HP EliteBook 840 G5 (i5-8250U, SSD, Full HD) Laptop Review

Sebastian Bade (translated by Katherine Bodner), 04/06/2018

A lot of changes! After HP only gave its business notebook a quick brush-up last year, a lot of changes have been made to the new EliteBook 840. There is the Kaby Lake Refresh processor and a new case redesign. This does not necessarily mean that new is always better. Find out what changes have been made and how the new business companion fares in our set of tests below.

The HP EliteBooks of the 800 series are premium business notebooks that position themselves just below top models such as the HP EliteBook Folio 1040 G4. Today, we will be taking a look at the fifth-generation of the HP EliteBook 840, which has been given a technical and optical overhaul and is quite different from its predecessor, the HP EliteBook 840 G4.  

Our test unit (model number 3JX66EA) is positioned in the center field compared to devices from other manufacturers. It is equipped with an up-to-date Intel Core i5-8250U with 8 GB of RAM, a 256-GB NVMe SSD and a Full HD IPS display. Our test configuration of the HP EliteBook 840 G5 is available for $1400 and also offers many security features, which business devices cannot go without nowadays.  

Alternatively, the device can also be equipped with a faster Intel Core i7-8650U, although this bumps the price up quite a bit. There is another, cheaper version of the HP EliteBook 840 G5 in the configuration with the Intel Core i5-7200U. However, this model offers significantly lower performance compared to eighth-generation chips. There are also different storage device and RAM configurations available. According to the technical specifications, the maximum is a 1-TB SSD and 32 GB of RAM.  

Will these changes suffice to beat the competition? The probably toughest competitor is the Lenovo ThinkPad T480s, which has a similar configuration. All comparison devices, including our test unit's predecessor, can be found in the table below.

Case - the HP EliteBook in a new look

The elegant silver aluminum case of the HP EliteBook 840 G5 looks very different to its predecessor (HP EliteBook 840 G4). The display cover has a contrasting edge at the top and the new HP logo emphasizes the elegant design. The new EliteBook 840 looks more angular, as the rounded corners at the back of the base have disappeared. The business notebook appears cleaner and of higher quality - both in look and feel. Its perfect workmanship is just as convincing as its stability - you need to apply strong pressure to warp the base unit. The display cover is easier to warp but is still acceptable. The pressure test shows that the case gives way slightly in the center of the base unit, but this is no reason for criticism. We would like to praise the display cover for not showing any waves on the screen under pressure.

Opening the device is quite easy and can be done with one hand. Despite the smooth hinges, the display hardly wobbles when typing. Optically, the HP EliteBook 840 G5 is very convincing and small features such as the webcam cover show that the manufacturer has also paid attention to functionality.

Size Comparison

Except for the Lenovo ThinkPad X1 Carbon, all comparison devices have very similar footprints. With a width of 32.6 cm (~12.8 in) and a depth of 23.4 cm (~9.1 in), the HP EliteBook 840 G5 does not take up too much space. The device is also relatively slim at 17.9 mm (~7.0 in) and does not appear bulky. The weight of our test unit is average for our comparison devices at about 1.5 kg (~3.3 lbs). The Acer TravelMate P648 is a bit heavier at 1.7 kg (~3.7 lbs). The power supply of the HP EliteBook 840 G5 adds another 334 grams (~11.7 oz) to the package. 

Connectivity - HP 840 G5 has USB Type-C but no card reader

The port selection of the HP EliteBook 840 G5 is good and bad at the same time. But let us start with the positive: Finally, the HP EliteBook 840 offers a USB Type-C port, which not only supports image output but can also supply the device with power. The ports are positioned on the sides of the device, although most of them have been placed on the right side. Aside from the already mentioned USB Type-C port, the device also has two conventional USB 3.1 ports (one on each side). The notebook also offers an HDMI port and an Ethernet connector. On the right side you will also find the proprietary docking station port, which enables you to easily connect to all devices at work. There is a Micro-SIM slot, but our test unit does not have a suitable WWAN module.

What we cannot understand is why HP has removed the SD card reader. Devices have sometimes been equipped with a microSD, but even this seems to have been deemed unnecessary here. Other well-known manufacturers have done it before, however - and it works. So the end user is left to fiddle around with adapters - USB ports are still available after all.

Communication

Wi-Fi module and a free WWAN slot
Wi-Fi module and a free WWAN slot

The wireless communication is taken care of by a 2x2 dual-band AC-Wi-Fi module from Intel, which also supports Bluetooth 4.2. During our measurements, which take place in ideal conditions, our test unit managed to attain very good results. We measured an average transfer rate of 523 Mbit/s when sending and 644 Mbit/s when receiving. HP has managed to improve the device's performance compared to its predecessor, and the fifth-generation EliteBook 840 also does well when confronted with its comparison devices. The Ethernet port offers an alternative network connection and can transmit data at up to 1 Gbit/s (sending and receiving). Both network connectors work reliably and we did not encounter any issues during our period of testing.

If you want to use the device to surf while on the go, you will have to add a suitable WWAN module. There is a free space for it next to the Wi-Fi module.

Security

HP Client Security
HP Client Security

Particularly business users rely strongly on their device's security features. Like its predecessor, the HP EliteBook 840 G5 offers a nice selection including a fingerprint reader, a SmartCard reader and the well-known slot for a security lock. Apart from the webcam, the EliteBook 840 G5 also has an infrared camera, which means it supports authentication via face recognition. After an easy setup, a quick look at the login screen will give you immediate access to your Windows account. HP has not only thought of hardware, however, and it has equipped our device with a variety of security programs including HP SureStart and HP Client Security, which enables you to manage all settings relevant to security.

Accessories

Apart from the device itself and its 65-watt power supply, the box only contains the obligatory safety and warranty information. If you would like additional accessories, you will have to purchase these separately. This includes the HP docking station with which you can easily connect the notebook to a good number of peripheral devices. The HP UltraSlim docking station costs another $135.

Maintenance

Maintenance work is relatively easy despite the missing maintenance hatch. Although you have to remove the entire bottom of the base unit, the HP EliteBook 840 G5 does not make this too difficult. We would still recommend using a plastic lever to avoid damaging the base unit. Once the bottom is removed, you can access all the important components. It is also easy to add a WWAN module, as all cables are already in place. Overall, the notebook is quite clearly constructed. Out test unit has a free slot for a second RAM module.

Warranty

Buyers will receive a 36-month limited warranty for parts and labor. You can also upgrade to a five-year on-site service (HP Care Pack).

Input Devices - comfortable keyboard and a good touchpad

Not only the HP EliteBook 840 G5 has been redesigned - its chiclet keyboard has also been given an overhaul. The keys have a nice size at 16 x 15 mm (~0.6 x 0.59 in) and their matte surface offers enough grip for fast typing. The keyboard still has crisp feedback, which is accompanied by good travel, and it remains protected from drops of water. Unlike Dell or Lenovo, the keys of the HP EliteBook 840 G5 are flat and do not have a conic shape. The arrow keys (up and down) are a little difficult to use and you are more likely to mistype due to their size.

Overall, we are pleased with the keyboard and the lettering is very easy to read. The device is also equipped with white backlighting that can be regulated in two levels. You can adjust the backlighting in the BIOS, by setting a timeout for the keyboard backlighting (5, 10, 30, 60 or 300 seconds). If you do not like timers, you can deactivate the feature. Backlighting can be turned on and off with a key combination. 

Touchpad/PointStick

The touchpad is higher and wider than its predecessor's was and now measures 11 x 6 cm (4.3 x 2.3 in) while the old version was 10 x 5.5 cm (~3.9 x 2.1 in). For this increase in size, HP had to get rid of the bottom mouse keys, which turns the touchpad into a ClickPad. The input area is smooth and the device reacted precisely to our inputs in all areas - even the corners. The two integrated mouse keys make a quiet clicking noise. The touchpad appears to be of high quality and fits nicely to the device's general impression.

Another feature of the HP EliteBook 840 G5, which the competition from Lenovo and Dell also features, is a point stick. With a little practice, this enables you to navigate quickly. The accompanying plastic keys above the ClickPad appear a little rickety, however. Compared to the overall concept, aluminum keys would have been a better choice.

Display - IPS for the EliteBook 840 G5

HP has made only IPS displays available for the HP EliteBook 840 G5, which offer a significant improvement compared to TN panels. If you look at the technical specifications, you can see that EliteBooks will also be available with a touch display. But it is not clear whether this option is limited to certain regions. The matte panel in our test unit comes from AU Optronics and offers a resolution of 1920x1080 pixels. This results in a pixel density of 157 PPI. During our measurements, the screen reached an average brightness of 387 cd/m², which places the HP EliteBook 840 G5 in second place behind the Lenovo ThinkPad X1 Carbon (533 cd/m²). But thanks to its low black value (0.25), the display still offers the best contrast ratio (1656:1).

The brightness distribution is not the best at 87%, but we did not notice any bothersome shadowing which would indicate irregular illumination. We did notice slight clouding in the top left corner, but this does not influence everyday office use. The EliteBook 840 G5 does not use PWM to regulate display brightness - good news.

The image quality is acceptable ex-works, but the EliteBook 840 G5 has a significant blue cast. The measured DeltaE 2000 deviation is also way too high. Calibration improves this and reduces the DeltaE 2000 deviation as well as the blue cast. You can find our ICC profile available for download above. The color-space coverage is decent at 88.1% of the sRGB and 56.9% of the AdobeRGB color space. The competition from Dell and Lenovo offers significantly better results. Compared to the HP EliteBook 840 G4, the fifth-generation shows visible improvements.

The matte display surface and the good brightness are great conditions for outdoor use. You can use the device outdoors when the sun is shining, although we would recommend finding a spot in the shade. Here, you can work freely as the matte surface prevents bothersome reflections. To be even better equipped for outdoor use, the manufacturer also offers special displays with up to 700 cd/m².

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
31.6 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 13.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.3 ms).
       Response Time 50% Grey to 80% Grey
42.4 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 22.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 56 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9937 (minimum: 43 - maximum: 588200) Hz was measured.

The viewing-angle test of the Full HD panel is very convincing and the test image can be seen very well from almost all angles. There are slight changes in color in the four corner images, but this will not lead to any limitations in everyday use.

Most users will do fine with the performance that our test configuration can offer. Although HP does have the fifth-generation EliteBook 840 G5 available with the older Intel Core i5-7200U as an entry-level version, we would suggest going for the Intel Core i5-8250U, which our unit is equipped with. The advantage in performance due to the double amount of cores is noticeable even in everyday use. Our 8 GB of RAM is also sufficient and can be expanded to up to 32 GB if necessary. The device has two RAM slots and neither is soldered on. Overall, the components in our test unit work together nicely, which the LatencyMon results confirm.

Processor

Intel Core i5-8250U
Intel Core i5-8250U

The processor is the well-known Intel Core i5-8250U, which is now used in many devices and is the successor of the Intel Core i5-7200U. It has a TDP of 15 watts and has four physical cores that can work up to eight threads simultaneously. The base clock rate is 1.6 GHz and can be overclocked to up to 3.4 GHz depending on the load. The HP EliteBook 840 G5 reaches similar results to the Lenovo ThinkPad T480s in the single-core benchmark but cannot quite keep up with it in our multithread test. This is due to the higher TDP limit. The HP EliteBook 840 G5 still has good results compared to the class average. It is interesting to see the results of the HP EliteBook 840 G4, as this is equipped with the Intel Core i5-7200U. Due to this difference in performance, we would not recommend buying the HP EliteBook 840 G5 equipped with the older i5 processor.

You can find further benchmarks for the Intel Core i5-8250U here.

The good cooling system means that the device can work quickly even under constant load. The HP EliteBook 840 G5 reaches 582 points in the first round of our Cinebench R15 Multi loop. Due to the perpetual thermal load, the results drop continuously over the next 10 rounds, until they settle down to around 505 points. This equates to a loss in performance of 13%, which is still acceptable.

Storage Devices

M.2 SSD from Toshiba
M.2 SSD from Toshiba
The Toshiba SSD with 256 GB of storage
The Toshiba SSD with 256 GB of storage

The storage device comes from Toshiba and offers 256 GB of space. Minus the system requirements, this leaves the user with about 174 GB available for free use. The M.2 SSD uses the fast NVMe protocol, which makes it speedier than regular SSDs that only use a SATA interface. However, our SSD could only convince us in its read rates during our test, although these do not fit to the manufacturer specifications from Toshiba (read: 2700 MB/s, write: 1050 MB/s). Its write rates were closer to SATA speeds. We assume that this is due to an issue with the drivers which can still be dealt with. A future BIOS update might also improve the SSD's performance a little.

But this does not mean that the performance is bad. You will not notice the "low" write rates in everyday use. We were pleased with the 4K read rate, which is around 30 MB/s. The boot times will benefit from this, as this is when many small files have to be loaded.

Graphics

The Intel UHD Graphics 620 takes care of the graphics department and can take a burden off the processor when displaying high-resolution videos thanks to its integrated hardware encoder. In the 3DMark comparison, the HP EliteBook 840 G5 can beat the Lenovo ThinkPad T480s once again. Performance can be increased even more by adding a second RAM module. However, the dual-channel mode cannot create miracles. If you require higher 3D performance, you should look for a device that is equipped with a dedicated graphics card - the HP EliteBook 840 G5 is also available with the discrete GPU AMD Radeon RX 540.

Gaming Performance

The low 3D performance of the Intel UHD Graphics 620 is not enough to display demanding games smoothly. If you are looking for a device that you can play games on, you might want to take a look at the version of the HP EliteBook 840 G5 that offers a dedicated graphics card.

The cooling unit of the HP EliteBook 840 G5

Without load, the HP EliteBook 840 G5 is completely silent and we did not hear the usual coil whine in our test unit, either. Only under load does the small cooling fan set to work and reach a maximum volume of 35.2 dB(A). This makes our test unit a little quieter than the Lenovo ThinkPad T480s. However, the devices from Fujitsu and Dell are even quieter than our test unit.

Temperature

3DMark 11 after stress test
3DMark 11 after stress test

The HP EliteBook 840 G5 has good case temperatures and only reaches 39.5 °C (~103.1 °F) under load. All other comparison devices become a lot hotter and often reach surface temperatures of 50 °C (~122 °F) and more. The temperatures are great on the inside, too. The processor reached a maximum of 83 °C (~181.4 °F) in our load test. The Intel Core i5-8250U also clocks at a good rate of 2.4 GHz, which is significantly higher than the base rate of 1.6 GHz. However, the processor cannot keep this up when the CPU and GPU are put under load at the same time, as both have to share the TDP of 15 watts. The CPU therefore only reaches an average clock rate of 1.4 GHz in the stress test (Prime95 and FurMark). The continuous load does not affect 3D performance negatively.

The two stereo speakers are positioned above the keyboard. This means that the sound output is not blocked or reflected by a table. Due to the device's small size, the membranes do not offer a lot of bass. Highs and mids take center stage and there is nothing the Bang & Olufsen software can do about it. Nonetheless, the integrated speakers are suitable for audio transmission and video-telephoning as speech output is clear and precise. Even at maximum volume we did not notice any distortions. For a better sound experience, we would still recommend using an external sound system that can be connected via the 3.5-mm audio jack.

Energy Management - the EliteBook is not an energy-saving wonder

Power Consumption

65-watt power supply
65-watt power supply
65-watt power supply
65-watt power supply

The HP EliteBook 840 G5 is not very energy-efficient. Although its consumption of 3.2 - 9.5 watts while idling is still OK, it climbs up to 65.5 watts for a short time under load. On average, the consumption settles down to around 36.2 watts. The included power supply offers a maximum of 65 watts and can supply sufficient power as the maximum consumption rate drops after about 10 seconds. The Lenovo ThinkPad T480s cannot offer better rates, however. It actually consumes about 8% more energy with a similar configuration.

The battery runtimes are not as good as the HP EliteBook 840 G5's competition. The 50-Wh battery is not removable and can sustain the business device for about 7.5 hours during our Wi-Fi test. This is tight if you are hoping to manage a whole workday without having to recharge. The fast charging times offer a little consolation: It only takes just over 2 hours to fully recharge. We noticed that 3D performance is not as good on battery, but this is not very important.

The HP EliteBook 840 G5 is a high-quality business device, now in its fifth generation. The successor of the HP EliteBook 840 G4 has been given a new design and an up-to-date Kaby Lake Refresh processor, although this cannot reach its full potential. Buyers should also be aware of which configuration they purchase, as the HP EliteBook 840 G5 is also available with seventh-generation Intel processors.

Our test unit is equipped with an Intel Core i5-8250U, 8 GB of RAM and a 256-GB SSD, and the device provides very good system performance. HP has also decided to only offer IPS panels in this version, which has significant advantages. At a price of $1400, the device offers perfect workmanship, good performance and many security features, which are a must for any business laptop.

The new HP EliteBook 840 G5 is impressive with its fancy design and perfect workmanship. The good input devices are just as important as the many security features the EliteBook 840 G5 has to offer.

The HP EliteBook 840 G5 loses several points in the areas of power consumption and battery runtime. Its competition proves that it could do better. But if you do not have to deal with long stretches of time without access to sockets, you will be very pleased with the HP EliteBook 840 G5. We were a lot more bothered by the missing SD card reader, which does not make any sense. Luckily, the business companion does offer a USB Type-C port that supports Thunderbolt.
