Lenovo ThinkPad X1 Carbon 6th Gen review: A peerless business ultraportable

  • Editors' rating
    9.0 Outstanding


  • Compact, light, solid build
  • Excellent keyboard
  • 8th-generation Intel Core processors
  • Screen option with Dolby Vision HDR
  • ThinkShutter privacy cover for camera


  • Disappointing speakers
  • No reduction in size and weight from previous generation
  • Noticeable screen bezels
  • Expensive

Lenovo's flagship 14-inch ThinkPad X1 Carbon is now on its 6th generation. It heads up the company's range of business laptops, along with two newer kids on the X1 block: the convertible ThinkPad X1 Yoga 3rd Gen and the detachable ThinkPad X1 Tablet 3rd Gen. All three devices share the robust build and top-end specifications that underpin the ThinkPad X1's reputation.

Lenovo's aim with the 6th-generation X1 Carbon is to build on what's gone before rather than trying anything new. What we have here is refinement rather than revolution -- expensive refinement, too, with a starting price of £1,439.99 (inc. VAT; £1,199.99 ex. VAT, or $1,215.20 in the US).


The 14-inch ThinkPad X1 Carbon 6th Gen runs on 8th-generation Intel Core processors with up to 16GB of RAM and up to 1TB of SSD storage. It weighs from 1.13kg and runs for up to 15 hours on battery power, according to Lenovo.

There are differences from last year's model, but they are few and subtle. So, on the lid we have the red and black X1 marque in addition to the traditional ThinkPad logo with the red dot over the 'i' that illuminates under certain conditions. And on the inside, Lenovo has added its ThinkShutter privacy cover to the camera. This is also found on the ThinkPad X1 Yoga (3rd Gen) and a 'lesser' model, the ThinkPad T480s (but not the ThinkPad X1 Tablet 3rd Gen). The shutter slides over the camera easily -- provided you have sufficient fingernail to slot into a groove. Nail-biters might have problems.

Elsewhere it's business as usual. The black chassis has a rubberised finish top and bottom that helps hold the laptop steady on a desk and prevents it slipping around in the hand. Carbon fibre keeps the chassis solid, and while there's some flex in the lid it's not enough to create concern about carrying this laptop around without a protective sleeve.

There's no change in overall size and weight, this year's model shows no change from last year -- the big change came between 2016 and 2017 when the overall footprint was reduced by 10 percent, and weight dropped very slightly:

Model Year Dimensions Weight
ThinkPad X1 Carbon 6th Gen 2018 323.5mm x 217.1mm x 15.95mm 1.13kg
ThinkPad X1 Carbon 5th Gen 2017 323.5mm x 217.1mm x 15.95mm 1.13kg
ThinkPad X1 Carbon 4th Gen 2016 333mm x 229mm x 16.4mm 1.21kg

It's a pity Lenovo didn't lose a little girth this time round, and/or create smaller screen bezels. As it is, the 14-inch screen has side bezels of 5mm, an upper bezel of 12mm and a lower bezel of 19mm. This isn't likely to be a deal-breaker, but if Lenovo were to make any concessions to fashion this year, it should have been here.

This is not a convertible laptop -- for that feature, look to the ThinkPad X1 Yoga 3rd Gen. The furthest the X1 Carbon's screen will go is flat to the desktop.

The 14-inch IPS screen has options for 2,560-by-1,440 and 1,920-by-1,080 resolutions, and for touch and non-touch versions, although no preconfigured touch models are available on Lenovo's UK website (see below). Three of the four off-the-shelf screen options have anti-glare screens, but my review sample had the glossy version. This is the only option with Dolby Vision, which offers 500-nit brightness and a wide colour gamut.

The screen options are:

Screen Reflectivity Resolution Brightness
14-inch IPS HDR WQHD (+ Dolby Vision) glossy 2560 x 1440 500 nits
14-inch IPS WQHD anti-glare 2560 x 1440 300 nits
14-inch IPS FHD anti-glare 1920 x 1080 300 nits
14-inch IPS FHD anti-glare 1920 x 1080 300 nits

It's no surprise that the keyboard is among the X1 Carbon 6th Gen's best features.

The keyboard is a typical ThinkPad unit. The pot-bellied main keys require the very lightest of touches, and are extremely comfortable to use at speed for long periods. Lenovo's signature TrackPoint sits between the G, H and B keys, and is smooth and comfortable to use. Two physical buttons and a scroll button sit beneath the space bar, for use with the TrackPoint. NFC is integrated into the TrackPad, and there's a fingerprint reader to its right, in the wrist-rest area.

The big upscale on the ThinkPad X1 Carbon 6th Gen is the move to 8th-generation Intel processors across the preconfigured range, whose prices span from £1,439.99 up to an eye-watering £2,605.59 (inc. VAT). My review sample was not one of the off-the-shelf models: it had an Intel Core i7-8550U processor, 16GB of RAM, a 2,560-by-1,440 glossy non-touch screen, and 512GB of solid-state storage.

The preconfigured models are:

  • Intel Core i5-8250U, Windows 10 Home, 14.0-inch 1,920 x 1,080 non-touch anti-glare screen, Intel UHD Graphics 620, 8GB RAM, 256GB SSD
    £1,439.99 (inc. VAT)
  • Intel Core i5-8250U, Windows 10 Pro, 14.0-inch 1,920 x 1,080 non-touch anti-glare screen, Intel UHD Graphics 620, 8GB RAM, 256GB SSD
    £1,449.99 (inc. VAT)
  • Intel Core i7-8550U, Windows 10 Pro, 14.0-inch 1,920 x 1,080 non-touch anti-glare screen, Intel UHD Graphics 620, 8GB RAM, 256GB SSD
    £1,629.99 (inc. VAT)
  • Intel Core i7-8550U, Windows 10 Pro, 14.0-inch 2,560 x 1,440 non-touch anti-glare screen, Intel UHD Graphics 620, 8GB RAM, 512GB SSD
    £1,879.99 (inc. VAT)
  • Intel Core i7-8650U, Windows 10 Pro, 14.0-inch 2,560 x 1,440 non-touch glossy screen with Dolby Vision, Intel UHD Graphics 620, 16GB RAM, 1TB SSD
    £2,605.59 (inc. VAT)

There's a fair range of connections, including a pair of USB-C Thunderbolt ports (one of which will be occupied during charging), a flash card reader, a headset jack and, for those taking the LTE mobile broadband option, a SIM slot. The flash card reader, which only reads MicroSD, sits behind the covered SIM slot on the back of the chassis. and is a hassle to access if all you want to do is copy a couple of photos.

Two USB 3.0 ports and a full size HDMI connector should keep those with older peripherals happy. However, unlike Fujitsu, Lenovo has been unable to integrate wired Ethernet (see my photos of the pop-out Ethernet connector on the Lifebook U938 for example), instead providing a dongle. There's no VGA, which Fujitsu has included on several laptops recently, including its twisting 2-in-1 Lifebook T938.

The speakers are the least impressive aspect of the ThinkPad X1 Carbon 6th Gen. Tinny even at lower volumes, they will just about do for video calls, but you'll be better off with a headset or external speakers.

Lenovo claims up to 15 hours for the X1 Carbon's 57Wh Li-polymer battery, but that seems a little optimistic. With my normal workload of writing, streaming and web research, for example, I tended to deplete a fully charged battery by 50 percent after around five and a quarter hours -- that is, about two-thirds of the way through an eight-hour working day. That means it's probably good enough for a day's work unless you're a power user. RapidCharge support means you'll be able to boost the battery to 80 percent capacity in an hour, if required.

Lenovo has done little more with the ThinkPad X1 Carbon 6th Gen than keep it up to date with processor and screen upgrades. It would have been good to see some size and/or weight shaved off, and for the screen bezels to slim down. It's also time to think about improving the speakers.

However, as with its predecessors, the X1 Carbon's tough chassis and excellent keyboard are standout features, while all-day battery life should be possible for all but the most demanding power users.
