Dell’s Latitude or Lenovo’s ThinkPad. This is an age-old question, which we are probably not going to answer today. On the other hand, we are going to tell you more about the Latitude 15 3510, and see whether the budget nature of the notebook is something that would attract more people, or the quality of execution will actually drive them away.

Interestingly, when you look at the official listing on Dell’s website, you will see statements like “World’s smallest 15-inch essential business notebook” and mentions of the “Dell Optimizer AI”, which contrary to the expectations is not a superhuman robot from the future, but something more like a task priority manager.

Also, it’s worth saying that Dell still offers a business notebook in 2020 with a 768p TN display option, which is an utter disgrace. Thankfully, you have a choice, and they provide a much more adequate solution in the face of a 1080p IPS panel – more on that later.

So let’s dive in and see what you get for your precious money.

What’s in the box?

Inside the package, we found a 65W power brick, as well as some paper manuals, and an 8GB flash drive, containing all of the drivers for your new notebook.

Design and construction

When you see the number 3 in front of a four-digit Latitude name, you shouldn’t expect premium build quality. And to no surprise, this is what we found here. The entire body of the notebook is built out of plastic. Most of it is matte and has a rough finish, so fingerprints won’t be a problem, while the edges are all glossy. In terms of dimensions, the notebook is in fact really thin and light, considering its purpose – it weighs 1.79 kg and has a profile of 18mm. And in terms of structural integrity, the laptop is nothing to write home about. The body is twisty, and definitely not strong enough to endure a semi-high fall. Also, there is a lot of popping sounds coming from the lid when you twist it.

Speaking of the lid, you won’t be able to open it with a single hand. On the bright side, its side bezels are pretty thin, and the top one houses an HD camera.

We feel like we’re being a bit too harsh on this notebook, but you should know things as they are before making a purchase, right? Well, in this tone of talking, the keyboard is not very impressive as well. Its travel is short and the feedback is mushy, which results in a relatively uncomfortable experience. On the bright side, there is a backlight, and you have a NumberPad section at your disposal. Also, you can configure the Latitude 15 3510 with a fingerprint reader, embedded into the Power button.

Also, we really like the simple design of the base and the laptop in general. However, the touchpad is not amongst the things we did enjoy while using the device. First, you need to make sure you install all of the drivers, and specifically, the Serial I/O one. Then again, the tracking is decent, but we’ve seen a lot better on cheaper machines.

Lastly, if you turn the laptop upside down, you will see the ventilation grills, as well as the speaker cutouts. And in contrast to the Latitude 5000 series, the heat dissipation happens from in between the base and the lid.

Ports

On the left side of the laptop, you’ll find the barrel-style Power plug and its status LED. Next, there is an HDMI 1.4 connector, a USB Type-A 3.2 (Gen. 1) port, as well as a USB Type-C 3.2 (Gen. 1) port with Power Delivery and DisplayPort 1.2 capabilities. Respectively on the right, there is an RJ-45 connector, followed by a USB Type-A 3.2 (Gen. 1) port and a USB Type-A 2.0 port for quick Stonehenge connection, then an Audio jack, and a MicroSD card reader. Additionally, this model has an optional LTE capability, and the SIM card slot would be placed right after the MicroSD card slot.

Disassembly, upgrade options and maintenance

Getting inside this notebook requires the removal of 8 Phillips-head screws. Thankfully, they stay attached to the bottom panel, so you won’t lose them. Anyway, the next thing you need to do is to pry the panel away with a plastic tool. We found it easier to gently lift the base and start the prying process in a semi-opened position.

After you lift the panel away, you will notice the cooling solution, which employs a single heat pipe, as well as a fan, which is relatively small in size.

On the bright side, Dell provides you with quite the upgrade options. There are two RAM SODIMM slots, which support up to 32GB of DDR4 memory in total. Storage-wise, you can put a 2.5-inch SATA device, thanks to the included connector and screws, and there is also the option of an M.2 PCIe x4 drive.

As you can see, our unit features a rather modest 40Wh battery pack. However, this device is sold with a 53Wh unit, as well.

Display quality

Dell Latitude 15 3510 has a Full HD IPS panel with a model number BOE T1WD3-NV15N3D (BOE0819). Its diagonal is 15.6″ (39.62 cm), and the resolution 1920 х 1080 pixels. The screen ratio is 16:9, and we are looking at a pixel density of – 142 ppi, and a pitch of 0.18 х 0.18 mm. The screen turns into Retina when viewed at distance equal to or greater than 60cm (24″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop).

Its display has excellent viewing angles. We offer images at 45° to evaluate image quality.

The measured maximum brightness of 256 nits in the middle of the screen and 250 nits as an average for the whole area, with a maximum deviation of 5%. The Correlated Color Temperature on a white screen is 6830K – slightly colder than the sRGB standard of 6500K.
In the illustration below you can see how the display performs from a uniformity perspective. In other words, the leakage of light from the light source.

Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work. The contrast ratio is good – 1020:1.

To make sure we are on the same page, we would like to give you a little introduction to 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 an 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 yellow dotted line shows Dell Latitude 15 3510’s color gamut coverage.

Its display covers 50% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.

Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.

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 “Design and Gaming” profile.

Below you can compare the scores of Dell Latitude 15 3510 with the default settings (left), and with the “Gaming and Web design” profile (right).

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 and Web Design” 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 (Gaming capabilities)

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

We recorded Fall Time + Rise Time = 29 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.

Sadly, the Dell Latitude 15 3510 uses PWM for all brightness levels, except for the maximum. Additionally, the flickerings have a low frequency which is a downside, as well.

Blue light emissions

Installing 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 dedicated article on Blue Light.

Conclusion

Dell Latitude 15 3510’s IPS panel has a Full HD resolution, comfortable viewing angles, and good contrast ratio. Sadly, it covers only half of the colors on the Internet, and it uses aggressive PWM for all brightness levels, except the maximum. Thankfully, though, our Health-Guard profile completely eliminates this issue.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia’s products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work - screen profile

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming - screen profile

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.

Health-Guard - screen profile

Health-Guard

THealth-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

All

Sound

Actually, Dell Latitude 15 3510’s speakers produce a very well balanced and loud sound. Additionally, the low, mid, and high tones are clear of deviations.

Drivers

All of the drivers and utilities for this laptop can be found here: https://www.dell.com/support/home/en-us/product-support/product/latitude-15-3510-laptop/drivers

Battery

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. Our model featured a 40Wh battery pack. It was able to deliver 9 hours and 24 minutes of Web browsing and 8 hours and 51 minutes of video playback.

CPU options

Interestingly, the Latitude 15 3510 comes with an underdog like the Celeron 5205U, Core i3-10110U, Core i5-10210(10310)U, and the reasonably potent Core i7-10510U.


Dell Latitude 15 3510 CPU variants

Here you can see an approximate comparison between the CPUs that can be found in the Dell Latitude 15 3510 models on the market. This way you can decide for yourself which Dell Latitude 15 3510 model is the best bang for your buck.

Note: The chart shows the cheapest different CPU configurations so you should check what the other specifications of these laptops are by clicking on the laptop’s name / CPU.


GPU options

On the other hand, the graphics card choice is pretty sparse. You can either get only the integrated Intel UHD Graphics or the NVIDIA GeForce MX230.

Temperatures and comfort

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average core frequency (base frequency + X); CPU temp.

Intel Core i3-10110U (15W TDP) 0:02 – 0:10 sec 0:15 – 0:30 sec 10:00 – 15:00 min
Dell Latitude 15 3510 3.57 GHz (B+70%) @ 99°C 3.21 GHz (B+53%) @ 99°C 2.89 GHz (B+38%) @ 94°C
HP 15 (15-dw1000) 2.79 GHz (B+33%) @ 75°C 2.72 GHz (B+30%) @ 76°C 2.68 GHz (B+28%) @ 68°C
Dell Vostro 3590 3.32 GHz (B+58%) @ 95°C 3.27 GHz (B+56%) @ 97°C 2.73 GHz (B+30%) @ 84°C

Apparently, Dell is trying to murder the Core i3-10110U as soon as possible. While the laptop remains pretty cool on idle, you can see how things change when we applied an extreme workload.

Comfort during full load

Its fan is not extremely loud, even when it’s spinning like crazy. However, the 48C on the outside is quite worrying. Although, these temperatures are only seen in the top left part of the keyboard, with the rest remaining relatively cool.

Verdict

Well, well, well… Honestly, we were not expecting so many corners to be cut, when we first got the notebook. But after thorough testing, and even in our first minutes with it, we saw stuff like poor build quality, executed with cheap materials. Also, the keyboard is one of the bad units out there, with its short key travel and mushy feedback.

Additionally, the cooling solution of the device is ineffective, even with the Core i3-10110U. Thankfully, Dell has put decent speakers on the Latitude 15 3510, and some models come with an optional fingerprint reader. And what is more important for a budget workhorse – it comes with two RAM SODIMM slots, supporting up to 32GB of DDR4 memory, and it has two storage options, thanks to its M.2 slot and the 2.5-inch SATA drive bay. In fact, Dell is kind enough to supply the connector and four screws, that will help you mount and connect your SATA device.

Dell Latitude 15 3510’s IPS panel (BOE T1WD3-NV15N3D (BOE0819)) has a Full HD resolution, comfortable viewing angles, and good contrast ratio. Sadly, it covers only half of the colors on the Internet, and it uses aggressive PWM for all brightness levels, except the maximum. Thankfully, though, our Health-Guard profile completely eliminates this issue.

Yet again, the budget nature of the Full HD display is something expected, but we strongly recommend getting the aforementioned profile.

Nevertheless, the laptop boasts more than 9 hours of Web browsing and just 10 minutes shy of the same benchmark during video playback. And all of this happens on the smaller – 40Wh battery. Naturally, the larger unit (53Wh) should deliver a higher number.

So, should you pick this laptop over the ThinkPad E15 for example? If you value the looks of your notebook – yes. But if the usability and future-proofness are on the table for you, then the Latitude 15 3510 might not be as bad of a choice as it seems.

Pros

  • Great upgradability
  • Good battery life
  • MicroSD card slot and an optional Wi-Fi 6 support
  • Optional fingerprint reader

Cons

  • Uses aggressive PWM for all brightness levels (our Health-Guard profile fixes that) (BOE T1WD3-NV15N3D)
  • Unexpectedly hot under extreme load
  • Covers only half of the colors in the sRGB gamut (BOE T1WD3-NV15N3D)
  • Soft and mushy keyboard
