ASUS S56C 15.6-inch Ultrabook Review

by Rob Williams on March 1, 2013 in Systems

The “Ultrabook” term is often associated with super-small notebooks, but ASUS is here with a model to remind us that 15.6-inch models can be included, too. We’re taking a look at the S56C, a Core i5-3317U-powered offering that includes 6GB of memory, a 24GB SSD for caching, and is built like a tank.

Final Thoughts

Like our look at ASUS’ X202E, I didn’t plan on doing too much benchmarking here. The simple fact is, while the S56C does have a nice (for the price-range) CPU, this not going to be a notebook used by those who need performance. Expect to use it for “normal” tasks, like Web-surfing, editing documents and images, watching movies and so forth.

Gaming-wise, much like the X202E, don’t expect to do too much. Current block-busters are out of the question unless one happens to be real modest. Browser-based games and most aged games run with little issue, but just don’t be surprised if you need to decrease the graphical detail. For any sort of gaming on the go, I’d never choose to do it on an integrated GPU.

In normal use, I found the S56C to be a bit snappier than the X202E. Part of the reason could be the Turbo-enabled CPU, but it could also have to do with the slightly-faster DDR3 memory (DDR3-1600 versus DDR3-1300). There is also the fact that this notebook includes a 24GB SSD for caching, although it’s hard to say with certainty if that was the lone benefit, because the notebook felt quite responsive right from the beginning.

Like the X202E, I could playback good bit-rate (20Mbit/s) 1080p content without issue, so while not a power-house, the S56C still delivers what most people should be looking for. This is a ~$630 Core i5 15.6″ notebook, after all.

Features-wise, while I found it painful to have no touchscreen (what on earth has happened to me?), it delivers on most fronts. It sports an optical drive, USB 3.0 (though more than one port would have been preferred), a 720p webcam, an easy-to-type-on keyboard, a touchpad that’s easy to use for many hours on end and SSD caching – a perk we don’t see too often.

One area where I found the S56C fell a little flat was with the audio. I knew from the get-go that the notebook included “SonicMaster” audio (ASUS’ own technology) like the X202E did, but I couldn’t figure out why it didn’t have quite as much punch and clarity. As it turns out, the solution here is actually called “SonicMaster Lite”. The audio is not bad by any stretch, but after hearing what the X202E was capable of, I guess I’ve become spoiled.

On the battery-life front, the S56C dipped below an unimpressive 2 hours for entertainment use, but it delivered an acceptable 4h 20m in our productivity test. Not the most impressive battery-life around, but it’s hard to expect much more for this price-point.

Speaking of pricing, at $630~$660, the S56C is spec’d quite well. While it’s impossible to compare all notebooks out there, I hit up the most popular locations to see what else was out there. The most comparable offering I could find was Lenovo’s U510, at $699. It boosts the CPU to a Core i7-3517U and the RAM to 8GB, and aside from that, the specs align extremely well.

The most equivalent model from Dell, Inspiron 15z, costs $699. It has a weaker processor, no SSD for caching, and a smaller hard drive (500GB versus 750GB). It’s not exactly an attractive model specs-wise compared to either this ASUS or the Lenovo.

Priced at $630, ASUS’ notebook looks to have the better value-to-dollar ratio over the Lenovo, but at $660, that gap shortens to the point where both notebooks are even. At that point, it depends on whether or not you feel $40 or $70 is worth it for the processor upgrade and extra 2GB of RAM (ignoring the fact that the design of the notebook is different).

On this sort of notebook, I’m inclined to believe that it wouldn’t be worth the extra cost for most people. As mentioned earlier, while these dual-cores are capable, they are not meant to be workhorses – and thus, who will use them as such (aka: who will actually use the entire 6GB, much less 8GB, or notice a 200MHz boost on the CPU)? If the delta was more like $20, the decision would be easier to make.

That said, ASUS delivers a great offering here for the price. If you’re in the market for a larger notebook that won’t break the bank, it should definitely rank up high on your considerations list.


  • Good dual-core processor, abundance of RAM.
  • Handles 1080p high-bitrate (<20Mbit/s) content like a breeze.
  • Great touchpad and keyboard.
  • Built like a tank.
  • Decent battery-life.
  • Priced right ($630~$660).


  • Realistic gaming is out.
  • An Ethernet jack towards the front of the notebook?
  • Audio system is not quite as good as what we saw on the X202E.
  • Sometimes it is really easy to swipe the touchpad so that it brings up the Start screen or Charms bar.
  • McAfee bundleware needs to die.

    When it works it works great but mine initially had sudden shut downs for no apparent reason. Help line and dealing with Best Buy was a disaster as they never resolved the problem. Neither seemed to care. Luckily it stopped doing this after a few months. ASUS used to be a great company but salespeople tell me this has changed a lot in last 18 months. Too bad I bought it based on the still good reviews. It is light and travelled with it all over Europe in backpack and never felt its presence. Did lose wifi for no reason but refreshing Win8 did the trick. Unfortunately installing any kind of new software seems to create havoc and another refresh of Win8. Maybe it is more the os than the computer causing problems? Anyway next time I will do the unthinkable – get an extended warranty.

      From what I’ve seen with ASUS Transformer related forums, a lot of the issues suddenly pop up during Windows updates. A friend of mine had their Transformer almost bricked after an update; it was caught in a perpetual boot-loop. Fortunately, there’s restore options and such, but the fact remains there is something off with the updates and the hardware. Blame could go either way, so it’s not safe to point fingers. While that was a Transformer, and this is an Ultrabook, the problems might be transferable and related.

      What might be wise is to set Windows update to manual, then update a week or two after patches are released. The other thing might be to see about what ASUS based software can be safely disabled, as those extra power management services might be interfering. One final thing is to check the memory integrity – bad RAM can cause all kinds of funky problems.

        Thanks Jamie for those insightful comments.

        You probably are way closer to true solutions. I think that you are unto something huge especially when you talk about ” something off with the updates and the hardware ” as possibly being at the source of my problems. I have refused so far to upgrade to Windows 8.1 from fear of more problems (Heard of loss of wifi etc). But since the release was months ago maybe I should consider it now though I read the differences are not that noticeable to the regular user (Start up button not an issue for me).

        I have wondered about the use of some of these ASUS software programs. RAM sure could be another one. I am going to look into your suggestions.

        Anyway thanks for the reply.

        So here I was in Portugal with the ASUS S56C for the winter staying away from a brutally cold winter back home when out of nowhere it shut down for no reason. Hmmm this had not happened in about 6 months and not since (fingers crossed). I had been putting off updating to WIN 8.1 for almost a year but finally it went ahead and updated itself without my permission. Turns out every thing works fine and even seems a bit faster processing stuff. Still enjoying it in year three and when I see the price of decent puters these days I am glad I only paid $549CDN.

          So… it could have been the OS at fault, not the hardware? Either way, glad the issue hasn’t been plaguing you since the update!

    I have been using the S56C for a year and a half now, its just amazing. Previously I was using an HP gaming series laptop, it put me off everytime i switched it on. Asus is awesome, its ice cool technology and the 2 sec instant on and good speed performance, and I also manage to play some good graphics games like Crisis, NFS hotpursuit 2 etc… so beautifully crafted into a mere 21mm chassis. Lovely one from Asus.

    what is the weight of it?

    I am using this laptop (Asus S56C) since 2 years, I love it, its simply awesome. I bought this laptop after careful study, I did lot of research on laptops, saw rankings of most reliable laptop brands and found out that Asus is the best. This laptop is very reliable and efficient. Its quite light and sleek. The only thing it lacks is high color resolution. Its screen doesn’t give great graphics or hd colors, but the rest of the features are simply great including sound, camera, keyboard with number pad, mousepad etc, battery life is great too after 2 years the battery of this laptop still runs for 3 hours atleast.

      I’m glad to hear the notebook has treated you so well!
