Lenovo Thinkpad X1 Carbon (2017) Review

The best ultrabook lenovo thinkpad

The fifth generation of Lenovo’s Thinkpad X1 Carbon is currently the best Ultrabook

If there is a notebook series that fits the term “timeless” like no other, then this is Lenovo’s ThinkPad series. For 25 years now, these dinosaurs of computer history have been standing for solid business devices whose quality is often worth a handsome purchase price for many corporate customers. Already in the fifth generation, the X1 Carbon has been released this year. Last year’s model was already one of the most compact and lightest business notebooks ever, but Lenovo’s 2017 model once again tops the list.

Flawless processing

Robust and reliable and yet light, these are the most important characteristics of a ThinkPad. Lenovo continues to use a hybrid magnesium alloy for the base unit. The haptics with the smooth surfaces is practical because it makes the device particularly handy. It’s pretty unlikely to slip out of your hand. Everything is extremely strong and stiff, even with a lot of pressure we can only push the keyboard area down to a minimum. What we also notice about X1 Carbon: It is ultra-lightweight – the ThinkPad weighs 1.13 kilograms and is extremely flat with a height of 15.95 mm.


As with its predecessor, Lenovo ThinkPad X1, Carbon 2017 uses a matt 14-inch display and relies on IPS technology with a high resolution of 2,560 x 1,440 pixels or 1920 x 1080 pixels. The average brightness is slightly lower at just under 290 cd/m². However, it could have been a bit brighter, as this compact device will also be used outside the office.

The X1 is available in four processor versions (2x Intel Core i5 and 2x Intel Core i7, seventh generation), which are now even found in 15-inch business notebooks. Especially in combination with the solid state disks, this results in a powerful and above all fast-reacting working device for everyday office use. Depending on the configuration, either 8 or 16 GB LPDDR3 RAM (dual channel) is available. Lenovo does not offer dedicated optional graphics cards, so the graphics output is handled by the processor’s built-in GPU. The X1 Carbon is available in four processor versions – 2x Intel Core i5 and 2x Intel Core i7, the seventh generation of the Kaby-Lake, 8 or 16 GB RAM and SSD memory sizes from 128 GB to 1 TB. The graphics chipset is not a calculating monster with the Intel HD Graphics 620, which is not expected with a business notebook.

Connections & Stereo

In the back of the left side, there are now two USB-C connectors with Thunderbolt support. There are two more USB 3.0 ports, a full HDMI port, and a mini network connector. In addition to the cabled Gigabit Ethernet connection, Lenovo is also equipping the ThinkPad X1 Carbon with WLAN modules from Intel, such as the M. 2 card Dual-Band Wireless-AC 8265. The two stereo loudspeakers leave a good impression, even though there is hardly any bass available due to their design. In movies or music, the sound is, therefore, a little thin. With 57 watt-hours, the capacity of the lithium polymer module 3-cell battery has increased and the operating time is 15.5 hours. Thanks to rapid-charge technology, the X1 is charged to almost the highest battery capacity in 60 minutes.


With the new ThinkPad X1 Carbon, Lenovo offers an extremely high-quality and very well-manufactured business notebook. The focus here is clearly on mobility because, with just over 1.1 kg, the 14-inch device is extremely mobile.
