Asus VivoBook E403SA-US21 14″ Thin & Light Laptop (Intel Pentium Quad Core, 4GB RAM, 128GB eMMC, Win 10)


The Asus VivoBook E403SA-US21 is a 14″ thin-and-light laptop, which delivers premium look and feel at an affordable price of around $400.

Besides slim design of its 0.7″ thin aluminum-topped chassis, the 3.3-pound VivoBook E403SA-US21 offers crispy Full HD display resolution as one of its best selling points. In addition, this Windows 10-based laptop features a massive 57 WHr battery, which is very large for this type of a laptop. Asus claims the E403SA-US21 has an “all-day” battery life of up to 14 hours.

The rest of the specifications sheet isn’t as impressive, since only lower-mid-range internal components are included. Also, some perks like touchscreen, IPS wide viewing angles technology, or keyboard backlight are missing.

The heart of the system is the Intel Pentium N3700 processor. It’s a power-saving quad-core chip which can’t beat the popular dual-core Intel Core U-series CPUs, despite having four cores instead of two. Nevertheless, the Pentium N3700 with its Intel HD integrated graphics is serviceable when it comes to the daily routine home and office PC chores, as well as some very basic gaming. 4GB of RAM is a decent size, but it doesn’t follow the 8GB trend in the mainstream laptop category and isn’t enough for heavier multitaskers. For storage the notebook uses a 128-Gigabyte eMMC instead of slower hard drive storage. eMMC, however, isn’t as fast as solid state drive-based storage and sits somewhere between HDDs and SSDs on the performance scale. Of course, any hard drive-equipped laptop offers multiple times greater data storage space, starting at 500GB.

When it comes to the latest technologies incorporated in this laptop, use of the new USB-C type port is the only noticeable feature. Besides a single USB-C, the machine includes a non-surprising set of features including a USB 3.0 and a USB 2.0 port, HDMI video and mic / headphone audio ports, a media card reader, 802.11AC wireless Internet connection, and Bluetooth interface.

  1. Charmaine Cheng – August 22, 2016:

    Hi there — thinking about buying this laptop for drafting on AutoCAD and Revit, do you think this laptop will be suitable? As well, will I be able to up the RAM if needed? Thanks!


    • Danijel Z – August 22, 2016:

      The Pentium CPU in this laptop is typically used for routine home and office tasks, not engineering software and such. The Intel Core i-series processors are more suitable for AutoCAD and similar more demanding programs (quad-core Intel Core i7 are the best for the purpose). But they’re more expensive… If you have a limited budget, I advise you to take a look a this HP 14″ model: http://laptoping.com/specs/product/hp-14-an013nr-14-inch-notebook-amd-e2-4gb-ram-32-gb-hard-drive-emmc/
      It has a much better screen, upgradeable RAM as opposed to soldered on the Asus E403SA, and faster processor (although not in the same class as the Intel Core CPUs). The limitation of the HP is small storage space, so if you plan to install both AutoCAD and Revit (and nothing else), you’ll be left with only a few Gigabytes or even without free storage space. And you’ll probably have to install the programs from a separate storage like USB or memory card.

      On the other hand, the Asus will be able to run CAD and Revit since it meets their hardware requirements, but not so snappy and maybe with occasional slowdowns.
