HP ZBook Power 16 G11 review – All-Metal Workstation with Quiet Fans and Capable Cooling

The ZBook Power 16 G11 offers new CPU options and an updated design compared to the G10 model. The latest version is powered by 28W Intel Meteor Lake-H CPUs which are more efficient than the Raptor Lake-H chips that can be found inside the previous-gen sibling. The dGPUs are expectedly pro-grade NVIDIA RTX Ada Generation chips with modest power limits for lower noise during heavy loads.

This device is meant for continuous workloads like AI tasks, 3D rendering, CAD, etc. That’s why HP has fitted a pretty sizable thermal system with quiet fans but more on that later. Display-wise, you get tons of choices including four 1200p screens (one of them has touch capabilities) and the most expensive model is a 120Hz 1600p unit. There is also a panel that offers the HP Sure View Reflect integrated privacy screen technology.

Since that’s a heavy-duty notebook, the upgradability and the port selection correspond to the high expectations. The machine is packed with useful features, many of which are optional, such as fingerprint reader and facial recognition.

What’s in the box?

We found some manuals and a 150W barrel plug adapter inside the package.


Design and construction

The design of the ZBook Power 16 G11 is slightly refreshed compared to the G10 version. The sides are more rounded, there is a lip on the main body for easier opening, the speakers are on the bottom, and the touchpad is placed a bit more on the right (and isn’t surrounded by a silver stripe). The all-aluminum chassis is sturdy, with a smooth finish resistant to smudges. While the lid could flex slightly, it’s not a major issue.

You can open this machine with one hand. The device isn’t a behemoth like the ZBook Fury 16 G10 but since it has a big cooling under the bonnet, it’s not among the thinnest workstations. The starting weight is 2.122 kg and the profile is 22.9 mm.

The bezels are thin, even the bottom one that houses the HP logo.

On the top, there is a normally-positioned 1080p Web camera with a privacy shutter and AI Noise Suppression tech. If you need facial recognition, you can opt for a 5MP IR unit.

When you open the laptop beyond a certain angle, the back of the lid lifts the rear of the chassis. This enhances the cooling capabilities of the notebook and the ergonomics during typing.

Here, the keyboard is a well-known spill-resistant unit with a Copilot shortcut that can be seen in many other devices from the same brand. It’s a comfortable board since the key travel and the feedback are on point. However, the small Arrows and the placement of the Page Up / Down keys on top of them are less than ideal for work. The optional fingerprint reader is positioned below the NumberPad. We still think that the keyboard of the EliteBook 860 G11 is an even better choice for long hours of typing.

The touchpad isn’t among the smoothest we’ve tested but its accuracy is great.

The bottom panel looks standard for such a laptop with its decently sized large ventilation grill, two long rubber feet, and a pair of cutouts for the speakers. The hot air is pushed through two vents on the back. Some amount of heat reaches the lower panel of the screen when the internals are heavily stressed.

Ports

On the left, there is a power connector, a pair of 40 Gbps Thunderbolt 4 / USB4 ports with USB Power Delivery and DisplayPort 2.1 functionality, an HDMI 2.1 for up to 4K@60Hz externals displays, a 5 Gbps USB Type-A 3.2 (Gen. 1) port that supports charging, an Audio combo jack, and a SmartCard reader (option). On the right, you get a Nano Security Lock Slot, LAN, one more 5 Gbps USB Type-A 3.2 (Gen. 1) port, an optional Nano SIM card slot, and an SD card reader 4.0 (option).

Color Coverage

The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.

Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of HP ZBook Power 16 G11 can show:

Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content

HP ZBook Power 16 G11: the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.

In our tests, we calculated the total color coverage of the monitor at 98% of the sRGB color gamut and 81% of the DCI-P3 color gamut.

(Fig.1) HP ZBook Power 16 G11 covers 98% of the sRGB gamut

Brightness and Contrast

The maximum brightness in SDR mode is 486 cd/m² in the center of the screen and 448 cd/m² averaged across the surface with a maximum deviation of 11%.

The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 5940K.

The contrast ratio is 1670:1.

Uniformity: Luminance, Contrast, and Color Deviation

The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 186 nits (Windows slider = 65%) — a brightness level we consider typical for standard working conditions.

DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.

Color Accuracy

Let’s check the difference between real colors and those you’ll see on the HP ZBook Power 16 G11. We measure that distance in DeltaE – the higher the number, the more different they look.

Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.

For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.

Before our calibration of the HP ZBook Power 16 G11, the Average color accuracy was 2.4 dE (Fig. 2), and with our Design and Gaming profile, it lowered to 0.9 dE (Fig. 3).

Visibility in dark scenes

Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.

The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Design and Gaming profile activated.

On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.

You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display 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 = 32.7 ms. Short pixel response time is a prerequisite for a smooth picture in dynamic scenes.

After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.

Health Impact: PWM (Screen flickering)

Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.

In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.

The light from the backlight of the HP ZBook Power 16 G11 display is not pulse-width modulated, providing visual comfort in the discussed aspect.

Health Impact: Blue light emissions

Installing our Health-Guard profile not only eliminates harmful PWM when the laptop uses it to control brightness but also reduces 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.

Health Impact: Screen Reflectance

Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.

The reflectance of the HP ZBook Power 16 G11’s screen is 56.8 GU.

High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

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.

It’s great to see that the RTX 2000 Ada Generation can sustain comparable core frequency and 15W lower power limit than the the ZBook Fury 16 G10 with the same dGPU.

Comfort during full load

The two fans produce a low amount of noise in “High Performance” mode.

During gaming, we measured 45°C on the keyboard’s hotspot and on the two zones of the bottom display bezel which are in front of the rear exhausts. The rest of the upper side of the chassis is cooler.

The “Smart Sense” preset offers  2.95 GHz / 2.50 GHz / 1.70 GHz and P,  E, and LP E-core clock in 100% CPU stress. The fans in this mode are nearly silent.

Battery

Now, we conduct the battery tests with the Windows’ Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with.  This laptop’s 83Wh battery pack lasts for around 17 hours of video playback. The result is great for such a powerful machine. Оur test was conducted with the “Battery Saver” preset activated in the Windows “Power & Battery” menu and the Smart Sence mode applied in the MyHP app.


Disassembly, Upgrade options, and Maintenance

To have a sneak peek at the internals of this workstation, you have to undo just 5 Phillips-head screws. The ones on the bottom aren’t captive while the others are. Pry the back behind the hinge cover with a thin plastic tool. When the clips are released, raise the plate close to the upper two edges to create gaps in these sections. Pop them and then pry the sides and the front.

Here’s how the bottom plate looks on the inside.

This workhorse is equipped with an 83Wh battery. To remove it, pull out the connector towards the battery and undo the 6 Phillips-head screws that hold the unit in place. The capacity is enough for around 17 hours of video playback. The result is great for such a powerful machine. Оur test was conducted with the “Battery Saver” preset activated in the Windows “Power & Battery” menu and the Smart Sence mode applied in the MyHP app.

Each SODIMM has a metal cap on top which can be popped with a lever tool. The preinstalled SSD is covered with a heat shield.

That’s the internal look of the laptop when the slots are fully revealed.

According to HP, the two SODIMMs fit up to 64GB of DDR5-5600 MHz RAM in dual-channel mode. However, since the CPU can support up to 96GB, this laptop likely wouldn’t have issues running a larger amount of memory than the official manufacturer’s specified limit. The RAM modules are also cooled by thermal pads below the plates and beneath the sticks.

In terms of storage, you can rely on two M.2 slots compatible with 2280 Gen 4 SSDs. A decently sized cooling pad is placed underneath the preinstalled NVMe drive.

Our laptop lacks a WWAN slot for optional 4G LTE connectivity, which should be positioned near the left fan. The Wi-Fi 6E card is on the right.

The cooling comprises a pair of fans, one long thick heat pipe shared between the CPU and the GPU plus one more pipe for each chip. The system is complemented by two heatsinks and two large heat spreaders.


Verdict

The ZBook Power 16 G11 is a solid metal workstation with potent cooling, quiet fans, and adequate performance. Also, the comfort during prolonged periods of max system stress is very good since the keyboard becomes just a bit warm on its top side. In terms of clocks, this is the best-performing machine with a Core Ultra 7 155H that we have tested up to date. The chip can sustain ~ 4.05 GHz / 2.69 GHz P and E core frequency in short loads and 3.24 GHz / 2.68 GHz in long heavy stress which is an outstanding result! The NVIDIA RTX 2000 Ada Generation is described as a 50W model, and yes, the chip can maintain this kind of power limit in graphics tasks.

The RAM modules are cooled by pads on both sides, which is a nice touch. This reminds us that the upgradability is good, thanks to the pair of SODIMMs and the two M.2 slots for 2280 Gen 4 SSDs. The port selection is also nice because of the duo of Thunderbolt 4 connectors.

The 1200p IPS display (CMN1636) is suitable even for content creation or other color-sensitive work. The PWM-free panel has 98% sRGB coverage, 486 nits of max brightness, and a 1670:1 contrast ratio. The color accuracy becomes great when our “Design and Gaming” profile is applied.

The HP ZBook Power 16 G11 amazes us with its very long battery life, superb thermal system, quiet operation, modern port selection, and color-accurate screen.
