Lenovo ThinkPad X1 Carbon review: An enterprise-class notebook to fall in love with

Lenovo ThinkPad X1 Carbon Touch $1,215.00 This quietly elegant executive notebook is small, slim, sturdy and a dream to use. It's expensive, and its battery life is short, but it's one of the best business-travel companions we've seen.

ThinkPads have been a class act among business laptops since IBM launched the line over two decades ago. As a Lenovo brand, they remain pricey, but they’re also exceptionally easy to carry and comfortable to use. The ThinkPad X1 Carbon Touch stands out even from its forebears.

I recently took this Windows 8 Pro model with me on a flight from San Francisco to the East Coast and quickly fell into serious like with it. Fabricated from carbon fiber, it’s one of the thinnest and lightest 14-inch Ultrabooks around, and I found its low-glare touchscreen big enough to view spreadsheets without stressing my wrists and fingertips while panning and scrolling. The display was easy to read even in the constantly changing lighting conditions inside the aircraft’s cabin.

The wafer-thin ThinkPad X1 Carbon Touch weighs just 3.4 pounds.

The X1 Carbon Touch comes with other intelligent design elements, too: A perfectly tensioned screen panel that I could quickly flip open to the exact viewing angle I wanted; a quiet, cushy keyboard that’s a pure joy to type on; a large, smooth glass multitouch trackpad with excellent palm rejection to minimize fly-away cursors while I typed; and a case that’s tough and stiff, yet soft enough I could comfortably perch my palms on the keyboard deck for long stretches while I pounded out notes for this review.

I do have a few complaints. My biggest beef is the short battery life. I flipped open the X1 Carbon Touch soon after we lifted off from SFO, and it expired more than an hour from Boston. I’m used to getting to New England with juice to spare. I have a few other gripes, which I’ll mention later. All in all, though, the X1 Carbon Touch is a terrific machine. It’s one of the most comfortable and easiest-to-use notebooks I’ve laid eyes and hands on, and it’s amazingly tough for such a thin and light model.

If all you’re after is speed and feeds, you can find much of what the X1 Carbon Touch offers in machines costing hundreds of dollars less. Its most exciting silicon is the lightning-fast 180GB SSD that gave it the edge in our performance tests (more on that below). The processor (Intel’s 1.8GHz Core i5-3427U, with its HD Graphics 4000 integrated GPU) and the 4GB of memory are standard fare on small notebooks, and you can’t upgrade either.

ROBERT CARDIN

Not that you'll be playing a lot of games on the company's notebook, but it's good to know the X1 Carbon Touch can keep up with the competition on that metric. 

The Carbon Touch shines—truly shines—when you take it with you and actually use the thing. It’s so light and slim I hardly noticed it in my carry-on bag. It weighs only 3.4 pounds and measures 0.75 inches thick. Still, this ThinkPad hardly flexed at all when I gripped its ends with both hands and gave it the torque-twist test.

Getting down to business with the X1 Carbon Touch is an almost unbridled pleasure. The screen panel slightly overhangs the keyboard deck; that, plus the slightly tacky, almost rubbery case surface makes the laptop easy to grip and flip open, and it almost instantly wakes up from Sleep mode. Even from a dead start, the Carbon Touch fires up in 10 seconds, among the fastest full boots we’ve seen among little notebooks.

The 14-inch screen is based TN (twisted nematic) technology, so colors are less vivid, and viewing angles aren't as wide compared with an IPS (in-plane switching) display, but the viewing angles are exceptionally good for a TN panel, even from the top or the bottom. The screen resolution of 1600 by 900 pixels is a good match for the display’s size.

ROBERT CARDIN

You'd never guess that the X1 Carbon Touch's display is based on what's widely considered to be inferior twisted-nematic technology. 

And that brings me to input, one of this ThinkPad’s greatest strengths. You won’t find anything better on any computer this small. The display responds nimbly and accurately to touch gestures, and so does the touchpad. The keyboard is hands-down the best I’ve used on any notebook under 4 pounds. Lenovo spaced the keys an eighth-inch apart (only slightly less than the gaps you find on full-sized keyboards), the keys are slightly concave from side by side, they have the same slightly tacky surface you find on the case, and the tactile feedback is spot-on. The end result: I cranked out loads of typo-free copy even while wedged into my window seat on the 737. Plus, the keyboard is so quiet, it has almost no clacking sound to it at all.

This ThinkPad comes with two pointing devices: the eraser-head-like TrackPoint nestled within the keyboard keys, and the trackpad below the keyboard. The TrackPoint’s big benefit is that you don’t need to move your hands off the keyboard to use it. Touch-typists will love it, but I found the TrackPoint overly sensitive. Your mileage may vary. I could do multitouch gestures on it like pinching to zoom, so I didn’t have to move my hands up to the screen very often, and I worked blissfully free of flyaway pointer problems—the first notebook I’ve reviewed with that perfect record. The touchpad, though, is a little finicky when I tap on it to mimic left-mouse key actions.

Lenovo X1 Carbon Touch

Lenovo's Ultrabook delivered an excellent WorldBench 8.1 score. (Click charts to enlarge.)

The X1 Carbon Touch has some great usability features, such as the dedicated buttons underneath the screen for adjusting the volume and muting the onboard mic. These are very handy when making video calls. The speakers themselves are mounted near the front of the PC, beneath the keyboard deck. The bottom edges of the laptop slope up, so the sound bounces off whatever surface the computer is resting on. That’s fine if it’s a desktop or table, but it can sound muffled if the PC’s sitting on a soft surface like a seat cushion (although that’s not a good practice anyway, since that could block the cooling vent).

So where could Lenovo most improve this ThinkPad? Battery life and expandability. Our battery-rundown test puts battery life at 4 hours, 9 minutes, but it seemed even less in my day-to-day use. A saving grace: The battery recharges really fast. I charged it to 75 percent in 30 minutes, which is great even if you have tight flight connections.

Lenovo X1 Carbon Touch

Bring a portable battery charger with you on long trips. The X1 Carbon Touch's battery poops out much too early.

The X1 Carbon Touch also has fewer connections than I expect: just two USB ports (one 2.0 and one 3.0), a mini DisplayPort, an SD Card slot, and a headset/mic jack. You can use the USB 2.0 connector to charge a tablet or smartphone even when the computer is powered down. You get no ethernet port, so it’s good that Lenovo provides an ethernet dongle, but that’s something extra to remember to pack—and possibly lose. Lenovo also sells a VGA dongle for $35, if you really need one. I also found a SIM card slot on the back of the notebook for mobile broadband. But you’ll need to buy a 3G card and make sure that the needed WWAN (wireless wide-area network) antennas are installed inside the computer.

As is often the case with superthin notebooks, hardware upgrades are limited and a pain to accomplish. Your IT department might love the X1 Carbon Touch less than you. The Core i5 processor and the 4GB of memory, for example, are fixed. Apart from adding a WWAN card, you can bump up only the size of the SSD.

Lenovo X1 Carbon Touch

Not that you'll be playing a lot of games on the company's notebook, but it's good to know the X1 Carbon Touch can keep up with the competition on that metric. 

The X1 Carbon Touch performs quite well compared to its ultraportable peers. Thanks to its superfast SSD, it chalked up a 289 on our WorldBench 8.1 score, beating out nearly all its Core i5-based challengers and even some Core i7-based notebooks. As for real-time gaming, this ThinkPad plays them better than most small notebooks, but it’s still nothing to tweet about. Running BioShock Infinite at a resolution of just 1024 by 768 and with image quality set to low, the Carbon Touch delivered only 24 frames per second. That’s not awful, but it’s less than the 30 fps threshold you need to have a great experience.

You’ll want to keep the ThinkPad X1 Carbon's AC power brick close at hand, which will raise your carrying weight to 4.2 pounds. Apart from that and the too few connectors, it's a truly great notebook. It costs a pretty penny, and its performance won’t knock your argyle socks off, but it delivers enough power to cruise through all your typical business tasks, it’s tough as nails, and it’s an eminently easy machine to carry around and use. If you travel for work, those are the things that really matter.

Lenovo ThinkPad X1 Carbon Review: Exotic Case, Ho-Hum Screen

Lenovo is justifiably proud of its ThinkPad X1 Carbon ultraportable laptop. The machine is incredibly thin—just 0.7 inch at its thickest point—and the chassis is built with carbon fiber, resulting in an Ultrabook that ships with a 1600-by-900-pixel LCD display and weights slightly less 3 pounds.

In Search of Slim

In its zealous pursuit of ultrathinness, however, Lenovo did make a few compromises. Like the Asus Zenbook Prime UX31A and the Vizio C14-A2, the X1 Carbon has no built-in ethernet port, though Lenovo does include a USB-to-ethernet dongle. The X1 Carbon's LCD panel flexes enough to make me a little nervous, though a little flex won't hurt the display—and in fact may improve the laptop's resilience when dropped.

Port Minimus

Lenovo ThinkPad X1 Carbon There are other, stranger shortcomings. For example, Lenovo supplies a USB 3.0 connector on the right side of the X1 Carbon, but a USB 2.0 port—instead of another USB 3.0 port—on the left. At least the USB 2.0 port delivers enough current to charge a smartphone or other mobile device. The only video output is a mini-DisplayPort connector, and the lone audio jack is a combination input/output jack.

The Lenovo lacks a dedicated wired ethernet port, instead offering integrated 3G (not 4G) cellular broadband. According to Lenovo, the chipsets needed for PC 4G support would have taken up too much system board space and consumed too much power. You can use the integrated 3G as a mobile hotspot, if you need that capability.

Performance

Lenovo ThinkPad X1 CarbonThe ThinkPad X1 Carbon test model we tested includes an Intel Core i7-3667U CPU, with a default clock frequency of 2.0GHz and a maximum Turbo frequency of 3.2GHz. Like most Ultrabooks, this one uses Intel's HD 4000 integrated GPU and ships with 4GB of DDR3-1333 memory. A 256GB SanDisk solid-state drive handles storage chores.

In our performance testing overall, the X1 Carbon essentially tied with Vizio's C14-A2, despite having a faster CPU than the Vizio's Core i7 3517u. The Vizio outpaced the X1 Carbon in PCWorld's WorldBench 7 benchmark test suite, earning a mark of 158 as against the ThinkPad's score of 144.

On the power side, the X1 Carbon uses Lenovo's RapidCharge system, which allows the system to charge to 80 percent in just over 35 minutes. The system's measured battery life was a solid 6 hours, 11 minutes, almost an hour longer than the Vizio C14-A2's 5 hours, 17 minutes.

Not surprisingly, in view of the laptop's Intel HD 4000 GPU, the X1 Carbon's game performance was fairly weak. Even with detail settings at low, the Lenovo struggled to an unplayable 11.4 frames per second in Crysis 2, although its frame rate on the Dirt3 test was a more playable 36 fps.

Overall, Lenovo seems to have emphasized battery life over raw performance, a perfectly reasonable preference in designing an ultramobile PC.

Display and Audio

As usual with ultraportable laptops, audio quality in the ThinkPad X1 Carbon is limited. Lenovo did include Dolby Home Theater V4, which enhances the audio somewhat. Overall audio in music was neutral, but I could hear noticeable distortion in the speakers when volume levels were cranked too high. Though the X1 Carbon can't pump out sound at very loud volume, its speakers were definitely good enough for near-field use during travel.

The laptop's 14-inch LCD panel offers an excellent resolution of 1600 by 900 pixels. Text looked crisp, but colors tended to be muted and brightness levels were on the low side. On the other hand, the matte-finish screen picked up almost no glare from background lighting, which your eyes will surely appreciate.

Video playback quality tended to be somewhat disappointing, due in part to the relatively unsaturated colors and in part to the screen's limited viewing angles. Straight on, both high-definition and standard-definition content looked smooth, with little visible jerkiness or frame stuttering.

Usability

Lenovo includes both a TrackPoint stick-based pointing device and a large glass multitouch-enabled touchpad. The latter was a little too sensitive out of the box, but it does have good palm rejection, making for generally good cursor control.

The keyboard layout is good. The keys themselves are slightly indented and offer good tactile feedback, though keystroke travel is short. Lenovo also includes discrete page down and page up keys, a welcome addition to the usual Fn-key options.

Bottom Line

Lenovo put some serious thought into mobile usability with the ThinkPad X1 Carbon, including cellular broadband and the RapidCharge feature. The slightly flexible carbon-fiber chassis is an interesting departure from the rigidity of machined metal cases. Though Lnovo's failure to offer dual USB 3.0 ports and HDMI output is a little disappointing, the port selection isn't radically different from what similar superthin Ultrabooks provide. If you're a serious traveler, the X1 Carbon merits closer inspection.

ThinkPad X1 Carbon First Test Results: This Ultrabook Means Business

Like the ThinkPad X1 before it, the X1 Carbon is built for durability as it has passed 8 differe MIL-SPEC tests, including those which measure the ability to operate at extreme temperatures, altitudes and when being hit by sand. Like other ThinkPads, it has a roll-cage, but this time the cage is made from lightweight carbon fiber rather than magnesium. The X1 Carbon certainly felt durable in our testing as we were able to hold it by the deck with one hand, without feeling like the notebook would slip.

In order to make the X1 Carbon so thin, Lenovo has jettisoned several important ports. In particular the lack of an Ethernet connector will irk some business users. In many locations, wired Internet is much more reliable than wireless. Fortunately, Lenovo includes a USB-to-Ethernet dongle which solves this problem, as long as you remember to bring it along.

Ports on the ThinkPad X1 Carbon

The notebook is equipped with a mini DisplayPort for video out, a 4-in-1 card reader and an audio jack, but just two USB ports, only one of which is USB 3.0 compatible. Business users with older projectors will definitely miss having a VGA port. Despite the limited space, Lenovo somehow found room for a hardware Wi-Fi on/off switch, which just duplicates functionality that’s available in Windows already. We would have preferred a third USB port or Ethernet.

The X1 Carbon’s 1600 x 900, 14-inch matte display is truly stunning. Using our light meter this ThinkPad’s screen registered 290 lux, which is even brighter than the 1400 x 900 MacBook Air’s 268 lux mark. However, the ASUS ZenBook Prime and its 1920 x 1080 display returned a much stronger measurement of 423 lux.

ThinkPad X1 Carbon Screen

When we watched a 1080p QuickTime Trailer for SkyFall, images were sharp and detailed while colors were vibrant, though not quick as rich as on some other notebooks we’ve tested. Viewing angles were excellent; colors didn’t wash out at all, even at 90 degrees to the left or right.

The bottom-mounted speakers provided clean audio that was just loud enough to fill a small room at maximum volume. When we listened to both the bass-heavy “Forget Me Nots” and the guitar-laden “Basketcase,” sound was good quality was good enough to substitute for a low-grade stereo. Certainly, the Dolby v. 4 Home Theater software helped, particularly when we switched it into music mode. However, when we tried using the notebook on our lap, the speakers became just a little bit muffled.

The X1 Carbon’s island-style keyboard looks just like those on the recent ThinkPad T430 and W530, but it feels quite a bit shallower. Perhaps because the chassis is so much thinner, Lenovo had to sacrifice vertical key travel, which is a shame. Overall, we enjoyed typing on the keyboard and loved the feel of the comfortable, soft-touch palmrest under our wrists, but there is no doubt that it is not nearly as responsive as the keyboards on its thicker brethren. Even the MacBook Air’s keyboard seemed to have more depth and stronger feedback.

ThinkPad X1 Carbon Keyboard

As with other ThinkPads, the X1 carbon has two different pointing devices. The TrackPoint pointing stick is incredibly accurate and comfortable, just as it is on every other recent ThinkPad. We highly recommend the stick because it provides the most accurate means of navigating around the desktop and allows you to move your pointer without taking your fingers off of the homerow.

Those who prefer a touchpad will like the large 4 x 2.4-inch glass touchpad. Unlike Lenovo’s other touchpads, which recently have had textures, this pad has a completely smooth surface that feels so smooth that sometimes we found our finger sliding around a bit. However, the pad was incredibly accurate and, despite its integrated buttons, it displayed none of the jumpiness we’ve seen on some other clickpads. Multitouch gestures like pinch-to-zoom and three finger swipe were smooth, but two-finger rotate only worked some of the time.

The Thinkpad X1 Carbon stayed pleasantly cool throughout our tests. After streaming a video for 15 minutes, we measured the touchpad at 77 degrees, the keyboard at 85 degrees and the underside at 92 degrees Fahrenheit. We consider temperatures below 95 degrees comfortable.

With a 1.8-GHz Core i5-3427U under the hood and integrated graphics, the ThinkPad X1 Carbon is good enough for productivity tasks like crunching spreadsheets and transcoding videos. On PCMark 7, a benchmark that measures overall performance, the X1 Carbon scored a solid 5,297, well above the 2,854 Ultraportable average. This score also beats the 13-inch MacBook Air (4,380), which has the same CPU and the ZenBook Prime UX31A (4,989).

The 128GB SanDisk SSD booted into Windows 7 in a slow 56 seconds, 12 seconds behind the category average and way slower than ZenBook Prime (23 seconds) and the Fujitsu LifeBook U772 (27 seconds). The drive took a modest 1 minute to complete the LAPTOP File Transfer test, which involves copying 4.97GB of mixed-media files. That’s a rate of 84.8 MBps, which is about 50 percent faster than the 56 MBps category average, but slow for an SSD.

The SSD-powered MacBook Air completed the test at a rate of 159 MBps while the Fujitsu LifeBook U772 managed a rate of 121.2 MBps.

When it comes to perfoming productivity tasks, the ThinkPad X1 Carbon is no slouch. It took a mere 5 minutes and 37 seconds to complete the LAPTOP Spreadsheet Macro test, which involves matching 20,000 names with their addresses in OpenOffice calc. That time is significantly faster than the 8:08 category average, but still behind the 2.6-GHz Core i5-3320M-powered ThinkPad X230 (4:29) and the 1.9-GHz Core i7-powered ASUS ZenBook Prime (4:59).

Just forget about gaming on the ThinkPad X1 Carbon. With its integrated Intel HD 4000 graphics, it scored just 517 on 3DMark11, a synthetic graphics benchmark. That’s way below the 814 category average and the 624 offered by the MacBook Air.

When we tried playing World of Warcraft on the X1 Carbon, it managed a barely-playable 29 frames per second on autodetect settings and an unplayable 14 fps with the special effects turned up. Those rates are worse than the 46  / 23 fps category averages.

The ThinkPad X1 Carbon feels really good on our lap, it has an excellent screen, solid sound and accurate pointing devices. Though the keyboard doesn’t offer the level of feedback we expect from ThinkPads, it is one of the best Ultrabook keyboards around. What will really make or break this notebook is its battery life, which we have yet to test. Lenovo says to expect up to 7 hours of endurance, but our battery test tends to produce results that are below manufacturer’s claims. Stay tuned for our full rated review.
