4.0 out of 5 stars And on the third day... the touchpad got me! (touchpad fixed) July 9, 2012

By geekinma

Style Name:Core i5| Size Name:128GB|Amazon Verified Purchase

I have had this laptop for about 3 days now. I had been wanting the zenbook since the original UX31E had come out, but held back after the reviews about the keyboard and the touchpad.

The new display on the ux31a was an instant sell. Having used nothing but high resolution laptops, i had hung on to my trusty HP 6820p for 4+ years.

The reviews for UX31 are mostly on the mark, but strangely somehow still fail to point the one "true" issue.

Now moving on to something more useful..

1) The display is to die for. I spent an hour with the retina mac pro, while i didn't see both the screens side by side. I'm ecstatic that ASUS is finally pushing laptops to move up from the resolution backsliding going on for the last 5 years. You will not miss the retina display on a mac with this. Half the price is just a bonus.

2) It is _light_.

3) The biggest showstopper is the touchpad out of the box. Yes, i'm referring to the touchpad on ux31, not the older ux31e. Multi touch etc. etc. works well. (have two macs at home for comparison). The thing that just about ruins this little gem is the horrendous behavior of the touchpad when your palm brushes it during typing. There is no way you can really avoid this, and it is impossible to do any typing without the cursor moving and the tap to touch causing irritating behavior. (like prematurely sending an email, closing the email, clicking a background app into focus). How this went past anyone in any QA dept. is beyond me. It's that bad, just typing a 2 line sentence is near impossible. This was entirely preventable with just a bit more diligence by ASUS. This one problem is bad enough to warrant a return if it weren't the fix that later became available.

I upgraded the drivers to the THEN latest on the ux31a page on asus support. They didn't work any better. Update: ASUS has finally put an updated version that addresses the issue much better.

Initially i was concerned that I was out of luck and that this could be a trackpad hardware limitation. Thankfully a bit of investigation digging through the registry in the HKLM\CurrentControlSet\Services\ElanTech revealed a plethora of values that seeemed promising.

Further investigation led to a rather huge thread on this topic on the laptop support forums for the elan trackpads on Samsung laptops. A bit of spelunking revealed an updated driver (10.7.16.1). This one proved to be a winner. Not sure if it was the actual driver update, or the very significantly different configuration settings in the registry that made the difference, but at the end of the day the problem is mitigated nearly completely (and without disabling the trackpad while you are typing).

I think there is still some fine tuning to do with the relatively sensitive trackpad, but am a bit more at ease as I think it's just a matter of tweaking the settings just right. I think the elan folks will get it right with just a bit more time. I wish the control panel utility gave you more tuning options without having to figure it out on a trial and error approach with the registry variables. The newer version samsung is using has an 'advanced' tab which seems to be heading in this direction

This is my first ever review and I am only writing it because I really dig this laptop. I'd hate to have this not succeed due to the egregious trackpad palm detection issue. Asus's strength is clearly not software QA.

A few other observations that I haven't seen mentioned before.

4) The adapter when plugging into socket always seems to spark as it's plugged in. I haven't seen this from any other adapter, so am wondering about the reliability. It also seems to run a bit hot compared the mac one. This is just an observation, not an issue (i had no less than 5 adapters fail with the HP). Update: I was looking for additional adapters so I don't have to keep carrying the one around, they seem to extremely expensive online, ~$120. There are non ASUS brands available all the way down to $15, so will probably try one of those, I wonder what the difference is. I suspect it's to do with the charging logic / led indicator on the OEM one. I thought the charging controller was in the laptop and not the adapter, but not entirely sure about this now.

5) The keyboard is just fine, I saw some posts ranting about ux31 keyboard, and i don't know what they are talking about. It's pretty good, and i type reams.

6) There is bleeding of light at the bottom of the lcd, but it's a non issue and an observation i made only because I read about it on other reviews.

7) The keyboard backlighting is nice to have.. but again, don't think it's as big a deal as it's been made out to be when it was missing in ux31e.

8) The display hinge is just fine, it holds up well. If you suddenly lift it, then there might be a tad amount of sway. I think it's only because this laptop is so thin and light that people apply more g's. (I couldn't do that with my old laptop with both my hands if i wanted to because it was so heavy). It feels pretty sturdy compared to the luddite laptop i am used to.

9) I had tried win 8 for a short period on this laptop, seemed to work about the same. (Reverted to win 7 for work reasons after an hour or so).

10) The battery seems to last 6+ hours with just web browsing / email..

11) The wifi has been working well, no problems so far. The previous HP laptop I had would lose WIFI connection whenever the microwave went on for a minute. This one hasn't exhibited that problem.

12) The USB to Ethernet adapter is unfortunately 10/100, not Gigabit.. and for me it's a big deal. Copying around large VMs is the norm and this limitation is a rather big issue. The limitation seems to be from the PHY ASUS is sourcing from 'asix'? They seem to have a new USB3 to GBE part available, so I'm sure in future models this limitation will be addressed. I wonder why they didn't go with USB 2 to GBE phy as it seems to have been available for a while. It works well, counter intuitively its actually proving to be nicer to use the USB connection than the RJ45 jack.

13) The built in VGA adapter worked great when using a projector. Haven't tried out the HDMI out yet, need to go buy a micro HDMI cable.

14) Headphone out works fine, another reviewer mentioned an issue so tested it just in case.

Rating a 4, due to the trackpad runaround that's now resolved. Folks with trackpad issues should just get the latest version from ASUS or Samsung support site. I prefer the Samsung driver.

5.0 out of 5 stars A solid ultrabook June 21, 2012

By Eric

Style Name:Core i5| Size Name:128GB|Amazon Verified Purchase

Edit: My second laptop doesn't have any problems. I'm getting about 5 hours of battery life while doing light programming and listening to music on auto-brightness (there's a brightness sensor) which sets the display at about 60 percent brightness indoors.

I received this laptop a few hours ago and I'm going to give my first impressions on the device.

Build Quality and Design:
Apart from the different color on the keyboard and lack of hideous script font above the keyboard that was on the original zenbook, the Prime looks about the same. Since this is the 31A, it has a Aluminum Unibody design, and from messing around with various Macbook Air's this device seems to be just as well built. I like the front panel design over the Air but that's down to personal preference.

Accessories:
Being an $1000+ device I would expect a nice amount of goodies, and included is a VGA and Ethernet adapter. There is no micro-HDMI to HDMI adapter, but I find myself using VGA most of the time when giving presentations anyway, so I suppose that's not too bad of a loss. The Air (afaik) does not come with these adapters so that is a small plus. The adapters have their own little pouch to store separately. The combination synthetic leather/canvas sleeve that is included fits fairly snugly, though there is enough space to cram in an adapter if you need to. The AC adapter is about the same size as the Apple counterpart, which is good.

Screen Quality:
Being a UX31A the laptop packs a 1920x1080 Matte IPS panel. In a not-very-scientific test viewing angles (obviously) far exceed that of my desk TN panel, and brightness and contrast all seem to be much better. Granted, I'm comparing to a 23" Hanns LCD I paid $60 for. There was a comment earlier about the screen being dimmer than that of the previous gen, and I haven't tested it outside, but it seems to just fine for my purposes. The matte finish is also a plus. There is a bit of back light bleed on the bottom and right hand sides of the screen, but when watching a sample 1080p movie, it didn't bother me at all. I like the increased resolution on the device and it's a definite step up from traditional 1366x768 panels. Text is sometimes a bit small on the default size in chrome but that is easily remedied.

Performance:
Thankfully, an ADATA XM11 128GB SSD is included. This is a Sandforce drive and I'm getting benchmark scores of 470/150 MB/s RW Sequential, 18/44 MB/s RW 4K random, 113/144 MB/S RW 4k Random 64QD, and access times of .155/.277 ms RW, for a total score of 462 in AS-SSD. This is comparable to my old Vertex 2 in my desktop, so no worries about disk performance here. The system boots boots in about 20 seconds and resumes quickly. It scores a 7.9 WEI in terms of disk performance, though that's not a the best indicator in general.
I haven't done anything intensive with the CPU yet but things seem to be holding up well with little slowdown. I also tried messing around in Diablo III on the integrated HD4000 graphics. I set the game to 1024x768, and everything else to minimum, and from a short session of Act III Inferno, the graphics performed okay, with some stutter and slowdown depending on how many effects were on the screen. If you want to do more than just casual gaming, go for the UX32VD with the GT620M graphics. After playing for a bit the fan kicked on and hot air began coming out of the vent located above the keyboard. The fan was not loud enough to hear over the speakers, which put out a decent amount of volume for the size of the laptop.

Keyboard/Trackpad:
Asus touts the keyboard as being much improved over the previous generation, though I'm not sure if I notice that. I've tried out the original zenbook at stores a few times and this feels similar. I've typed this review on the keyboard without any problems, but it'll be clear to you that you are typing on a scissor-switch laptop keyboard. This also leads to me to the flaw in my item - the backlight. Two of the keys in the center refuse to light at all, regardless of the brightness level I set. Hence, it's going back to Amazon for an exchange. Pity. The trackpad is made by Elantech, which may make some people cringe, but for the most part, I haven't had a problem. I like to rest one hand on the left click button and right other to scroll, and there were no glitches I noticed in the last few hours. The only multi-touch feature I really use is two finger scrolling, which works well enough in Chrome. It's not as smooth as OSX is, but I would assume that is because of Windows 7, and will be improved in Windows 8.

If you're trying to decide between this and the Air, it mainly comes down to a few factors - OS, Screen Quality, Discrete Graphics, and support. If you have a rabid obsession with one OS over the other your choice should already be clear. If you value screen quality, both are solid choices - while the Air has a 1440x900 TN panel, it still looks good, though the viewing angles are likely not as wide, and the resolution obviously lower. Anandtech rates both this laptop and the Air well in screen quality. If you value discrete graphics, only the UX32 line offers you that. If you value support I would go with the Air, as nothing beats being able to go into a store and coming out with a fixed laptop.

If you're set on Windows or want a 1080P IPS Panel, no other ultrabook touches the Zenbook prime right now. Sony has a similarly-specced laptop out, which has a GT640LE and 1600x900 screen, but that is much heavier and thicker. This is an expensive device, no doubt, so if you can give up some screen quality and are okay with slightly slower integrated graphics, you should consider a previous gen ultrabook.

5.0 out of 5 stars Possibly the best lightweight computer--ever June 26, 2012

By Rob Kerr

Style Name:Core i7| Size Name:128GB|Amazon Verified Purchase

I've owned probably 20 laptops in the past (my wife would probably say that's 17 more than I've needed). But to be honest, I've not loved any one of them. Each has come with some sort of compromise that kept it from fully meeting my expectations. Lightweight machines have been underpowered; small screens have had low resolution--leaving me yearning to plug into a full size LCD panel whenever I could; machines with fast CPUs burned my lap and had horrible battery life....and so on.

The Zenbook UX31A is the first computer I've owned that has everything I want: super light weight, solid build quality, fast performance, beautiful display, decent battery life, high performance SSD and (I am a touch typist) a keyboard with great tactile response. Using the UX31A is like driving a German car: everywhere you look, you notice the level of attention to detail in design, and you just know the designers really cared about the end-user experience and didn't simply set out to meet a specification as cheaply as possible.

Asus may have shot themselves in the foot, though: I'm so satisfied, I may not feel the urge to replace this computer for a long, long time.

What you'll love:
1. The full HD IPS display with matte finish is dreamy. Maybe you think 1920 x 1080 is too high a resolution for a 13" display? It's not! With text set to 125%, text is the "right" size, and the fonts are as smooth as a printed page--I can't see the individual pixels. The IPS makes for a screen that's readable at any angle--a godsend for me when the person in front leans their seat back in coach!

2. The keyboard is much improved from the last version, and has the exact feel of my MacBook (which to me is a good thing). The backlighting on the keyboard is a nice addition as well.

3. Instant on. After opening the lid, the computer is usable in around 1 second. Amazing.

4. The aluminum case is impossibly thin, making it super portable. Everyone who sees this machine can't believe it's a real, full Windows PC.

5. The DC power supply. I'm in love with a DC power supply? If you travel a lot like I do, then you understand. This isn't just a generic $2 item Asus sourced from eBay. It's an impossibly tiny power supply that weighs almost nothing and has an 8 foot cord that will reach from any conference room table all the way to a wall outlet. Yes, it's a small detail, but something I appreciate every time I use it.

6. Build quality. The solid metal case is completely rigid and exudes quality industrial design. A $1,000 product shouldn't feel like you got it in a box of cereal, and this one doesn't! Great job, Asus!

7. Bang & Olufsen audio. Remember when choosing a 13" laptop meant you live with a speaker originally designed for a wristwatch? Those days are over--watching video on this laptop is like watching it on your TV! Audio is loud, clear and has a full range of sound. You'll only use your headphones when you don't want to disturb others.

8. The included fabric envelope to carry the notebook is so good you'll actually use it! It's a heavy fabric envelope that I find superb for taking the notebook on short trips to the coffee shop or to a meeting where I only need to take some notes.

9. Runs Windows 8 (June Preview edition) perfectly. I scratch-loaded Windows 8, and while it takes some patience to get all the Windows 7 drivers and utilities installed on Windows 8, everything works beautifully.

What you may not love as much:
1. There's a downside to making a laptop that's thinner than legacy VGA, Ethernet and HDMI connectors--there's no room for them!! Instead, a Micro-HDMI and Mini-VGA connections are provided along with dongles that adapt to standard sized connectors. For wired Ethernet, a USB-to-Ethernet adapter is provided. Some ultrabooks are specifically made thicker expressly to include legacy connectors. For me, that's a little silly...an ultrabook should be as thin as possible! But if you disagree and don't like the idea of a dongle for making VGA connections, then you may want one of the thicker Ultrabooks instead.

2. The Zenbook doesn't have the longest battery life among all Ultrabooks. Maybe the thin case has a smaller battery than others? You'll probably get 5 hours or so of battery life on continuous usage. If you need another hour or two, there are ultrabooks can last longer. For me, I find that with the instant on enabled, I can go all day between charges...I just shut the lid when I'm not using the computer and open it when using it (similar to using an iPad).

3. The UX31A, like most Ultrabooks, has 4GB RAM soldered to the motherboard, and no way to upgrade RAM. I think this is really a shame, since I'd gladly have paid more to get more RAM as an insurance policy against what I might want to use the machine for in the future. However I find 4GB is enough for what I'm doing day-to-day, and I doubt most people using an Ultrabook for business scenarios will find they need more than 4GB RAM with Windows 8. However if you're editing video, this might not be the right machine for you.

Overall, I think Asus took the best Ultrabook and made it even better. The last version (the "E" model) was, in my mind, the best small Windows notebook on the market...but fell just a little short of the elegant design of the MacBook Air. This new model, however, has moved the bar up insanely high for other Ultrabooks, and in my mind eliminated any reason why a Windows user would switch to a Mac to get superior hardware designs. I have a MacBook Pro...and this is the first time I can honestly say I like a Windows laptop more than a MacBook!
