Schenker Slim 15 L17 (Clevo N751WU, i7-8550U, FHD) Laptop Review

Schenker’s Slim 15 L17 is a pure and straight office/business notebook offering plenty of performance. The base model starts at around 730 Euros (~$907) and features Intel’s Core i5-8250U and 8 GB of RAM but lacks fast SSD storage. Instead, it is equipped with a standard 500 GB hard drive. As is quite common for Schenker, the notebook is highly configurable and can be adjusted to one’s liking. Given that this particular model lacks a dedicated GPU neither the graphics card nor display are configurable. Interchangeable hardware includes the processor, the RAM, the mass storage device, the Wi-Fi card, and an optional UMTS/LTE modem. All this obviously adds up, and accordingly our review unit cost 1,350 Euros (~$1678) and was slightly more expensive that the manufacturers’ suggested configuration. For the sake of better comparability, we have picked the following devices at a similar price point as our review unit:

Case & Connectivity
Just like its smaller brother, the Slim 14, the Schenker Slim 15 is made almost entirely out of plastic. Display lid and top case are gray and smooth, bezels and bottom cover on the other hand are black and slightly roughened. Unfortunately, the surfaces look much more premium than they feel. They are not at all pressure resistant and flex almost immediately. The display lid can be easily warped but successfully resisted pressure applied to the back of the display, which showed no visible ripple effect whatsoever. The removable and therefore user-replaceable battery is rare these days. Unfortunately, the case lacks dedicated maintenance openings for easier hardware access and requires removal of the base’s entire bottom cover. On the plus side, this turned out to be fairly straightforward and once disassembled, one has access to SSD and RAM, among other things.
Connectivity
In addition to the usual variety of ports, the Schenker Slim 15 also features a USB 3.1 Gen 2 port but lacks a smart card reader. Port spacing is somewhat cramped on the right-hand side due to the optical drive.
SD Card Reader and Communication
Average transfer rates were only mediocre at best, but at least the SD card reader is connected via USB 3.0. As always, transfer rates were determined using our 64 GB Toshiba Exceria Pro SDXC UHS-II reference card. Wi-Fi performance was only average as well. An Ethernet port is available for all those users for whom the Intel dual-band Wireless-AC 8265 is too slow.

Warranty and Accessories
Included in the box is a high-quality microfiber duster as well as two CDs containing drivers and other software. The notebook comes with a 24-month limited pickup & return warranty, which can be extended to include a free check-up for an extra 60 Euros (~$75). This means that while still in warranty, you can send in your device to Schenker for a proper cleaning and/or maintenance. 160 Euros (~$199) more gets you a warranty extension up to 36 months including the above-mentioned check-up.

Input Devices
The Slim 15’s keyboard appears to be of high quality, and it worked reliably and well during our tests. The keys sit tight and do not wobble, their actuation and pressure points are well defined, and typing fast on the keyboard was no problem at all. The 15 x 15 mm large slip-proof keys emitted a noticeable clatter when typing, but it was far from annoying. The layout is well thought out, and the five-stage keyboard backlight a more than welcome addition.
The 10.5 x 5.2 cm (~4.1 x 2 in) large touchpad with support for multi-touch gestures worked fairly well, but lacked input precision around the corners and along the bottom edge. The dedicated mouse buttons’ click sounds were pleasantly quiet.
Display
The 15.6-inch matte FHD IPS display is made by LG and completely non-reflective. We determined maximum brightness to be at 336 nits on average, and its brightness distribution of 93% was significantly better than, for example, on the HP EliteBook 755’s display. Thanks to a black level of 0.3 nits the contrast ratio was a very good 1,110:1, and while we did find evidence of PWM flickering the frequency was very high and thus unproblematic by and large. A very positive aspect is the display’s complete lack of clouding. Overall, we would say display quality was very decent. Color accuracy was only slightly off (DeltaE deviation for colors and gray scale: 4.7 and 3.5, respectively) and easily addressed and improved through calibration. As always, the resulting ICC profile can be found for download in the box below.

Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 20660 Hz | ≤ 99 % brightness setting | |
The display backlight flickers at 20660 Hz (worst case, e.g., 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 20660 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8619 (minimum: 5 - maximum: 343500) Hz was measured. |
Color space coverage was about as good as the HP EliteBook 755 and the Fujitsu LifeBook U757: 82.7% sRGB and 54.2% AdobeRGB. Outdoors the display remained easily readable even in bright sunlight but as expected was incapable of competing against direct sunlight. As expected, viewing angles were superb. It is, after all, a typical IPS panel with decent visibility from all angles.
Performance
Positioned as a pure and straight business notebook, the Schenker Slim 15 is made for typical office tasks. Its Intel Core i7-8550U is more than powerful enough, 16 GB of RAM are more than plenty, and 512 GB of fast SSD storage are more than one could ask for in an office notebook. Unfortunately, the more affordable entry-level base model is equipped with a standard hard drive, which we would strongly advise against. Our recommendation is a combination of SSD and HDD.
Processor
The biggest update on the Schenker Slim 15 is its processor: the 7th generation processor has been retired and replaced with an 8th generation Intel Core microprocessor. Our review unit was equipped with the currently fastest CPU available for the Schenker Slim 15, an Intel Core i7-8550U. It features four physical cores, runs at 1.8 - 4.0 GHz, and is much faster than its direct predecessor. Only the Dell Inspiron 15 equipped with the exact same CPU was able to outperform the Slim 15 in our benchmarks.
Further Core i7-8550U benchmarks and details can be found here.
Running our Cinebench R15 multi-thread loop the Core i7-8550U managed to hold its own over long periods of sustained load. In the past, we have seen similarly equipped notebooks incapable of maintaining their initially high level of performance for more than a few minutes, and the Slim 15’s ability to do so hints at a very good and efficient cooling solution. One single dip aside long-term performance was much more consistent and continuous than on the Dell Inspiron 15.

Storage Devices
Our review unit was equipped with a blazingly fast 512 GB SSD made by Samsung (960 PRO). In addition, the Slim 15 offers a secondary 2.5-inch SATA storage bay in addition to the M.2-2280 slot, the only limitation being that it only supports 7 mm storage devices.

Graphics Card
The integrated Intel UHD Graphics 620 is only slightly faster than the previous iteration, the Intel HD Graphics 620. However, the Dell Inspiron 15 was equipped with a dedicated Nvidia GPU and thus playing in a completely different league. Overall, the integrated GPU offers decent performance and hardware support for high definition video decoding.

Gaming Performance
3D games are certainly not one of the Slim 15’s strong points, and accordingly even older games such as BioShock Infinite run rather poorly. Simpler and less demanding games (think browser games) are no problem though, and will run smoothly.

Emissions & Energy
System Noise
When idle, the Schenker Slim 15 is mostly soundless. This obviously changes if you are running a spinning hard disk inside the case. Average load was also not too strenuous for the fan. However, it revved up quickly under maximum load and maxed out at 45.9 dB(A) during our stress test. The included ControlCenter application allows for even further increases, and the absolute maximum measured by us was 52.3 dB(A). That said, automatic fan control worked reliably well and we see no reason to mess with the settings and switch to manual control.

Temperature
The left-hand side became quite warm under load, and the hottest spot on the entire case was found to be at the bottom towards the rear part of the case (41.8 °C/107.24 °F). Compared with its competitors, only the ThinkPad L570 remained significantly cooler.
The CPU heats up to 77 °C (170.6 °F) under load and remains at a solid 1.8 GHz (base frequency). Due to the fact that CPU and GPU have a shared thermal envelope of no more than 15 W, the GPU has to clock down to 300 MHz, though. Fortunately, we found no evidence of thermal throttling in our review unit’s CPU. Immediately after our stress test, 3D performance was at the same level as it was before running the stress test.
(+) The maximum temperature on the upper side is 38.5 °C / 101 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(±) The bottom heats up to a maximum of 41.8 °C / 107 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.1 °C / 77 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 29.2 °C / 84.6 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-1.6 °C / -2.9 F).

Speakers
The two downwards firing speakers are located towards the front of the base. This can be advantageous on a hard and smooth surface like a table, where the sound is reflected off the surface, but quite problematic on a soft surface where the sounds are highly muffled. Bass is practically non-existent and overall sound quality is rather tinny. All things considered, sound quality was underwhelming and substandard, and we strongly suggest using headphones or speakers instead.

Power Consumption
Power consumption when idle was between 7.2 and 12.6 W, and thus on a par with its competitors. We did see short bursts of up to 45.5 W, which is more than the included 40 W charger is capable of delivering. In the end, power consumption settled around 37 W, which means the charger is borderline adequate for maximum load. That said, it should not cause any problems during everyday use, and the battery did not discharge under maximum load.

Battery Life
According to Schenker, the Slim 15 should run up to six hours on battery, but we found this to be true for near idle workloads only. In our real-world Wi-Fi test the Slim 15 ran out of power after just 4:35 hours, a decent battery life considering the more than adequate raw processing power and the bright display. Both front-runners feature much higher-capacity batteries, and let’s not forget that the battery on the Schenker Slim 15 is user-replaceable and can be swapped without requiring any tools.

Verdict
Schenker’s Slim 15 is a highly configurable simple office notebook with a plain design. Unfortunately, it lacks the additional security features users require from business notebooks these days. Mobility is noticeably impaired by the notebook’s poor battery life - the Slim 15 is not going to last a full day on battery.
The Schenker Slim 15 is a quiet yet powerful notebook. If battery life happens to be towards the bottom of your priorities list, this might just be the right notebook for you.
Overall, we liked the Slim 15’s amazing CPU performance and incredibly fast SSD thanks to which using the device turned out to be a very pleasant experience. The display with its matte surface, its high maximum brightness, and its superb viewing angles were also a big plus in our book. The input devices were decent despite the touchpad’s input detection issues around its edges.
