HP EliteBook 840 G6 is part of the latest generation of EliteBook 800 laptops. Traditionally, the EliteBook brand has been known for its extreme reliability and longevity in terms of degradation and moral aging.
Interestingly, this laptop doesn’t differ a lot from its predecessor from the fifth generation 800 devices. While it retains the aluminum chassis, it now embodies the Whiskey Lake processors from Intel. Security-wise there are the HP Secure Start and Secure Click (not very creative from HP, we know), and furthermore, you can pick from several vPro-labeled CPUs.
Display-wise there is a 4K IPS option, which is probably not going to be the most popular one, as it will significantly increase the cost of the EliteBook 840 G6. Nevertheless, we did manage to get our hands on a 1080p IPS version, which has better support through apps’ UI.

HP EliteBook 840 G6 - Specs
All HP EliteBook 840 G6 configurations
See all HP EliteBook 840 G6 review – one for the classy business people out there configurationsWhat’s in the box?
Inside of the package, we unsurprisingly found an HP EliteBook 840 G6. Paying company to the laptop, there are several manuals and guides, as well as a 45W charging brick (the Radeon 550X version should come with a 65W one).
Design and construction
This device’s design has taken inspiration from both the ultrabook and the industrial family of laptops. its body is built entirely out of aluminum, which gives it the premium cold touch when you first make contact with the surface. As you can see from the images, the lid has lost the plastic stripe, meant for the LTE antenna.
Honestly, with the latest update of the ProBook series, the visual differences between the two have decreased greatly. In addition to looking stunning, the EliteBook has a profile of only 17.9mm and weighs 1.48 kg. So yes, it is very easy to handle around, without any strains in your arms.
Opening its lid with a single hand is possible and in terms of resistance to flex, this one is a champ. Well, certainly, there is some flex when you bend it, but it is ever so subtle, and you end up moving the entire device, rather than flexing the lid itself.
Right above the display, you are going to see two circular cut-outs that are hiding the IR sensors for face recognition. However, this is not the only biometric sensor on this laptop.
The other one is located on the bottom right corner of the base and it is the fingerprint reader. Above it, you can see a spill-resistant keyboard that has a nice key travel and decent tactile feedback. Moreover, it is backlit and features a nipple – just above the “B” key. Its buttons are placed above the glass-fitted touchpad, which itself feels fast and accurate.
Then, at the bottom plate, there is only one, though a rather big grill, which is clearly meant for ventilation. While the hot air escapes from the left side to the annoyance of left-handed people, the speakers are nowhere to be found on the bottom. This is because, they have their place at the base – just above the keyboard. Plus, they have Bang & Olufsen branding, which means they are tuned from the Audio company.
Ports
Since it is a typical business machine, the EliteBook 840 G6 is loaded with I/O. On the left, you will find a USB Type-A 3.1 (Gen. 1) port with a charging function, as well as the optional Smart Card reader. Looking on the right, there is a charging plug and a Thunderbolt port, either of which can be used for charging (depending on the charger, of course). Then, there is a docking connector, as well as an RJ-45 and HDMI connectors, followed by another USB Type-A 3.1 (Gen. 1) port, an audio jack, and an optional SIM card tray.
Disassembly, upgrade options and maintenance
This device has only 8 Phillips-head screws that hold its bottom panel in place. Moreover, these 8 screws don’t detach from it, when you unscrew them, meaning you will have a hard time losing them.
In terms of cooling, the laptop features a single heat pipe design, which is very common in this type of laptops.
Thankfully, the notebook features two RAM DIMMs that support up to 32GB of DDR4 memory. Additionally, there is an M.2 PCIe x4 slot on their left.
Finally, on the bottom-most portion of the insides, you can see the 50Wh battery pack, used in this device.
Display quality
HP EliteBook 840 G6 has a Full HD IPS display, model number Chi Mei CMN14E0. Its diagonal is 14″ (35.56 cm), and the resolution – 1920 х 1080. Additionally, the screen ratio is 16:9, the pixel density – 157 ppi, their pitch – 0.161 x 0.161 mm. The screen can be considered Retina when viewed from at least 56 cm (from this distance, the average human eye can’t see the individual pixels).
It has excellent viewing angles. We have provided images at 45 degrees to evaluate quality.
The maximum measured brightness is 444 nits (cd/m2) in the middle of the screen and 417 nits (cd/m2) average across the surface with a maximum deviation of 12%. The Correlated Color Temperature on a white screen and at maximum brightness is 6900K (average) – colder than the 6500K optimum for sRGB. The average color temperature through the grey scale before profiling is 6900K, as well.
In the illustration below you can see how the display performs from a uniformity perspective.
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 (a maximum tolerance of 2.0 ). The contrast ratio is very good – 1330:1 (1230:1 after profiling).
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. 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 yellow dotted line shows HP EliteBook 840 G6’s color gamut coverage.
Its display covers 94% 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 HP EliteBook 840 G6 with the default settings (left), and with the “Gaming and Web design” profile (right).
The next figure shows how well the display can reproduce 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 = 21 ms
Health impact – PWM / Blue Light
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.
HP EliteBook 840 G6’s display backlight uses PWM to adjust the level of its brightness up until 118 nits. Additionally, the frequency of the flickers is high enough, so that it doesn’t have a harmful effect on your eyes in this aspect.
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.
Conclusions
HP EliteBook 840 G6 has a Full HD IPS panel with good contrast, comfortable viewing angles, great maximum brightness, and wide color coverage.

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
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
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
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.
Sound
HP EliteBook 840 G6 produces a decent sound. Its low, mid and high tones are clear of deviations.

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. HP has equipped the EliteBook 840 G6 with a 50Wh battery pack.
It is able to output around 16 hours of Web browsing and 12 hours and a half of video playback.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
We use F1 2017’s built-in benchmark on loop in order to simulate real-life gaming.

It is obvious from the chart above that the EliteBook 840 G6 aims at the comfort and business usability when it comes to its thermal configuration. It starts the stress test comfortably at 3.11 GHz but then quickly goes down to the 2.20 GHz region for the remainder of the torture. However, the temperatures at the end are 67C, while the fan itself is barely audible.
Comfort during full load
With the fan spinning with low RPM and the base of the device never exceeding 36C, the experience is not ruined even in extreme working conditions
Verdict
Here we are at the end of this review. The HP EliteBook 840 G6 is one of the stable machines on the business market today. We didn’t really encounter any problems throughout our review and this is one of the main reasons we liked the machine. It has a great design, comfortable keyboard, and touchpad, as well as pretty extended I/O with Thunderbolt support and docking capabilities via a dedicated port.
Moreover, apart from the high price tag, we can’t really think of something wrong about the EliteBook 840 G6. We found out that the 1080p IPS panel (Chi Mei CMN14E0) of this device has great maximum brightness, comfortable viewing angles, and a very good contrast ratio. In addition to that, the color coverage is pretty wide (94% of sRGB), and while it uses PWM to adjust its brightness levels until 118 nits, it does it with a very high frequency, that is effectively not harmful to your eyes in this aspect. Something for the designers out there – the laptop has a decent color accuracy out of the box, however, when you install our Gaming and Web design profile, you can bring the Average dE down to 1.0.
Next – battery life. One word – exceptional. We got around 16 hours of Web browsing and 12 hours and a half of video playback from the 50Wh battery pack. Truly that’s a sign of a good optimization and the overall effectiveness of the Whiskey Lake processors. By the way, the laptop also performs really well, especially in a day-to-day workload. At the same time, it is clear that this won’t be exactly a video editing machine, as the frequency is not that high during long extreme workloads. On the bright side, the temperatures are really low – both the CPU one and the outer shell one.
If we compare this laptop side by side with the Dell Latitude 5400, there are some huge differences – mostly on the outside. Basically, both of them would do the job, but the EliteBook 840 G6’s design gives it the upper hand. At least in terms of SWAG.
Pros
- Classy aluminum shell
- Quiet and cool during full load
- Wide variety of I/O options
- Super long battery life
- Wide color coverage (94% of sRGB) and great color accuracy thanks to our Gaming and Web design profile (Chi Mei CMN14E0)
- Reaches high maximum brightness (444 nits) and doesn’t use aggressive PWM for brightness adjustment (Chi Mei CMN14E0)
Cons
- A little pricey
