HP EliteBook 840 G6 is part of the latest generation of EliteBook 800 laptops. Traditionally, the EliteBook brand has been known for its extreme reliability and longevity in terms of degradation and moral ageing.

Interestingly, this laptop doesn’t differ a lot from its predecessor from the fifth generation 800 devices. While it retains the aluminium chassis, it now embodies the Whiskey Lake processors from Intel.

Design and Construction

This device’s design was designed from both the Ultrabook and the industrial family of laptops. its body is built entirely out of aluminium.







The EliteBook is 17.9mm in thickness and weighs 1.48 kg. It is very easy to handle around.

Right above the display, two circular cut-outs are hiding the IR sensors for face recognition. However, this is not the only biometric sensor on this laptop.

The other one is located on the bottom right corner of the base and it is the fingerprint reader. Above it, there is a spill-resistant keyboard that has a nice key trip and decent tactile feedback. Moreover, it is backlit and features a nipple, just above the “B” key. Its buttons are placed above the glass-fitted touchpad, which itself feels fast and accurate.

Then, at the bottom plate, there is only one, though a rather big grill, which is clearly meant for ventilation. While the hot air escapes from the left side, the speakers are nowhere to be found on the bottom. This is because, they have their place at the base, just above the keyboard. Plus, they have Bang & Olufsen branding, which means they are tuned from the Audio company.



On the left, there is a USB Type-A 3.1 (Gen. 1) port with a charging function, as well as the optional Smart Card reader. Looking on the right, there is a charging plug and a Thunderbolt port, either of which can be used for charging (depending on the charger, of course). Then, there is a docking connector, as well as an RJ-45 and HDMI connectors, followed by another USB Type-A 3.1 (Gen. 1) port, an audio jack, and an optional SIM card tray.

Display Quality

HP EliteBook 840 G6 has a Full HD IPS display. Its diagonal is 14″ (35.56 cm), and the resolution is 1920 х 1080. Additionally, the screen ratio is 16:9, the pixel density is 157 PPI, their pitch is 0.161 x 0.161 mm. The screen can be considered Retina when viewed from at least 56 cm. It has excellent viewing angles.

The maximum measured brightness is 444 nits (cd/m2) in the middle of the screen and 417 nits (cd/m2) average across the surface with a maximum deviation of 12%.

PWM (Screen Flickering)

Pulse-width modulation (PWM) is an easy way to control monitor brightness. When the brightness is lowered, 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 the eyes.

HP EliteBook 840 G6’s display backlight uses PWM to adjust the level of its brightness up until 118 nits. Additionally, the frequency of the flickers is high enough, so that it doesn’t hurt the eyes in this aspect.


The laptop is loaded with a quad-core Intel Core i7-8565U processor, 32GB RAM memory size, a storage capacity of 512 GB SSD and an Intel UHD Graphics 620, which allows the notebook to perform multitasking with ease. Its operating system is Windows 10 Pro 64.

Battery Life

The battery capacity is a modest one at 50Wh. The battery life is good, around 16 hours of web browsing and over 12 hours of watching HD videos.

Power, security, productivity and entertainment, the EliteBook 840 excels at it all. From its keyboard and privacy display to its speakers and performance, every aspect of this business laptop is high quality.
