The EliteBook lineup is constantly growing and it offers business devices in many different price ranges. The HP EliteBook 640 G10 is a small 14-inch laptop that has a good amount of security features such as a TMP 2.0 chip, a self-healing BIOS, a Web camera with a privacy shutter, HP Tamper Lock (that will warn you if someone has opened the laptop and modified / changed the hardware), etc. If you work in a crowded office environment and don't want someone to have a sneak peek at the personal info on screen, you can get a display with HP Sure View tech (the panel becomes tinted for people viewing it from the left or the right). If you want your laptop to be full of useful extras such as an IR camera, fingerprint reader, LTE connectivity, a Smartcard Reader, or a vPro CPU you have to pay more for these optional goodies. Speaking of which, seven different Intel 13th Gen CPU variants are available. This includes two P-series 28W processors for those who need extra power. The other offerings are 15W U chips that are more efficient. Display-wise, you can choose among many 1080p units and there is even a touchscreen model. We spot a 768p TN panel in the specs - avoid it like the plague. We can hint that the I/O is good and you get Wi-Fi 6E + Bluetooth 5.3 for connectivity. You can check the prices and configurations in our Specs System: https://laptopmedia.com/series/hp-elitebook-640-g10/ Specs, Drivers, What's in the box Drivers All drivers and utilities for this notebook can be found here: https://support.hp.com/in-en/drivers/hp-elitebook-640-14-inch-g10-notebook-pc/2101595033 What's in the box? Inside the box, you can find some paperwork and a 65W USB Type-C or barrel-style power adapter. Design and construction It looks like HP doesn't like to experiment with the design because the device in front of us looks almost the same as the EliteBook 640 G9. Aside from that, only the bezels around the display and the stripe on the top of the lid are plastic, the rest of the chassis is made of metal. The finish isn't a fingerprint magnet. The weight is low - 1.41 kilos while the 19.9 mm profile isn't among the thinnest for a 14-incher. On the bright side, this positively affects the cooling because there is more room available for the thermal system. The hinge stiffness is well-tuned - the lid can be opened with a single hand and that happens smoothly. However, the unit can be bent in the middle with ease and it's also flexible and bouncy. The base rigidness is okay, the keyboard deck doesn't flex during typing. We observe a bit of sponginess in the zone between the Space key and touchpad and the grill on the top of the keyboard can be pressed down in the middle. Overall, nothing too serious. The plastic bezels around the display are thin, especially the side ones. The Web camera with a privacy shutter and Temporal Noise Reduction is placed above the panel. The base one is a 720p model. An IR variant with the same resolution is also available as well as a 5MP IR iteration. The laptop can be opened up to 177 degrees. The lid also acts as a lever and it lifts the backside of the device but unfortunately, that happens at a very wide angle of opening which isn't very comfortable for normal work. There are no rubber feet on the bottom of the lid so sooner or later the surface in the zone will be scratched. The optional fingerprint reader can be found in the right palm rest area. The two 2W font-firing speakers are positioned above the keyboard. The latter is very comfortable for typing because of the long key travel and the clicky feedback. The generous free space around every keycap can be appreciated by everyone. The board is spill-resistant but the backlight is an option. The decently sized touchpad has an NFC sensor on its top right side. The smoothness of the surface and the accuracy are average. Two long rubber feet and a ventilation grill are part of the bottom plate. The heat is guided through a vent on the back of the device. Under heavy CPU stress, some amount of hot air reaches the display. Ports On the left, there is a Nano Security Lock Slot, LAN, a USB Type-A 3.2 (Gen. 1) port with charging capabilities, and a Smart Card reader (option). On the right, you can see a power plug, a Thunderbolt 4 connector, a USB Type-C 3.2 (Gen. 2) port, another USB Type-A 3.2 (Gen. 1) port, an HDMI 2.1 connector, an Audio combo jack, and an optional SIM card slot. Both Type-Cs support USB Power Delivery and DisplayPort 1.4. Display quality, Health impact (PWM), Sound HP EliteBook 640 G10 is equipped with a Full HD IPS panel, model number LG Display LGD0724. It comes with a 60Hz refresh rate. Its diagonal is 14.0" (35.5 cm), and the resolution - 1920 x 1080p. Additionally, the screen ratio is 16:9, the pixel density – 157 ppi, and their pitch – 0.16 x 0.16 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). Viewing angles are comfortable. We offer images at different angles to evaluate the quality. Also, a video with locked focus and exposure. The maximum measured brightness is 276 nits (cd/m2) in the middle of the screen and 259 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 6780K (average). In the illustration below you can see how the display performs from a uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 74% Brightness (White level = 141 cd/m2, Black level = 0.13 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 good – 1100:1. 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 on 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 EliteBook 640 G10's color gamut coverage. Its display covers 53% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976 and 41% of DCI-P3. 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 the HP EliteBook 640 G10 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 = 23.9 ms. 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) 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 640 G10's display doesn't flicker at any brightness level. This makes the screen pretty comfortable for long periods of use. Health Impact: 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. Health Impact: Gloss-level measurement Glossy-coated displays are sometimes inconvenient in high ambient light conditions. We show the level of reflection on the screen for the respective laptop when the display is turned off and the measurement angle is 60° (in this case, the result is 24.1 GU). Sound HP EliteBook 640 G10's speakers produce a sound of relatively good quality. However, the low, mid, and high tones all have some slight deviations from clarity.

The frequencies in prolonged periods of 100% processor stress are also very good, especially for a 14-inch device. Comfort during full load There are no dedicated power presets in the HP Power Manager app. This means you have to use the default Windows performance modes. Under serious CPU stress, the keyboard isn't too hot to the touch and the fan is quiet. The laptop can be dead silent in idle or light usage if you deselect the "Fan always on while on AC Power" function in the BIOS. In short, this HP machine offers very good comfort under any kind of system stress. 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 configuration is equipped with a 51.3Wh battery pack. It lasts for 12 hours and 30 minutes of Web browsing or 9 hours and 5 minutes of video playback. To achieve that, you have to select the "HP Optimized (Modern Standby)" power plan that can be found in the Control Panel's Power Options sub-menu. Also, you have to apply the “Balanced” preset in the Windows “Power & Battery” menu. Make sure that the "Max DC Performance" option is turned off in the BIOS. If not, this will harm the battery life because the Turbo Boost Technology will be turned on even when the power adapter is not connected. Disassembly, Upgrade options, and Maintenance To gain access to the internals, you need to undo just 5 captive Phillips-head screws. Then, lift the bottom panel close to one of the top corners to create a slight gap between the chassis and the metal piece. After that, pry the corner with a thin plastic tool. The rest is easy - just work your way around all sides of the device. Here's how the bottom plate looks on the inside. The battery is a 51.3Wh model. To take it out, detach the connector from the mainboard, and undo four Phillips-head screws that keep the unit in place. The capacity is enough for for 12 hours and 30 minutes of Web browsing or 9 hours and 5 minutes of video playback. For memory upgrades, you get two SODIMMs for up to 64GB of DDR4-3200MHz RAM in dual-channel mode. Storage-wise, there are two M.2 slots. The one on the left side of the battery fits 2230 SSDs or a WWAN card for optional LTE connectivity. The second slot is compatible with 2280 Gen 4 NVMes. The thermal system comprises one large fan, a heat pipe, one top-mounted heat sink, and a heat spreader. Storage performance The SSD of our notebook is the 512GB SOLIDIGM SSDPFKNU512GZH which is a QLC Gen 4 NVMe. Its temperature during our testing reached 53°C. Below you can see some benchmarks of this SSD. Verdict The HP EliteBook 640 G10 is a business device that can attract future buyers with its good comfort under load and capable cooling solution that allows high CPU frequencies even during max processor stress. The keyboard is also suitable for countless hours of typing because of the long key travel and the clicky feedback. The metal chassis feels premium to the touch but its overall solidness isn't the best we've seen. The 16:9 1080p IPS display (LG Display LGD0724) is all you need for normal work. It offers wide viewing angles and there is no sign of PWM usage so you can use the laptop for prolonged periods of work without sensing eye strain (you have to take regular breaks from time to time). However, the panel color coverage and maximum brightness are unimpressive. The upgradability is surprisingly good for a 14-incher - two DDR4 SODIMMs for up to 64GB RAM and two M.2 slots. The I/O seems modern with its four USB ports, HDMI 2.1, and an Ethernet connector. The thing that we don't like is the fact that many extras are optional and even the keyboard backlight falls into this category. The battery has a modest capacity of just 51.3Wh but that's enough for more than 12 hours of Web browsing on a single charge. Keep in mind that our laptop has a 15W U-series CPU under the hood, if you pick a device with a more thirsty 28W P chip, the autonomous life could be shorter. The HP EliteBook 640 G10 has a capable and quiet cooling solution, good upgradability, and long battery life.
