Experience Seamless Performance: Introducing the HP EliteBook 840 G2
The EliteBook 840 G2 is styled in silver and gray, with a matte top surface that looks nice when it’s clean, but that readily shows fingerprints. Keep a wipe cloth handy if you care about such things. The chassis is magnesium and the keyboard is fabricated from aluminum, making the unit tougher than most and endowing it with a sturdy feel. HP says the laptop has passed a number of MIL-STD 810G tests, including drop, dust incursion, and vibration.
The display cover, which is protected by a surrounding rubber lip, continues the high-quality impression. The torsion-resistance is also on an excellent level, despite the thin construction. The hinges that connect the base unit and the display cover are very precise, but still smooth, so you can easily open the notebook with just one hand.

Apart from some details, there is no criticism concerning the build quality, either. The partly metallic surfaces, sometimes with a soft-touch coating, also provide very good haptics.
The HP EliteBook 840 G2 is a professional device and therefore offers a comprehensive port variety. A total of four USB 3.0 ports mean you can attach a lot of peripherals. External displays (up to two) can be attached via VGA and DisplayPort. You will, however, have to waive eSATA, the ExpressCard slot, as well as an optical drive – the price for the much smaller chassis construction compared to the predecessor. This is also the reason for the fold-out Gigabit-Ethernet port.
Communication

Intel provides the wireless adaptor Dual-Band Wireless-N 7260 that supports Bluetooth 4.0 as well as the WLAN standards 802.11a/b/g/n in 2.4 and 5 GHz networks, but not the latest and much faster 802.11ac. Depending on the router, the maximum transfer rate is therefore limited to 300 Mbps (2×2 dual-stream). Our practical test (o2 Box 4421, up to 150 Mbps) still showed that the EliteBook has a good signal quality and a stable connection over longer distances. The results obviously depend on the combination of notebook and router – an optionally offered WLAN module from Broadcom revealed more issues in the review of the EliteBook 850 G1.
We already know the webcam and the array microphone of the 840 G1 from its siblings. While the very clear and balanced voice recordings often make an additional headset redundant, we are not really convinced by the results of the 0.9 MP camera. Diffuse illumination only results in mediocre pictures with limited sharpness and washed-out colors. It is, however, sufficient for Skype or similar applications, but you should use a current smartphone for pictures.
Security
HP is very self-assured and advertises the EliteBook as equipped with solid security through several important features. The notebook has not only specially secured BIOS with support for Intel’s Anti-Theft technology, but also a TPM (TCG 1.2) encryption for the hard drive and a SmartCard reader. A handy fingerprint reader and a Kensington Lock against physical theft are obviously available as well. All the security features are handled by software tools like HP’s Client Security Suite.
Accessories
You can upgrade the preloaded Windows 7 Professional to Windows 8 Pro (each 64-bit) if you want to. The box contains the necessary DVDs – but you will have to use an external optical drive. Other accessories are limited to a compact 45-Watt power adaptor as well as some brochures.
Apart from several system tools like the HP Connection Manager or software for backups, the Windows installation looks pretty clean. Tools like Power DVD or YouCam can also be deleted very easily, which will increase the free capacity of the SSD (ex-works: 115 GB empty).
Touchpad and TrackPoint
The Synaptics touchpad is also very similar to the previously reviewed sibling. The size was reduced to 9.8 x 5.5 centimeters (~3.9 x 2.2 inches) due to the smaller case, but the excellent gliding capabilities and the good accuracy did not change. The two mouse buttons have a firm and well-defined pressure point and work reliably in the peripheral zones.

The HP Elitebook 840 G2 Display
Potential buyers of the 840 G1 can choose between four different 14-inch displays: The entry-level version with only 1366×768 pixels is only available in the cheaper configurations and is hardly suitable for a high-end product from the EliteBook-series in our opinion. One step above that is the WXGAA++ display of our review unit with 1600×900 pixels, which is also available with a touchscreen. The most expensive, but probably also the best panel is a high-resolution Full HD display.

In addition to the internal 50 Wh battery, you can also get another 60 Wh battery (HP C006XL) that can be attached at the bottom.
A more practical use results in a runtime between 5 and 6 hours. Considering the battery capacity, the result is typical for this notebook class and once again shows the advantages of the ULV system. A complete recharge takes around two and a half hours.
Graphics
The launch of the Haswell architecture was almost one year ago – and the formerly impressive performance of the integrated HD Graphics 4400 (GT2, 20 EUs) is now somewhat low-end. The comparatively high clock of 200 up to 1,100 MHz in the case of the i7-4600U does not really improve the situation, either, especially since the maximum Turbo Boost is barely utilized. The dual-channel memory configuration does at least improve the frame rates by around 15 – 40%. We would therefore recommend a second memory module for users of a 4 GB configuration with just one module.
While the performance of the HD 4400 is roughly on the level of the AMD Radeon HD 7570M in the EliteBook 8470p from last year, you can expect a significant performance improvement from the optional Radeon HD 8750M with GDDR5 memory. The GPU should be slightly faster than the GeForce GT 740M, which is roughly twice as fast as the Intel GPU.
The HD Graphics 4400 might not be the fastest GPU but is has some very useful features and is very frugal. Playback of a 4K trailer (H.264) with around 100 Mbps was smooth with a CPU load of less than 10%. Similarly impressive is the once again improved Quick Sync transcoder of Haswell that can accelerate video conversion by the factor 5 to 10.
The major difference between the HP EliteBook 840 G2 and it’s G1 predecessor is the processor. The HP EliteBook 840 G1 is powered by a 4th generation Intel Core i5 processor, while the HP EliteBook 840 G2 is powered by a 5th generation Intel Core i5 processor.
Other differences between the two laptops include:
- Display: The HP EliteBook 840 G2 has a slightly higher resolution display (1920×1080) than the HP EliteBook 840 G1 (1600×900).
- Storage: The HP EliteBook 840 G2 can be configured with a solid-state drive (SSD).
- Battery life: The HP EliteBook 840 G2 has a slightly longer battery life than the HP EliteBook 840 G1.
- Security features: The HP EliteBook 840 G2 has a number of additional security features, such as a fingerprint reader and a TPM chip.
Overall, the HP EliteBook 840 G2 is a more powerful and feature-rich laptop.
Which laptop is right for you?
If you are looking for a durable and reliable business laptop with a long battery life, the HP EliteBook 840 G2 is a good option to consider. However, if you need a more powerful laptop with additional security features, the HP EliteBook 840 G2 is a better choice.
