Design and Build

The chassis uses a magnesium-lithium alloy, which helps keep the notebook both light and rigid. The review describes solid build quality with no major flex despite the thin profile. The laptop opens up to 180 degrees, and the ErgoLift hinge slightly raises the keyboard when the lid is opened, which can improve typing angle and airflow. The matte dark-blue finish is also practical for office use because it resists visible fingerprints better than glossy surfaces.

Display, Audio, and Webcam

The 14-inch Full HD IPS panel has a matte surface and a stated brightness level of 400 nits. In practice, this is suitable for indoor work, while strong direct sunlight can still be challenging. The source notes good contrast and full sRGB coverage, which is useful for users who occasionally edit photos or video at a non-professional level. Stereo speakers tuned with Harman/Kardon are clear for calls and media, though bass remains limited. The 720p IR webcam supports Windows Hello face login and includes a physical privacy shutter.

Keyboard and Touchpad

The keyboard is spill-resistant, backlit, and comfortable for long typing sessions, with clearly sized keys for frequent actions. A practical warning from the source review: the power button sits close to the Delete key and has a similar size, so accidental presses are possible until you adapt. The touchpad is large, responsive, and includes an integrated NumberPad function for fast numeric entry. A separate fingerprint scanner is placed near the touchpad for quick authentication.

Performance, Ports, and Battery

With Intel Core i7-1165G7 and Iris Xe Graphics, the ExpertBook B9400 is positioned for office workloads such as browser multitasking, documents, spreadsheets, video meetings, and general productivity. The reviewed 16 GB RAM and 1 TB SSD setup supports smooth day-to-day business use. Wired connectivity includes two Thunderbolt 4/USB-C ports, USB 3.2, HDMI, Micro-HDMI (for LAN adapter usage), and a combo audio jack, with Wi-Fi 6 and Bluetooth 5.0 handling wireless tasks. Battery capacity is 66 Wh, and the source reports around 16 hours in light office scenarios and about 9 hours of online video playback, with fast charging up to 60% in approximately 40 minutes.

Verdict

The ASUS ExpertBook B9400 is best suited to mobile professionals who prioritize low weight, reliable business performance, and strong security basics. Its main strengths are portability, practical port selection, and long battery life in office-style usage. The main compromises are modest webcam clarity and limited bass from the speakers. Overall, this configuration presents a focused business tool rather than a multimedia or heavy creative workstation.
