Lenovo ThinkBook 14 Review: Business Laptop with Great Connectivity

Sebastian Bade, 👁 Andreas Osthoff, Felicitas Krohn (translated by Finn D. Boerne), 03/03/2020

Modern subnotebook with lots of ports! Lenovo's ThinkBooks are aimed primarily at business users. They lack most of the ThinkPad series' numerous business features but should still perform adequately nevertheless. Find out in our review how well the new subnotebook did, and what its pros and cons are.

Lenovo’s ThinkBook series is supposed to fill the gap between the consumer-oriented IdeaPad line and the business-centric ThinkPads, and as such it is aimed primarily at business users looking for a durable and long-lasting device for everyday use. The Lenovo ThinkPad 14 is a compact office laptop with modern connectivity. It features Intel’s Comet Lake Core i5-10210U, 8 GB of RAM, and a fast 256 GB NVMe SSD. All of that can be had for less than $800.

Case and Connectivity – Rigid and with Great Connectivity

Visually, the ThinkBook 14 comes in a rather discreet gray case without too many bells and whistles. The choice of material is well thought out, and both base and display lid are made of aluminum, providing additional structural support. We were practically unable to warp and twist the case, and you will need a significant amount of force to depress the base or lid. The latter is particularly good at absorbing localized forces thereby avoiding the dreaded ripple effect on the display. The only parts made of plastic are the black bezels around the display. The hinges do a great job of keeping the display firmly in place and offer a maximum opening angle of 180 degrees. Teetering is reduced to an absolute minimum.

All things considered the ThinkBook 14 is very compact, as can be seen in our size comparison. Our review unit offered the smallest footprint in our test group. With its weight of 1.6 kg it can be found in the middle of the pack. Of particular note is the laptop’s connectivity as it offers a total of five USB ports, two of which are future-proof USB-C ports. The card reader is connected to the USB 3 bus, and it was able to outperform its competitors slightly when benchmarked with our 64 GB Toshiba Exceria Pro SDXC UHS-II reference card. Intel’s Wireless-AC 9560 played nicely with our Netgear Nighthawk RAX120 router, and the laptop also supports wired connectivity.

Input Devices

The ThinkBook 14 comes with a chiclet keyboard but lacks a dedicated numpad due to space constraints. The keyboard looks very clean and straightforward overall, and the keycaps are comfortably large and slightly roughened for improved grip. Key travel is fairly short and bottoms out in a very well-pronounced key pressure point. Unfortunately, Lenovo did not include a keyboard backlight, which would have improved readability in the dark.

We have already encountered this particular ClickPad on the Lenovo ThinkBook 15, and our smaller 14-inch notebook is equipped with the exact same model. At 10.5 x 7.1 cm (4.0 x 2.8 inches) it is sufficiently large for comfortable multi-touch input. The buttons located at the bottom edge offer a discreet clicking sensation.

Our ThinkBook 14 SKU came equipped with a matte 14-inch IPS panel with FHD resolution and a pixel density of 157 ppi. According to the spec sheet a Full HD TN panel is also available, albeit with lower maximum brightness and contrast ratio.

Speaking of which, our review unit only managed a meager 232 nits, and thus failed to achieve its advertised brightness of 250 nits. Its contrast ratio of 267:1 was just as bad due to the combination of low brightness and a very high black point. We could not believe how bad it was and repeated our tests and measurements several times to no avail. Display brightness regulation is achieved through PWM, fortunately at a very high frequency. It should thus not cause any issues even in sensitive users. Minor clouding was visible in dark scenes.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms rise
↘ 12.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 19.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 25000 Hz ≤ 60 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 60 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17067 (minimum: 5 - maximum: 2500000) Hz was measured.

vs. AdobeRGB (40.9%)

Despite its low contrast ratio, the ThinkBook 14’s display offered a decent image quality in day-to-day situations. We strongly advise you to use our ICC profile in order to lower DeltaE 2000 deviations from their very high out-of-the-box levels as we were particularly successful in improving grayscale accuracy after calibrating the display with an X-Rite i1 Pro 2 spectrophotometer and CalMAN. Colors were only improved slightly, which further shows that the display is at its limits as-is already. Color-space coverage is another sore point, although we should note that at 63.7% sRGB and 40.9% AdobeRGB our review unit did manage to outclass its competitors.

Outdoor usability is limited at best due to its poor display brightness, which is too low to overpower sunlight. We did not encounter any issues in shady spots, though. Viewing angles were also not as wide as expected. When looked at from all four corners we noticed some minor color tint.

Performance – Fast Enough for Most Users

The Lenovo ThinkBook 14 was more than fast enough for everyday office life, and the combination of a modern Comet Lake CPU and the rest of its hardware worked great. We did not encounter any DPC latency issues. Intel’s Core i5-10210U should be fast enough for most users.

Processor

The Core i5-10210U's TDP is configured at 15 W, but the CPU is allowed to consume up to 38 W for short bursts of load. The ThinkBook 14 outclassed its entire competition and consequently placed first in our benchmark. It was also slightly faster than the average for this particular CPU.

The Core i5-10210U’s overall performance was good. When running our Cinebench R15 multithread loop the ThinkBook 14’s performance dropped slightly after the first run but remained consistent afterwards for a while until it dropped even further, this time more notably.

More details and benchmarks can be found on our CPU comparison page.

System Performance

Thanks to the Intel Core i5-10210U's good overall performance the ThinkBook 14 performed very well in our system performance benchmarks. Most of the time our review unit placed first, and it only had to succumb to the Dell Latitude 3400 once. Our subjective impressions further confirmed these benchmark results.

GPU Performance

As is the case with all Comet Lake CPUs the integrated GPU is Intel’s UHD Graphics 620. However, the ThinkBook 14 can also be equipped with a dedicated AMD Radeon 620 according to Lenovo’s spec sheet, and we did notice a free solder socket on the motherboard. In our test, the ThinkBook 14 was unable to keep up with its AMD Ryzen 5 and Ryzen 7-equipped rivals as AMD’s integrated Radeon RX Vega GPUs are simply out of Intel’s league when it comes to 3D performance. Particularly so given that Lenovo failed to fully utilize the iGPU’s full performance potential due to our review unit’s single-channel RAM interface. Games can only be played in very low resolutions and on minimum details.

3DMark 11 after our stress test

Under load, the case temperatures peaked at 45.9 °C, which is okay overall. After encountering the very quiet fan we did expect higher temperatures to be honest.

Maximum CPU temperature under full load was measured at 88 °C. This maximum was reached very quickly into the load test while the CPU was still capable of running at its maximum turbo boost speeds. Afterwards, the Intel Core i5-10210U's temperatures settled at between 67 °C and 71 °C. As such it remained cool enough to avoid any thermal throttling issues, and accordingly the CPU ran at 2.6 GHz and thus a full GHz faster than its base clock speed of 1.6 GHz.

Power Consumption

65 W power supply

When taking our usual power consumption measurements, we were positively surprised by the ThinkBook 14’s low overall power demands. Under load, it peaked at 62.2 W while the CPU was still able to run at its maximum turbo boost speed. Once it settled down, power consumption decreased to just 43.3 W. The 65 W power supply is thus more than amply dimensioned. Just like its bigger brother, the ThinkBook 15, the ThinkBook 14 can be charged via USB-C.

Verdict – Well-Equipped Office Device

In review: Lenovo ThinkBook 14. Test unit courtesy of Cyberport

The Lenovo ThinkBook 14 is a solid office device for business users, and the subnotebook is also very well-suited for everyday office tasks at home. In addition, at its low price of less than $800 it does not leave too big of a hole in your wallet. In return, you get a well-built high-quality device made of well-chosen materials. We also liked its plentiful connectivity, including the card reader which, more often than not, is missing on modern laptops.

In terms of performance the Lenovo ThinkBook 14 offered an overall good experience. Its Core i5-10210U is a great fit and offers more than enough performance. Its 8 GB of soldered RAM was neither here nor there, and it can be retroactively upgraded by adding a secondary module. Storage space was somewhat limited due to the 256 GB SSD but this, too, can be retroactively upgraded to fit your needs. In other words: You do not need to consider future requirements at the time of purchase just yet and might be able to save quite a bit of money in the long run.

Lenovo’s ThinkBook 14 offers good performance and long battery life at a comparatively low price.

Our biggest point of concern is the display, as it failed to meet its advertised specifications. The differences were much more pronounced than can be expected owing to manufacturing tolerance. We sincerely hope that our review unit was an extreme case with a particularly bad display unit.
