Lenovo IdeaPad S12 Review

by Charles P. Jefferies

The Lenovo IdeaPad S12 features a 12-inch screen and is one of the largest netbooks on the market. This 3.42-lb machine is designed to let consumers easily surf the Internet and perform other light tasks on-the-go without having to spend a lot of money. The S12 comes pre-loaded with Windows XP, has a full-size keyboard, and includes a six-cell battery for five hours of run time – read on to see how it fared in our testing.

Our Lenovo IdeaPad S12 review unit has the following specifications:

• Intel Atom N270 processor (1.60GHz)
• Windows XP Home Edition
• Intel GMA 950 integrated graphics
• 1GB RAM
• 12.1-inch widescreen display (1280x800) with LED backlighting
• 160GB 5400RPM hard drive (Hitachi HTS543216L9A)
• 6-cell Li-ion battery (11.1V, 52Wh)
• Broadcom 802.11b/g wireless
• One-year limited warranty
• White color (also available in black)
• Dimensions: 11.5 x 8.5 x 0.9 – 1.4 inches (W x D x H)
• Weight: Starting at 3.42 lb w/ 6-cell battery

As configured, our S12 is currently priced at $499. The base model starts at $449 with a VIA Nano 1.3GHz processor.

Build and Design
Since all netbooks have nearly identical specifications, manufacturers have to look at the design and build quality to differentiate themselves. Lenovo's IdeaPad S12 is a docile and friendly-looking machine with a not a square edge in sight. The company's second generation of netbooks feature rounded edges and a slimmer chassis. The S12 looks well built; all of the parts fit together neatly.

The back of the lid has a "fashion" design with hundreds of little circles dotting the lid. The S12 would be at home in a Target store because I think all of those little circles resemble the company's bullseye logo. In addition, the majority of people I showed it to thought it was a girl's machine, probably because it is white and has that circle design on the lid. Your mileage may vary – I suggest guys go with the black version.

The S12 is constructed of ABS plastic through and through. It looks and feels sturdy and is not fragile at all. The only part of the notebook that could be more solid is the battery, which wobbles ever so slightly. There is little flex anywhere on the machine, with the exception to this being the lid; ripples show on the screen when only mild pressure is put on the back of the screen. This should be a non-issue as long as the machine is not thrown around. The hinges that hold the display on are very solid as well. A point of interest about the lid is that it only tilts back about 20 degrees past vertical; given how light this machine is, it will likely be used in a variety of situations and therefore should probably tilt back another 10-20 degrees or so.

The entire base of the notebook has a matte finish, while the lid is glossy plastic front and back. The glossy plastic is surprisingly durable; I did not use a sleeve to protect the S12 in my bag during the week I had it and there were no scratches at the end of the review period.

The glossy screen attracts dust and fingerprints easily, so keep a microfiber cloth handy. As far as cleanliness goes, the white plastic stayed clean during the time I had it; only time will tell how it fares in the long term. Hopefully the plastic is not too absorbent and will not pick up stains and other discolorations. The black S12 is be better at hiding everyday wear and tear.

Compared to the Dell Inspiron Mini 12, a direct competitor to the Lenovo S12, the S12 is slightly smaller (albeit about a tenth of an inch thicker). The S12 feels deceptively heavy in the hands depending on how you pick it up (by the back, front, and so on). The stick-out 6-cell battery is the primary reason the S12 feels weighty.

Overall, the S12 has excellent fit and finish with an accommodating design.

<!--nextpage--><!--pagetitle:IdeaPad S12 Screen and Speakers-->

Screen and Speakers
The S12 has a 12-inch widescreen display (16:10 aspect ratio) with a 1280x800 resolution and LED backlighting. Contrast and brightness are excellent; the LEDs lighting the display (instead of the traditional CCFL lighting used in most notebooks) make for a very even brightness distribution, with only a hint of bleed at the bottom. There are ten levels of brightness; I found level 7 or 8/10 to be the sweet spot, but dimming the screen to 4 or 5/10 are perfectly usable and will extend battery life. The top brightness level is almost too bright. Viewing angles are average at best &ndash; from above the picture washes out quickly, and from below it darkens. Side-to-side angles are better but there is noticeable color shift.

Unfortunately the glossy screen coating means a lot of reflections, so using this machine outside or areas with a lot of lighting sources could get annoying.

The 1280x800 resolution of the display is excellent for a netbook; most have 1024x600 or less. The display also has a 16:10 aspect ratio, which is unusual since most manufacturers are moving to 16:9 displays. The higher resolution makes the S12 feel more like a full computer than other netbooks with lower resolutions.

There are two speakers located beneath the palm rests on the S12. These are essentially stereotypical notebook speakers &ndash; they get loud enough to hear sounds and are reasonably clear but for situations where audio matters, like movies and music, do make use of the headphone jack.

Speaking of the headphone jack, it is unfortunate that some background hiss is present. It is easily drowned out with audio and most people probably will not even notice it, but to a headphone audiophile like myself, it is disappointing.

Keyboard and Touchpad
The IdeaPad S12's keyboard is, in a word, superb; it is full-size and requires no adjusting from a standard notebook keyboard. There is no flex and key travel is just right. The keyboard feels of high quality and allows for precision typing; each key is anchored securely and does not wobble at all. It has excellent tactile feedback and enough resistance that you can rest your hands on the keyboard in typing position without pressing keys accidentally. Lenovo designers made good use of the keyboard real estate &ndash; I am pleased to see the PrintScreen key is its own key and not mapped as a secondary function (as in, needing to press the [Fn] key in conjunction with the corresponding key to use it), and that the PgUp and PgDn keys are near the arrow keys. The Home and End keys are secondary function keys, but looking at the space the designers had to deal with, it was clearly not an option to make them separate as well.

All in all, this is one of the best netbook/notebook keyboards I have used in a long time.

The touchpad has its ups and downs. While tracking is easy and it is reasonably accurate, it is a bit too small &ndash; I found myself running out of room often. If it measured a half-centimeter more in diameter, it would be perfect. The touchpad buttons provide good feedback and make an audible but not annoying click when depressed. The buttons are easy to find by feel and other than wishing they were slightly larger, I have no complaints about them.

Ports and Features
The IdeaPad S12 has a limited selection of ports &ndash; let's take a picture tour. All descriptions are left to right.

Left Side: Power jack, exhaust vent, wireless on/off switch, two USB, media card reader (MMC/MS/MS Pro/SD)

Right Side: ExpressCard/34 slot, headphone and microphone jacks, USB, VGA out, 10/100 Ethernet, Kensington lock slot

Front: Stereo speakers

Back: Battery

The S12 has the essentials; given what a netbook is designed to do, the port selection is difficult to complain about.

<!--nextpage--><!--pagetitle:IdeaPad S12 Performance Benchmarks-->

Performance
I used the S12 more or less as my primary computer for one week and I quickly found out what a netbook is good for and what it is not good for. Its Internet surfing performance is reasonable, as is its performance in most everyday activities such as playing music and reading email. OpenOffice.org ran without any hitches. I was able to use Firefox and listen to iTunes simultaneously without trouble.

That said, doing anything more strenuous than surfing the Internet can quickly overwhelm the Intel Atom processor. Despite its Hyper-Threading technology, which makes Windows think it has two cores, the Intel Atom is still a single-core processor and a very limited one at that, and therefore multitasking with several programs is not going to be smooth. Alt-tabbing between applications is not instant. In everyday performance, users coming from faster computers will notice programs take longer to open, web pages take longer to render, and in general performance is toned down a notch. Going through ten megapixel images and trying to watch high-res movies from my video camera were clearly too much for it to handle. Know the limits of a netbook before you buy one.

Overall, the S12 is what a netbook is supposed to be &ndash; a more portable compliment to a user's primary computer. I found the S12 to be a great companion at work &ndash; I used it to listen to music and keep a web browser with my email open. For everyday tasks, the performance is just fine.

All netbooks generally have the same specifications and therefore will have nearly identical performance. Nonetheless, we run a full set of benchmarks for each netbook reviewed.

HDTune for the hard drive performance:

Heat and Noise
The S12 has one small cooling fan which gently pushes lukewarm air out of an exhaust vent on the left side of the machine. The fan is on the majority of the time while in use. The fan is nearly silent &ndash; I had trouble hearing it when there was any background noise.

The surface of the S12 does not get warm at all &ndash; there are no noticeable hotspots on the bottom or top of the machine. The S12 is a very good choice for those wanting a quiet and cool machine.

<!--nextpage--><!--pagetitle:IdeaPad S12 Battery Life and Conclusion-->

Battery Life
At half brightness (5/10) while typing this review and surfing the Internet, the S12 managed five hours of battery life. Lenovo includes a custom power configuration utility with the S12, from which I used the second-most power conscious setting, Low Power. Lenovo claims the S12 can go for six hours, which I suppose could be reached using the Super Energy Saver profile, but it sets the screen brightness down to near zero and barely anything is visible on the screen. Under normal use, expect the S12 to be usable for at least four and a half hours. With a power-saving SSD instead of a mechanical hard drive, I imagine the battery life would be a bit longer.

Conclusion
The IdeaPad S12 is excellence in a small form factor at a low price. The overall design is very pleasing to the eyes and it has the best netbook keyboard I have used to date. Build quality is solid and the screen is beautiful. There is little complain about on the S12 &ndash; sure, the touchpad could be a bit larger and the screen could tilt back further, but other than that, if you are in the market for a netbook with a larger screen, it is difficult to go wrong with the Lenovo IdeaPad S12.

Pros:

• Pleasing design
• Solid build quality
• Excellent keyboard and screen
• Five hours of battery life

Cons:

• Touchpad could be a bit larger
• Screen could tilt back further
• Back of the lid could use a bit more protection

Great review. I just wish one day Lenovo would come out with a ThinkPad netbook. Put a larger keyboard on it, paint it that rubbery black and it would be near perfection

 

+ thinklight

 

Thanks for the compliments guys, I appreciate it. It is impressive what the Lenovo designers were able to do with a 12" chassis - that's not a whole lot of space to work with.

I attached some comparison pictures of the S12 next to some other laptops - an HP dv5t (15.4") and a Dell Precision M6400 (17"). Enjoy.

 

I remember you were saying that netbooks were too small and uncomfortable for you

And I think what will make this netbook even better is future ION platform+ dual core atom...can't wait!

 

too bad theres no ION in this one yet =/

 

Thanks for this review. The alternative to this is the Samsung NC20 ( review here) that has been around for a few months, but it is now looking over-priced at $499 with the Via CPU and no Express Card slot.

A 12.1" screen makes a netbook much more usable. In fact, it becomes an alternative to a small notebook for users with limited demands.

John

 

Sure wish Lenovo or someone else would produce a 12" netbook with full size keyboard WITH a trackpoint in the keyboard.

 

Yes, I have an Lenovo S10, and would love to have a trackpoint. guess they can't fit it yet.

Nice review Chaz, and I agree about the touchpad, really tiny compared to the Toshiba netbook.

 

I know, especially it'll be great to see what Ion eventually evolves into especially if they keep pushing the platform. Chaz you mention the speakers but do you think the speakers are better then most 10" netbooks?

 

This is not a netbook. Its a 12" LAPTOP. Dont even waste your money on a 12" laptop with a crippled Atom CPU when there are countless superior 12" laptops with superior pentium M or CoreDuo CPUs.

12" laptop + Atom CPU = Fail

 

Aren't all netbooks just cheaper crippled notebooks? How many 12" notebooks are less than $500 with battery lives greater than 5 hrs? For some this is all they need.

Anyway, is the S12's RAM and hard drive easily upgradeable?

 

No netbooks are not notebooks. Netbooks are designed to be SMALL, much smaller than 12" laptops.

For $500 its a ripoff. You get a 12" laptop with simply awful performance.

Its like buying a 12" laptop with a celeron M 900mhz. You would you pay $500 for a 12" laptop with a celeron M CPU? No of course not but thats what Intel has designed the Atom CPU to do. Its to fool the uneducated into thinking "1.6ghz" cant be slow, when in reality its the same speed of laptops from 6-7 YEARS ago.

Eduction is key to understanding our reality. Please dont be fools everyone.

 

People who buy/want netbooks aren't looking for raw power in them, they're looking for battery life, portability, affordabilityand usability. The Celeron M cannot compete with the Atom when it comes to battery life.

While it's true that a 10" netbook would be much more portable than the S12, you sacrifice screen resolution and keyboard usability. Some would prefer to carry a slightly larger and heavier machine for those pluses, yet not break the bank on a powerful ultraportable, such as the Thinkpad X200 or Vaio Z.

Slightly off-topic: iGrim, you've constantly been trashing the Atom based on its lack of processing power, but I think you're missing the point. While it is true that a Pentium M of the same clock speed beats out the Atom in many (most?) cases, what's important to note is not the processing power of the Atom, but the processing power to power consumption ratio - that's where the Atom clearly beats the Pentium M. And that's also what is important in netbooks: battery life, rather than raw speed. People have desktops or powerful full-size laptops for that.

Overall, this seems like a quite solid machine. Great review, Chaz!

 

This is the first netbook review I have done so I honestly can't say; the HP Mini seems to have better-than-average speakers. The S12's speakers are like normal budget laptop speakers.

As noted, there's a lot to consider with the S12. It's designed to surf the Internet, not encode videos, and it's less than $500.
The Atom processor is quite impressive given its physical size and TDP/power usage.

 

They should have made it 10" and do something worthy out of it.

 

Again, eduction is key to understanding our reality. ULV Pentium M 1.3ghz uses 5 watts compared to the Atoms 4 watts. Wwwwwwooooooo what a big power savings a WHOLE WATT!

1.3ghz Pentium M is so superior to the Atom CPU its not even funny. You have to understand that Intel designed the Atom with intent to fool the uneducated general public with clock speeds. It has been well shown how AWFUL the atom CPU performs. 900mhz Clereon M beats the Atom in 80-90% of cases this means that Clock for clock the Pentium M is nearly twice as fast.

The Atom has over 40 million transistors. Intel could have EASILY made a 45nm 4 watt pentium M stlye cpu with 40 million. They didnt because they wanted to boost clock speeds simply to fool the uneducated public and they made it in-order design so that it would not compete with the celeron series in budget laptops.

Education is key to understanding our reality. This is why I under it.

 

To a degree I am certainly inclined to agree. I would much rather purchase a USED ultraportable from 3-5 years ago (e.g. ThinkPad x31, x40, or x41) with a 1.3GHz-1.7GHz Pentium M if I was going for a 12" computer at <$500.

I really don't think the Atom should be employed in anything over 9" (or possibly an ultra low cost/low power home server with an ITX board like the BOXD945GCLF2 where performance is not required).

 

@iGrim: You completely forgot to factor in cost. The Pentium M ULV 773, which you are referring to, came out at $250+ per processor, whereas the Atom N270 costs ~$40. True, you won't get as much performance out of the Atom. But, that's hardly the point with the Atom, a cheap and power-efficient processor.

In either case, the conclusion is that the Atom certainly isn't for everyone.

 

SIGH.....Honestly is anyone even listening to what I posted? Im going to try to explain this again in simpler words.

1. CPU cost = Dye size

2. Atom = 47 million transistors

3. Pentium M with 512kb L2 cahce would = ~47 million transistors

Pentium M cost alot in the beginning because cost per wafer was high due to the 90nm Mfr process and its large 2mb cache which took up alot of the dye space.

Pentium M w/ 512kb cache has nearly the EXACT same amount of transistors as the Atom CPU. If Intel developed them on the same 45nm process of the Atom then cost would be the SAME since dye size would be the same and power requirements would probably be even LOWER than the ATOM as 5 watt ULV Pentium M CPUs were made on old 90nm. Actually cost would probably be even LOWER since they would not need much R&D.

 

iGrim, you seem to know a lot.

I'm looking for a 11"-13" ultraportable and wonder if you know of any new models out there that are around that size, 3.5lbs or less, around $500 with a battery life of more than 5 hours.

Currently I'm looking at netbooks and the Acer Timeline 3810T.

 

Dell has an 11.6" machine coming in August that will use Celeron/Pentium and maybe Core processors.

 

I think we all agree that the Atom isn't the best CPU. And yes a Pentium M 1.1 would be a better choice IF it was available. But in the current new laptop market it's not.

Reality is that the Atom has enough power for websurfing, office, music and some video. Which are the main usages for a netbook.

 

Thanks Jayayess. There's always something new coming out...

 

Well said. I use an Asus 1000HE as my main computer and it's more than enough power for me. I do wish it were able to do flash-based content better but I blame that more on Adobe.

The S12 does interest me but it seems like a bad time to buy a netbook since they aren't included in the Windows 7 upgrade offer and I'm thinking most manufacturers will begin to include Windows 7 on netbooks when it's out.

 

The S12 is an interesting offering, especially since the only competitors are the Dell Inspiron Mini 12 and Samsung NC20. Rumors of the Dell's demise have been floating for months (and it's even in the current catalog), and sales have been weak, at best. I'd be interested to know how the NC20 is selling...

Regardless, the 12.1" display and keyboard of the S12 would appeal to me over any of the smaller netbook offerings. The choice of two platforms is also very interesting (VIA Nano or Intel Atom). But the VIA Nano-based model has disappeared from the Lenovo website...will it ever return? That only leaves the $499 Atom-based model. With some smaller netbooks selling for $299 or even less, $499 seems a bit steep. For $500, it's very close to CULV notebook territory....

 

The FN key appears to be awkwardly placed in this unit. Shouldn't have to remap it due to the manufacturer deliberately going against comfortable norms IMO.

 

Don't all IBM / Lenovo notebooks put Fn in the corner? Samsung used to do this, but changed last year.

John

 

Finally, the IdeaPad S12 turned in slightly weak performance on our iTunes encoding test (21 minutes and 6 seconds) and Windows Media Encoder tests (28 minutes and 19 seconds).

Lenovo promises up to 6 hours of performance from the six-cell battery. If you're looking for an affordable, comfortable, light notebook for primarily online work, the Lenovo IdeaPad S12 is a great choice.

 

These 12" machines should start being called "sub-notebooks" rather than netbooks. Why would a rational consumer buy a weak-performing S12 for essentially $500, when one can get a slightly larger dual-core notebook on sale for the same price? It doesn't make any sense.

I just bought an eee PC 1000HA with the new chiclet keyboard for just over $300, and couldn't be more pleased. That is the essence of what a netbook should be: cheap, portable, with a long-lasting battery.

Even Asus is getting confused, as they are about to debut a new eee with a CD/DVD slot. Just dumb, in my opinion.

 

About the [Fn] and [Ctrl] keys being switched - there are a number of notebooks on the market with that kind of setup. It takes some getting used to but after a week it was natural to me.

 

I know some Gateways had that (our ones at school do), it is not bad but if you use cnrl alot it does get annoying pretty quick.

 

Any set date for the ION S12?

 

I wanted the Ion S12 also but I found out that Ion's give up the express card slot. It's replaced with the HDMI port.

 

We've been testing the S12 for a week now. Excellent netbook. Yes, it comes with all the limitations of the N270 Atom. We know it's not great for gaming or hardcore apps.

But for a portable with useable (and bright, crisp) screen and SUPERB keyboard, make this a stellar choice. The battery life is pretty darn good. We get about 5 hours. I like the design too: classy, black, sophisticated.

We have noticed some quality issues. The 6-cell battery "wiggles" slightly, apparently not locking in firmly. Not sure if this is just our unit, or all.

Runs Win 7 perfectly.

Speakers not bad.

Expansion slots easily accessed at bottom (but, alas, not hard drive).

We actually did a LIVE stream broadcast using the S12 and it worked!

For permanent laptop, I'd consider it only with ION, however, as the Intel graphics chip will not do HD or even some HQ very well. But otherwise, A+.

 

how's the battery life under windows 7?

 

Battery under Windows 7 is surprisingly good considering it's driving a bright 12" display. I'm getting about 5 hours on average. Can go longer with dimmed and no video. It won't match the 10" guys, but it's decent. Also charges quickly too.

 

I just picked one of these up @ $350 + tax

The extra 2" screen makes all the difference.

Loose battery seems to be a common issue, but just apply some tape on the inside of the battery to tighten it up.

High Definition 720p / x264 / MKV movies will play FINE.

Youtube / Hulu - SD works fine, forget about HD..
