Zenbook

First Zenbooks

In 2009 Asus released the UX50V, a 15-inch laptop that was focused on energy efficiency and had a thin profile. The laptop was rated poorly by reviewers as it under-performed and had mediocre battery life, despite the installed energy efficient hardware. Although not branded as one, it bore the same "UX" product code as many of the later Zenbooks and was an early foray into the ultraportable market. Asus unveiled the UX21 ultra-thin notebook at Computex 2011;[4] 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.[5] The bodies of the Zenbooks are made of aluminium, chosen for its light weight, strength, vibration dampening, appearance and acoustic properties. Both the bodies and lids are CNC milled and brushed for appearance. Reviewers have noted the resulting superior rigidity and complimented the appearance of the Zenbook range.[6] The Zenbook name was proposed by Asus chairman Jonney Shih to reflect the "zen philosophy" applied to the design. 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, the crossover being achieved, he said, by "the unfolding of the laptop from the side recalling the elegance of minute and hour hand movements". 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. The concentric circles on the lid of Zenbooks[7][8] were intended to look like ripples in water and to reflect "philosophical ideas such as the infinite nature of Zen thinking and self-improvement".

In April 2012, Asus announced a second generation Zenbook, branded as Zenbook Prime, upgraded to run on Intel's new Ivy Bridge-based CPUs.[9] Shortly after it also introduced two lower-cost Zenbooks, as the UX32.[10]

To preserve space, some Zenbooks use two PCBs connected by a communications ribbon so it can have ports on both sides of the device, with a heatsink and fan centred between them.

Recent history

In 2015, ASUS introduced the Zenbook Pro series, featuring models with discrete graphics.[11] The following year, the Zenbook Flip series was launched as a convertible 2-in-1 line.[12]

In 2017, Asus debuted ScreenPad with the Zenbook Pro 15 UX580. The ScreenPad replaces the regular touchpad with a colour capactive touchscreen display.[13] 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 of VivoBook S laptops.[14][15] 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.[16][17]

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.[18]

In 2022, ASUS introduced the Zenbook Fold (UX9702), a foldable OLED device capable of functioning in both tablet and laptop modes.[19] In 2024, Asus announced a new Zenbook Duo (UX8406) described as the world’s first 14-inch dual-screen OLED 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.[20][21]

ASUS continues to integrate processors such as Intel Core Ultra with AI capabilities and AMD Ryzen AI series, along with OLED displays and the use of sustainable materials. Some Zenbook models are certified under the Intel Evo platform.[22]

Ceraluminum™

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.[25][26][27]

Dual-screen design

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:

The secondary screen is designed to support multitasking and professional creative workflows.[28][29]

• 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.

ASUS Lumina OLED

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 by high color accuracy, deep blacks, high contrast ratios, and fast response times. They also include features intended to reduce eye strain and extend display lifespan.[30]

Hinges

• EasyLift™ hinge: The EasyLift hinge on the Zenbook A14 is designed to allow one-finger opening while maintaining a stable screen position.[31]
• 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.[32][33]

Input features

• 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.[34][35]Smart gesture touchpad.jpg
• 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.[36][37]

Full I/O ports

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.[38][39]

Zenbook DUO

The Zenbook DUO incorporates an OLED dual-display configuration, designed to support multitasking workflows.[40][41][42]

Zenbook S

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.[44]

Zenbook A

The Zenbook A14 /A16 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.[1][43]

The ASUS Zenbook line has introduced products with varied form factors.[1] 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.[45]

Earlier models

The new screens on the ZenBook 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 from TN to IPS displays. The keyboard also garnered praise for the increased backlighting and improved key travel while the Intel Wi-Fi controller was found to perform better than the Qualcomm used in the first generation of Zenbooks. 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, and the sound quality was found to be worse than that with the first generation. 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.

The ZenBook UX32VD was well received for similar reasons to the Zenbook Prime. The screen, chassis and keyboard again garnered praise although the inclusion of a discrete 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.[131][132] 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.[133]

Numerous Zenbook models with resolution specifications of QHD+ (3200 × 1800) and 4K (3840 × 2160) utilize Pentile RG/BW displays, which are regarded by some as a "shady practice"[134] and "sort of cheating".[135]

As a cheaper option the ZenBook UX32A was praised by Chris Martin of PC Advisor for being "a more affordable luxury", retaining the "premium feel" of the Zenbook range but at a lower price point.[136][137] The aluminium chassis, which is identical to the UX32VD to keep costs down, was widely acclaimed for its strength and build quality.[136][138][137][139][140] By contrast, the Sandy 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.[137][138] 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.[137][139] 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.[140]

The ZenBook UX42VS and UX52VS drew criticism for its high price and lack of touch screen, but the screen quality, keyboard and system speed were praised.[141][142] The battery life was considered acceptable taking into account the form-factor and the discrete GPU, despite it being significantly shorter than the UX31A.[143]

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 a Zenbook Touch at the Asus launch event.[144] Chris Griffith of The 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.[145]

Recent models

The ZenBook UX430 is commonly reported to suffer from significant coil whine issues.[146]
