At first glance, the HP EliteBook 845 G10 may look like a slightly different version of the EliteBook 640 G10, but the former is a more premium device that is based on the latest and greatest AMD Zen 4 CPUs. No matter the compact dimensions, the top processor option is the mighty Ryzen 9 PRO 7940HS. You can choose among seven CPU options including Zen 4 non-PRO and PRO chips (Phoenix-U / Phoenix-HS). No dGPUs here but the new-gen iGPUs are pretty snappy, especially the Radeon 780M. Display-wise, you can find this machine with four different 16:10 IPS panels. Three of them are 1200p units (including one touchscreen) and the most expensive variant is a 1600p model. We can hint that the upgradability is decent, and the I/O is up to date with its two Thunderbolt 4 ports. All devices rely on Wi-Fi 6E + Bluetooth 5.3 for connectivity. If your wallet is wide enough, you can opt for extras like an IR Web camera, fingerprint reader, Smartcard reader, bigger battery, LTE or 5G eSIM functionality, and a backlit keyboard. Still, things like NFC, Bang & Olufsen speakers, self-healing bios, and a TPM 2.0 chip are standard features. You can check the prices and configurations in our Specs System: https://laptopmedia.com/series/hp-elitebook-845-g10/ Specs, Drivers, What's in the box Drivers All drivers and utilities for this notebook can be found here: https://support.hp.com/us-en/drivers/hp-elitebook-845-14-inch-g10-notebook-pc/2101628462 What's in the box? Inside the package, you'll find the mandatory paperwork and a 65W USB Type-C power adapter. Design and construction The all-metal chassis looks modern and stealthy which is important for a business machine. The laptop is light - the starting weight is 1.38 kilos. The profile thickness of 19.22 mm is okay for a notebook that can be configured with a 35W CPU. By the way, the matte finish doesn't attract a lot of fingerprints. Now, the lid can't be opened with a single hand and it's averagely flexible which is a bit strange for a device of this caliber. The base can be slightly bent in the middle of the zone above the keyboard. The area between the Space key and the touchpad alongside the top section of the right palm rest area can be pressed down a bit. All in all, the base rigidity is okay since we didn't spot any spongyness during typing. The black-colored narrow bezels around the panel contrast very well with the silver chassis. According to HP, this laptop can be found without a Web camera. Aside from that, you can pick one with a 5MP USB2 or 5MP USB2 infrared model. The top option is a 5MP IR variant with a privacy shutter. The lid lifts the back of the notebook but that happens at a very wide angle of opening which isn't optimal for work. Still, when the base is raised, this allows more fresh air to reach the internals. The fingerprint reader (option) is positioned below the Arrows keys which are half-sized. The spill-resistant keyboard is suitable for long typing sessions because of the long key travel and the clicky feedback. Sadly, the backlight is another optional feature. The touchpad houses an NFC sensor. The pad has a smooth glass surface that allows effortless gliding. The accuracy is also very good. If you flip the notebook upside down, you'll see two long rubber feet, two speaker cutouts, and a small ventilation grill. The hot air is pushed through a vent on the back side of the machine. When the CPU is heavily loaded, a bit of heat makes its way to the panel. Ports On the left, you can see an HDMI 2.1, a USB Type-A 3.2 (Gen. 1) port, two Thunderbolt 4 / USB4 40Gbps connectors (both support USB Power Delivery and DisplayPort 1.4), and a Smartcard Reader (option). On the right, you get an Audio combo jack, a USB Type-A 3.2 (Gen. 1) port with charging capabilities, a Nano Security Lock slot, and a SIM Card Slot for optional LTE or 5G connectivity. Display quality, Health impact (PWM), Sound HP EliteBook 845 G10 is equipped with a WUXGA panel, model number Innolux CMN1433. It comes with a 60Hz refresh rate. Its diagonal is 14.0" (35.6 cm), and the resolution - 1920 x 1200p. Additionally, the screen ratio is 16:10, the pixel density – 162 ppi, and their pitch – 0.16 x 0.16 mm. The screen can be considered Retina when viewed from at least 53 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 250 nits (cd/m2) in the middle of the screen and 231 nits (cd/m2) average across the surface with a maximum deviation of 18% (above what is acceptable). The Correlated Color Temperature on a white screen and at maximum brightness is 6140K (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 72% Brightness (White level = 140 cd/m2, Black level = 0.08 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 very good – 1680:1. 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 845 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 845 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 = 22.6 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 845 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 51.9 GU). Sound HP EliteBook 845 G10's "Bang & Olufsen" speakers produce a sound of very good quality. Its low, mid, and high tones are clear of deviations.

Performance: CPU, GPU, Gaming Tests All benchmarks and tests were conducted with the "Best performance" preset activated in the Windows “Power & Battery” menu. Also, the "Fan always on while on AC Power" function is enabled in the BIOS. There, the "Video memory size" is set to "Gaming optimized" - this allows the iGPU to use up to 2GB of system memory when needed. CPU options You can find this notebook with the AMD Ryzen 5 7540U, Ryzen 7 7840U, Ryzen 5 PRO 7540U, Ryzen 7 PRO 7840U, Ryzen 7 PRO 7840HS, or Ryzen 9 PRO 7940HS. GPU options Depending on which CPU is fitted under the hood, the iGPU can be the AMD Radeon 740M or Radeon 780M. Gaming tests CS:GO HD 1080p, Low (Check settings) HD 1080p, Medium (Check settings) HD 1080p, MAX (Check settings) Average FPS 120 fps - - DOTA 2 HD 1080p, Low (Check settings) HD 1080p, Normal (Check settings) HD 1080p, High (Check settings) Average FPS 121 fps 76 fps 49 fps Interestingly, the MSAA option in CS:GO is unavailable and that's why we didn't test the game on Medium and MAX settings. Aside from that, the AMD Radeon 780M performs well. Our configuration has one stick of 16GB RAM that works in single-channel mode. The CPU and the integrated video card could be snappier if the memory is working in dual-channel mode. [eBook Guide + Tools] How to MAX OUT your Laptop Temperatures and comfort, Battery Life 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. Average core frequency (base frequency + X); CPU temp. AMD Ryzen 7 PRO 7840U (15W TDP) 0:02 - 0:10 sec 0:15 - 0:30 sec 10:00 - 15:00 min HP EliteBook 845 G10 3.76 GHz @ 46°C @ 29.2W 3.41 GHz @ 54°C @ 25W 3.18 GHz @ 72°C @ 25W The base clock of the Ryzen 7 PRO 7840U is 3.30 GHz. Here, the CPU can sustain ~3.20 GHz in long periods of 100% load so we can call it a day. In this case, the power limit is 25W and the chip temperature is 72°C. This reminds us that the processor thermals are super low in short and medium stress which is great. Comfort during full load Since there are no presets in the HP Power Manager software, you have to use the default Windows modes to control the performance. The CPU is near-silent even when the CPU is doing the heavy lifting for a long time. In this case, the keyboard feels a bit warm in the middle so you can use the laptop comfortably for typing. The fan will not spin in idle if you uncheck the "Fan always on while on AC Power" function in the BIOS. 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. It lasts for 12 hours and 30 minutes of either Web browsing or video playback. The result is very good! 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” section. Disassembly, Upgrade options, and Maintenance If you want to open this device, you have to undo only 5 captive Phillips-head screws. Then, raise the bottom panel in one of the two zones that are near the top corners to create a small gap between the base and the plate. With that out of the way, you can pry the panel with a thin plastic tool starting from the back. There is a small thermal pad on the inside of the bottom plate for cooling the WLAN card. In our case, HP forgot to peel the protective tape and the pad isn't making direct contact with the Wi-Fi module. This notebook has the optional 51.3Wh battery. The base version is a 38Wh variant. If you have to remove the battery, pull out the connector from the motherboard, and undo the four Phillips-head screws that fix the model to the base. The optional capacity is enough for 12 hours and 30 minutes of either Web browsing or video playback. Memory-wise, there are two SODIMMs for up to 64GB of DDR5-5600MHz RAM in dual-channel mode. The RAM section is protected by a metal shroud. For storage, you get just one M.2 slot compatible with 2280 Gen 4 SSDs. The preinstalled NVMe has a thermal pad on the top that makes contact with the metal bottom plate for better cooling. We can spot another pad below the SSD. The WWAN slot is for optional LTE or 5G connectivity. The cooling system has one sizable fan, a heat pipe, one heat sink, and a heat spreader. Storage performance The SSD of our machine is the 512GB SAMSUNG MZVL4512HBLU-00BH1. It reached 56°C during the testing. Below you can see some benchmarks of this SSD. Verdict The HP EliteBook 845 G10 is an office device with a metal build and you can find this machine with powerful Zen 4 CPUs under the hood. In our case, the Ryzen 7 PRO 7840U is well-cooled. The chip temperature in short and medium loads is 46°C / 54°C which is a great result. In the long run, the chip can maintain a 25W power limit alongside a 3.2GHz clock. Even then, the fan is near-silent and the keyboard becomes a bit warm but not too hot. The comfort under maximum CPU stress is surprisingly good. The keyboard has a long key travel and a clicky feedback so you can use it for long hours of typing. The touchpad is big, accurate, and has a smooth glass surface. The I/O includes two Thunderbolt 4 ports, two Type-A connectors, and an HDMI 2.1 - all looks fine here. Since the device has a WWAN slot, you can order it with an optional LTE or 5G support. Speaking of slots, the two SODIMMs fit up to 64GB of fast DDR5-5600 RAM in dual-channel mode. This makes the laptop a future-proof machine. However, there is just one M.2 slot for 2280 Gen 4 NVMes. At least you can replace the SSD with a bigger one when you need more storage. Our notebook feels very responsive under any kind of load no matter the fact that the memory works in single-channel mode. Yes, if you want your device to be as snappy as possible, dual-channel memory is a must. The battery life is very long - more than 12 hours of Web browsing. The display quality is fine for an office machine. The sRGB coverage and the color accuracy don't impress but the 1200p IPS panel (Innolux CMN1433) is PWM-free and has comfortable viewing angles. The HP EliteBook 845 G10 is a good office machine that has a metal build, long battery life, a PWM-free display, long battery life, good comfort under load, and a modern I/O.
