Lenovo Think Pad T400s

It seems a common trend at Lenovo right now is making super thin and lightweight ThinkPads. First the X300 hit the market, offering a super thin and lightweight chassis with the ruggedness we have come to expect from a ThinkPad. Now Lenovo has done it again with the T400, bringing a newer, lighter, redesigned T400s to the table. In this official review we show you what's changed on this new 14" ThinkPad, which even includes the legendary keyboard.

Build and Design

The new ThinkPad T400s looks completely revamped and polished compared to the regular T400. The chassis has slimmed down significantly, and the weight of the notebook has also dropped by almost a pound. The exterior is still wrapped in Lenovo's much-loved rubberized black paint, but the design just looks cleaner and less busy than previous ThinkPad models.

Looking inside, the main changes start to become obvious. Besides the new keyboard and touchpad that we will go over shortly, Lenovo changed the shape of the palmrest around the touchpad, with the touchpad resting flush with the palmrest instead of being slightly recessed. The screen bezel is smooth all around the perimeter of the display, unlike the T400 which shows rough plastic grids near the built-in antennas and cutouts near the light and webcam. Even when compared to the ThinkPad X301, the new T400s looks more refined. The speaker grills are larger and look better suited to the design. Even the fingerprint reader manages to blend in better, with an all-black design instead of gold and silver like past models.

Build quality is still fantastic, with barely a hint of chassis flex even as it has decreased in thickness. The screen has some minor side-to-side flex when open, but no more than previous models. Protection for the screen, even with the super thin cover is surprisingly good, showing only small amounts of screen distortion when you are squeezing the back of the display. The new chassis feels quite rugged.

With the thinner design Lenovo completely reworked the chassis for the T400s, and it looks completely different than the T400 once you start opening it up. The hard drive is now accessed through a panel under the left side of the palmrest, which is now 1.8" instead of the 2.5" found in the T400. System memory and Wireless Cards are found under a single access panel on the bottom of the notebook. Compared to removing the palmrest on previous models, you now just loosen one screw and pop off a single panel to upgrade memory. With most of the slots changing location to the underside of the notebook, removing the keyboard is now only required to replace a broken one, or to get access to a half-sized mini-PCIe slot used for Wireless USB on some models. I really hope future ThinkPads follow a similar design to the T400s, since it is so much easier to upgrade components now.

Screen and Speakers
The LED-backlit WXGA+ (1440 x 900) display on the T400s rates above average, with good color reproduction and very good peak backlight brightness levels. The display part number is LTN141BT08001, which may indicate that it has a Samsung panel. Colors appear bright and vibrant for a matte-finish display, and it has very nice contrast when the backlight isn't at the brightest setting. At 95-100% brightness the screen starts to look slightly washed out, which is pretty normal for higher brightness displays. My comfortable viewing brightness range for this notebook is between 50-60%, giving great black-levels and no hint of backlight bleed. Viewing angles are average for a TN-panel LCD, with colors quickly inverting or washing out as you Tilt the screen forward or back. With the matte finish and higher backlight power the screen is readable outdoors and quite visible in your car on a bright day.

Speaker performance was lackluster, but that is common on most business notebooks. They work well for streaming audio or having a VOIP chat, but for movies and entertainment the headphone jack is a much better alternative.

Keyboard and Touchpad
Yes, Lenovo significantly changed the look, feel, and layout of the keyboard on the T400s. After you pick yourself up off the floor from fainting, you will quickly see most of the changes are for the better. The feel of the keys remains mostly untouched from past models ... outside of the fact that the spacebar seems to click loudly if you press it on the edges. The biggest change comes with a redesigned function key section, offering larger "escape" and "delete" keys. Through in-depth research Lenovo found that those two keys were used more than other function keys. As a result they doubled the height, and moved the position of the insert key and F1 key.

I think the coolest difference is the new media buttons and power button. The power switch and mute keys light up when activated, so instead of the power icon showing up on the bottom edge of your screen, the button itself is the indicator. The caps lock button now features a translucent window with an LED that lights up to indicate the caps lock is turned on. One thing that is missing is an AC and battery indicator light facing you with the screen open, as they are now external only.

The T400s offers one feature I have yet to see on any other notebook to date: a speaker AND microphone mute button. While I am not sure how often I personally need to turn off my microphone, if you videoconference or use Skype frequently then a quickly accessed mute button would come in handy. Another minor change is the key tolerances have decreased, meaning there is less room for crumbs or dust to fall in-between keys.

The new touchpad is different, but I am having a hard time figuring out if that is a good or bad thing. The old design used a slightly rough matte plastic finish, which gave some traction and made it easy to move your finger around even if sweaty. The new design has a raised dimple finish with a softer texture that feels strange. I found myself increasing the sensitivity in the Synaptics control panel to make movement feel more fluid, but then found it too sensitive. It seems that you need to apply consistent pressure when moving over the new touchpad, where before it was easy to flick your finger across. I think if the bumpy surface was glossy or more slick I might enjoy it more.

Another change is the shape and size of the trackpad buttons. The buttons have a radius contour that goes through the buttons to the edges where they meet the palmrest. From a design standpoint they flow better with the notebook than previous attempts, and it is even easier to access them from the touchpad now.

Ports and Features
Port selection on the T400s has been greatly improved over the T400 model. New to the back of the T400s is an eSATA port for Storage expansion and DisplayPort out, giving you digital video from the notebook itself. Just like the T400 it has three USB ports, one through a combo USB/eSATA port. Lenovo has kept the VGA port for legacy connections, since it is still used frequently for projectors. With the decrease in thickness the T400s lost its dual card slots, only keeping an ExpressCard/34 slot. The T400s offers a docking station connector on the bottom, but it is a new design that is incompatible with older models. The last big change came with the T60, and I can just hope that this docking station format stays the same for a few notebook generations to come.

Internal features include integrated 3G WWAN and a handy GPS receiver. While 3G is pretty common these days GPS seems to always be passed over. Lenovo includes software for initializing the GPS receiver, and translating the NMEA data through a virtual COM port for applications. Since I am fond of Garmin GPS receivers, I installed a trial version of Garmin Mobile PC. Installation was simple and the software will automatically find the virtual COM port for communication with the GPS unit. The T400s was quick to acquire our location with a six satellite lock inside our office. So if you don't own an automotive GPS receiver yet, this $60 piece of software might come in handy paired with the T400s.

Performance and Benchmarks
With an Intel Core 2 Duo SP9600 and 128GB Samsung SSD the T400s was no slouch ... despite the Intel X4500 integrated graphics. The T400s was extremely fast to boot, and was quietly waiting at the desktop idle much sooner than other notebooks we have reviewed. The T400s handles day-to-day uses, such as typing a paper, watching Hulu while the boss isn't watching, or enjoying an HD movie all with ease. Gaming presented a problem with the X4500 integrated graphics, so instead of playing Left 4 Dead you might have to compromise with Peggle. 720p and 1080p HD video decoded with no problems at all thanks to the fast processor, although outputting it to a home stereo might be tough without digital audio out through the DisplayPort. One original concern we had with system performance was the speed of the 1.8" drive, but as we found out the 128GB Samsung SSD included with our T400s blew the socks off most 2.5" drives. The only downside to this is the SSD is fairly expensive and the small size has few aftermarket options, whereas the 2.5" market is loaded with affordable alternatives.

Heat and Noise
The T400s managed heat and noise very well during our tests, keeping external temperatures low with minimal noise from the cooling fan. After continuously stressing the notebook over a period of 30 minutes the fan never went above a whisper level. You had to put your ear to the vent to hear it above normal ambient noise. Under light activity the case barely warmed up above room temperature. Under heavier loads such as watching an HD movie or playing a quick game the temperatures increased slightly, but overall stayed very lap-friendly. External temperatures listed below are shown in degrees Fahreheit.

Battery Life
Time on battery with the T400s was good, but not as impressive as the 10 hours experienced on the T400. Currently the only battery size offered is a 6-cell battery with a reported size of 45Wh. Compare this to the 9-cell on the T400 with a capacity of 84Wh, almost twice the size. Even with the smaller battery the T400s managed 5 hours and 48 minutes with the screen brightness set to 70%, Vista set to the Balanced profile, and wireless active. During the test power consumption varied between 6.5W and 8W depending on load. Compared to the T400 the power consumption drop most likely comes from the 1.8" SSD and integrated graphics chipset. Lenovo doesn't have plans to offer a larger main battery for extended battery life, similar to the 4-cell, 6-cell, and 9-cell options on the T400. What they will offer though is an ultra-bay battery to run in place of the optical drive, which should extend battery life by up to an additional three hours.

Conclusion
Overall I think Lenovo put a lot of time into thinking through the changes they made with the T400s so they wouldn't offend too many ThinkPad customers. The keyboard change is significant, but for all intents and purposes they stuck with the tried-and-true design. The keys feel the same, the core layout is the same, the only thing that changed were the function and media keys. Even though the keys look weird at first it takes about 3 seconds to adapt to the new layout. I think the super slim and lightweight design is excellent, moving to a layout that is easier to service by the end-user. The inclusion of eSATA and DisplayPort is something that should have come sooner, considering that the T400 doesn't offer a digital video output without a docking station.

The only complaint I have is with the price, starting well above the standard T400, and the costly drive upgrade options since it is limited to 1.8" models instead of the cheaper and more widely available 2.5" size. If you are in the market for a new ThinkPad and don't mind spending a bit extra for something thin and lightweight, the T400s is a great choice.

Pros:

• Excellent build quality
• Good keyboard changes
• Nice polished design
• eSATA and DisplayPort ... finally
• Very fast even with integrated graphics

Cons:

• Limited battery options
• 1.8" storage drive
• Different docking connector

Build and Design

The second generation Lenovo S10 looks great, with a cleaner and smoother appearance all around. In the redesign, the sides changed from flat surfaces that looked stuck onto the chassis, to a rounder and smoother form that looks integrated into the netbook. As a result, the new S10 is thinner in most dimensions, with varying heights depending on the inner structure of the notebook. The all-black model which we were lucky enough to get looks great, with every bezel matte black, except the screen lid which has a glossy black finish with a faint metallic weave pattern. Contrasting the black surfaces the Lenovo logo, power button, and touchpad buttons are all silver. This theme continues to the bottom of the S10-2, which if some of the stickers were removed would share the same clean look. My only complaint is Lenovo stuck with the large Windows COA sticker, instead of the new netbook-sized stickers that can be hidden underneath the battery or someplace out of sight.

Lenovo went with an extended battery that significantly improves runtime over the smaller flush-mount one. The downside to this is it sticks out the back, and raises the netbook up off a surface about 0.75". Some could argue that it moves the keyboard into a more comfortable typing position, or it works great as an extra handle. I would personally like one that just sticks straight out the back, making aftermarket carrying cases much easier to choose.

Build quality is very good, with firm plastic used throughout the chassis and very little obvious flex or squeaking when you are carrying the netbook around. The screen hinges feel solid, needing two hands to easily open up the display. The matte plastic finish on the inside and bottom of the notebook stayed scratch free throughout the review. Likewise, the glossy finish held up surprisingly well; it did, however, give us a few scares, making us think we created huge scratches... which turned out to be smudges. Even if you did scratch this model, the black finish hides most blemishes (including smudges and dust).

From an upgrade standpoint Lenovo really wins our hearts with its user-friendly design that puts every swappable component behind one of two removable panels. Under the main panel, we have access to the hard drive, wireless card, and spare mini-PCIe slot with the connector included (some don't solder this in place so they can save money). The other slot is for the system memory, which is expandable to 2GB total. The only thing that could have made this better is if they went with the HP Mini approach, which doesn't even need a screwdriver to open the RAM cover.

Screen and Speakers
The glossy panel on the Lenovo S10-2 is average compared to other netbooks, with bright and vibrant colors, but somewhat limited viewing angles. The glossy screen really does an awesome job at making colors pop, and also helps reproduce deep blacks as well - handy for watching Sci-Fi flicks. The downside to this and any other glossy screen, though, is added reflection, making screen visibility poor when outdoors or under a bright light.

Viewing angles seemed average, with colors starting to shift if the screen was titled about 20 degrees forward or back. Horizontal viewing angles just showed a slight hint of color shift, but nothing that would really bother you if you were sharing the screen with someone sitting next to you. Backlight brightness was perfect for viewing in bright office conditions, but might not have been strong enough to use outside. I spent a couple of hours out in my garage with bright shop lights on around it, and my motorcycle schematics were still fully visible from a few feet away. One possibly limiting factor of the screen design which might affect a few people is the limited hinge range, which prevents the screen from tilting completely flat. It stops the screen about 45 degrees back from vertical.

The speakers on the S10-2 are lap-firing, facing down underneath the palmrest. If you are listening to the speakers on a flat desk surface you can hear the full (albeit limited) range of the speakers, but if the notebook is sitting on a soft surface like your bed or lap, they get quite muffled. Music from the speakers sounds clear and crisp with excellent higher frequency reproduction, but falls flat with midrange and low-frequency support. For VOIP, streaming music, or YouTube they will probably work fine, but headphones would be the best option if you plan on watching a movie or are doing something that requires you to pay attention to all the little nuances of the audio source.

Keyboard and Touchpad

The keyboard on the S10-2 is a bit small compared to some netbooks, sticking with a condensed layout (instead of cramming in as much keyboard space as possible like what we see on the HP netbooks). This in itself isn't a bad thing, since you get used to it after a while, but coming from full-size notebook and larger netbook keyboards can be challenging. Keyboard support is excellent, exhbiting no flex or trampoline affect when typing. Individual keys feel sturdy with no wobble when sliding your fingertips across the surface, and key action is smooth with a very mild "click" given off when you trigger a key.

The touchpad is a Synaptics model with limited multi-touch support. The only multi-finger control you get in the control panel is "pinch", to zoom in on the cursor area. Just the same, sensitivity and speed were excellent, with no lag present in our testing. The size of the touchpad could be slightly larger or wider, to give a more defined scroll region. The surface texture is a smooth, almost gloss finish, which has decent traction but still lets a sweaty finger glide across the surface without sticking.

The touchpad buttons are easy to trigger, with only a light touch needed to activate them. Feedback is minimal with a very short throw. They both give off a mild click when pressed.

Ports and Features

Port selection is average compared to other netbooks, with three USB ports, audio jacks, LAN, VGA, and a Kensington Lock slot. Lenovo also includes a wireless on/off switch, SDHC multi-card slot, and an open internal mini-PCIe slot (probably for WWAN). One feature missing from the previous generation model is the ExpressCard/34 slot, but its uses are fairly limited for what netbook users might need.

Front: Activity lights, SDHC slot

Rear: Battery

Left: LAN, VGA, 1 USB, Mic/Headphone

Right: Wireless On/Off, 2 USB, Kensington Lock slot, AC power

Performance and Benchmarks

System performance seemed on par with many of the newer netbook models hitting the market. Boot and shutdown times were excellent, quickly coming up to a fully ready state without much waiting. For normal tasks such as web browsing, typing documents, playing music, or even watching video the IdeaPad S10-2 performed flawlessly.

Normally, users buying a netbook (outside of the ASUS N10 with dedicated graphics) understand that gaming just isn't going to be realistic. For this reason we find 3D benchmarks, which normally register very slow performance, to not be as relevant for these systems. Thus, we are shifting toward HD movie tests for netbooks, which are more in the realm of what a netbook can handle on the high end in terms of performance. In our HD video test the S10-2 played up to 480p and 720p video without much trouble. 720p video was starting to task the processor leaving little overhead, but it was very watchable. However, 1080p video was badly out of sync and painful to view.

In our ongoing quest to provide helpful information to our readers we are adding the following video playback table to our reviews of netbooks. Since netbooks are starting to be used for mobile entertainment (watching movie trailers or streaming video) it's important to know how a netbook performs when trying to play a simple video file. We selected a family-friendly movie trailer and downloaded three different versions in 480p, 720p, and 1080p resolutions. We used the CCCP Codec Pack for decoding and Media Player Classic Homecinema (version 1.1.796.0) for playing all of the video files.

Video Playback Performance:

Video Resolution	CPU Usage	Playback Comments
480p	20%-30% (hyperthreading)	Plays flawlessly
720p	44%-49% (hyperthreading)	Plays with an occasional dropped frame
1080p	50%-60% (hyperthreading)	Plays with severe stutter, dropped frames and audio out of sync

Heat and Noise
While performing normal activities (browsing the web, playing MP3s, typing documents, etc.) the Lenovo IdeaPad S10-2 ran fairly cool and quiet. The fan remained off during this time, which included the majority of our battery test. Under more stressful activity, like running benchmarks, watching HD video, or playing Peggle, the fan came on occasionally, but was quiet enough to not be a nuisance. On the top surface of the notebook, the only part that stuck out as warm to the touch was the touchpad, while on the bottom the heat was centralized around the RAM. If you are sensitive to heat or noise the S10-2 seems to be a pretty acceptable choice.

Battery Life
Battery life was excellent, but at the downside of having a gigantic battery sticking out and down from the back of the netbook. With the screen brightness set to 70%, wireless active, and Windows XP set to the laptop/portable power setting the notebook managed 7 hours and 15 minutes with light web browsing. During the test power consumption fluctuated between 6 and 7.5 watts.

Conclusion
The Lenovo IdeaPad S10-2 performed quite well in our tests, showing consistently better results that the previous model. The design looks much cleaner than before, and with the black color scheme, at least, the netbook is visually excellent. Battery life was improved, no doubt due to the large extended battery that sticks out behind and below, giving us over 7 hours in out battery test. The S10-2 handled 480p and 720p video without too many problems, but 1080p video was too much to ask for from the Intel Atom N270 and GMA950 chipset. Overall, the IdeaPad's price is very attractive, with a $439 MSRP - lower than previous models, and sale prices put it as low as $349. Our only big complaint is the rather cramped keyboard, but if you don't mind typing on the smaller keys the keyboard feels very well built and easy to type on.

Pros

• Good looks and excellent build quality
• Great battery life
• Good performance
• Easy to upgrade

Cons

• Keyboard feels cramped
• Extended battery doubles the thickness in the rear

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.

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 – 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 – 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 – 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 – 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 – 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.

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 – a more portable compliment to a user's primary computer. I found the S12 to be a great companion at work – 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 – I had trouble hearing it when there was any background noise.

The surface of the S12 does not get warm at all – 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.

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 – 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
