ASUS presents the Vivo book 15 X1504ZA-NJ540WS as a light, thin, everyday-use laptop combining portability, modern performance and convenience. It’s designed to be your go-to machine for daily tasks — office work, browsing, media consumption, study/work from home, and general productivity — while being easy to carry around.

With the 12th-gen Intel Core i5-1235U CPU, 16 GB RAM, and 512 GB NVMe SSD, the laptop aims to deliver smooth multitasking, fast boot & app load times, and responsive everyday performance.

 The integrated Intel Iris Xe GPU lets you handle light-to-moderate graphic tasks (photo editing, casual games, video playback) — not heavy gaming or 3D work, but more than sufficient for normal uses.

The 15.6″ Full HD anti-glare display gives you a clear, sharp view for docs, movies, browsing — with a design optimized for comfort during extended use (with TÜV Rheinland-certified panel to reduce eye strain). Physically, the laptop is designed to be thin (≈ 17.9 mm thick) and light (~ 1.7 kg), making it fairly portable for a 15.6″ device — a plus if you carry it between home, office or college. Other convenience touches: a backlit chiclet keyboard, a privacy shutter for the webcam (good for video-calls & privacy), a lay-flat 180° hinge (good for collaboration or content sharing), and Wi-Fi 6E + modern connectivity for fast internet and seamless wireless use.
