Lenovo E31-80 (6200U, HD) Laptop Review

Sascha Mölck (translated by Martina Osztovits), 04/21/2017

Mobile companion. Lenovo's 13.3-inch laptop delivers good battery runtimes, a solid-state disk and a quiet system noise. It uses Windows 10 Pro as the operating system. The incorporated display is not convincing.

The Lenovo E31-80 is a 13.3-inch office notebook. We are already familiar with the computer. It is the similarly designed successor of the Lenovo E31-70, which we have already had under review. Changes can be found inside: While the E31-70 series comes with Broadwell processors, the E31-80 series uses Skylake processors. The competition includes devices such as the Asus X302UV, the Acer Aspire ES1-332, the Medion Akoya S3409, and the HP ProBook 430 G4.

Since the E31-70 and the E31-80 use the same design, we will not cover case, connectivity, input devices, and speakers in detail here. Information about these are available in our Lenovo E31-70 review.

The matte 13.3-inch display features a native resolution of 1366x768 pixels. Brightness (222.4 cd/m²) and contrast (433:1) are disappointing. We expect better results. Pro: The display does not show PWM flickering at all.

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 not detected

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5482 (minimum: 43 - maximum: 142900) Hz was measured.

The DeltaE-2000 shift is 12.09 in the state of delivery (target value smaller than 3). In addition, the display has a distinguished bluish cast.

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
26 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 6 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.8 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 25 ms rise
↘ 19 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. » 62 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43 ms).

Lenovo has equipped the E31-80 with a viewing-angle dependent TN panel. Thus, the screen is not legible from every position. You can only use the computer outdoors when the sun is not shining too brightly.

Performance

With the E31-80, Lenovo offers a 13.3-inch office notebook. The incorporated processor delivers enough performance for office and Internet applications. Our test model costs about 600 Euros (~$644). Other configurations are also available. Currently, the cheapest representative of the series is available for about 480 Euros (~$515).

Processor

Intel's Core i5-6200U (Skylake) dual core processor can be found inside. It is a mid-range CPU, which should meet the requirements of most users. The processor is one of the efficient ULV models (TDP: 15 watts). The CPU features a base clock of 2.3 GHz. The Turbo can increase the clock rate to 2.7 GHz (both cores) or 2.8 GHz (only one core). It is used in mains operation and on battery.

We check whether the Turbo is used permanently by running the Multithread test of Cinebench R15 in a loop for about 30 minutes. The results of the E31-80 are consistent without exception. Hence, a performance loss does not occur.

System Performance

A fast solid-state disk and a powerful processor ensure a fast system, which achieves a good result in the PC Mark 8 Home benchmark. Overall, the computer delivers more than enough performance for office and Internet applications. It is not possible to improve the system performance. Lenovo has already maxed out the possibilities.

Storage Device

Lenovo has equipped the E31-80 with a solid-state disk from Samsung. It is a 2.5-inch model with a total capacity of 256 GB. About 170 GB is free on the system drive (C:) in the state of delivery. A further 22 GB (of about 25 GB) is available on the Lenovo Partition (D:). Drivers and the installation files of the pre-installed software are stored on the latter. The rest of the capacity is used by the Windows installation and the recovery partition. The transfer rates of the SSD are good.

Graphics Card

Intel's HD Graphics 520 GPU is responsible for video output. It supports DirectX 12 and works at 300 to 950 MHz. The results of the 3D Mark benchmarks are normal for this GPU. It is not possible to improve the graphics performance by adding a second RAM module (enables dual-channel mode), since the E31-80  features only one RAM slot.

Gaming Performance

The Lenovo computer can smoothly run a few games. This is primarily true for games with moderate hardware requirements. However, even such games require selecting low resolutions and quality settings. Current hits, such as “Mass Effect Andromeda” are not playable, since the performance of the CPU-GPU combination is far too low.

Emissions & Energy

System Noise

In idle mode, the fan of the computer often stands still and the laptop falls silent. Even when the fan works at low speed in this scenario, it is not really audible. The fan does hardly get louder under load. We measure a noise level of 34.2 dB(A) during the stress test.

Temperature

the Lenovo E31-80 during the stress test

The E31-80 behaves the same way in our stress test (Prime95 and FurMark run for at least one hour) on mains operation and on battery. The processor works at 2.3 to 2.4 GHz at the beginning. Later, the clock rate falls slowly. After about one hour the clock rate is 2 GHz. The graphics core works at 900 to 950 MHz. Later the clock rate levels off at 950 MHz. The temperature increase remains within limits. During the stress test, it exceeds 40 °C (~104 °F) in three measurement segments.

Power Consumption

The E31-80 does not show any anomalies in this respect. We measured a maximum power consumption of 7.5 watts in idle mode. During the stress test, it climbs to 26.4 watts. The power consumption would be higher if the CPU used its Turbo. The power adapter is rated at 45 watts.

Battery Life

Our practical Wi-Fi test simulates the load needed to open websites via a script. The "Balanced" profile is enabled, the laptop's energy-savings functions are disabled, and the screen's brightness is set to approximately 150 cd/m². The E31-80 achieves a battery life of 7:02 h. Therewith; it surpasses the Broadwell predecessor by more than 3 hours.

In review: the Lenovo E31-80 80MX0107GE. Test model provided by notebooksbilliger.de

Lenovo uses a Core i5 processor of the Skylake generation in the E31-80. It delivers sufficient performance for office and Internet applications. Compared to the Broadwell processors in the E31-70 series, the Skylake model performs only slightly better. The CPU has a higher impact on the battery runtimes.

The Skylake processor improves the battery runtimes significantly.

The computer works quietly and does not get too warm. A solid-state disk ensures a fast system. It is possible to replace the SSD, but this requires opening the case. The incorporated keyboard appeared good and suitable for frequent typing.

As in many notebooks, the display is the biggest weakness of the E31-80. Lenovo is using a dark, low-contrast model with narrow viewing angles. The display will not win prizes. The warranty period of only one year is  another point of criticism. We expect two years warranty these days. In addition, we are missing a Type-C USB port.
