Crafted to perfection
The magnesium‑lithium alloy used in the latest ExpertBook B9 is durable yet lightweight, resulting in a laptop that's 16% lighter than the previous model3. The chassis is methodically-crafted, undergoing a complex 21 stage process to create its tough, but exquisite, exterior.

CNC-milled for strength
To create the precision-cut lid and complex keyboard surround of ExpertBook B9, a high-precision CNC-milling process is used to shape single pieces of solid metal. This reduces unnecessary internal voids, helping make the entire chassis tougher and stronger than is possible using traditional metal-stamping methods.
First impressions count
Taking inspiration from the concrete jungle, ExpertBook B9 incorporates architectural elements into product design. From its precisely-shaped corners and edges to its sleek finish, ExpertBook B9 makes a lasting first impression.
Speed is of the essence
A high-performance PCIe 3.0 x4 SSD gives ExpertBook B9 the fastest storage available so you'll never be kept waiting for the OS to boot or for applications to load. And because they don't have any moving parts, SSDs are also incredibly reliable and quiet.

Panel Self Refresh technology
Panel Self Refresh technology relies on dedicated memory built into the LCD display panel itself. It's used when the display is showing a static image, and saves energy by shutting down the video processor and its circuitry. This lower power consumption allows a much longer battery life.
Mobility without bounds
Apart from the cutting-edge dual-band Wi-Fi 6 (802.11ax) — up to 3x as fast as Wi-Fi 5 (802.11ac)7, ExpertBook B9 incorporates ASUS Wi-Fi Master technology, so you'll enjoy faster and more reliable Wi-Fi connections at greater distances than ever before. Combined with the latest Bluetooth® 5.0 that lets you connect your favorite devices with less impact on battery life, ExpertBook B9 gives you the freedom to do whatever you need, wherever you want to!
