Although the Kaby Lake-powered machines are the latest craze, the Skylake generation of CPUs is still around and budget laptops sporting the 6th Generation are often the most sensible solution for the general user. That’s why we are doing a review of the ultra-budget Dell Vostro 15 3559, which should satisfy the needs of a the not-so-picky businessmen.

Its target audience is the same as the HP ProBook 450 G3 but still sells for somewhat lower price, which has also reflected on the features. The ProBook 450 G3 is probably the better choice all-around but don’t dismiss the Vostro 3559 yet. For its asking price, the notebook offers strict and simplistic design, discrete GPU if your line of work requires some extra graphics power and a decent battery performance. And what about the rest concerning business consumers? Let’s find out…

Retail package

The notebook comes in a standard box containing the usual user manuals, AC cord and charging brick.

Design and construction

The chassis of the Vostro 3559 is identical to the Inspiron 3552. It’s so identical that even its dimensions and weight almost match with just 3 mm difference in height and a little bit over 200 gr in weight. Of course, the Vostro 3559 is the bulkier one since it uses a standard fan to keep the Core i5-6200U cool while the Inspiron 3552 we tested earlier this year had a passive-cooled Pentium N3700 processor.

Anyway, most of what we didn’t and did like about the Inspiron 3552‘s design and build stands true for the Vostro 3559 as well. We’ve got again the bouncy lid with textured plastic finish that attracts fingerprints and tight hinges, which don’t allow one-handed opening of the laptop. The bottom piece once again gives access to some of the hardware like HDD and RAM via a service cover.

The sides follow the usual design signature for Dell’s lower-end lineup with a glossy finish and flat shape. Though, the port distribution is quite different from the one on the Inspiron 3552. The left side adopts the LAN, VGA, USB 3.0 and an SD card reader. Whereas the right side goes along with two USB 2.0 connectors, 3.5 mm audio jack and the optical drive. The profile measures at 24 mm so portability is definitely a feature here.

Continuing with the interior, we find the same textured somehow soft-touch plastic finish around the keyboard and touchpad. The material ensures rigid base with no apparent flexibility in the keyboard section and palm rest area but still attracts too many fingerprints and smudges. Speaking of the input devices, the keyboard feels a bit mushy with less than optimal key travel and no feedback to compensate for that. You might think that we are overreacting for a laptop at this price range but since it’s business-oriented, we expect nothing less than comfortable typing experience. On the contrary, the touchpad feels pretty nice without wobbles and offers light mouse clicks and responsiveness. The surface isn’t exactly the best for gliding your finger across it but it’s a small setback to consider.

Again, there’s nothing special about the notebook’s design and the only thing that we genuinely liked is the rigid base and comfortable touchpad. The rest is just okay and we would like the future model with more appropriate keyboard for the target audience.

Disassembly, maintenance and upgrade options

Since the Inspiron 3552 and Vostro 3559 share the same casing, the disassembly process is identical. You will have to remove all the screws around the bottom but keep in mind that there are some under the optical drive, service lid and the battery. Then, proceed by popping out the keyboard as there are several screws beneath it as well.

The only difference is that the Vostro 3550’s motherboard is flipped face up and the cooling design is slightly different.

Storage upgrade options – 2.5-inch HDD

As reperesentative of the low-end segment of the market, the Vostro 3559 features only one 2.5-inch slot for HDD or SSD. Our unit came with 1TB Seagate HDD>

Other components

The Wi-Fi card is easily accessed by removing the service lid.

But as far as the battery is concerned, you won’t need any tools to access it. It’s held by a lever switch and it’s rated at 40Wh.

Cooling system

The cooling design is fairly simple – just a big cooling fan pushing the hot air out of the chassis through a big vent opening on the side. The fan is connected to the CPU’s heat sink via a copper heat pipe.

Display quality

The notebook uses a TN WXGA panel with HD (1366×768) resolution manufactured by LG Philips with model number LP156WHU-TPA1. This means that the pixel density is just 100 ppi and the pixel pitch is 0.253 x 0.253 mm. It can be considered as “Retina” when viewed from a distance equal or greater than 86 cm.

There’s a noticeable color shift under a 45-degree angle as you can see in the image below.

We measured a maximum brightness of just 183 cd/m2 in the middle of the screen and 190 cd/m2 as average so the maximum deviation is just 12%. It will be sufficient for indoor use but if there’s a strong light source or if you are outside working, you will find it uncomfortable. The matte finish will reduce the glare, though. And as far as color temperature is concerned, it’s deviating from the optimal 6500K. We measured 7590K so colors will appear colder than usual. The contrast ratio is extremely low measuring just 280:1 before calibration and 240:1 after.

The maximum color deviation dE2000 is 2.4 in the left part of the screen. Values above 4.0 are unwanted.

Color reproduction

To make sure we are on the same page, we would like to give you a little introduction of the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.

Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.

Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.

The sRGB coverage of the screen is 56% and it’s presented with a yellow dotted triangle in the graph below.

Below you will see practically the same image but with the color circles representing the reference colors and the white circles being the result. You can see main and additional colors with 25%, 50%, 75% and 100% saturation inside the sRGB gamut before and after calibration.

We created the “Office work/Web design” profile with a target color temperature of 6500K (D65), optimal gamma under sRGB mode and 140 cd/m2 luminance.

We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc. You can check out the results at factory condition and also, with the Office & Web Design profile.

The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.

The left side of the image represents the display with stock settings, while the right one is with the Gaming & Movie Nights profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle and the surrounding light conditions.

Response time

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and reverse.

We recorded Fall Time + Rise Time = 18 ms.

PWM (Screen flickering)

Pulse Width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.

Our equipment was able to detect pulsations from 0 to 99% screen brightness but at higher than usual frequencies making it relatively safe for working long hours. However, some users with extra sensitive eyes might feel the 20.3 kHz flickering.

Blue light emissions

Installing of our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our specialized article on Blue Light.

You can see the levels of emitted blue light on the spectral power distribution (SDP) graph.


We were expecting mediocre performance from the panel, considering the price range of the product, and most of the drawbacks like excessive blue light emissions, PWM, color inaccuracy, gamma and color temperature can be fixed by installing our profiles. However, the low maximum brightness and extremely low contrast ratio can’t be fixed with just a software tweak and you might have to settle in this regard.

We used a freshly-installed Windows 10 (64-bit) when testing the unit and if you also wish to perform a clean install of the OS, we suggest downloading the latest drivers from Dell’s official support page.


The Vostro 3559 relies on a 40Wh battery unit when it’s off the charger, thus the endurance of the machine of your everyday tasks will be slightly above the average for this price range. The notebook scored a runtime in the web browsing test. Of course, all tests were performed with the usual settings – Wi-Fi running, Windows battery saving feature turned on and screen brightness set to 120 cd/m2.

Web browsing

In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.

Just around the average for this price range – 332 minutes (5 hours and 32 minutes).

Video playback

For every test like this, we use the same video in HD.

Considerably lower but still on par with the competition – 291 minutes (4 hours and 51 minutes).


We recently started using F1 2015’s built-in benchmark on loop in order to simulate real-life gaming.

Of course, the gaming test took a toll on the battery – 111 minutes (2 hours and 51 minutes)
