The metal alloy material used to built the top and bottom chassis reeks of nothing but sturdiness, brilliant ergonomics, and premiumness. Also, the device was manufactured using up to 40 processes and is MIL-STD 810 G tested against extremes of temperature, humidity, shock etc.

One of the highlights of the laptop’s design is its hinge mechanism which ASUS calls the ‘ErgoLift’ hinge. When you pen the ZenBook S lid, the bottom chassis (or base) is tilted upward to about 5.5 degrees food improved airflow, audio quality, as well as overall typing experience. Perhaps due to the need to keep the ZenBook S as slim as possible, a couple of connectivity ports have been axed off. All the Asus ZenBook S comes with are USB-C ports and an audio jack. Interestingly, despite the lack of some vitl ports, Asus makes up for it by adding a couple of accessories out-of-the-box. USB-C to USB-A, USB-C to HDMI etc.


While there are three display configurations of the Asus ZenBook S, they all have the same 13.3-inch IPS panel display with slim bezels that are perhaps the narrowest you’d find on a 13-inch laptop. There are three different options to configure the ZenbZen S display.:

  • 13.3-inch touchscreen, matte FHD (1920 x 1080 pixels) resolution
  • 13.3 inch non-touch, glossy FHD (1920 x 1080 pixels) resolution
  • 13.3 inch touchscreen glossy UHD (3,840 x 2,160 pixels) resolution

Processor and Storage

The Asus ZenBook S will perform brilliantly with unruffled speed and fluidity as it uses Intel latest 8th generation Whiskey Lake hardware. It is available in Core i5-8250U and Core i7-8550U variants both of which are laced with Intel UHD 620 Graphics.

The Core i5 model of the ZenBook S comes with 8GB of RAM, 256GB SSD while the Core i7 counterpart sports 16GB RAM and 512GB SSD. The RAM, as well as the processor,  are soldered to the main board. This means that RAM cannot be replaced or expanded. The SSD, however, isn’t soldered and can be easily replaced, expanded, or both. Both versions of the ZenBook S run the Home Edition of the Microsoft Windows 10 operating system out-of-the-box.


The Asus ZenBook S has a 50Wh battery which, though won’t supply all-day battery life and usage, can last anywhere between 6 hours to 8 hours on in light usage, minimal brightness, and other factors. The battery is held by a screw and can be replaced and swapped easily.

  • Model 1: Intel Core i7-8550U CPU, 16GB RAM, a 512GB PCIe SSD, 13.3-inch 4K UHD display — ~$US 1,500.
