Lighter, stronger, and more portable

Get the job done, effortlessly
No task is too great for the ultracompact ExpertBook B9: it helps you get work done as quickly and efficiently as possible. Itʹs powered by up to 11th gen Intel® Core™ i7 processor with Iris Xe graphics and superfast intel WiFi 6, providing quick and responsive computing, network and graphical performance. It also features two SSDs to provide huge up to dual 2 TB capacity and faster speed, and supports RAID technology for improved data reliability or faster operation.

Lasts longer, charges faster
ExpertBook B9 will never let you down throughout the business day or a long-haul flight. It provides all-day battery life on a single charge, aided by energy-efficient Panel Self Refresh technology. On top of that, fast-charge technology lets you recharge the battery to up to 60% capacity in as little as 39 minutes6, so you’re up and running in no time.

Comprehensive connectivity with no compromise
Despite its thin profile, ExpertBook B9 is loaded with I/O ports. These include cutting-edge Thunderbolt™ 4, the next generation of the universal cable connectivity solution that offers support for the next-level USB 4 interface, 40 Gbps data transfer speeds, dual 4K display output and fast charging. Aside from the standard USB Type-A and HDMI output, it provides wired network connectivity with a unique MAC address for easy device management.

Military-grade toughness and build quality
To be strong enough for all your travels, ExpertBook B9 is solidly built with magnesium-lithium alloy and structural reinforcement for increased chassis strength. It meets next-level and industry-leading MIL-STD 810H US military tests, which is more rigorous and demanding than ever before. It also undergoes stringent in-house testing including panel-pressure, shock and drop tests to ensure durability, so there’s no need to worry about everyday knocks and bumps.

Next-level AI noise-canceling audio technology
With the increase of remote work and video conferences, we implemented the ASUS AI noise-canceling technology to ensure the best experience. ASUS AI noise-canceling audio employs machine learning in order to isolate unwanted noise from human speech. The ClearVoice Mic feature in the MyASUS app can filter out ambient noise, and normalize all individual voices in Multi-presenter mode from different positions for optimum group conference-call quality. The ClearVoice Speaker feature filters out all ambient noise apart from human speech — so you’ll hear what everyone else is saying. Try the demo to experience the amazing difference in different environment that ASUS AI noise-canceling technology can make.

Immersive audio
ExpertBook B9 assures you top-notch audio, thanks to four omnidirectional far-field microphones, smart amplifier technology, and Harman Kardon-certified speakers. The microphones on the upper bezel of the display capture voice clearly. The ASUS Golden Ear team worked with renowned audio experts Harman Kardon to ensure ExpertBook B9 provides true surround-sound cinema-quality audio.

Get to work faster with AdaptiveLock
With its smart proximity sensor ExpertBook B9 doesn’t keep you waiting. The moment you sit ASUS AdaptiveLock detects your presence and uses an integrated infrared camera to recognize your face and log you in — allowing you to get to work without lifting a finger. Then, when you step away, ExpertBook B9 automatically locks itself, protecting both your laptop and your data.
