ASUS Zenbook UX390UA

The ASUS Zenbook UX390UA is a part of the third series of ASUS Zenbooks, which was released in 2016. It was updated with the "Deluxe" edition only a year later, and was discontinued in 2019. The product was sold in multiple regions of the world, but differed in models across those countries.

This device is known for its thin appearance and quick performance. The intended demographic that ASUS wanted to satisfy was the traveling professionals. Since the laptop is sleek and portable, it is meant to be easy to use anywhere. The UX390UA has a 12.5 inch display and utilizes 16 GB of RAM and Intel Core i7 processors.

This Zenbook was replaced with better Intel Processors after a few years, but this model was the beginning of a shift within the company. Another brand came out with the Macbook at the time, so it pushed ASUS to continue creating faster and more adaptable laptops.

Although the design has praise for some of its features, there were some consistent failures with the laptop, which is why it was updated. The battery only lasted a few years, which led to the device not being able to hold a charge. The USB port, which is responsible for charging and any other connections, also had many reports of issues.

This laptop has a spun metal finish made of grade-6013 aluminum alloy for a light but strong exterior. The UX390UA came in the color waves of royal blue, rose gold, and quartz grey, with every model having a gold ASUS logo and gold backlit keyboard. The dimensions of this device are 11.65 x 7.51 x 0.46 inches. The laptop weighs around 2 pounds and has a display screen of 12.5 inches. You can find the model number of the laptop on a sticker on the bottom of the device.
