Verdict

Lenovo's Chromebook Plus 14 (14M9610) has a lot to offer. With its brand-new MediaTek Kompanio Ultra 910, it offers long-lasting battery life and top-notch application performance.

Four speakers provide clear and rich audio playback, while a bright OLED screen delivers brilliant colors. Modern features and a sturdy chassis complete the favourable impression. On the downside, the display's glossy surface causes distracting reflections that make it difficult to use in bright environments, and the case gets noticeably warm under sustained heavy load.

Pros

+ excellent MediaTek Kompanio Ultra performance
+ excellent battery life
+ good sound from four speakers
+ completely silent thanks to passive cooling
+ high-quality and slim chassis

Cons

- gets noticeably warm on the bottom under heavy load
- highly reflective screen
- ARM architecture can cause limitations with specific Linux apps
- keyboard and palm rest attract fingerprints

Case & Connectivity

Though it has a plastic bottom plate with a textured pattern, the chassis of the Lenovo Chromebook Plus 14 is mostly aluminum and glass. The silver design looks premium, although a noticeable bump on the display lid houses the 5-megapixel webcam and a mechanical privacy shutter.

The chromebook comes equipped with the latest Wi-Fi 7 standard for the fastest possible wireless connections. The port selection is practical for everyday use, offering two USB-C ports, a USB-A port, and an audio jack to cover the most important needs. Additionally, a fingerprint sensor provides quick, password-free logins.

Sustainability

When it comes to sustainability, the Chromebook presents a mostly positive story, though with some room for improvement in transparency. While Lenovo hasn't published a detailed Product Carbon Footprint (PCF) report for this model yet, the device has earned a TCO certification, which estimates its manufacturing carbon footprint at around 237 kg of CO₂.

A major win for sustainability is its fanless design, made possible by the highly efficient ARM processor. This passive cooling approach is great for users, as it means the device is always completely silent and it also simplifies long-term maintenance, since there are no fans to attract dust or require cleaning. Taking this a step further, Lenovo encourages repairs by providing detailed guides on its support site, even placing convenient QR codes on and inside the chassis that link directly to the instructions.

A look inside the Chromebook 14 reveals more QR codes that offer instant access to official maintenance guides.

Input Devices

For those lengthy periods of writing, this keyboard is ideal because of its comfortable, well-defined typing feel, adjustable backlight, and sleek design. However, the gray surface of the keycaps is quite susceptible to fingerprints, which can detract from the otherwise clean overall impression.

Below the keyboard is an adequately sized touchpad that responds precisely to inputs. The controls are supplemented by a responsive touchscreen that allows for fluid and intuitive navigation through ChromeOS.

Display

A standout feature of the Chromebook is its 14-inch screen. With a Full HD resolution (1920 x 1200 pixels) in a 16:10 aspect ratio, it pass on all content crisply. However, its real strength lies in the OLED technology with its great color rendering. The panel is also HDR 500 True Black certified, which promises a particularly dynamic and vibrant picture with compatible content.

Our measurements confirm excellent color reproduction. The sRGB color space, which is crucial for web-based work on ChromeOS, is covered completely at 100%. With a Delta E 2000 of just 1.65, color deviations are barely perceptible. The advertised peak brightness of 400 cd/m² was not quite reached on our test unit. However, it should be noted that this particular sample had already passed through several hands for reviews and may have been subjected to above-average use, which could have influenced its brightness.

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
18.8 ms ... rise ↗ and fall ↘ combined↗ 17.8 ms rise
↘ 1 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (20.4 ms).
       Response Time 50% Grey to 80% Grey
2.4 ms ... rise ↗ and fall ↘ combined↗ 1.4 ms rise
↘ 1 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 9 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32 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 250 Hz
Amplitude: 25 %

The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) .

The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8291 (minimum: 5 - maximum: 343500) Hz was measured.

Performance

The Lenovo Chromebook Plus Gen 10 marks a significant shift in the ChromeOS landscape, primarily due to its processor. It is the first device to feature the new MediaTek Kompanio Ultra 910, a high-end System-on-a-Chip (SoC) designed specifically for Chromebooks.

This is noteworthy because it introduces an ARM-based processor to the "Chromebook Plus" lineup, a category of high-performance devices that has until now been exclusively powered by chips from Intel and AMD. With this release, the Lenovo device establishes itself as a new performance reference.

SoC and System Performance

The performance of the MediaTek chip is impressive. In various benchmarks, the Kompanio Ultra 910 clearly pulls ahead of its competitors, delivering a level of performance unmatched by any recently reviewed Chromebook. This translates to a very smooth user experience, whether handling everyday tasks like browsing with numerous open tabs or running productivity applications.

The Kompanio Ultra 910 also manages more demanding 3D calculations without difficulty. This is handled by the integrated Immortalis-G925 MC11 graphics unit, which is competitive with Intel's Iris Xe graphics chips. Taking a look at the benchmark results shows that the new Chrome 14M9610 from Lenovo is truly one of the best Chromebook Plus alternatives.

Emissionen & Energie

Noise Emissions

The MediaTek Kompanio Ultra 910 does not require active cooling. As a result, the Chromebook is completely silent during operation.

Temperature

The trade-off for the completely silent, fanless cooling becomes apparent in the surface temperatures under heavy load. During our stress test, we measured localized peaks of up to 41°C (106°F) on the top surface around the keyboard, and as high as 45°C (113°F) on the bottom of the device.

However, during everyday activities like browsing the web, watching videos, or using office apps, the temperatures remain comfortably low and are not a cause for concern.

Speakers

Lenovo has equipped this system with a total of four speakers. They are arranged to fire sound both upwards through grilles next to the keyboard and downwards from the chassis. This setup creates a surprisingly spacious and rich sound.

Power Consumption

Lenovo has delivered a very energy-efficient device. This becomes particularly clear when comparing it directly to other devices, such as the Samsung Galaxy Chromebook Plus. Despite the MediaTek Kompanio Ultra's noticeably higher processing power, the Lenovo Chromebook uses far less power when subjected to the same workload.

Here is where the processor's contemporary ARM architecture makes the most of its efficiency advantage over Intel chips, which are present in many rival models.

Battery Life

Lenovo officially claims a runtime of up to 17 hours for the Chromebook Plus 14 (14M9610). In our own Wi-Fi web surfing test, conducted at an adjusted display brightness, the device lasted for an impressive 15+ hours. This result is even more remarkable considering our review unit had been used previously, suggesting its battery may have already experienced some wear.

This results put the Lenovo Chromebook ahead of all the other "Chromebook Plus" models we've tested so far, demonstrating its remarkable endurance for extended periods of time without an external power source.
