HP EliteBook 640 G11 review – Solid Performance and Portability
The EliteBook 640 G11 is the smaller version of the EliteBook 660 G11. Interestingly, the former device offers almost the same features and power as its bigger sibling. You can pick one with 15W or 28W Meteor Lake processors. The upgradability is decent while the port selection is great for a 14-incher thanks to the pair of Thunderbolt 4s.
In terms of display variants, you can choose from four IPS units with 1200p resolution. One of them is a touchscreen. Our device is equipped with the same panel, it’s not something spectacular but it’s good enough for standard office work.
Some of the most mouthwatering security features remain optional. We are talking about the Smart Card reader, the NFC, the fingerprint reader, and the IR Web camera. Still, all devices are tied with a privacy shutter, a dTPM 2.0 chip, and a Lock slot. Intel vPro Enterprise is available for all CPUs except the Core Ultra 5 125U.

What’s in the box?
Inside the box, you’ll find manuals and a 65W Type-C adapter.
Design and construction
The external look of the EliteBook 640 G11 is almost the same as that of the 660 G11 model. Overall, the metal chassis is solid. The lid rigidity is above average and the only place where you can slightly bend the base is the zone above the touchpad.
Unfortunately, you can’t open the machine with one hand. On the bright side, the portability seems good. The notebooks with the 48Wh battery weigh 1.39 kilos while the iterations with the optional 56Wh unit stop the scales at 1.40 kg. The 10.9 mm – 17.00 mm profile is also thin.
Except for the top bezel, the other three are thin.
The web camera with a privacy shutter is normally placed above the screen. You can choose between a 1080p unit and an optional 5MP IR variant for Windows Hello.
The hinge mechanism allows you to open the device up to around 177 degrees. This is still fine for content sharing. The lower side of the lid has two tiny rubber feet. When you push back the lid pretty far, it raises the back of the base. In this position, more fresh air reaches the cooling.
The spill-resistant keyboard has an AI hotkey and half-sized Arrows which aren’t exactly comfortable for work. Still, the board’s key travel and the feedback are on point. Unfortunately, the backlight isn’t a standard feature.
The touchpad size is good for a 14-icher. However, the pad’s smoothness and accuracy are average at best. Also, the clicking mechanism sounds loud on press.
Nothing unusual on the bottom plate – one ventilation girl, two speaker cutouts, and a pair of long rubber feet. The heat is guided via a vent on the rear. The hinge cover stands in front of it so not much hot air reaches the panel during heavy CPU loads.
Ports
On the left, you get an HDMI 2.1, a 5 Gbps USB Type-A 3.2 (Gen. 1) port with charging capabilities, a pair of 40 Gbps Thunderbolt 4 / USB4 ports that support USB Power Delivery and DisplayPort 2.1, an Audio combo jack, and an optional Smart Card reader. On the right side, there is a Lock slot, LAN, one more 5 Gbps USB Type-A 3.2 (Gen. 1) port, and a Nano SIM card slot (option).

Viewing angles are good. We take photos from different angles to evaluate the quality.
Also, a video with locked focus and exposure.
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 EliteBook 640 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 EliteBook 640 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 50% of the sRGB color gamut and 40% of the DCI-P3 color gamut.
(Fig.1) HP EliteBook 640 G11 covers 50% of the sRGB gamut
Brightness and Contrast
The maximum brightness in SDR mode is 315 cd/m² in the center of the screen and 303 cd/m² averaged across the surface with a maximum deviation of 10%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6180K.
The contrast ratio is 1300:1.
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 180 nits (Windows slider = 79%) — 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 EliteBook 640 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 EliteBook 640 G11, the Average color accuracy was 4.7 dE (Fig. 2), and with our Design and Office profile, it lowered to 4.3 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 HP EliteBook 640 G11 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 = 18.0 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 EliteBook 640 G11 display exhibits pulsations, but with high frequency and limited amplitude, which is why we believe it provides good visual comfort in this regard.
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 EliteBook 640 G11’s screen is 53.3 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

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.

The Core Ultra 7 155U sustains a pretty high P and E-core clock in short loads – 3.82 GHz / 3.12 GHz. The frequencies are reduced to around 2.70 GHz / 2.40 GHz in medium and long stress which is a great result for a laptop with a single-fan cooling.
Comfort during full load
When the processor is stressed at max in “Best Performance” mode, the fan noise is below average. In this scenario, the upper side of the keyboard feels just a bit warm. Yep, the comfort during max system stress is good.
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 56Wh battery pack lasts for around 10 hours and a half of video playback. Оur test was conducted with the “Battery Saver” preset activated in the Windows “Power & Battery” menu.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
Disassembly, Upgrade options, and Maintenance
To open this business machine, you have to undo just 5 captive Phillips-head screws. Pop the areas behind the hinge cover near the top two edges with a lever tool. Lift the middle as well. The next step is to pry the sides and the front.
Here’s how the bottom plate looks on the inside.
The device in front of us has the optional 56Wh battery. The default version is a 48Wh variant. To remove it, detach the connector by pulling it towards the unit and open the two latches on the bottom. Raise up the lower side of the unit by holding the two tabs and lift the battery away from the chassis. The capacity is enough for around 10 hours and a half of video playback.
The RAM section has a metal shield on top which can be popped with a lever tool.
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. There is a long thermal pad in front of each memory slot for additional cooling.
Sadly, you get just one 2280 Gen 4 M.2 slot for storage expansion. The replaceable Wi-Fi 6E card is on the right of the cooling.
The thermal system features one large fan, a long thick heat pipe, one heat sink, and a heat spreader.
Verdict
It’s nice to see that the HP EliteBook 640 G11 offers almost the same performance as its bigger 16-inch 660 G11 sibling. In short loads, the Core Ultra 7 155U maintains a 3.82 GHz / 3.12 GHz P and E-core frequency which is impressive given the cooling solution with one fan and a single heat pipe. In the long run, the result is ~ 2.70 GHz / 2.40 GHz. That’s more than enough for a snappy performance. Speaking of which, the SSD of our laptop (1TB KIOXIA KXG80ZNV1T02) is fast but it gets toasty if you torture it with long sustained write loads.
The 1200p touchscreen (AUOB9AC) has wide viewing angles and 315 nits of max brightness. Still, the sRGB coverage and the color accuracy don’t impress. HP states that some of the other optional panels for this series cover fully the sRGB gamut. Keep in mind that we can’t confirm that since we haven’t tested these screens but perhaps their colors should be more vibrant compared to the touch unit of our notebook.
The HP EliteBook 640 G11 offers adequate performance, a good port selection, a metal chassis, and a long battery life.
