In January of this year, I walked into the Lenovo booth at CES and almost immediately to the right there was a large display case set up, and inside was Eve. Eve looked great in the case all dressed in black, and was well attended to by her hosts. Eve is the one hundred millionth ThinkPad to be created, and I remarked at the time that it was likely not an accident that Eve is a ThinkPad X1 Carbon.

Eve, the 100,000,000th ThinkPad

The X1 Carbon has been Lenovo’s flagship ThinkPad since it was launched, and it brings the world of the ThinkPad business class notebook down into a much thinner and lighter form factor. Today we have the third generation of the X1 Carbon, and although the competition for the best Ultrabook keeps increasing, Lenovo brings a lot to the table with the X1 Carbon.

Lenovo keeps the ThinkPad lineup outfitted with features that the average consumer does not need, and the price is higher accordingly. But if you are someone who travels a lot, and needs a full featured notebook with all of the goodies, you can find it in this X1 Carbon. While the Ultrabook initiative started out with smaller devices, it gradually worked its way up to include larger notebooks as well, and the X1 Carbon certainly fits the bill for an Ultrabook despite the larger than average 14 inch display.

Despite the somewhat larger chassis, the X1 Carbon keeps the weight in check partially through the use of its namesake – carbon fiber. The display cover is created with carbon fiber reinforced plastic, and glass fiber reinforced plastic. This lets the display be lighter, thinner, and stronger than one made of aluminum or plastic alone. And it is strong. You can certainly flex the display, but it never feels like you are going to bend it by accident. The bottom of the X1 Carbon is made of aluminum and magnesium, so it is plenty strong as well. Lenovo even points out that the X1 Carbon has passed eight MilSpecs with fifteen individual tests, including shock, vibration, temperature, humidity, and silica dust exposure.

For many devices, 2015 is the year of the spec bump to Broadwell based processors, and Lenovo is not immune to this. Luckily that is a good thing though, and the new X1 Carbon is now powered by the latest Broadwell-U based processors from Intel. Buyers get a choice of the i5-5200U, i5-5300U, or the i7-5600U processor. None of these are slow, but luckily Lenovo has sent us the i7 model so we can get a feel for how it competes against some of the other Broadwell devices we have seen this year. Let’s take a look at the full specifications below.

Since this device falls into the ThinkPad line, you get a lot of customization options when purchasing that Lenovo does not do for their consumer models, and that is very welcome because on a lot of devices if you want feature X you have to also buy features Y and Z, which can really bump up the costs. However a few things need to be called out on the X1 Carbon. This is a premium Ultrabook, so it is a bit sad that in 2015 the base model is still offered with just 4 GB of memory, and because this is soldered on (like all of these very thin devices) it would be money well spent to just add the extra $75 Lenovo charges for the 8 GB model. Luckily even though Lenovo calls it 1x8 GB in the guide, it is in fact dual-channel memory. The other big complaint is the 1080p model is offered with a TN panel. That is not really acceptable in a $1000+ device in 2015 any longer. Moving to the QHD version of the panel for $150 would be money well spent since that will bring you an IPS panel.

There are also a lot of options for storage, and the base model comes with just a scant 128 GB of SSD space available, but for not too much more you can bump that up to 180 or 256 GB. For those that need even more storage space and speed, Lenovo offers the SM951 equipped 512 GB PCIe based Samsung SSD. When the X1 first launched, it was a hefty $700 upgrade, but now it is a mere $425 over the base 128 GB offering.

The X1 Carbon is even offered with optional LTE connectivity, via the Sierra EM7345, for those that need mobile data connectivity without tethering.

    Samus, Lenovo used the IBM logo on T60 an T61 even though they weren't IBM anymore. Probably because the chassis was built in the same machines and according to the same plans and they had the shape cut out for the IBM logo. In 2007 the T61/p were being built also without the IBM logo and used a ThinkPad logo. But that was it. T61 had the last of the IBM logos in 2007.

    I understand and agree with you. It's CasualUker that seems to think there are IBM "imprints" on the T430's. LOL.
  • close - Friday, May 22, 2015 - link

    CasualUker: the last one IBM made under their own name was the T43/T43p. T60 was already a Lenovo affair. Ok, they were probably riding on a lot of IBM knowhow, designs and everything but to be honest it was all downhill from there. I'm not saying they're the worst, they're still among the OK ones, just that the general level of quality and reliability has constantly dropped.
    I have a running T43. It's 2015 and it's still running. I had two R31 and R32 that ran until a few years ago. Also a running X200 (3 generations after lenovo took over). Had some issues but still running. After that I couldn't get a laptop to run fine for more than 3 years. And I work in a company that buys thousands of Lenovos X, T and W every year, generation after generation. Reliability is down. I have no expectations from a ThinkPad anymore.

    I have to agree. Thinkpads were brilliant laptops when IBM owned the brand. I had a T20 for years. Our company started using the T440s about a year ago. I'm on my second laptop after the MB failed on the first one, and my touchscreen has stopped working. I'm going BYOD with a Surface Pro 4 as soon as it's available.

    Totally agree, I've had IBM Thinkpads for many years before I move everything to Apple. A couple of years ago I made the horrible mistake to buy a Lenovo Thinkpad; unusable trackpad and trackpoint is often erratic, soft controlled radio functions sometimes can be activated and other times needed a reboot, locked down BIOS to only support Lenovo branded cards in the two mini-PCIe slots, screen easily cracks due to bogus frame and design and claims from Lenovo that a laptop is not made to be transported around -- service is horrible as well.

    Nowadays I see them for what they are: always the cheapest and as usual you get what you pay for...

    For the enterprise, their service has been pretty great.
    Very fast response times, and prompt deliveries (had to replace a keyboard and battery, but for two different lappys).
    I do wish they'd up their quality, though, b/c, as you say, aspects of their assembly leave room to be desired.
    For linux support, however, they are the only real option. Yeah, you can hack it onto a mac (lots of folks do), but you're at the mercy of mathew garrett to fix the issues at that point.

    Lenovo apologist here - we've bought over around a hundred or so Thinkpad units since late 2007, and have yet to retire one. There were only two that needed a repair (under warranty), and the only other issues we have had til date have been due to keys ravaged or physical damage.

    Also, LOL @ the guy citing some guy's IT business closing down because of poor Lenovo service
  • Samus - Friday, May 22, 2015 - link

    Do a quick google search into corporate fallout from Superfish before you "LOL" a lot of people irrationally overreacted costing a lot of IT departments their jobs for "putting companies in danger."

    It was utterly ridiculous, but not really surprising considering how unprofessional of an organization Lenovo is. They are a consumer company, not an enterprise company. Think Ideapad, not Thinkpad. Huge difference. The fact they created the unholy offspring Thinkpad E-series to replace the budget R-series (the E-series is Ideapad internals) then created the joke that is the X100 series that have literally no Thinkpad technologies (Thinklight, Trackpoint, TPM, magnesium...) just goes to show Lenovo is willing to sell anything at any price in any disguise.

    agree - worst customer service. tons of problems. tons of costs. i am switching to apple.

    My mother buys herself a new Thinkpad every year through her company. Through 4-6 years she has yet to have one last the whole year without the battery, keyboard or pointing device (last year of course) breaking down.
