Asus U6S Review

by Reads (32,180)

The Asus U6S is a solid notebook that sports a 2.2GHz Intel Core 2 Duo processor and has a 12.1" LED backlit screen that saves on battery life. The glossy brown lid has blue accent flakes in the paint, which we like to call "flavor crystals" that really catch the eye. It performed quite well on the benchmarking tests as well, so let’s take a closer look to see how well it stacks against the competition.

Build and Design

The U6S has a unique design. As I mentioned above the lid has a nice glossy brown piano finish, with blue flakes, but that isn’t the only thing that catches your eye. It also has a shiny brown leather palm rest area and a black leather wrapped battery. The U6S sports that sophisticated look, while maintaining a consumer price tag.

The leather palm rest and battery help keep the notebook’s temperature cool. I didn’t have any problems with excessive heat even when I ran the benchmarking tests. The U6S is comfortable to hold and work on.

Weighing in at 3.5lbs and having the 12.1" LED backlit screen make this notebook great for traveling. It is lightweight and doesn’t take up much room in your bag. The chassis is solid and so is the hinge. I didn’t notice any signs of flex in the design, except on the keyboard, which we will discuss later.

The screen bezel and keyboard are silver, which make the brown color of the notebook pop. I also like that all the indicator lights were a purplish-white color. It is a nice change from all the blue LED indicator lights on most other notebooks. The U6S has a softer appeal, even the screen colors seem softer. If you like to chat with friends and family on the Web though, you are in luck because it does have a nice 0.3 mega-pixel webcam.


The 12.1" WXGA (1280 x 800) LED backlit screen is nice. The LED backlit option saves on battery life and makes the screen look very clear. It gets bright, but the colors are kind of washy. By this I mean the colors aren’t bold and vivid, they almost look kind of pastel.

The screen is easy on the eyes though and I had no problems reading any content from my favorite sites like It has good viewing angles, but I did notice toward the corners of the screen the color does fade out and it looks light, almost white in color. There is an HDMI port on the U6S, so if you want to hook up to a TV you can and the image quality is actually fairly good.


The keyboard is basic. It has the flat designed keys that are common on all Asus notebooks. Since the keys are flat, if you are a fast typer you have to be careful because your finger can get caught on one of the keys and pull it right off. I have had this happen on my Asus R1 tablet, which has the same keyboard design.

I do like that it has a silver color keyboard and the finish on the keys seem more durable then on my Asus R1. I didn’t notice any fingerprint grime.

The touchpad is dark brown, which coincides with the rest of the palm rest area. It has a textured look to it, but feels smooth. Thankfully there is a nice ring around the touchpad so you know where it stops. It is accurate and responsive just like a mouse, but I wasn’t a big fan of the right and left click buttons. They seemed to stick sometimes and weren’t as responsive.

Performance and Benchmarks

The U6S was impressive. I am used to reviewing Tablet PCs on a daily basis and was pleased with how peppy it was. The 2.2GHz Core 2 Duo processor was responsive and had no problems surfing the Web, checking email, running multiple applications or running benchmarks. I was disappointed in the 3DMark scores it ran though. I was expecting a little more out of it.

The U6S didn’t over work itself and booted up in no time. I did not test any games on the notebook because I am not a gamer, but since it has a good processor and decent graphics, I am sure it can play basic games.

wPrime is a program that forces the processor to do recursive mathematical calculations, the advantage of this program is that it is multi-threaded and can use both processor cores at once, thereby giving more accurate benchmarking measurements than Super Pi. (Lower numbers mean better performance.)

HDTune measures the storage performance of a PC:



I am pleased with the array of ports offered on the U6S. It has four USB ports and an HDMI port. Asus is very good at putting enough features on their notebooks to fit any users needs. That, and giving you nice accessories included with the notebook like a bag and mouse.

The U6S comes with the standard 802.11a/g type signals and the new draft N is optional. I had no problems connecting to secured and unsecured networks. Range was good compared to my R1 tablet; the U6S picked up networks my notebook didn’t even see. If you need better Internet connectivity options, you can always get 3G/3.5G Antenna support, which is optional.

It comes standard with integrated Bluetooth 2.0. I tested it out with one of my Logitech Bluetooth mice and it worked as expected. I had no problems connecting the mouse or using it. I actually liked it better then the touchpad.


The speakers on the U6S were surprising. I was expecting a little more I guess since it’s a notebook. Not that they didn’t sound good, but they weren’t something I would jam to my iTunes with. The sound was clear and it did get loud, just nothing in the entertainment realm. Much better then any tablet I have reviewed though, except for the HP tx2000. The microphone and headphone worked great though. I used the headphone port to drown out office noise when I was busy.

Heat and Noise

Heat, what heat? That is right, the U6S never got hot, in fact it barely got warm. It was nice to work with and comfortable. I could set it on my lap and not be worried about anything. The leather may have helped or just the fact that it vented well. Compared to many other notebooks, the U6S is definitely one of the coolest. The temperature readings were even taken after running the benchmarks and the computer being on for a few hours.

The U6S was quiet as well. That is, once I figured out how to adjust the volume. When you turn it on it makes a loud annoying startup chime during boot-up. I hardly noticed the fan running and even when playing a DVD, the optical drive wasn’t that loud. It might bother your neighbor in a library, but not in an office environment.


The standard battery that comes with the U6S is a 3-cell battery. I definitely recommend getting the 6-cell because the 3-cell battery doesn’t give you enough power to write a mid-term. After being completely charged, the 3-cell battery that came with the U6S died in less then two hours and it wasn’t even set to the High Performance mode.

The 6-cell battery doesn’t sit flush with the back of the notebook, but provides much better battery life. At least you can unplug your notebook and not worry about it crashing in an hour. I got about three to four hours of battery life with the 6-cell battery depending on if I was in Power saver mode, Entertainment mode or High Performance.

OS and Software

Windows Vista Business comes standard on the U6S. I didn’t see any other options on their website, but I am sure you can change this depending on where you purchase the notebook. I had no problems with Vista Business though. There wasn’t much if any bloatware either, which is a bonus. I didn’t have any problems entering/resuming from standby, and hibernation worked fine as well. Beware though it seems the standard battery dies quick and likes to put you in hibernation mode often, so this may be something you reset in the Control Panel.


The U6S has a sharp design. It is sleek, lightweight and great to travel with. If you do travel a lot make sure you get the bigger battery though because the standard battery will have you plugged in to the wall all the time. The LED backlit screen is soft on the eyes and easy to read. The leather palm rest is comfortable and a nice touch of flare. The U6S maintains that sophisticated look, but with a knock-off price tag, which we like. It isn’t a rugged notebook by any means, but has a solid chassis and can take a few bumps and bruises of your daily grind. Overall, I was impressed and would recommend it for anyone looking for a notebook for work or school. It’s not to expensive and has great features.


  • Good variety of ports, including HDMI
  • Appealing design and color
  • Solid chassis
  • LED backlit screen, preserves battery life
  • Doesn’t get hot and has nice leather palm rest
  • Included accessories


  • 3-cell battery has bad life, need 6-cell or bigger
  • Keyboard shows signs of flex
  • LED screen is light in color not vivid or bright
  • Right click button on touchpad sticks
