ASUS Announces ExpertBook B3 Flip (B3402)


TAIPEI, Taiwan, September 22, 2021 — ASUS today announced ExpertBook B3 Flip (B3402), a powerful and versatile convertible laptop designed for both work and learning.
ExpertBook B3 Flip is built to embrace the new normal — hybrid working and learning. It's the best companion for teachers and students, and the perfect colleague for business users and pros. With its versatile and tough design, studying or working everywhere is no longer a dream.
B3 Flip is equipped with a 360° any-position hinge for total display flexibility, a world-facing camera1 for a new perspective, and a garaged stylus2 for simple, intuitive input. It includes several convenient protection features, including ASUS Antibacterial Guard3 , and a TÜV Rheinland-certified4 display for everyday eye care.
WiFi 6 (802.11ax)5 is enhanced by ASUS WiFi Master technology6 for faster, more stable connections, and it's also supplemented by an optional fast 4G LTE nano-SIM7 for fast and portable connectivity. Two-way AI-powered noise-cancellation technology and noise-reducing cameras ensure excellent remote learning and conferencing experiences.

Versatility for the new normal

The versatile ExpertBook B3 Flip has a 360° any-position hinge that gives it unrivaled flexibility for work or learning: it can be used in tablet mode for taking notes and studying, or in tent mode for easy revision and taking photos. Stand mode gives everyone the perfect view in meetings or presentations.

When drawing, taking notes, or marking up documents, the optional garaged stylus lets users get every detail just right. The convenient built-in holder keeps the stylus to hand, reduces the risk of loss, and charges the stylus: a 15-second charge gives enough power for 45 minutes of use, so the user's workflow will never be interrupted.

B3 Flip includes a standard user-facing webcam, along with a special 13 MP world-facing high-resolution camera1 located on the keyboard surround just below the display — an ideal position that allows users to capture photos and videos in tent mode and tablet mode. This unique dual-camera arrangement overcomes the limitations of single-camera devices, allowing users to capture photos and videos in any mode for any task. This in turn empowers students to explore and learn in totally new ways, and permits professionals and workers to multitask more efficiently.

All-round speed and reliability

Built to allow safe, secure and speedy data connections everywhere for work or learning, ExpertBook B3 Flip includes fast 4G LTE mobile data connectivity. It also offers up to the latest WiFi 6 technology that delivers ultrafast and stable speeds for online learning and super-smooth business meetings, and which is enhanced with ASUS WiFi Master technology for faster and more reliable WiFi connections at greater distances than ever before.
Life on the road is tough, so B3 Flip is designed to both meet and surpass exacting industry durability standards — including the ultra-demanding MIL-STD 810H US military standard8 . It’s built to survive every extreme, from freezing temperatures to the searing heat of desert storms, and from high-speed shocks to everyday bumps. B3 Flip also undergoes stringent and industry-leading in-house testing, including panel-pressure, shock and drop tests for an assurance of serious durability. The keyboard is reinforced with an internal bracket, and it also has a water-resistant layer9 that can cope with liquid spillages of up to 330 cc without harm9 .

Full protection

To keep ExpertBook B3 Flip hygienic, the keyboard, touchpad, and palm rest are all protected with ASUS Antibacterial Guard antibacterial treatment. This has been scientifically shown by the internationally-recognized ISO 22196 standard to inhibit the growth of bacteria by in excess of 99% over a 24-hour period. ASUS Antibacterial Guard is also made to withstand alcohol-based cleaning products and hypochlorous acid water10 , so it's easy to keep the surface of B3 Flip clean and sanitary — limiting the spread of harmful bacteria.
B3 Flip’s two-sided, slim-bezel, multitouch screen provides intuitive input for modern learning and working experiences. The display is also certified by TÜV Rheinland for low blue-light emissions, so users can study or work without worrying about their eyes being harmed by blue light.

Built for work or learning11

The powerful ExpertBook B3 Flip ensures smooth multimedia learning and makes light work of all business tasks, courtesy of its up to 11th Generation Intel® Core™ i7 processor and Intel Iris® Xe graphics, which deliver quick and responsive computing with lively graphics performance. It also features onboard memory and a SO-DIMM slot for upgrading memory up to 48 GB — so it’s ready for everything, now or in the future.
To level up remote learning and professional conferencing, B3 Flip has two-way AI noise-canceling technology that employs sophisticated machine-learning techniques. The technology includes both an upstream function to filter noise around the speaker, and a downstream function to eliminate noise from the person at the other end of the conversation.
Video-conferencing and remote-learning experiences are also enhanced by the innovative 3D noise-reduction (3DNR) technology on B3 Flip's webcam. This reduces up to 94% of the random noise that naturally affects any camera11 , especially in low-light situations, greatly enhancing image quality without affecting exposure or detail levels.

3The antibacterial treatment is tested by an independent third-party laboratory according to the ISO 22196 standard (measurement of antibacterial activity on plastics and other non-porous surfaces), using bacterial cultures that include Escherichia coli and Staphylococcus aureus, with an antibacterial activity (R) result of R > 2. R = 2 indicates a 99% reduction in bacterial activity compared to an untreated surface

4The antibacterial treatment is registered by the US EPA and authorized under EU BPR.

9ASUS ExpertBook B3 Flip keyboard is spill-resistant, not waterproof. Water damage is possible if the product is submerged or exposed to large amounts of liquids for long periods of time. ASUS standard limited warranty does not cover problems resulting from accidents such as water damage. To prevent water damage resulting from large spills or other accidents, ASUS recommends turning off the notebook, then tilting the laptop to drain away the excess liquid, wipe off and let it dry for at least 24 hours.

10ASUS internal tests show that ASUS ExpertBook B3 Flip can be safely cleaned and wiped using hypochlorous acid water or alcohol from a spray bottle. Individual sprays of up to 3 cc do not affect the performance of the antibacterial treatment.
