Dell Latitude 3400 Laptop Review: An affordable business laptop with long battery life

Sascha Mölck, 👁 Sebastian Jentsch, Felicitas Krohn (translated by Alex Alderson), 10/02/2019

A business beginner. The Dell Latitude 3400 scores well for its long battery life, good keyboard and extensive ports. However, its dim and low-contrast display will not set the world alight, despite it being a matte IPS panel. Read on to find out how this 14-inch business laptop gets on in our tests.

The Latitude 3400 is one of Dell's entry-level 14-inch business laptops and succeeds the Latitude 3490 despite its name. Our review unit currently retails for between €550 (~$601) and €600 (~$656), making it the cheapest device in the series that Dell currently offers. We shall compare the Latitude 3400 against the HP ProBook 445 G6 and 440 G6, along with the Lenovo ThinkPad E490 and E495.

Case & Connectivity - Dell includes plenty of ports

The Latitude 3400 has a black plastic chassis, which for the most part has a matte and roughened finish. The sides are plastic too, but Dell has opted for a glossy and smooth finish instead. Our review unit is well-made overall and does not have any serious stability or build issues. Dell installs the battery beneath the bottom plate as is the case with most modern laptops, so you must disassemble the laptop to access it.

Dell equips the device with three USB Type-A ports, specifically two USB 3.2 Gen1 and one USB 2.0, along with one USB 3.2 Gen1 Type-C port. The latter supports DisplayPort too, but you must use a separate adapter to utilise this functionality. The Latitude 3400 has three video outputs if one includes DP over Type-C, as Dell has included HDMI and VGA ports too. The Type-C port also supports USB Power Delivery (PD) for charging the Latitude, while there is Gigabit Ethernet onboard if you need a wired internet connection.

There is also an SD card reader, but it is one of the slowest of its kind. The one in our review unit averaged 32.3 MB/s when copying large blocks of data, which dropped to 23 MB/s when transferring 250 5 MB JPG files. We tested the card reader using our Toshiba Exceria Pro SDXC 64 GB UHS-II reference card, which is capable of much higher transfer speeds than the Latitude can manage.

Finally, Dell has integrated an Intel Wireless AC 9560, which supports up to IEEE 802.11 ac Wi-Fi as its name suggests. Our review unit achieved good transfer speeds during our iperf3 Client Wi-Fi tests, although please keep in mind that we conducted these tests with the Latitude next to our reference router and removed all other Wi-Fi connected devices from the immediate vicinity too.

Input Devices - A backlit Latitude

Dell equips the Latitude 3400 with a backlit chiclet keyboard, which consists of flat keys that have a slightly roughened texture. The keys in our review unit have short strokes and clear pressure points, of which we are fans. The keyboard deck gives way a bit while typing, but not disturbingly so during our tests. The backlighting has two levels that can be cycled with a function key, which is handy. Overall, Dell has equipped the Latitude 3400 with a decent keyboard that delivers in all areas.

There is also a multi-touch trackpad that measures around 10.5 x 6.5 cm (~4.1 x 2.6 in), which is large enough to perform multi-finger gestures on in our opinion. The trackpad has a smooth texture to it that we found easy to move our fingers across and perform swiping gestures. The one in our review unit remains accurate into its corners too, and integrates two mouse buttons, which have short strokes and clear pressure points.

Display - IPS and matte, but dim and washed out

Sub-pixel array
Sub-pixel array

As we mentioned earlier, Dell equips the Latitude 3400 with a 14-inch 1080p panel that it has given a matte finish. The IPS panel achieved an average maximum brightness of 226.9 cd/m² according to X-Rite i1Pro 2 and a contrast ratio of 500:1, which are both too low for our liking. We expect modern laptops to reach at least 300 cd/m² and 1,000:1, so the Latitude 3400 falls well short in both regards. However, none of our comparison devices meet these thresholds, so the Latitude 3400 is in good company in that regard. Our comparison devices all have more contrast-rich displays than the Latitude 3400 does, though.

Unfortunately, the Latitude 3400 also uses the eyestrain and headache-inducing pulse-width modulation (PWM) to regulate luminosity at 90% brightness and below. The panel in our review unit flickers at 1,000 Hz, which may be high enough to avoid causing issues for most people. We would still recommend trying out the Latitude 3400 before you buy it if you are PWM sensitive, as the PWM frequency may be low enough to cause you the issues that we described.

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
42 ms ... rise ↗ and fall ↘ combined↗ 28 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. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey

In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 65 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.5 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9331 (minimum: 43 - maximum: 142900) Hz was measured.

Dell has done a good job of factory calibrating the display, with our review unit only just missing our ideal value of 3 for DeltaE 2000 colour deviations. The display only covers 59% of the sRGB colour space and 38% of AdobeRGB though, making it colour accurate enough for only hobbyist photo and video editing.

The IPS panel also has stable viewing angles, so you should have no issues with reading the display from acute angles. However, while the matte finish diffuses reflections, the Latitude 3400 cannot get bright enough to overcome bright sunshine. Its meagre contrast ratio makes our review unit look washed out in bright sunshine too, as the photos below demonstrate. Hence, the Latitude 3400 is best suited as an indoor-only laptop.

Performance - An entry-level office laptop

In short, the Latitude 3400 is powerful enough for all general Office and Internet-based applications. Dell currently sells our review unit for between €550 (~$601) and €600 (~$656), but it also offers other configurations should you need more powerful hardware.

Processor

At the heart of our review unit is an Intel Core i3-8145U, a dual-core processor based on the company's Whiskey Lake architecture. The CPU has a 2.1 GHz base clock and can use Intel Turbo Boost to increase its clock speed up to 3.7 GHz on two cores or 3.9 GHz on one core. The Core i3-8145U supports Intel Hyper-Threading too, allowing it to execute up to two threads per core simultaneously.

The Core i3-8145U temporarily maintains 3.7 GHz during multi-threaded benchmarks such as Cinebench R15 Multi 64Bit, but clock speeds quickly drop to between 3.1 and 3.2 GHz. However, the device can maintain between 3.7 and 3.9 GHz in the corresponding single-threaded benchmark. The Latitude 3400 does not throttle CPU performance on battery either, so these scores represent what the device should achieve regardless of whether it is connected to the mains.

We also checked how well the CPU performs under sustained load by running CB R15 Multi 64Bit on a loop for at least 30 minutes. Our review unit throttles slightly after the first benchmark run-through, but it then stabilises at around 310 points for the remainder of the loop save for one aberration.

We expected more from the Core i3-8145U here, though. A device the size of the Latitude 3400 should have no issues with cooling a dual-core ultra-low-voltage (ULV) CPU, but our review unit cannot keep it at peak clock speeds, which is rather underwhelming.

System Performance

Our review unit performed well in daily use, which PCMark reinforces. We did not encounter any performance issues in daily use, but the Latitude 3400 would benefit from dual-channel mode, with our review unit running in single-channel mode. Switching to the former would require adding a second, and identical, SODIMM module.

The Latitude 3400 has two SODIMM slots

Storage Devices

Dell has equipped our review unit with a 256 GB Western Digital SN520 SSD, of which around 198 GB was free when we first booted the device. The M.2-2280 drive achieved solid transfer speeds during our tests and outperformed most of the SSDs in our comparison devices in CrystalDiskMark.

Graphics Card

Dell has not equipped the Latitude 3400 with a dedicated GPU, so our review unit must rely on the UHD Graphics 620 that Intel integrates within the Core i3-8145U instead. The GPU supports DirectX 12, can clock up to 1,000 MHz and has a hardware video decoder that can handle tasks such as streaming from Netflix with ease. Our review unit performed just as expected in 3DMark, but it could achieve better scores if it were running in dual-channel mode.

Gaming Performance

The UHD Graphics 620 is not powerful enough to play modern triple-A games, but you should have no issues with older titles such as "BioShock Infinite" or "League of Legends". However, our review unit can only render the former at playable framerates in 720p and on the lowest graphics preset, so the game will not be that pleasing on the eye. Again, dual-channel would improve framerates, but not massively so.

Emissions - Acceptable fan noise and surface temperatures

Fan Noise

Our review unit often runs silently when idling, but its single fan occasionally reaches 32.8 dB(A) even during menial tasks. The fan peaked at 38.1 dB(A) during our stress tests too, but this does not sound overly noisy to our ears.

Temperature

System information during a combined FurMark and Prime95 stress test
System information during a combined FurMark and Prime95 stress test

We subjected our review unit to a combined FurMark and Prime95 stress test, which we left running for at least an hour to see how it fared under extreme load conditions. The Latitude 3400 performed just as well on battery as it did on mains power, during which its CPU initial operated at between 3.4 and 3.7 GHz. However, it plummeted to 1.2 GHz after a few moments, a level that it maintained for the remainder of the test. By contrast, the GPU always remained at around 900 to 950 MHz, but that is probably because the components share their thermal design power (TDP). In practical terms, this means that the CPU and GPU are unable to operate at peak clock speeds simultaneously. You should not experience this degree of throttling, even when gaming though, as our stress test pushes devices to their limits.

Most of the Latitude 3400 remained cool to the touch even during our stress test, with the palm rest never exceeding 27 °C (~81 °F). Only one area reaches 40 °C (~104 °F), so the device should never feel too hot to hold even if you are pushing it to its limits. Expectedly, the Latitude 3400 runs more coolly when idling.

Speakers

Dell equips the Latitude 3400 with stereo speakers that it has placed facing downwards at the front of the device. The ones in our review unit output audio that sounds rather thin and tinny with a complete lack of bass. They are also overly quiet, so we would recommend using external audio equipment like headphones or speakers where possible.

Power Management - Acceptable power consumption and great battery life

Power Consumption

The Latitude 3400 consumed between 2.4 W and 47 W when switched on during our tests, which is reasonable for a dual-core business laptop. However, it can only maintain the latter wattage for a few seconds and averages 31 W under sustained load. Dell includes a 65-W charger in the box, so the Latitude 3400 should always keep charging even if it is being pushed to its limits.

Battery Life

The Latitude 3400 has a 56 Wh battery, which lasted for an impressive 9:44 hours in our practical Wi-Fi battery life test. We conduct this test by running a script that simulates the load required to render websites. We also set devices to the Balanced Windows 10 power profile, disable all power-saving features and set the display to approximately 150 cd/m². Only the Latitude 3490 lasted longer than the Latitude 3400 of our comparison devices, for reference.

Verdict

The Dell Latitude 3400 (FPD13) laptop review. Test device courtesy of notebooksbilliger.de.
The Dell Latitude 3400 (FPD13) laptop review. Test device courtesy of notebooksbilliger.de.

The Dell Latitude 3400 is a mundane business laptop, especially when configured with an Intel Core i3-8145U processor. However, it is powerful enough for all general office and internet-based tasks. It also never gets too hot or noisy.

The inclusion of a fast NVMe SSD ensures that the system runs smoothly too, although you could swap this for a larger capacity drive should you need to do so. You would need to disassemble the device to do this.

The Dell Latitude 3400 is a solid and affordable 14-inch business laptop that should not let you down while at work.

We are fans of the keyboard and trackpad too, as we are with the battery life. Likewise, the Latitude 3400 has a good selection of ports, including USB Type-C that supports DisplayPort and USB PD. However, its dim and low-contrast display disappointed us, while the slow card reader and 12-month standard warranty are a shame too. Overall, the Dell Latitude 3400 is a decent office laptop that will appeal to those who are on a limited budget.
