Asus Zenbook is a line of consumer-oriented high-endnotebook computers produced byAsus. The first Zenbooks were released in October 2011 asUltrabooks, and the original range of products has since been expanded to models ranging from smaller and power efficient notebooks to high-end and larger laptops with additions like discretegraphics processing units. As of 2024, the Asus Zenbook S serves as the company's flagship notebook computer.^[1][2]

The series is positioned by Asus as part of the thin-and-light segment within the premium consumer market. Asus designed the Zenbooks withbrushed aluminium chassis and high rigidity, rather than plastic, the usual laptop construction material. A pattern of concentric circles on the lids is said to represent ripples in water and reflect the "zen philosophy" that designers wanted to portray when creating the laptops. Asus has also described its design approach as influenced by reductionism, aiming to simplify form while retaining functionality. As of 2024 there are various series including the standard Zenbook, extra slim and light Zenbook S, performance-oriented Zenbook Pro with dedicated graphics cards, convertible Zenbook Flip, dual screen Zenbook Duo, foldable tablet Zenbook Fold and portable Zenbook A.^[3][4][5]

Asus has also developed a proprietary material called Ceraluminum^[6][7][8] (from ceramic and aluminium) for the exterior of some Zenbook laptops.

In 2009 Asus released the UX50V, a 15-inch laptop that was focused on energy efficiency and had a thin profile.^[9] The laptop was rated poorly by reviewers as it under-performed and had mediocre battery life, despite the installed energy efficient hardware.^[10] Although not branded as one, it bore the same "UX" product code as many of the later Zenbooks and was an early foray into theultraportable market. Asus unveiled the UX21 ultra-thin notebook atComputex 2011;^[11] later in October 2011, the UX21 (and a larger version, UX31) were made official under the Zenbook name. The Zenbook line began as Ultrabooks, designed to provide performance in a portable form factor. Sales in the U.S. began on October 12 starting at $999.^[12] The bodies of the Zenbooks are made of aluminium, chosen for its light weight, strength, vibration dampening, appearance and acoustic properties.^[13] Both the bodies and lids areCNC milled andbrushed for appearance.^[13] Reviewers have noted the resulting superior rigidity and complimented the appearance of the Zenbook range.^[14][15][16]

The Zenbook name was proposed by Asus chairman Jonney Shih to reflect the "zen philosophy" applied to the design.^[13] The chief designer, Loewy Chen, had wanted to incorporate design elements from luxury watches into his products for a long time. Zenbooks were the first opportunity to put this into practice,^[13] the crossover being achieved, he said, by "the unfolding of the laptop from the side recalling the elegance of minute and hour hand movements".^[17] The reference to watches is also reflected in the marketing of Zenbooks; Asus published design sketches overlaying an open Zenbook on a watch face, and video advertisements feature similar imagery.^[18][19] The concentric circles on the lid of Zenbooks^[20][21] were intended to look like ripples in water and to reflect "philosophical ideas such as the infinite nature of Zen thinking and self-improvement".^[13][17]

In April 2012, Asus announced a second generation Zenbook, branded as Zenbook Prime, upgraded to run on Intel's newIvy Bridge-based CPUs.^[22] Shortly after it also introduced two lower-cost Zenbooks, as the UX32.^[23]

To preserve space, some Zenbooks use twoPCBs connected by a communications ribbon so it can have ports on both sides of the device, with a heatsink and fan centred between them.^[24][25]

In 2015, ASUS introduced the Zenbook Pro series, featuring models with discrete graphics.^[26] The following year, the Zenbook Flip series was launched as a convertible 2-in-1 line.^[27]

In 2017, Asus debuted ScreenPad with the Zenbook Pro 15 UX580. The ScreenPad replaces the regular touchpad with a colour capactive touchscreen display.^[28] This technology was then in 2019 included in the Zenbook 13 (UX334), Zenbook 14 (UX434) and Zenbook 15 (UX534) and offered optionally on the lower end lineup ofVivoBook S laptops.^[29][30]

In 2018, ASUS expanded the Zenbook line with the Zenbook S series, emphasizing slim-and-light designs, and introduced the Zenbook Pro 15 (UX580) with the industry-first ScreenPad, which replaces the conventional touchpad with a colour capacitive touchscreen display.^[31][32]

In 2019, as a successor the 2018's Zenbook Pro, the Zenbook Duo and Zenbook Pro Duo feature two screens – one at the regular position and the other above keyboard. This second display resulted into the move of the keyboard nearer to the chin and the touchpad to where a numberpad would be similarly to Asus' gaming ROG Zephyrus laptop.^[33]

In 2022, ASUS introduced the Zenbook Fold (UX9702), a foldableOLED device capable of functioning in both tablet and laptop modes.^[34]

In 2024, Asus announced a new Zenbook Duo (UX8406) described as the world’s first 14-inch dual-screenOLED touchscreen laptop.The model featured two full-sized displays with a detachable keyboard, housed between the screens for transport and for use in a conventional laptop configuration. The new Zenbook Duo also included a kickstand to elevate the device for more comfortable use in portrait and landscape modes, and incorporated AI-related capabilities.^[35][36]

ASUS continues to integrate processors such as Intel Core Ultra with AI capabilities andAMD Ryzen AI series, along withOLED displays and the use of sustainable materials. Some Zenbook models are certified under theIntel Evo platform.^[37]

At ASUS,design thinking is a core principle, emphasizing a human-centered approach that prioritizes user needs and experiences.This philosophy informs the development of products through an understanding of user interactions with technology. ASUS designs focus on both aesthetics and addressing real-world challenges, aiming for practical and meaningful innovation.The ASUS Zenbook series exemplifies this philosophy by integrating advanced technology, mechanical engineering, and material research with aesthetic considerations in its design.^[38][39]

The ASUS Zenbook series integrates several design elements and technologies, contributing to its performance, user experience, and appearance. These include materials research, display development, hinge mechanisms, and input features.

Ceraluminum™ is a patented material developed by ASUS and used in the Zenbook series. According to the company, its development involved several years of refinement in color, texture, porosity, and hardness, resulting in a smudge-resistant surface.The material combines ceramic-like hardness with metallic flexibility, allowing for thin and durable laptop designs.It has also been compared to applications in fields such as aerospace and watchmaking.^[8][7][6]

The ASUS Zenbook DUO features a dual-screen design with a detachable Bluetooth keyboard and built-in kickstand. It supports multiple modes of use, including:

• Dual Screen Mode: extending the workspace across two displays for multitasking.
• Desktop Mode: both screens positioned upright with the keyboard detached.
• Sharing Mode: arranged side-by-side for reading or presentations.

The secondary screen is designed to support multitasking and professional creative workflows.^[40][41]

ASUS Lumina OLED is a branding used by ASUS for a category of OLED (Organic Light Emitting Diode) laptop displays, available in series such as Zenbook, Vivobook, and ProArt. These displays are characterized byhigh color accuracy, deep blacks, high contrast ratios, and fast response times. They also include features intended to reduce eye strain and extend display lifespan.^[42]

• EasyLift™ hinge: The EasyLift hinge on the Zenbook A14 is designed to allow one-finger opening while maintaining a stable screen position.^[43]
• ErgoLift hinge: The ASUS ErgoLift hinge is a design used in several laptop series, including the Zenbook and Vivobook lines. The mechanism tilts the keyboard when the lid is opened, creating an angled typing position. It also allows additional airflow beneath the chassis for cooling and provides more space for downward-facing speakers.^[44][45]

• Smart Gesture Touchpad: ASUS Smart Gesture is a touchpad feature available on ASUS laptops, including the ProArt, Zenbook, and Vivobook series. It supports one-finger scrolling as well as controls for volume, brightness, and video playback.^[46][47]

  

• NumberPad: The NumberPad is a feature available on certain ASUS laptops, particularly compact models without a physical numeric keypad. It integrates an illuminated numeric keypad into the touchpad. When activated, LED lights display the layout of a standard numeric keypad for data entry, and when deactivated, the touchpad functions normally for cursor control.^[48][49]

ASUS Zenbook models include a range of I/O ports within a slim chassis, such as USB-A, Thunderbolt 4 USB-C,HDMI, and audio jacks. This allows connection to external devices without the need for additional adapters.^[50][51]

Among the notable models, the Zenbook DUO features an OLED dual-display configuration, intended to improve multitasking workflows.^[52][53][54] The Zenbook A14 is positioned as a lightweight Copilot+ PC with long battery life, suitable for extended daily use. Additionally,^[4] the Zenbook S14 is described as a slim AI PC that combines performance with a compact design.^[55]

The Zenbook DUO incorporates an OLED dual-display configuration, designed to support multitasking workflows.^[52][53][54]

The Zenbook S14/S16 laptop is designed to be slim and lightweight. It uses miniaturized components, lightweight materials (Ceraluminum™), and CNC machining for its construction. The model also includes thermal solutions to manage heat and maintain performance.^[55]

The Zenbook A14 is designed as an ultraportable model, combining lightweight construction, durability, performance, and long battery life. It uses a Ceraluminum™ chassis, cooling systems, and AI integration for performance optimization.^[3][4]

The ASUS Zenbook line has introduced products with varied form factors.^[3] The Zenbook Fold, for instance, includes a foldable OLED display that can shift from a compact size to a larger tablet. The Zenbook Flip offers a 2-in-1 convertible design, functioning as both a laptop and a touchscreen notebook.^[56]

The ASUS Zenbook series has received international recognition from design competitions and technology reviewers, reflecting its role in laptop development.^[57][58] The series is noted for its slim and lightweight form factors combined with high performance, and for a design approach often described as nature-inspired and focused on ergonomics.^[59][60] ASUS Zenbook models have received awards such as the iF Design Award,^[61] Red Dot Product Design Award,^[62] Golden Pin Design Award,^[63][64] IDEA Award,^[65][66] and Good Design Award.^[67]

In technology reviews, the Zenbook series is frequently highlighted for its build quality, OLED display options, and battery performance, particularly within the ultraportable category.^[68] Outlets includingPCMag andLaptop Mag have reported that Zenbook devices offer competitive performance and durability,^[69][70] with some reviews noting longer battery life compared to other laptops in the same class.^[71][72]

The first official ZenBooks, the ZenBookUX21E andUX31E drew comparisons to theMacBook Air and it was regarded as an "excellent rival" byCNET reviewer Andrew Hoyle.^[15][16] Other aspects of the laptops that reviewers liked were theBang and Olufsen speakers, fast boot times due to Asus'BIOS design and the speed of general tasks within theoperating system resulting from theSSD andSandy Bridge processors.^{[136][16][137]} However, the screens drew criticism for their poor contrast ratio, colour accuracy and less than perfect viewing angle, although they were praised for their brightness and the sharpness of the UX31's screen.^{[136][138][139]} Reviewers also noted the shallow key-press of the metal keyboard and lack of backlighting, a feature that Asus did not have time to implement before shipping.^[136][140]

ZenBooks have been generally well received due to their chassis design and appearance as well as the high quality screens used in later models. However, thetouchpad software was found to be erratic, particularly on the early models and some of the models received criticism for their high prices. Some models (such as the UX32) suffer from lockdown when the lithium polymer battery cell gets drained or discharged below its recommended threshold, for example if the device is left on and unattended. The result is that the charger will fail to recharge the battery even when plugged in, leaving the machine in a near-complete unresponsive off-state. The machine can often be revived by pressing the power-on key for 10 seconds, whereupon it will start recharging.^[141]

The new screens on theZenBook Prime were highly praised by reviewers when considering brightness, contrast ratio, viewing angle and colour accuracy, the improvements over previous models being put down to the switch fromTN to IPS displays.^{[140][142][143]} The keyboard also garnered praise for the increased backlighting and improved key travel while theIntel Wi-Fi controller was found to perform better than theQualcomm used in the first generation of Zenbooks.^{[142][144][145]} The Zenbook Primes still received some criticism: the latest version of the touchpad was acknowledged as an improvement over the original Zenbooks, but still irritating,^[146][147] and the sound quality was found to be worse than that with the first generation.^[145][147] Despite these issues, the overall reaction was positive: the UX31A was called "today's best ultrabook" and "the best ultrabook out there" at the time of release.^[144][148]

TheZenBook UX32VD was well received for similar reasons to the Zenbook Prime. The screen, chassis and keyboard again garnered praise although the inclusion of adiscrete GPU was noted as a major selling point. The hybrid drive attracted criticism for its slow performance and the same touchpad issues that the Zenbook Prime had were still present.^[149][150] SLR Lounge criticised the slow hybrid drive and 4 GB of RAM, but suggested replacing them as the option is available, noting that it was an option not often offered on ultrabooks.^[151]

Numerous Zenbook models with resolution specifications of QHD+ (3200 × 1800) and 4K (3840 × 2160) utilizePentile RG/BW displays,^[152][153] which are regarded by some as a "shady practice"^[154] and "sort of cheating".^[155]

As a cheaper option theZenBook UX32A was praised by Chris Martin ofPC Advisor for being "a more affordable luxury", retaining the "premium feel" of the Zenbook range but at a lower price point.^[156][157] The aluminium chassis, which is identical to the UX32VD to keep costs down, was widely acclaimed for its strength and build quality.^{[156][158][157][159][160]} By contrast, theSandy Bridge chip, a previous-generation part at the time of sale, was outlined as a detraction as was the lower battery life compared to the UX31E.^[157][158] Although the screen used was a TN panel and of a lower resolution than the UX32VD or UX31A, it was considered an acceptable compromise for the price.^[157][159] The screen has a matte finish and relatively high brightness which Notebook Check's reviewer, Christian Hepp, found "quite suitable for outdoor use", noting that it had a good contrast ratio but a narrow range of colours.^[160]

TheZenBook UX42VS and UX52VS drew criticism for its high price and lack of touch screen, but the screen quality, keyboard and system speed were praised.^[161][162] The battery life was considered acceptable taking into account the form-factor and the discrete GPU, despite it being significantly shorter than the UX31A.^[163]

AnandTech reviewer Jason Inofuentes found the touch screen to be so superior to the touchpad that he stopped using the touchpad altogether in his trial of aZenbook Touch at the Asus launch event.^[164] Chris Griffith ofThe Australian found that the screen of the UX31A responded well and that the Windows 8 gestures worked predictably, his only criticism being the high price.^[165]

TheZenBook UX430 is commonly reported to suffer from significant coil whine issues.^[166]
