Product Description

ASUS VivoBook 15 K505ZA Laptop

Thinner and lighter

ASUS VivoBook 15 is thinner and lighter than ever - with an amazingly thin 18.9mm profile, it weighs just 1.6kg*. It's an everyday laptop with the weight and compactness of an ultrabook.


NanoEdge display with ultra narrow bezel

The ultrathin bezel of the NanoEdge display on the VivoBook 15 allows a 15.6-inch Full HD display to fit into a frame size that's only slightly larger than those typically used in 14-inch laptops. The 7.7mm bezel on the NanoEdge display also results in an incredible 81% screen-to-body ratio - so you get more screen for more immersive viewing.


Amazing performance

ASUS VivoBook 15 is powered by up to the latest generation AMD Ryzen™ 7 processor with up to 16GB DDR4 RAM and AMD Radeon™ Vega¹⁰ processor graphics for smooth visuals and great gaming experiences. It also features dual-band 2x2 802.11ac Wi-Fi - so you'll enjoy super-fast online performance.


Complete connectivity, including USB Type-C™

A USB 3.1 port with a reversible USB Type-C™ connector makes connecting devices quick and easy. USB 3.1 provides data transfer speeds as fast as 5Gbps - up to 10X faster than USB 2.0 connections! Transfer photos, music and large video files in a fraction of the time. For example, a 2GB movie takes less than two seconds!
