Lenovo ThinkPad X1 Carbon (4th Gen) 20FB005WUS ultrabook Review

% Very Good

The Lenovo ThinkPad X1 Carbon 20FB005WUS ultrabook See at Amazon is the 4th generation of the ThinkPad X1 Carbon now in the market. It all started with the E460, L460, T460, T460p, T460s, and now the X1 Carbon with its different generation. The Lenovo ThinkPad X1 Carbon 20FB005WUS now sports a notable improvement in size and weight from the already thin and lightweight 3rd generation ThinkPad X1 Carbon. Also the Lenovo ThinkPad T460s See at Amazon is thin and lightweight and it brings a good fight to the table. As a result we focus on what improvements the ThinkPad X1 Carbon made against the ThinkPad T460 series.

The Lenovo ThinkPad X1 Carbon 20FB005WUS ultrabook See at Amazon doesn’t mince words when it comes to business prowess. It features all the required recipes for an industry leading business companion: a durable carbon fiber design, long battery life, portability and stunning WQHD display (for our reviewed configuration) to go with. The X1 Carbon built well on the weakness of the Lenovo ThinkPad T460s See at Amazon and we recommend it as a value for money business laptop.


What makes the Lenovo ThinkPad X1 Carbon 20FB005WUS See at Amazon stand out from other previous versions isn’t just the material used. Lenovo still used carbon fiber and magnesium body to bring this laptop together; a splendid work of art still right there. What really makes it stand out is the thinner and lighter body which is far much sleeker than last year’s. The frame has an appealing glow and smooth textured touch for better gripping. A notable improvement to this X1 Carbon generation, is that it fits right into my palm thanks to its 0.65 inches. It measures 0.65 by 13.1 by 9.0 inches (HWD) and weighs 2.54 pounds.

We were also glad that the frame also went through Lenovo’s system’s hardy certification. I’m talking about the MIL-STD 801G test which involves tests against: humidity, low temperature, high temperature, high altitude, dust, blowing sand and temperature shock. The test is rather comprehensive and brings out a good durability scale that shows how well the laptop is built to brave the elements.

Our reviewed unit of the X1 Carbon is adorned with a 2,560 by 1,440 (WQHD+) resolution display but there is a Full HD (1920 x 1080) display available. WQHD promises stunning photos and high resolution video especially while streaming 1080p YouTube videos. Both displays are based on the IPS panel which means they have great viewing angles. The screen brightness on our WQHD model hit 267 cd/m rather than the promised 300 cd/m which is slightly lower than the HP EliteBook Folio P0B88UT#ABA 12.5″ Laptop (Silver) See at Amazon. The hinges also allow the X1 carbon to tilt as far back as 180 degrees so you won’t have a problem finding a suitable working position.


The Lenovo ThinkPad X1 Carbon 20FB005WUS houses a number ports even with a thin body. There are three USB 3.0 ports among others and should you need more port options, the OneLink port allows a fully fledged docking station (In this case the Lenovo OneLink+ Dock).

The left side is home to the power adapter, OneLink+, Mini DisplayPort and USB 3.0. The right hand has the headset jack two USB 3.0 ports, a HDMI port and finally the Kensington lock for security. The microSD slot and SIM slot (for the optional 4G LTE modem) are both found at the rear right next to the fan control.

For other connectivity options, the Lenovo ThinkPad X1 Carbon 20FB005WUS has Intel’s current Wireless-AC 8260 adapter which supports WLAN standards 802.11a/b/g/n/ac. There is the Bluetooth 4.2 that worked hand in hand with that (has transfer speeds of 50 MB/s which is much lower than the ThinkPad T460s 70MB/s).

For video calls, there is a webcam above the display with 1280 x 720 resolution. The image on this webcam is poor and blurry but sadly so is the competition’s. Fortunately, the microphone is pretty high quality.

Thinkpad X1 Carbon 4th generation Performance

The X1 Carbon comes with 2015’s groundbreaking 2.6 GHz Intel Core i7 6600U processor. It is a great Skylake architecture processor with overclock speeds of 3.1 GHz. That works beautifully with the 8 GB DDR4 RAM and integrated Intel Graphics 520 GPU. This system performance is neck to neck with the high-end Core i7-6600U T460s model. The processor enables multitasking and demanding applications, not mentioning handling most of your ordinary office and multimedia tasks.

Additionally, there is 256GB Solid-state drive that comes in handy for data storage. For users working on demanding simulations and complex software, we recommend the Lenovo ThinkPad T460p See at Amazon. It should be able to provide a reliable quad-core processor capable of handling such intensity.

Not much about the GPU will put a smile on an avid gamer’s face. HD Graphics 520 is on most scales too slow to handle current AAA games. But that doesn’t cancel out 2-3 year old games which run smoothly on low settings. I won’t bash Lenovo for that because gaming isn’t the laptop’s goal and not as many people play games on their work laptop.

Lenovo includes the Windows 10 operating system pre-installed in the drive. Besides that, there are a few other apps like the Dolby Audio, McAfee LiveSafe and a personally useful link to download Microsoft Office. Fortunately, we found no bloatware pre-installed which is awesome.

As much as noise is concerned, the X1 Carbon is silent while on idle and daily tasks. The installed SSD storage enables quiet performance and the smooth working fans ensure that things as they are.


The keyboard is almost perfect especially for churning out long emails and texts. While the 14 inch laptop keyboard doesn’t include a number-pad to go with, it counters that with comfortable 3mm travel keys. The keys are wonderful thanks to the curvy design that accommodates your fingers and they click with a silent snap. The backlit keyboard also made a remarkable impression on us. It illuminates the chiclet –style keys bright enough so you don’t have to worry about late night typing.

The bio-metric finger-print reader sits on the right side of the wrist rest, well positioned for your thumb or index finger login details. For security, the reader also works in tandem with the system’s TPM chip.


The battery life is the one aspect that truly sets the Lenovo ThinkPad X1 Carbon 20FB005WUS up as a leading business laptop. In the rundown test, it managed a remarkable 10 hours 7 minutes. Well, Lenovo promises up to 11 hours but we if can go way beyond that under optimal conditions; minimum brightness and no backlighting. The X1 Carbon also comes with a neat support feature, the ‘RapidCharge’ that allows the battery to fast charge from 0 to 80 percent within an hour.
