The Asus X551CA-SI30403X is one of the inexpensive laptops for everyday home use. It sports a 15.6-inch screen with mediocre 1366-by-768 resolution and a full-size keyboard with numeric pad but no backlight. The processor is the 3rd Gen (2012) Intel Core i3-3217U with sufficient power for routine computing, such as web surf, document editing, multimedia playback, and some basic games such as Minecraft. It’s way better in terms of performance than the commonly used Intel Pentiums and Celerons in the budget laptops. 4GB of RAM is included, which is enough for the aforementioned tasks and for running them simultaneously. Hard drive capacity is 500GB which is also mediocre specs point, but quite satisfactory for the “run of the mill” users. DVD burner is present, as well as stereo speakers, webcam, HDMI video out and VGA video out, and a media card reader. USB port count is only two, instead of the usual three.

The chassis sports black matte finish with a textured anti-slip feel to it. It is 1.2″ thin and weighs 4.7 pounds. It’s pretty much light weight for the category the Asus X551CA-SI30403X belongs to.

If you generally like this laptop but the price is to high for you, you can check out this model. It has a slower processor, but costs only $250.

    Hello, may Iask if I can replace/upgrade the RAM on this model please ? Is the RAM soldered onto the logic board or is it a physical slot ? Please help me with this!

    • Danijel Z

      Not sure about this particular model, but the X551 Asus series usually have 4GB of RAM soldered onto the motherboard and a single user-accessible RAM slot for RAM expansion. Big chances are your model has the same RAM setup.

    Intro: I bought this laptop in summer 2014 in Bestbuy. Good looking, Sound is perfect.

    BUT:
    1. It works slowly ‘ cause of Windows8.
    2. The material of the Notebook is not so good. It’s so thin and can easily curve.
    3. Cover of keyboard is a little deformated, it’s slightly arched.

    Conclusion: I think, there are many monkeys work in Asus factory in China.
