Slip your ExpertBook B9 into a briefcase so itʹs with you all the time for productivity in and out of the office.
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
