Dell Latitude 15 5511 laptop in review: Business laptop for productive work

Thick but light. The Dell Latitude 15 5511 is not exactly what you'd call a small laptop. However, not only is there room for many ports due to the spacious case, but there are also good maintenance options. We will clarify what users can expect from the Latitude 15 5511 in our review.

Dell Latitude 15 5511-VNJNW

After having taken a look at the Dell Latitude 15 5510 with the Intel Core i5-10310U, we now have the Dell Latitude 5511 as a test device. This model is equipped with an Intel Core i5-10400H and 16 GB of RAM. Dell uses a 256 GB SSD for storage in our test configuration, and the Intel UHD Graphics 630 internal graphics unit is responsible for displaying image content.

For a price of approximately 1,200 Euros (~$1,460), the competition in the office sector is quite big, which is why we limit our comparison to the devices listed below. However, other laptops from our database can be added under each section.

Case - Large 15-inch laptop from Dell

The Dell Latitude 15 5511 is made of robust plastic and has a high-quality build. Uneven gaps or the like are not present in our test device. However, the screen can only be opened with two hands, since the base unit doesn't provide enough counterweight. The hinges hold the display firmly in the respective position and allow an aperture angle of up to 180 degrees.

In terms of dimensions, the Dell Latitude 15 5511 is considerably thicker than the comparable competition. The footprint and weight, on the other hand, are similar.

Connectivity - Smart card reader and good maintenance options

Dell equips the Latitude 15 5511 with many ports. However, since the included charger has a USB Type-C plug, this port isn't available when charging if you don't have a corresponding docking station. There is a nano SIM card slot below the microSD card reader for the use of an optional WWAN module.

Communication

The Latitude 5511 can establish wireless connections via Wi-Fi 6 and Bluetooth 5.0 in our test configuration. With our Netgear Nighthawk AX12 reference router, Dell's laptop achieves 1,436 Mb/s for receiving data and 1,361 Mb/s for sending data. Once again, this places the result on par with the Dell Latitude 5510 and also above the rest of the test field.

Webcam

As most current laptops, the Latitude 15 5511 uses a very low-resolution webcam with 0.9 MP. It reproduces colors much too brightly even in good lighting conditions, and it only captures subjects in a blurry way.

Security

Dell equips the Latitude 5511's webcam with a shutter that can be shifted in front of the lens when needed. In addition, there's a fingerprint scanner integrated into the power button that worked reliably in our test. Users can also access a smart card reader. A TPM 2.0 module is present as well.

Accessories

Besides the Latitude 15 5511, Dell only ships a corresponding power adapter with a USB Type-C connector. However, additional accessories can be purchased via the manufacturer's website.

Maintenance

The underside of the Dell Latitude 15 5511 is easy to open after removing all visible screws. Afterwards, the storage drive, RAM, battery, and WLAN module can be accessed. Everything is prepared for the use of a WWAN module, including the antennas.

In our test configuration, 16 GB of RAM was also installed as a single module, so that the second slot is free for an expansion. In addition, there's enough room for a 2.5-inch drive. A SATA port on the motherboard is also free for this, but a connection cable wasn't included with our test device.

Warranty

Dell offers buyers of the Latitude 15 5511 a warranty period of 12 months that can be extended for a fee, though.

Input devices - Laptop with pointing stick

Keyboard

The Dell Latitude 15 5511's keyboard is quiet and well-suited for typing longer text. The pressure point is clearly felt, and only the slightly too small arrow keys need getting used to. The two-stage, glare-free backlight makes the labeling easy to read even in poor lighting conditions. The input field is also protected against splashing water.

Touchpad

Users of the Dell Latitude 15 5511 can use the touchpad with separate mouse buttons or the pointing stick as a mouse replacement. Both methods are well suited for controlling the mouse pointer, and the corresponding buttons provide clear feedback.

Display - Moderate brightness and PWM

Subpixel grid
Subpixel grid

The Latitude 5511's screen consists of a 15.6-inch IPS panel and offers a resolution of 1920x1080 pixels. The brightness is in the middle of our test field at an average value of 241 cd/m2. The illumination of 79% is rather below average.

PWM is used for brightness control, which causes the display to flicker at a frequency of 1,000 Hz when the brightness level falls below 90%. This can lead to difficulties for users with sensitive eyes when working on this display.

With a contrast ratio of 788:1 and a black level of 0.34 cd/m², the Latitude 5511 can't hold its own against the competition in our test field. Colors don't appear very well separated from each other as a result, and black image content is covered with a slight gray veil.

The CalMAN analysis shows that the display already shows colors with an extremely low deviation out of the box. Therefore, calibration only brings a slight improvement.

The Dell Latitude 15 5511 can be used well outdoors as long as places in the shade are preferred. The matte display is not susceptible to reflections, but the brightness is not sufficient to display image content legibly in direct sunlight.

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
30 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24 ms).
       Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 24 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 0.8 (minimum) to 636 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.1 ms).

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 1000 Hz ≤ 90 % brightness setting

The display backlight flickers at 1000 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 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14825 (minimum: 5 - maximum: 2500000) Hz was measured.

The IPS panel of the Latitude 5511 is very viewing-angle stable. Image content can be viewed from almost any angle without it becoming distorted or being displayed with the wrong colors.

Graphics card

The UHD Graphics 630 internal graphics unit from Intel is responsible for displaying image content in the Latitude 15 5511. Its performance is sufficient for applications with low requirements for graphics performance, but it's not suitable for complex 3D applications. Since the GPU benefits from RAM in a dual-channel configuration, users of the Dell laptop can still improve performance a bit with the use of a second RAM module.

In our GPU Benchmarks article, we have listed the performance that can be expected from other graphics cards.

Gaming performance

The Intel UHD Graphics 630 is hardly suitable for games. Only very old titles or those with very low demands on graphics performance can be played smoothly. However, you still have to make do with reduced detail settings and low resolutions to achieve a smooth frame rate.

We have listed the frame rates that can be expected in different titles in our GPU Games article.

Temperature

Stress test
Stress test

According to our measurement, the surfaces of the Dell Latitude 15 5511 heat up to 44.4 °C (~112 °F) under load. However, the laptop only feels a bit warm here, and it can always be used on the lap, for example. The temperatures of the palm rests also remain moderate at all times.

During our approximately one-hour stress test, the temperatures inside the Dell laptop climb to up to 99 °C (~210 °F). The fast-acting fans reduce this value to about 85 °C (~185 °F), which can be maintained until the end of the test. The clock rates are just under 2.6 GHz over the entire period, meaning that the base clock speed is just about maintained. Since a load like in our stress test scenario shouldn't occur in everyday use, users don't have to expect restrictions due to high temperatures.

Business users can work all day with the Dell Latitude 15 5511 without having to carry a power adapter. The battery life is excellent as long as no overly demanding work aside from office programs is required. The input devices and maintenance options leave little to be desired as well.

The Dell Latitude 15 5511 offers extensive security features and long battery life.

Ultimately, it's the size of the Latitude 15 that will deter some users from buying it. Although the 15-inch device doesn't weigh much, it's anything but a small laptop. In return, it offers many security features and an all-around stable case. Therefore, the Dell Latitude 15 5511 is well suited for productive work and occasional transportation.

Price and availability

The Dell Latitude 15 5511 is available now in our test configuration. You can find it, for example, on Amazon for a current price of $1,690.99.

I carried out my first IT experiments with a 386-based system and a whole 4 MB RAM. This was followed by work on various PCs and laptops that I maintained and repaired for friends and acquaintances. After training to become a Telecommunications Systems Technician and gaining a few years of experience, I graduated with a Bachelor’s degree in Industrial Engineering. Currently, I pursue my fascination for IT, technology, and mobile devices by writing reviews and articles for Notebookcheck. I have also worked for Gamestar, Netzwelt, and Golem, among others.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
