Maintenance

Two panels on the bottom cover the SSD, WAN module, SIM slot, WLAN module, and two SODIMM slots. The optical drive can be removed and replaced with additional drives if desired.

Warranty

Three-year warranty comes standard as opposed to only one or two years on most other laptops.

Input Devices

Keyboard

The removable keyboard is excellent and easy to type on. Keys have adequate travel with crisper feedback than most Ultrabooks. Clatter, however, is loud when typing.

Dedicated auxiliary keys for volume or brightness would have been useful especially for this particular category.

Touchpad

The touchpad (10 x 5 cm) is not Precision enabled. Two-finger inputs like scrolling and zooming are still supported, but they are slow and unreliable. Furthermore, the cursor moves at a lower frame rate when compared to using an external mouse. We recommend using an external mouse whenever possible for more accurate and reliable clicks.

Display

The Chi Mei N156HGE-EA2 panel on our test unit can also be found on the Acer Aspire E5-551G and Lenovo ThinkPad T550. The problem is that these laptops are from 2014 which means the DuraBook is using a six-year old TN panel. Colors are way off and contrast is low for a poor visual experience out of the box. We understand that the system is not designed for editing or watching movies, but it's still far behind the curve in its own category as most other rugged laptops now come with higher quality IPS panels instead.

Brightness is average as we're able to record a maximum of only 284 nits. Pulse-width modulation is present on all brightness levels up to 99 percent which might impact users who are sensitive to onscreen flickering.

Further measurements with an X-Rite colorimeter reveal an overly cool color temperature with inaccurate colors as a result. Once we calibrated the display, however, colors and grayscale would improve dramatically. We recommend calibrating the display if possible because the visual experience will improve noticeably.

Display Response Times

ℹ
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
19.6 ms ... rise ↗ and fall ↘ combined↗ 14.4 ms rise
↘ 5.2 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. » 34 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (22.3 ms).
   ↔    Response Time 50% Grey to 80% Grey
24.4 ms ... rise ↗ and fall ↘ combined↗ 12.8 ms rise
↘ 11.6 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 0.25 (minimum) to 636 (maximum) ms. » 26 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (35.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 301.2 Hz ≤ 99 % brightness setting

The display backlight flickers at 301.2 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 301.2 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19046 (minimum: 5 - maximum: 3846000) Hz was measured.

Outdoor visibility is poor due to both the limited brightness and limited viewing angles of the TN panel. The matte display helps to reduce glare, but it can only do so much on its own.

GPU Performance

The integrated UHD Graphics 620 holds no surprises. The years-old GPU is unfit for any graphics-heavy workloads as one would expect. This particular model does not offer any discrete graphics options either unlike the Dell Latitude 7424 and its more capable Radeon RX 540 GPU.

See our dedicated page on the UHD Graphics 620 for more technical information and benchmarks.

Emissions

System Noise

The fan will idle during low loads like word processing. If browsing or video streaming, fan noise will jump from a silent 29.3 dB(A) to 31.7 dB(A). If running higher loads like gaming, fan noise will increase to 35.5 dB(A) to be audible but not bothersome. The fan tends to pulse when running medium loads instead of remaining constant.

Running extreme loads like Prime95 will induce a fan noise of up to 38 dB(A) temporarily before it drops back down to a constant 35.5 dB(A).

We can notice no major electronic noise or coil whine on our unit.

Temperature

Surface temperatures are not an issue no matter the load due to the ULV CPU and thick build. At worst, hot spots toward the rear of the system can become as warm as 42 C after running Prime95 and FurMark for an hour as shown by the temperature maps below.

Stress Test

We stress the system with synthetic loads to identify for any potential throttling or stability issues. When running Prime95, the CPU would spike up to 3.2 GHz for a few seconds until hitting a core temperature of 82 C. Thereafter, clock rates would drop to a constant 2.5 GHz and 72 C for a few minutes. Eventually, however, clock rates will drop even further to 1.6 GHz with short-lived spikes to 3.3 GHz as shown by our screenshot below. The sudden spikes in clock rate correlate with the short spikes in power consumption that we recorded in the next section below.

Running both Prime95 and FurMark will throttle the CPU down to 1.3 GHz and a core temperature of 81 C.

Performance will drop if running on battery power even when set to the High Performance profile. A 3DMark 11 test on batteries returns Physics and Graphics scores of 1616 and 1557 points, respectively, compared to 6358 and 1754 points when on mains.

Speakers

Audio is sufficient as the limited bass shouldn't be an issue for the target audience. However, we're able to notice slight crackling noises from the speakers when setting the volume to maximum.

Energy Management

Power Consumption

Idling on desktop consumes between 3 W and 9 W while higher loads like 3DMark 06 will consume about 40 W. We're able to record a maximum of 59.8 W from the small (~10.5 x 4.5 x 3 cm) 65 W AC adapter when stressing the processor to 100 percent utilization.

Verdict

In review: Durabook S15AB. Test unit provided by Durabook
In review: Durabook S15AB. Test unit provided by Durabook

Our favorite aspect of the Durabook S15AB is the crisp feedback of the keyboard keys when typing and easy access to ports and internal upgrades. The protective flaps covering the ports on the Panasonic Toughbook FZ-55 and Getac S410, for example, are comparatively more difficult to open and finicky to access.

The one aspect that could use the most improvement would be the TN display and the fickle touchpad control. This is an an old display panel that doesn't hold up very well by today's IPS standards and it isn't bright enough to be used outdoors without needing to squint. The presence of pulse-width modulation could impact nighttime usage as well where lower brightness settings are desirable.

Users can customize and get a quote on the Durabook S15AB through the product page here.
