TAIPEI, Taiwan, May 24, 2022 — ASUS today announced ExpertBook B9, the world's lightest 14-inch business laptop1, meticulously crafted with industry-leading innovations and enterprise-grade security to deliver executive-level excellence.

Weighing a mere 880 grams and measuring just 14.9 mm thin, ExpertBook B9 is crafted for premium perfection, empowering elite users to take charge of the business world in style. Its sleek, minimalist and precision-machined chassis pushes the limits of lightness for ultimate portability, with a magnesium-lithium alloy lid that delivers luxury and toughness without equal — resulting in the engineering marvel of a 14-inch laptop that is lighter even that many models with smaller 13-inch displays.

ExpertBook B9 is built for serious travel with an amazing all-day battery life of up to 16 hours, and is engineered with many cutting-edge technologies to improve on-the-go work efficiency and provide enterprise-grade security to keep confidential data safe.

Extremely portable, powerful and tough — it's tested to US military-grade durability standards — ExpertBook B9 is the ideal partner in the corporate world, and the new benchmark for elite business laptops.

Engineered for business executives

Crafted from premium magnesium lithium-alloy, ExpertBook B9 weighs a featherlight 880 g and is a mere 14.9 mm thin for exceptional portability that’s always ready. Super-slim bezels enable the clear and bright 14-inch display to fit in 13-inch-class chassis, making ExpertBook B9 extremely compact. The result is the world's lightest 14-inch business laptop, expertly designed and engineered and precision-milled to aesthetic perfection, making it the first choice for business elites who both need and expect the very best for everything they do.

ExpertBook B9 will never let the user down throughout the business day or a long-haul flight. It provides all-day battery life — up to an amazing 16 hours — on a single charge. On top of that, fast-charge technology lets the user accelerate battery capacity up to 60% in as little as 44 minutes, so they're up and running in no time.

ExpertBook B9 is ideally suited to hybrid working, with features such as its AI-enhanced webcam for high-quality video calls, ASUS AI noise-canceling technology for crystal-clear conference calls, powerful Dolby Atmos® multi-dimensional audio.

Enterprise-grade power and security

Powered by up to 12th Gen Intel Core vPro® i7 processor with Iris Xe graphics, ExpertBook B9 is built for business and delivers the fast and responsive performance you need to get the job done. It’s also packed with robust enterprise-grade features to delivers security that’s fit for business — offering serious safety and protection for this premium device and, as importantly, the priceless data it contains.

The NFC reader integrated into the ASUS NumberPad means logging in to ExpertBook B9 can be as simple, swift and secure as the swipe of an authorized card.

ASUS AdaptiveLock detects the user's presence and uses an integrated infrared camera to recognize their face and log them in without lifting a finger. The moment they step away, ExpertBook B9 automatically locks to protect both the laptop and its data. There's also a physical cover that can obscure ExpertBook B9’s webcam when needed for an assurance of instant privacy when the webcam is not in use.

ExpertBook B9 has built-in biometric security, with a fingerprint sensor for easy access. Users can just tap the button to log in — with no difficult-to-remember passwords or PIN required.

A discrete TPM 2.0 chip securely stores authentication information used by software, such as passwords or encryption keys, to protect important data and transactions. User details remain encrypted, virtually eliminating the risk of leaks through hacking.

Finally, an integrated Kensington lock slot allows ExpertBook B9 to be physically secured in unsupervised locations.

Comprehensive connectivity

Despite its thin profile, ExpertBook B9 is loaded with I/O ports that allow users to stay productive anywhere, and help ensure an outstanding remote-working experience. These include cutting-edge Thunderbolt 4, the next generation of the universal cable-connectivity solution that offers support for the next-level USB4® interface, 40 Gbps data transfer speeds, 4K display output, and fast charging. ExpertBook B9 supports up to three 4K external displays. The laptop also offers USB Type-A and an HDMI output, wired network connectivity with a MAC address pass-through for easy device management, and the latest ultrafast WiFi 6E enhanced for speed and stability by ASUS WiFi Master technology.

Precision-milled, military-grade durability

To create ExpertBook B9’s precision-cut lid and complex keyboard surround, a high-precision CNC-milling process is used to shape single pieces of solid metal. This reduces unnecessary internal voids, rendering the entire chassis tougher and stronger than is possible using traditional metal-stamping methods.

This process, along with the use of magnesium-lithium alloy in the lid and structural reinforcement for increased chassis strength, enables ExpertBook B9 to meet the industry-leading MIL-STD 810H US military standard — in addition to undergoing extensive and stringent in-house testing, including panel-pressure, shock and drop tests.

In short, ExpertBook B9 is expertly engineered to shrug off the rigors of everyday business life.

Engineered with the environment in mind

ASUS is committed to creating a sustainable future, so ExpertBook B9 is engineered with consideration for its overall environmental impact — from manufacturer to eventual recycling. With both ENERGY STAR® 8.0 and EPEAT™ Gold certification, ExpertBook B9 delivers superb energy efficient to minimize long-term running costs. Even the packaging is environmentally-friendly, with ExpertBook B9’s Forest Stewardship Council (FSC)-certified accessory box able to transform into a laptop stand for instant ecological elevation.
