Reviews for the Dynabook Portégé X30L-K-139

85.1% Dynabook Portégé X30L-K-139 review - Business laptop weighs only 900 grams | Notebookcheck
Dynabook has equipped the Portégé X30L with Intel’s current Alder Lake processor. The magnesium case is extremely light at around 900 grams, which makes the business notebook an extremely mobile companion. However, the performance of the new processor falls short of expectations.
90% Dynabook Portégé X30L-K laptop review
Source: Techradar English
While most of us in this office work from laptops, some Apple, some HP, some Lenovo etc., we were astonished at just how much easier this Dynabook was to carry around. We’d pop over to a coffee shop and feel like we weren’t even bringing anything with us, it was so light. Yet, all that weight was gone without a significant drop in power. We’d recommend considering this laptop if you often work on the go, or if you are looking for something to easily carry around as a top-end portable working machine.
