Review: ASUS VivoBook S400CA (Internal & Upgrades)
In my earlier post, I have discussed the design and specifications of the new ASUS VivoBook S400. Now, we will be looking at a slightly more technical aspect of the S400. The base of the ASUS VivoBook S400 is secured by 10 screws and plastic clips around the border of the chassis.
Upon removal of the screws and unlocking the plastic clips, you will be able to have a full view of the components of the ASUS VivoBook S400.
The bottom portion is the internal polymer battery that can be easily replaced should the lifespan of the battery be over. The capacity of the battery is 44 Whrs. On my first full charge, I am able to use the S400 for approximately 4 hours, with screen brightness set at 50% and WIFI turned on and working on Microsoft Word. It is considered pretty close to the advertised battery use of up to 5 hours. I guess you should be able to squeeze more juice out of the battery if you were to decrease the brightness of the screen.
Let us now zoom in to the more common upgrades that you may wish to do. As you can see from the image below, the additional memory slot is empty. I suspect that the onboard 4GB DDR3 SO-DIMM ram is below the keyboard. However, I did not pry open as I still need the warranty for this unit. You can simply pop in a 8GB DDR3 SO-DIMM 1600MHz ram to boost the total memory to 12GB. The black cover above the ram slot is the mSATA slot that is used by the SanDisk 24GB mSATA SSD.
The ASUS VivoBook S400 is using the conventional disk-spinning HDD which you may want to consider replacing with a solid-state drive (SSD). You just need to replace the 4 black screws at the side, and the HDD can be slide out easily without much effort. As SSD does not have any rotating parts, it is more durable for use on the move. It also draws lesser power and has a much higher read/write speed. However, do take note that the HDD used in the S400 is 7mm. Thus, you have to get an SSD that is 7mm. These are some of the 7mm SSD that I have found: Crucial M4 D1 Model, Plextor M5 Pro and Silicon Power V70.
In case you are interested to replace the HDD with a higher capacity or RPM, the S400 is using the Seagate Momentus Thin.
That’s the end of my review of the ASUS VivoBook S400!
