Fujitsu Lifebook U939: An ultra-light business laptop
With the Lifebook U939, Fujitsu offers an extremely light business notebook. Even though its weight is less than 1 kilogram (<2.2 lb), this has no negative effect on the available connection equipment. With a smart card reader, GigabitLAN, two Thunderbolt 3 ports, and more, the basic needs of most users are more than fulfilled, and you get many expansion options by using adapters or docking stations.
We can attest the 13.3-inch display with very solid values in our test that are hardly any worse than those of the competitors. Another positive characteristic lies in the fact that the bottom of the case can be opened easily. However, at that point you can see that Fujitsu had to make some sacrifices to get the low weight. We would have also liked it, if the keyboard had been improved.
Hardly any maintenance options
The Lifebook U939 is currently available in two working memory configurations. However, whether you decide for the 8 GB or the 16 GB option, the RAM is always soldered in tightly in a dual-channel configuration. But since you can replace the SSD, the WLAN, and the LTE module inside, we ask ourselves whether this would have been really necessary to save weight. Considering that the rest of the equipment is good otherwise, we would have liked more freedom here.
On the other hand, we are watching the increasing discussions, whether the end user still needs to be able to replace or expand the working memory at all. Those who directly choose the 16 GB configuration should not suffer any lack of RAM in the long run. Our review of the Fujitsu Lifebook U939 will reveal the additional weaknesses and also the strengths of the compact business laptop.
