USER EXPERIENCE
Designed for excellence
From eye care to comfortable typing, ExpertBook B3 Detachable offers excellent features to improve everyday experiences, including plenty of innovative features and enhancements that boost productivity and comfort.
ASUS ANTIBACTERIAL GUARD
The surface of any laptop harbors thousands of potentially harmful bacteria. To keep your ExpertBook B3 Detachable hygienic, the keyboard, touchpad and palm rest are all protected with an antibacterial treatment8,9. This has been scientifically shown by the internationally recognized ISO 22196 standard to inhibit bacteria growth by more than 99% over a 24-hour period. ASUS Antibacterial Guard is also made to withstand alcohol-based cleaning products and hypochlorous acid water10, so the surface of your laptop stays clean and sanitary — limiting the spread of harmful bacteria.
ERGOLIFT HINGE
ExpertBook B3 Detachable is engineered to make the typing experience more comfortable and more accurate. The ErgoLift hinge automatically tilts the keyboard to the most comfortable typing position. It also has widely spaced, long-travel keys that provide responsive tactile feedback for more accurate typing.
SPILL-RESISTANT KEYBOARD
Accidents happen, and the ExpertBoard is ready for them: the spill-resistant keyboard11 can cope with up to 60 cc of liquids without harm12, so minor spillages on the keys can be easily drained, cleaned and dried.
VISION-PROTECTING DISPLAY
ExpertBook B3 Detachable features a 16∶10, multitouch screen that provides intuitive input for modern learning and working experiences. TÜV Rheinland has certified the panel as having low blue-light emissions, which helps to protect eyes from potential harm.
MILITARY GRADE
Military-grade toughness and build quality
Life on the road is tough, so ExpertBook B3 Detachable is designed to both meet and surpass exacting industry thresholds — including the ultra-demanding MIL-STD 810H U.S. military standard. It’s built to survive every extreme, from freezing temperatures to the searing heat of deserts, and high-speed shocks to everyday bumps. B3 Detachable also undergoes stringent in-house testing, including panel-pressure, shock and drop tests for an assurance of serious durability13.
