Asus Zenbook UX31E review – this could be the best ultrabook, but…
Posted by: Andrei Girbea | Last updated on: 15 Dec 2011 | See the comments
Summary: With a stylish and solid built body, the Zenbook is on of the best looking ultrabooks on the market. It's also very fast, however the screen and the keyboard did not live to our expectations, but overall the Asus UX31 is one of the best 13.3 inch ultrabooks out there right now.
Rating: 4 / 5   Price range: $999 - $1499

THE GOOD

good looking and solid built, good HD display, excellent speakers, solid performances, proper price tag

THE BAD

shallow and imprecise keyboard, jumpy trackpad (partially fixed on the newer models), a bit too ostentatious for my taste

WHERE TO BUY:

After thoroughly reviewing the Lenovo U300s and the Acer Aspire S3, it’s now time to focus on the Asus Zenbook UX31, the ultrabook that seemed to have the best odds to be a real competitor for the MacBook Air a while back.

The Zenbook UX31 has been available for a while and I think now is the best time to see how good of a job Asus has done with their first ever 13.3-inch ultrabook.

Update: You should also check out this review of the Asus Zenbook Prime UX31A, which is this laptop’s direct successor. And this list of places to buy it discounted might be of some interest as well.

We are going to look at all the details a technology enthusiast might be interested in before buying the UX31 (or any other laptop, for that matter) and I’m going to try to find out if the 13-incher from Asus is nothing more than a cheap Air copy or if it is a strong and capable notebook with a personality of its own.

The complete Asus Zenbook UX31 review is available bellow, but you’ll also find my video review. If you’re not here for the whole story though, here’s a quick spoiler: the Asus Zenbook UX31 is good, very good actually, but because of some hick-ups, it’s second in my list of favorite ultrabooks.

The biggest hick-up is the keyboard, which for me is a crucial element, as I spend so much time writing articles, but there are some others. On the other hand, in terms of performances, looks and build quality, this is for sure top notch.

More in the paragraphs bellow though.

Video Review

Design and body

When I first laid my eyes on the UX31 a few months ago, I couldn’t shake up the feeling that I had seen a similar shape before. 

Of course , I wasn’t wrong, design wise, the UX31 is a close replica of the MBA; both are a bit thicker towards the back and get slimmer on their front and both come with full-metal casings.

On the other hand, you can’t say that the Zenbook UX31 is a bad or cheap copy of the MacBook Air, managing to borrow the good parts from Apple’s design and add some original spices here and there. The unibody case is the same as on the Air, the sturdiness and elegance are all there, but the concentric circles on the aluminum lid and the slightly darker shade of metal are original touches that make the UX31 stand on its own.

Of course, the Asus is a bit ostentatious, at least for my taste, but I’m sure many will just love the looks and the overall sturdiness and quality of the body (I appreciate the latter as well).

Opening the lid, you get a nice aluminum finish on the palm rest and the bezel around the screen, which add to the overall high-quality feeling exhaled by the Zenbook UX31.

The Asus UX31 is extremely light and thin, no matter how you look at it.

The Asus UX31 is extremely light and thin, no matter how you look at it.

As for the size and weight, the UX31 is doing just fine, weighing in at just 2.9 pounds (1.3 kg) and measuring a mere 0.67 inches in thickness.

There’s also a smaller and lighter version available if you won’t find the UX31 portable enough, the 11.6 inch Asus UX21, which weighs just 2.4 pounds.

Speaking of ports and connectivity options, the Asus UX31 trails some of its competitors. You do get USB 3.0 and 2.0 slots, but you don’t get an Ethernet port or regular sized HDMI on the machine. Instead, you get micro-HDMI and mini-VGA slots, plus two included adapters: one for miniVGA to regular VGA and one for USB to Ethernet. So overall, it’s not that bad, except that you don’t get an easy way to output digital video content, as you’ll have to buy an HDMI adapter on your own and the laptop does not support Intel’s WiDi (Wireless Display) either.

Keyboard and touchpad

For me, the keybord and trackpad combo is pretty much crucial when choosing a laptop. Unfortunately, these are pretty much strike and miss on the UX31.

Aesthetically, they both look great. The keys are proper sized and proper spaced, the trackpad is big enough and positioned where it should be. When you get to use them though…

First, the keys are wobbly and stiff, plus offer little travel, and unless you make sure you press them firmly in their middle, they might not register your hit. In time you’ll get used to the keyboard and  learn to make it usable, but that’s not how things should work on a computer in this price-range. Except for that, there’s little flex and the keys feel good to touch; too bad though such aspects don’t really matter when the typing experience is just bad.

The keyboard and especially the touchpad are surprisingly poor on the UX31.

The keyboard and especially the touchpad are surprisingly poor on the UX31.

The touchpad is even worse, suffering from ‘’chronic’’ software glitches and a severe lack of responsiveness from time to time. What’s weird is that the problems come and go and the trackpad will sometimes act accurate, comfortable and precise, while in other cases will simply go berserk and leave you asking why the heck didn’t Asus take its time with solving these issues before releasing the laptop.

These are drivers related problems and Asus promises to work on getting them fixed.

Update: Asus seems to have fixed most of the touchpad issues on their newer models that now pack an Elan trackpad (as opposed to a Sentelic one before). It’s still not perfect, but it’s way more accurate and reliable, so if you want to get an UX31, look for one with an Elan trackpad, or regret it forever.

Screen

The 13.3-inch screen on the Asus UX31 is in fact right now (as I’m typing this review in late 2011) the only one on an ultrabook to sport HD resolution, 1600 x 900 pixels. Yes, with Windows 7 everything will get a bit smaller (so if you have bad eyes, that might not be for you), but you also get this vastly increased canvas that greatly helps you improve your productivity.

The colors are crisp and this screen is probably the brightest you’ll get on an ultrabook these days. And while it comes with a glossy finish and the viewing angles could definitely be better (they’re not that bad though), I’d say the overall image quality on this UX31 is superior to everything we’ve seen so far on ultrabooks.

The bright high-res screen almost makes you forget about the glitchy touchpad.

Hardware and performances

In terms of hardware, the UX31  is available in a bunch of different hardware configurations, with the basic version being pretty much on par with the ones offered by most other producers in this class.

So, you get the Intel Core i5-2467M processor, as well as 4 GB of RAM, integrated Intel HD 3000 graphics and a 128 GB SSD. However, we’re talking about a SATA 3 compatible SSD, while most other ultrabooks only offer slower SATA 2 Storage.

The top model features a very snappy Intel Core i7 processor and a larger 256 GB SSD (which by the way, comes partitioned by default).

Overall, even the standard UX31 configuration should be enough for most ultrabook potential buyers, being able to handle multitasking and HD content playing. Games are a no-go, but that’s the same for all ultrabooks these days, as they come with integrated graphics; also, heavy-duty tasks like editing RAW photos and videos might push the low-voltage CPU towards its limits. For everyday stuff though, the UX31 is just fine and definitely snappier than the average laptop out there, thanks to the powerful hardware and that fast SSD.

Under the hood, the UX31 is the snappiest ultrabook today.

Battery life

There’s a 4 Cell 40 Wh battery inside this Zenbook and that’s enough to push the whole package for about 5.5 hours of daily use. Yes, Asus claims it can go for much longer and you can probably squeeze up to 7 hours of life for very very light usage (just reading some content with the screen dimmed down and no wireless). But not more.

For the everyday routine though, expect a little above 5 hours of life every charge, which is actually quite good, though not really better than the competition.

If only Asus had managed to fit in a full-sized HDMI port...

Noise, heat, speakers and others

The Zenbook manages to stay cool and mostly silent no matter how hard you’ll push it. The metal body seems to do an excellent job at dissipating heat and while the bottom will get warm, it will never pass beyond the “comfortable” point. Personally, I’m quite impressed with this, especially since before reviewing the UX31 I got to play with the UX21 and that one had some massive overheating problems (squeezing the same hardware in tinnier body was the issue there).

The speakers are actually quite good on the UX31.  The Zenbook features stereo speakers powered by Bang & Olufsen’s ICEPower and Asus’s SonicMaster technologies and the overall audio quality, as well as the volume, are pretty unbelievable for a laptop this small. So hands-down these are the best speakers on an portable laptop, even though when turning the volume up, the speakers (which are placed beneath the keyboard) might cause the keys to vibrate a bit (and hence you get some distortions). As long as you keep the volume bellow 75% though, these are just top notch.

On the other hand, the 0.3 MPx webcam is clearly not the best we’ve seen on an ultrabook today and can’t keep up with the competition. But will do the job, and that’s all I want from a webcam.

Pricing and availability

The UX31 starts at around 1100 dollars these days and can go to up to 1500 bucks or more, based on configuration.

Bottom point, the Zenbook UX31 is more expensive than most other ultrabooks out there and at least for the moment, only the Lenovo U300S out-costs it by $100.

Quality comes with a price though, as with the Lenovo, so if you want the extra goodies you get on this machine, you’ll have to pay a bit extra. In the end though, the 13.3 inch Asus laptop is still $200 cheaper than a similar equipped MacBook Air, thus given all the features, its price tag is actually looking good in my eyes.

Wrap up

While the Asus Zenbook UX31 still has its flaws, it is one of the best, if not the best available ultrabook on the market.

Basically, if it weren’t for the poor keyboard and trackpad (the latter actually seems to be improved on the newer models available for sale in 2012), I’d recommend this one hands down. It’s good looking, solid built, has a very good screen, excellent speakers and solid battery life and performances. All these with a decent (while still above most competitors) price tag.

Don’t forget that I’m a blogger thus a good keyboard is a primordial aspect in my book. If you’re fine with a less-than-perfect typing experience, the UX31 might be just the one for you. For me though, the Lenovo U300S remains my favorite ultrabook so far and the UX31 is a close second.

If only I could get a mix of the two… perhaps with the 2nd generation of ultrabooks.

    Hi, I find your review very enlightening.
    I need to know how to find one of these notebooks with the new Elan touchpad. Serial number? Manufacturing date?
    I’m especially looking for these UX31 machines, as I need to have an all around metal computer (I can’t tolerate plastic). I just want to make sure I choose the right model. :)
    Thanks.

      Not sure what to advise here… You should ask the shops exactly for this particular detail and make sure you can return the product just in case it doesn’t come with an ELAN… Sry I can’t help you more here

    This Asus is easily found now at many retailers. I’ve had this Asus for 2 months now and can’t stand it because of the touchpad. I use it with a wireless mouse, but frequently work in situation where a touchpad is needed. I have the Elan touchpad and it is absolutely not good enough. Wait on this one until Asus gets it right. It’s a really bad touchpad if you work on the computer very many hours a day.
    Good about the laptop: love the battery life.

    I have the UX31 and have no problems whatsoever with the keyboard and Elan trackpad. Although I prefer to use a mouse anyway when I can, when I do have to use the trackpad I find it quite smooth and consistent, and the multi-touch gestures work fine. Overall I’m very pleased with this laptop.

    Well I finally went and got myself one of these. The UX31e.
    I’ve been testing it and all I can say for now is that I’m pleased with the machine. I’m only using it for pretty boring stuff, I don’t even do games and all that. So, overall I’m happy with it.

    Thanks!!

    I’ve owned a Toshiba Laptop for many many years. I decided (after two weeks of on line research) to purchase the UX31E. I’m very pleased with it. I got it with the 256 GB SSD. Kind of weird there was a “C” drive and also a “D” drive in the SSD hard drive.
    I had some help but now have consolidated both drives into JUST ONE hard drive, labeled “C” The keys will take a little getting used to, I believe. You definitely have to push each with a solid touch to get them to register…… I can highly recommend this unit, however.

    I bought my Asus Zenbook UX31E in January. The PC itself is a fantastic pease of machinery, however I can’t use it due to the faulty keyboard. For those who use the SFT (Search, Find and Type) methode with one finger, it’s probably good enough, but using the touch method when typing, it misses so many entries that it just don’t gives the money worth buying it.
    I will try to claim the money back after trying to get used to the keyboard for 3 1/2 months now. I’t just don’t work as espected. A keyboard should register all the entries when you press down the keys. It’s as simple as that – and it doesn’t.
    If I successfully can deliver it back and and revoke the purchase, I will try to go for the Samsung 5 series instead. I have tested the keyboard on that one, and it’s just delightful to type on.
    The question is if ASUS will deny the request and keep a customer for later purchases or if they will just get rid of the unusable machines, knowing that one single unsatesfied customer doesn’t wreck the future for them.

      I doubt you’ll be able to get your money back after such a long time, but please let us know what happens.

    The Elan trackpad is very bad….I ALWAYS plug in a wireless mouse and then NO Problems. I go into the settings and disable the Elan mousepad so I don’t inadvertantly bump it……now I’m very happy with the computer. Still have to “push” rather hard on the keys to make them register, though……getting used to it. It runs very very cool and is amazingly fast.

    Hi,
    I like your reviews. I’m having difficulties deciding in choosing the right ultrabook.
    Please help me in deciding which one to buy out of Asus Zenbook UX31, Dell XPS 13 or Lenovo Thinkpad X220?

    Thanks

    Regards
    Gaurav

      Guarav, the X220 is not an ultrabook. It’s heavier and thicker. Otherwise, I can’t really help you unless I know what you expect from such a device.

    hello mike… how to check a zenbook is using elan or not?

    i check it in registry, and check the software, is it right?
    thx

    • Mike

      July 11, 2012 at 9:04 am

      I don’t know what to say, but you should check the drivers for the trackpad, you will find answers there… Anyway, I searched for a method to see which trackpad is on a Zenbook before actually buying it, based on serial number or something, but I couldn’t find anything

      • Richwan

        July 12, 2012 at 3:28 am

        ok thx for your reply…

        and there is 1 problem about ssd

        i know the adata isfaster, so i am looking for zenbook that using adata

        but, i can not find it in my country (indonesia), so, is it worth to buy zenbook that using sandisk?

        or do u have clue, which zenbook is using adata? maybe from the seriar number, or something ?

        thx

        • Mike

          July 12, 2012 at 10:01 am

          From what I know, there aren’t easy ways to see these details from a serial number. But you should ask the same question in the Asus U31 thread on notebookreview.com, on their forum.

          Also, the Sandisk is considerately slower in benchmarks, but i don’t know if you’re going to easily notice that speed difference during real life use…

            July 14, 2012 at 4:24 am

            ok thx for your advice

            btw, i confusing to choice between ux21e or ux31e

            i love the ux21e size, that is the real “ultraportable” , but the screen resolution is not good for me to work.

            i use the zenbook when i go to vacation only, i use it to work, no gaming, no watch full hd video

            i have to browse internet, download, chat and do some excel to finish my work, so i need higher resolution, and i will get a bigger “workspace”, but the ux21e size is perfect to me in vacation, so i really confusing to choose between this 2 type of zenbook

            any advice?
            thx

          • Mike

            July 15, 2012 at 12:33 pm

            Well, I for one did not digg the screen on the UX21. Besides the low-res, it also has poor viewing angles. But, the newer version, the Zenbook UX21A, might just fix those. Also, the first gen UX21 got really really hot when pushed, but since you’ll only use it lightly, that shouldn’t be an issue for you

    Hi Mike,

    I am looking for an ultrabook with optical drive and 15.6/15 inch screen size and a battery back-up of atleast 6-7 hours. I had zeroed my options in on Acer Aspire Timeline AS5810TZ, but all the ports being at the back of the laptop made it highly unsuitable. I recently came across ASUS S56CA series, it’s got 15.6 screen size, a DVD optical drive with I3/I5 option but i have no idea about its battery life.

    Would you know about its battery life?
    And could you suggest any other options?

    Thanks.
    Amit.

    I would not recommend Asus zenbook to my dog. Yes, the zenbook is pretty/stylish. Unfortunately that’s it! It’s not worth $1500. I brought mine a little over a year ago after doing extend research before spending that $1500. And guess what most of those fascinating reviews were lies. That’s zenbook has got to be my worst experience with a laptop ever. I’ve send my zenbook in for repair over fives for manufacture default. And now my laptop won’t even bother turning on. Don’t buy. Don’t buy. It’s best you burn that $1000-$1500 then to waste on that zenbook. At least you’ll save yourself the aggravation and headache.

    Marie,
    That’s a shame. I’ve had mine now for a little over a year and have had ZERO issues or complaints. I’m still not thrilled with the way the keys work (you have to push them harder than I’d like), but I would definitely purchase mine again, if I had to make the choice. It’s light (I travel a lot) and has GREAT battery life. (I don’t work for ASUS, but sorry you’ve had a bad experience).
