Wi-Fi Performance
Although an office worker may use this device docked at their desk, there are certainly going to be many times where the wireless performance is important. Lenovo has included the Intel Dual Band Wireles-AC 7265 wireless adapter in the X1 Carbon. This is certainly a device that I have seen in a lot of samples, and it launched in Q3 of 2014, superseding the 7260 model. It offers 2x2:2 performance in both 2.4 and 5 GHz bands, and 802.11ac connectivity for a maximum of 866 Mbps assuming you have an 802.11ac router.
The X1 Carbon achieves about the same network performance as other devices with the Intel wireless card, coming in right around 400 Mbps. Although it cannot achieve the same performance as the Broadcom parts at the top of the list, I have found it to be a reliable card which connects without much issue. The first couple of devices I saw with this card did have a few connection issues, but they were both sorted out with driver updates. Since the X1 Carbon is newer, the driver installed worked well.
Speakers
The X1 Carbon has two downward firing speakers which are rated at 1 watt x 2. As always with devices this thin, expecting big performance out of the speakers is going to be quite a disappointment. Normally the biggest offender is the low frequency response, which is practically non-existent on notebooks.
The frequency response for the X1 Carbon was actually not too bad. The low end is, like all notebooks, pretty much not there, but the overall volume was very impressive. On several of the frequencies, the X1 Carbon would sustain over 100 dB(A) which is very loud. Playing the standard music track that I use to test speaker volume, I was able to hit around 87 dB(A) which is right up there with the loudest devices I have tested. The peak frequencies are all in the normal talking range, so this notebook would excel at voice conferences. It certainly does not lack volume.
Noise
Since this is a 15 watt CPU, it is going to require a fan in any sort of device that is this thin. However that does not mean it needs to be loud. A well designed laptop can keep the noise levels in check.
The X1 Carbon is one of those devices. When plugged in, there is a bit more fan noise with everything set from the factory since it chooses active cooling over passive, but it is quite reasonable. Unplugged, the device switches to passive to save power. On many workloads, the fans do not even need to kick in, but when they do, they start at right around 35 dB(A) measured an inch from the trackpad which is very quiet. The next step up is 38 dB(A) and the maximum noise seen on the X1 Carbon was around 41 dB. All in all, the noise output of the X1 Carbon is very reasonable. It is not fanless by any means, but when the fans do kick in, they start out very quiet and slowly move up to a level where they are never a bother.
Accessories
Since this is a ThinkPad, Lenovo needs to cater to the business crowd, and for many business users, much of their work day may be at a desk, but the portability of a laptop is needed for meetings or travel. The ThinkPad line has had docks for a long time, but the X1 Carbon is too thin to support the standard docking port.
To get around this, Lenovo offers a couple of docking solutions. Both connect to the power port of the X1 Carbon, which has a rubber cap installed on the right side. Remove the cap, and you gain full access to the docking port.
The first dock is the ThinkPad OneLink Adapter, which costs just $59.99. It is very basic though, with it just supporting power, Ethernet, and video, and it support PXE boot. It’s basic, but it gets the job done.
For those that need a more robust dock, there is also the OneLink Pro Dock, and it offers a lot more, but also costs a lot more at $179.99. There are four USB 3.0 ports, with one always powered in order to charge your phone, and there are also two USB 2.0 ports. DisplayPort and DVI are both available in order to run a couple of monitors, and it also has Gigabit Ethernet. The 90 watt AC Adapter keeps everything powered. The Pro Dock also has a headset jack.

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.Samus - Friday, May 22, 2015 - link
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.Daniel Egger - Thursday, May 21, 2015 - link
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.

Hi,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

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.Mumrik - Saturday, May 23, 2015 - link
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.
