Acer Extensa 2540 (i5-7200U, FHD) Laptop Review

Sascha Mölck, 👁 Sebastian Jentsch, Tanja Hinum (translated by Stanislav Kokhanyuk), 12/16/2017

Durable. Acer’s 15.6-incher scores some major points with its hardware combination of a Kaby Lake CPU, an SSD and 8 GB of RAM (running in dual-channel mode). The great battery life adds more value to the package. The screen proves to be disappointing, though.

With the Extensa 2540, Acer delivers a simple, yet very well-equipped 15.6-inch office notebook. Our review model is geared towards users who need or desire to have a device with Windows 10 Pro. The laptop is powered by a Kaby Lake processor. Comparable devices include: the HP 15-ba077ng, the HP 15-ay116ng, the Lenovo V110-15IKB and the Asus ASUSPRO P541UA-GQ1532.

Case

The term “functional” best describes the case of the Extensa. Here, Acer forgoes such high-value materials as aluminum and magnesium, and instead it opts for matte, black plastic. The upper side of the chassis is adorned with a grid texture. The back side of the display lid is enhanced with a wave pattern. As a result, the device is not really susceptible to fingerprints and is very easy to grab and hold, when the display lid is closed. The battery is built in. There is a small maintenance hatch on the underside of the device.

All in all, the device has a good build quality. There are no chinks or gaps to speak of. Applying pressure to the usual places (like both sides of the keyboard, below the touchpad) results in some minor bending. However, in our opinion, the chassis could have been more rigid. The same applies to the display lid. It can be twisted with little effort, and when it is twisted, it usually leads to image distortions, which also show up when pressure is applied to the back side of the display lid. The hinges have no trouble holding the display in a set position. The maximum opening angle is 135 degrees.

The Extensa weighs a little bit more than the competing devices. In terms of size, there are no considerable differences.

Connectivity

Acer does not oversupply the Extensa with ports. Three USB Type-A ports (2x USB 2.0, 1x USB 3.1 Gen 1) are available. A USB Type-C port was not included. A monitor can be connected via HDMI.

Acer has put most of the ports on the back side of the device. This shall please those who will use the laptop for stationary work. This way, cables can be put behind the device. However, for this kind of work, a second USB 3.1 Gen 1 port on either the right side or the left side of the device would have been very helpful. Those who need to transfer large chunks of data via external storage devices will have to plug in their storage devices at the back of the device, which soon becomes annoying.

SD Card Reader

The SD card reader belongs to the slow specimens of its kind. When copying large chunks of data, a maximum transfer speed of 27.5 MB/s was achieved. The transfer of 250 JPG image files was completed with a transfer speed of 26 MB/s. Most of the competitors offer SD card readers with similar speeds. Only the Asus ASUSPRO P541UA-GQ1532 and, to a lesser degree, the Acer Aspire 3 A315-21-651Y, stick out from the crowd. We test the SD card reader by means of a reference SD card (Toshiba Exceria Pro SDXC 64 GB UHS-II).

Communication

A Wi-Fi module from Intel.

The Extensa comes equipped with a Wi-Fi module from Intel (Dual Band Wireless-AC 3168). Besides the Wi-Fi standards 802.11a/b/g/n, it also supports the fast Wireless-AC standard. The data transfer speeds that we measured under optimal conditions (no other Wi-Fi-enabled devices in close proximity, a short distance between the notebook and the server PC) are quite average. Most of the competitors offer similar Wi-Fi performance. A Gigabit Ethernet controller from Realtek’s RTL8168/8111 family is responsible for wired connections. It always does what it is supposed to do without any problems.

Webcam

The webcam does not produce a pristine image. Acer has equipped the laptop with a simple VGA camera, which produces pale, washed-out images with a maximum resolution of 640x480.

Security

Besides a Trusted Platform Module (2.0), there are no other security features to talk about. 

Accessories

The Extensa comes with the usual documents (quick-start guide, warranty information). There are no other accessories in the box.

Maintenance

There is a maintenance cover on the underside of the device, through which the SSD and RAM can be accessed. In order to reach such components as the battery and the fan, the case will have to be opened up. For this, the maintenance cover and optical disc drive will have to be removed first. Subsequently, the SSD will have to be removed, as well, to avoid damaging it. Now all the screws on the underside of the device should be undone. After that, the notebook should be placed back on its feet. Now the upper side of the chassis can be removed with the help of a spatula or a (plastic) putty knife. But be careful: Because the upper side is connected to the underside by means of plastic clamps, when you try to remove the topside these clamps can easily be broken. Attention: The upper side is connected to the rest of the chassis via two ribbon cables. Now you can have access to the battery, the fan and the Wi-Fi module.

Warranty

Acer provides the Extensa with a two-year warranty. The warranty’s duration and extent can be customized further. For instance, three years of on-site service can be had for 100 Euros (~$118).

Please see our Guarantees, Return Policies and Warranties FAQ for country-specific information.

Input Devices

Keyboard

The Extensa comes with an unlit chiclet-style keyboard complete with a numeric pad. While the main keys feature a concave depression, the function keys and the numeric pad keys do not. All the keys have a slightly rough surface. They have a short travel distance and a clear actuation point. During typing, the center of the keyboard exhibits some slight flex. However, this does not prove to be annoying. All in all, Acer delivers an “okay” keyboard that is suited for regular typing. Because the Extensa is, primarily, a business device and our review model is specifically geared toward professional users, a keyboard backlight is especially missed here.

Touchpad

The multitouch-enabled ClickPad occupies an area of some 10.5 x 7.8 centimeters (4.1 x 3 in). Therefore, there is enough space for the use of gesture controls. The various gestures can be individually enabled or disabled in the configurations menu of the ClickPad. The smooth surface of the pad makes finger-gliding easy. The corners of the ClickPad register inputs, as well. The pad has a short travel distance and a clear actuation point.

Display

The matte 15.6-inch display of the Extensa has a native resolution of 1920x1080. Both the contrast ratio (316:1) and the brightness (217.2 cd/m²) are way too low. Here we would expect to see values of at least 1000:1 and 300 cd/m², respectively.

Unfortunately, at 90% brightness and below, the screen exhibits PWM-flickering with a frequency of 27,000 Hz. However, such a high frequency should not lead to headaches and/or eye-strain amongst susceptible individuals.

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 27000 Hz ≤ 90 % brightness setting

The display backlight flickers at 27000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 27000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9367 (minimum: 43 - maximum: 142900) Hz was measured.

Extensa vs. sRGB

Extensa vs. AdobeRGB

The display does not shine in terms of color-space coverage, either. Straight out of the box, we measured a DeltaE 2000 color deviation of 9.14 (DeltaE less than 3 is the optimal value here). Moreover, the display suffers from a noticeable blue cast. The display cannot cover either the AdobeRGB color space or the sRGB color space. It can cover merely 56% of sRGB and 36% of AdobeRGB.

By means of our color profile, the color reproduction can be improved. However before downloading it, you should make sure that your laptop has the same display model (manufacturer + model number) as our review device, because otherwise our color profile can result in worse color reproduction. Displays from different manufacturers can often be found within notebooks from the same model range.

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
22 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 4 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 0.8 (minimum) to 240 (maximum) ms. » 26 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise

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. » 50 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.8 ms).

Acer has equipped the laptop with a TN panel with poor viewing angles. Consequently, the display is not legible from every position. Outdoors, the notebook can only be used in the shade.

Processor

The Extensa comes equipped with a dual-core Intel Core i5-7200U (Kaby Lake) processor. What we are dealing with here is a mid-range ultra-low-voltage CPU that should be able to meet the demands of most users. The processor has a base clock of 2.5 GHz and a boost clock of 3.1 GHz (both cores). Intel’s Turbo Boost Technology functions well both when the device is plugged in and when it is running on battery power (this technology allows the CPU’s clock rate to be “boosted” from 2.5 GHz to 3.1 GHz).

Single-core
Single-core
Multi-core
Multi-core

We check if the Turbo boost can be used over a prolonged period of time by running the Cinebench Multi-Core benchmark in a continuous loop for 30 minutes. The results of the Extensa stay consistently on the same level. There are no drops in performance to report.

Cinebench R15 CPU Multi 64 Bit

The results of the benchmarks that we carried out for this review are consistent with those of other 7200U-based notebooks. Compared to its direct predecessor (Core i5-6200U), the Kaby Lake CPU performs better. This can be attributed to higher clock speeds. In terms of technology, there are almost no differences between Skylake and Kaby Lake.

If the performance of the built-in CPU proves to be insufficient, there are alternative solutions based on Intel’s brand-new quad-core ULV CPUs (Core i5-8250U, Core i7-8550U). Although, we would only recommend getting such a CPU if you are going to use applications that can fully utilize the two additional cores. This applies to the applications that are optimized for multi-core CPUs. In everyday use, quad-core ultra-low-voltage CPUs do not offer many advantages over their dual-core counterparts. For instance, when it comes to single-core performance, the Core i5-8250U is only about 10% faster than the Core i5-7200U.

System Performance

Thanks to a combination of an Intel Core i5 CPU, an SSD and dual-channel RAM, the laptop offers more than enough computing power for such usage scenarios as office work and Internet browsing. The results in the PCMark benchmarks are in good order. An increase in overall performance is not possible. Acer has already exhausted all the possibilities.

Attention: Driver Problem

The first benchmark run of the PCMark 8 benchmarks delivered inexplicably low results, which deviated significantly from what we expected. The gap was especially wide in the PCMark 8 Creative benchmark (2882 points vs. 4518 points). The CPU, by the look of it, operated at its maximum boost clock. To check if maybe there were some errors during Windows installation, we put a new SSD in the notebook and reinstalled Windows.

We also installed the latest GPU driver from Intel (23.20.16.4849). This same driver was also installed on the original system from Acer. The results did not change. After that, we installed the previous version of the driver (22.20.16.4815), with which we finally got realistic results in PCMark 8. Thus, we determined that the cause of the problem was the driver. We observed differing results only in PCMark 8, and not in PCMark 7 or 10.

The driver also affected our battery test. With the latest Intel driver installed, the Extensa achieves a maximum battery runtime of 9 hours and 13 minutes. With the previous version of the driver installed, the Extensa achieves 18 hours and 53 minutes of battery life. No other tests or benchmarks have been affected by the faulty driver.

Storage Devices

An SSD from Kingston serves as the system drive. What we see here is a 2.5-inch SATA III SSD with a capacity of 256 GB. Right out of the box, only 206 GB is available to the user. The Windows Installation files and the Recovery Partition take up the rest of the storage space. The transfer rates of the SSD are in good order.

The SSD can be replaced without any problems.

Gaming Performance

The Extensa is, above all, a business device, which is why its gaming performance is not front of mind. Nevertheless, the laptop’s hardware can run a few games with passable frame rates. This applies to games that do not have high system requirements. However, you will have to be content with running these games at low resolution and with low graphical settings. The dual-channel-enabled RAM has a positive effect on gaming performance. The frame rates of our review device are higher than those of laptops whose RAM runs in single-channel mode. However, graphically demanding titles like Destiny 2 are still not playable. In order to run such games, you will need a capable dedicated graphics card.

Emissions

System Noise

The fan.
The fan.

As a rule, the fan stands still in idle operation and under light loads, which leads to silent operation. Under medium and full loads, the fan starts to spin up. During our stress test, we measured a sound pressure level of 37.4 dB(A). When in operation, the fan creates a constant rustling sound. As a matter of fact, under load, the fan can operate at lower speeds than it currently does and still be able to adequately cool the device. A look at the temperatures shows that the device does not get hot at all. Here, Acer can make some adjustments via BIOS updates.

Energy Management

Energy Consumption

When idle, the Extensa draws very little power. Here the power draw peaked at 7.4 watts. During the stress test, in which we run Prime95 and Furmark simultaneously for at least one straight hour, the power draw rose only up to 29 watts, because the CPU was throttled down considerably. When we ran only Prime95, the device consumed 39 watts. The nominal power draw of the AC adapter is 45 watts.

Battery Life

In our practically-oriented Wi-Fi test, the Extensa achieves a runtime of 8 hours and 4 minutes. This test simulates loads that are consistent with surfing the web. The “balanced” profile is selected, the energy-saving functions turned off and the display brightness set to 150 cd/m². The Acer laptop achieves a runtime of 3 hours and 49 minutes in our video test. This test allows us to measure how long a device can play back video with a single battery charge. During this test, we play the short film Big Buck Bunny (H.264, 1920x1080) in a continuous loop. The communications modules are disabled, the energy-saving functions are switched on and the display brightness is reduced to 150 cd/m².

The battery has a capacity of 48 Wh.

Our review device was provided to us courtesy of: Acer Deutschland.

The Acer Extensa 2540-580K features a powerful CPU, a fast SSD and dual-channel-enabled RAM. The device does not get hot under all kinds of loads and operates nearly silently. Therefore, the Extensa offers features and attributes that are associated with most office notebooks. 

With the Extensa 2540, Acer delivers a very durable office device that is going to have to find its audience. The display is going to be a major deal-breaker for many potential buyers.

Fortunately, Acer has equipped the laptop with a small maintenance hatch, behind which the SSD and the RAM are located. Therefore, replacing or upgrading these components should not present any problems. The keyboard, by and large, left an “okay” impression. However, we would really like to have seen a backlight here. With it, Acer could have rounded off the office device, which is what the Extensa is supposed to be. The superb battery life also adds more value to the laptop.

The weakest spot of the device - as often is the case - is the display. Acer uses a dim panel with poor contrast and viewing angles here, which would not have been appropriate even in a 400-Euro notebook (~$470).

With this model, Acer goes, primarily, after professional users, hence the preinstalled copy of Windows 10 Pro. The pro-version increases the price of the device somewhat, which makes the laptop seem rather unappealing to casual users. Acer does not offer an identically-equipped alternative version with Windows 10 Home. The Extensa 2540-56GC comes closest to our review device. However, it only comes with an HD display (1366x768).

Update 13.12.2017: Acer has informed us that the model which we have tested in our review is no longer available, and that it has been replaced by the identically-built model Extensa 2540-54C0.
