Reviews for the Dynabook Tecra A40-J-12E

84.4% Dynabook Tecra A40 in review: A whisper in the office... | Notebookcheck
The extremely quiet laptop shows how much performance can be found in an 11th generation Intel i5 processor when it is installed accordingly. The laptop can score with its high battery life for a mid-range B2B device. Unfortunately, it falls short of expectations in other areas.

Dynabook Tecra A40-J review – performance in the office and on the go
Source: Laptop Media English
Surprisingly or not, Dynabook has built a really solid machine, especially when it comes to performance. And it has the cooling to back the processors up. In our opinion, they could have easily gone for the 35W Tiger Lake-H35 devices, or even AMD’s Zen 3 5000U processors. Unfortunately, the fingerprint reader is located inside the touchpad area. And the space above it and to its left is practically non-sensitive to touches, which is petty. However, what is even worse is the fact that the speakers here are no good. The mids are super muffled, while the lows are almost muted. Clearly, you won’t be satisfied, even if you’re not an audiophile. When it comes to the battery life, the laptop will last you about 10 hours of Web browsing, or 7 hours of video playback. This means it should last you a light workday on battery power, but if you throw anything heavier at it – bring a charger. At the end of the day, this business device brings a lot to the table. We think it has what it takes to battle the likes of the Dell Latitude 14 3420, or the Lenovo ThinkPad E14 Gen 2.

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.

The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.

» To find out how fine a display is, see our DPI List.

86.7%: This is an above-average rating. Nevertheless, it should not be forgotten that about one fifth of all tested models receive a better rating.
