Mobile workstations are growing in popularity every year. This makes us extremely excited to test such laptops, as they differ quite drastically in the usage to the more convenient multimedia devices or the extremely powerful gaming solutions.
This is exactly what a device we have with us right now. However, the HP ZBook 15u G6 is nothing like the Lenovo ThinkPad P52 for example. As its name suggests, it houses a slightly less powerful, but a lot more efficient hardware (if you want the maxed-out versions HP has the ZBook 15 for you). For the main computing, there is a Whiskey Lake Core i5-8265U or a Core i7-8565U, while the graphics load is given to the AMD Radeon Pro WX3200. Here, both the CPU and the GPU are evolutions of the last-year model.
In addition to that, HP has loaded the laptop with some very neat goodies – a dedicated docking port, a fingerprint reader and even an IR face recognition system. On top of that, the ZBook 15u G6 complies with the MIL-STD-810G standard and has a spill-resistant keyboard.

Specs Sheet
HP ZBook 15u G6 - Specs
All HP ZBook 15u G6 configurations
What’s in the box?
Its package resembles nothing fancy on the outside, nor on the inside. The laptop is protected by a plastic antistatic bag, while the 65W charger (or 45W in some configurations) is located in a separate compartment.
Design and construction
So in terms of a footprint and overall build, the HP ZBook 15u G6 is quite unchanged from its predecessor. However, on the brights side, gone is the top plastic stripe that acted like an LTE antenna. The laptop also retained the 18 mm profile and 1.77kg weight, which makes it an extremely portable device, especially considering it is labeled as a mobile workstation.
Moving to the lid of the device, we first started to open it with a single hand, and to our surprise, the results were kind of hit or miss. Perhaps at 50% of the times, we were easily able to open the lid singe handed while the rest of the times, the base has lifted from the ground. If you take a look at the camera assembly, there are two circular modules on either side of it. They are IR blasters that help with the IR face recognition this laptop offers. As of the performance – it is fast and accurate, even in low light conditions.
Next, there is the base. Similarly, to the last-year model, it is not only home to the keyboard and the touchpad, but also to the speakers (which are hidden beneath the rather long grill) and a fingerprint reader. While, the reader itself is not very satisfying, as it is significantly slower than the IR face recognition, we were pretty happy with the keyboard and the touchpad.
First, the key travel is sufficient, and the actual feedback each key gives is very uniform and clicky. Add to that a fairly bright backlight and an anti-spill feature and you get a very decent keyboard experience. But wait! There’s more! Not only it features full-sized Number Pad keys, but it also has a proprietory nipple – quite similarly to Dell’s Latitudes, Lenovo’s ThinkPads and HP’s own EliteBook series. Despite that, we would definitely stick to the touchpad, which has a glass surface, dedicated mouse buttons (although they are meant for use with the nipple) and an NFC connectivity beneath it.
Since the speakers are right above the keyboard, on the bottom side you will only see a grill for ventilation, while the hot air will come out of the left side of the laptop.
Ports
On the left side of the laptop, you are going to see a single USB Type-A 3.1 (Gen. 1) port with a charging function and a Smart Card slot. That means that the I/O is predominantly located on the right side. There you will find the charging plug, a Thunderbolt port, as well as a proprietary docking port, an RJ-45 and HDMI connectors, and another USB Type-A 3.1 (Gen. 1) port.
Disassembly, upgrade options and maintenance
Once again, this is a pretty easy device to teardown. The backplate comes off when you unscrew the 10 Phillips head screws and then pry it from the chassis.
As our unit was configured with a dedicated GPU, there are two heat pipes in use for the cooling. What is kind of unpleasant is that the CPU and the GPU are placed very close to each other, which may impede the effectiveness of the cooling system.
Just beneath the two chips, there are two RAM DIMMs that are able to hold up to 32GB of DDR4 memory, while on their left, you can see the M.2 PCIe x4 NVMe drive slot.
Battery-wise there is a 56Wh unit, which looks a little small for the packaging. No, that 56Wh is not enough, but we certainly feel that HP could have fitted more.
Display quality
HP ZBook 15u G6 has a Full HD IPS panel, with a model number CMN150D. Its diagonal is 15.6″ (39.62 cm), and the resolution – 1920 х 1080. Additionally, the screen ratio is 16:9, the pixel density – 142 ppi, their pitch – 0.18 x 0.18 mm. The screen can be considered Retina when viewed from at least 60 cm (from this distance, the average human eye can’t see the individual pixels).
Viewing angles are excellent. We provide images at different angles.
The maximum measured brightness is 284 nits (cd/m2) in the middle of the screen and 261 nits (cd/m2) average across the surface with a maximum deviation of 13%. The Correlated Color Temperature on a white screen and at maximum brightness is 6520K (average) – matching the 6500K optimum for sRGB. The average color temperature through the grey scale before profiling is 6460K.
In the illustration below you can see how the display performs from uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 60% Brightness (White level = 145 cd/m2, Black level = 0.1 cd/m2).
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 impressive – 1480:1.
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 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 ZBook 15u G6’s color gamut coverage.
Sadly, its display covers just 54% 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 ZBook 15u G6 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 = 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 ZBook 15u G6’s display uses PWM to adjust its brightness until 75 nits. Moreover, the pulsations have a very high frequency, which makes it comfortable for long working periods.
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 ZBook 15u G6’s display has an IPS panel with a Full HD resolution, comfortable viewing angles, and good contrast ratio. While it doesn’t use an aggressive form of PWM to adjust its brightness, the limited color coverage can be considered as a disadvantage.

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
Health-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 ZBook 15u G6’s speakers are decent. Their low, mid and high frequencies are clear of deviations.
Drivers
All drivers and utilities for the ZBook 15u G6 can be found on HP’s official web page: https://support.hp.com/us-en/drivers/selfservice/hp-zbook-15u-g6-mobile-workstation/22892886
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. This laptop has a 56Wh battery pack onboard.
With it, the ZBook 15u G6 achieved exceptional battery life – more than 14 hours of Web browsing and a little bit less than 15 hours 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.
CPU options
As this is a mobile workstation laptop, it is expected to see a mobile chip operating inside of it. The two options for you are the Core i5-8265U and the Core i7-8565U – both 4-core/8-thread solutions.

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.

Comfort during full load
In terms of noise, the laptop doesn’t get too loud under heavy load. Additionally, the hottest spot we measured was about 43C and unsurprisingly – it was the nipple.
Verdict
Putting it straight, the HP ZBook 15u G6 is not really a significant upgrade over the ZBook 15u G5. In fact, it is pretty much the same device with a refreshed processor and GPU. While to some extent both of them work better than their previous versions, the differences are just too small.
Especially, when it comes to the CPU. Last year, we saw a significant underperformance from the Core i7-8550U. Now, things are just the same, with the processor not being utilized fully (and we all know the potential of Core i7-8565U). Nevertheless, the ZBook 15u G6 still stays a very respectable piece of hardware.
The upgradability is good with the two RAM DIMMs and the single M.2 storage slot. Despite the lack of a 2.5″ SATA drive support, we were happy to see four PCIe lanes for the M.2 drive, which makes it support extremely high speeds. Moreover, the laptop is equipped with a Thunderbolt connector.
HP ZBook 15u G6’s display has an IPS panel with a Full HD resolution, comfortable viewing angles, and good contrast ratio. While it doesn’t use an aggressive form of PWM to adjust its brightness, the limited color coverage can be considered as a disadvantage.
So, what is its greatest strength? – definitely the battery life. It goes to 14 hours of Web browsing and around 15 hours of video playback.
In terms of the business usability – you have a great keyboard and touchpad, with the former having long keystrokes and tactile feedback, and the latter being super smooth and housing an NFC antenna inside. Additionally, the laptop is equipped with a fingerprint reader and an IR face recognition system, to please those security freaks. If we have to be completely honest (and we do) the fingerprint reader is far from the best in the industry – it is pretty accurate, but its speed is mediocre.
We would gladfully give this device an Editor’s choice award if it wasn’t for the sub-par performance – especially in longer tasks. While the CPU is the bomb when it comes to short tasks, like editing an image in Photoshop or doing some Excell maths, as soon as you try to render a video, the clock speeds plummet drastically. It is the same with the graphics card – at the beginning of a benchmark it performs really nice, but when you go five or more minutes into the test, its performance gets halved.
Pros
- Thin and light form factor
- Packed with security and usability features
- Comfortable input devices
- Astounding battery life
- IR face recognition and fingerprint reader onboard
- Thunderbolt support and PCIe x4 M.2 slot
- Doesn’t use aggressive PWM to adjust its brightness
- Has a good contrast ratio and comfortable viewing angles
Cons
- Underperforming hardware
- Covers only 54% of sRGB

You do not have display parameters in many reviews. It is becoming a rule. Why is such a review I ask? The display is one with the key elements of a laptop after all!
What about the display?
Totally agree with JohnST – unless there is some reference to the percentage coverage of sRGB / AdobeRGB the review is pointless for anyone requiring visual colour accuracy.
After three months, will you fill in the display parameters? It’s a joke, isn’t it?
Actually, It is not a joke. We were extremely busy in the past several months to provide you with the highest quality content, we could deliver.
So now, perhaps if you reload the page, you can read the full review, updated with its proper display portion.
