Dynabook Tecra A40-J review – performance in the office and on the go
Source: Laptop Media English EN→zh-CN
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.
