Zenbook

Asus Zenbook is a line of notebook computers produced by Asus. The first Zenbooks were released in October 2011 as Ultrabooks, and the original range of products has since been expanded to models ranging from smaller and power efficient notebooks to high-end and larger laptops with additions like discrete graphics processing units. As of 2024, the Asus Zenbook S serves as the company's flagship notebook computer.

Asus designed the Zenbooks with brushed aluminium chassis and high rigidity, rather than plastic, the usual laptop construction material. A pattern of concentric circles on the lids is said to represent ripples in water and represent the "zen philosophy" that designers wanted to portray when creating the laptops. As of 2024 there are various series including the standard Zenbook, extra slim and light Zenbook S, performance-oriented Zenbook Pro with dedicated graphics cards, convertible Zenbook Flip, dual screen Zenbook Duo and foldable tablet Zenbook Fold.

Asus made a material they call Ceraluminum (from ceramic and aluminium) for the exterior of their Zenbook laptops.
