Lenovo E51-80 80QB0008GE Notebook Review

Sascha Mölck, Stefanie Voigt (translated by Liala Stieglitz), 07/16/2016

Office worker. Lenovo's E51-80 is situated below the ThinkPad E series. Accordingly, the prices are low - but the E51-80 cannot really be called cheap. The fast SSD and Core i7 processor boost the price. However, this does not compensate for the at most mediocre keyboard and not very convincing battery life.

With its E51-80, Lenovo offers an office laptop for both private and professional users. The laptop is familiar to us. We tested the largely identical predecessor model a few months ago – the Lenovo E50-80. Rivals of the E51-80 are laptops such as HP's 250 G4HP's 350 G2HP's ProBook 450 G3,Dell's Latitude 3550Lenovo's ThinkPad E560Acer's TravelMate P257-M.

Since the E50-80 and E51-80 feature an identical build, we will not go into details about casing, connectivity, input devices or speakers. The relevant information can be found in the review of the Lenovo E50-80.

Case & Connectivity

The E51-80 has a maintenance hatch that conceals two working memory banks, the hard drive slot, Wi-Fi module and BIOS battery. Only one of the working memory banks is filled. Replacing the hard drive is not a problem. 2.5-inch models with a height of 9.5 and 7 mm (~0.38 and 0.28 in) can be installed. The fan cannot be accessed without opening the casing.

The number and positioning of interfaces on E51-80 are the same as those of its predecessor. One difference is found: The E51-80 comes with a docking port, making it possible to connect Lenovo's OneLink docking solution to the E51-80.

Lenovo's E51-80 is equipped with a matte, 15.6-inch screen that has a resolution of 1366x768 pixels. Both the brightness (207.6 cd/m²) and contrast (478:1) are too low for a laptop in this price range. Positive: The screen does not display PWM flickering.

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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9868 (minimum: 43 - maximum: 142900) Hz was measured.

The screen shows a DeltaE 2000 color deviation of 12.03 in the state of delivery - not a good rate. A rate of less than 3 would be desirable. Furthermore, the screen suffers under a visible bluish tint.

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
25 ms ... rise ↗ and fall ↘ combined↗ 8 ms rise
↘ 17 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. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.5 ms).
       Response Time 50% Grey to 80% Grey
47 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 24 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. » 75 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40.8 ms).

Lenovo has installed a viewing angle dependent TN panel in the laptop. Thus, the screen is not legible from every position. The E51-80 cannot really be used in the outdoors due to the screen's far too low brightness. This is at most possible in cloudy conditions or in shaded environments.

Performance

Lenovo's E51-80 is a 15.6-inch office laptop, aimed at private and professional users. Skylake processors are installed in this series. Thus, it has enough computing power for all common application fields. Our review sample costs roughly 700 Euros (~$773). Other configurations also exist. Currently the cheapest model costs around 490 Euros (~$541).

Processor

Our test device is the most powerful model of the E51-80 series. A frugal ULV processor (TDP: 15 watts) in the shape of Intel's Core i7-6500U (Skylake) model is inside. The processor clocks at a base speed of 2.5 GHz, which can be boosted to 3 GHz (both cores) or 3.1 GHz (one core) via Turbo. Turbo is almost always completely utilized. The processor clocks at "only" 2.8 to 2.9 GHz when calculating Multithread applications in battery mode.

System Performance

A fast solid-state drive and a strong processor ensure a fast system. We did not encounter any problems. The PCMark benchmark scores are very good. A look at our comparison chart shows that a Lenovo ThinkPad E560 based on a stronger AMD graphics core sometimes scores worse than the E51-80. This is due to the different desktop resolutions. The ThinkPad is equipped with a Full HD screen while the E51-80 has an HD panel. The ThinkPad would score better than the E51 when its desktop resolution is reduced to HD. It is possible to increase the E51-80's system performance by, for example, installing a second working memory module.

Gaming Performance

The combination of Radeon's graphics unit and the Core i7 processor allows rendering many games smoothly. However, the user will have to be satisfied with low resolutions and low to sometimes medium quality settings in most cases. This applies to games that do not have very high hardware requirements. Performance-driven sensations such as "Hitman" will never achieve sufficiently high frame rates.

Emissions & Energy Management

System Noise

Since the E51-80 is an office device, excessive noise development should not distract its owner at work - and it does not. The fan is usually inactive in idle mode and silence prevails. The noise level climbs to only 33.8 DB(A) during the stress test - a very good rate.

The E51-80 performed our stress test (Prime95 and FurMark run for at least one hour) differently in AC and battery mode. The processor clocked at 2.7 to 2.8 GHz in battery mode, while the graphics unit clocked consistently at 400 MHz. The GPU achieved its full speed (955 MHz) when the stress test was performed in AC mode. The CPU's clock speed constantly fluctuated from 800 MHz to 1.7 GHz. The laptop heated up moderately. Forty degrees Celsius (~104 degrees Fahrenheit) was exceeded on some measuring points.

Power Consumption

We measured a maximum idle power consumption of 8 watts - a good rate. The rate increased to 44.6 watts reducing only briefly in the stress test. The power consumption fluctuates since the CPU performs the stress test at varying speeds. The requirement will range around 33 watts (+/- 5 watts) in gaming routine. The power supply has a nominal output of 65 watts.

Battery Runtime

Our practical Wi-Fi test simulates the load required for opening websites. The "Balanced" profile is enabled, and the screen's brightness is set to approximately 150 cd/m². The E51-80 achieves a runtime of 4:39 hours - not an outstanding rate. We expect at least 5.5 to 6 hours from a modern ULV laptop.

Lenovo's E51-80 is a 15.6-inch office laptop. Its price is slightly lower than that of the ThinkPad E series, and is aimed at professional and private users. It does not lack computing power thanks to the Core i7 processor. Games can at least be played conditionally. The laptop runs quietly over the entire load range and only heats up moderately. Replacing the SSD is not a problem since the E51-80 has a maintenance hatch. The installed keyboard will satisfy the needs for home use. Prolific writers should, however, opt for a ThinkPad model. The battery life can also be called average at most. We expect more in this regard nowadays. The screen will not excite anyone, either: It is dark with low-contrast and viewing angle unstable.

The main problem of the E51-80: Price and performance are not in line. The price would have to be reduced by 150 Euros (~$165).

The question Lenovo should ask itself is why should anyone spend 700 Euros (~$773) on the E51-80 when a ThinkPad E560 (model: 20EV002UGE) is available for 720 Euros (~$795). Although the latter is equipped with a somewhat weaker processor and a conventional hard drive, it can score with a stronger graphics unit (Radeon R7 M370), Full HD panel and much better keyboard. The price difference of the cheaper models of both series is also quite narrow. E51-80 models start at 490 Euros (~$541), while ThinkPad E560 models start at 520 Euros (~$574). In any case, the ThinkPad always offers the better keyboard - an important aspect in an office device.
