At first glance, the EliteBook 840 G1 shares many similarities with its siblings, the 820 G1 and 850 G1. No wonder: Curved shapes and a black-silver color scheme are basic design elements of the whole series from now on, so the individual models differ mostly in size and weight. We measure a weight of 1.78 kilograms (~3.9 pounds) for the 14-inch laptop, which is just average within the competition. Still, the 2.1 cm (~0.8 in) thick 840 G1 can use the desired Ultrabook title and offers good mobility.

However, not only was the mobility important during the development; the case, which is made of aluminum and magnesium, also had to prove its durability during military tests according to MIL-STD 810G. HP-™s claim sounds realistic, since the base unit is extremely sturdy and handles concentrated pressure without problems. 

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 competition is not superior.
