It is not always easy to find the perfect compromise between tradition and modernity – but HP did just that with the EliteBook 840 G1. The predecessor was a heavy and bulky working device, but the new version makes a huge jump forwards in terms of mobility. There are no impacts on the quality, either: The high build quality and stability did not change, and the same applies for the excellent input devices.
The lack of the optical drive and some older ports should only concern a few users, just like the slightly reduced processor performance. Only the replacement of the standard voltage CPUs enabled the manufacturer to combine a thin design with low emissions and long battery runtimes.
You will have to look very closely to find any serious drawbacks. One issue is certainly the TN panel with very limited viewing angles, but it can be replaced by an IPS display with Full HD resolution for an additional charge. The same applies for the integrated HD 4400 GPU: If the performance is not sufficient, you can just choose a configuration with the more powerful dedicated Radeon HD 8750M.
Overall, HP offers an attractive package that does not have to hide behind the rivals Lenovo ThinkPad T440s or Dell Latitude E7440. All three laptops have their own individual advantages – in the end you will have to decide for yourself.
