Quality Tests
Ultratough: military-grade durability
ZenBook S meets the ultra-demanding MIL-STD 810G military standard for reliability and durability, undergoing a punishing test regime that includes extended tests for operation in harsh environments including extreme altitudes, temperatures and humidity. It has also passed ASUS internal laptop tests that far exceed the standards set by the industry.
