Breve Análise do Portátil Acer TravelMate P257-M-56AX

Name: Acer TravelMate P257-M-56AX
Brand: Acer

Controle térmico perfeito. Sem importar o que fizermos com o recém-chegado da Acer, o núcleo nunca reduziu sua velocidade do máximo especificado - inclusive no modo de bateria. Dignamente, o TravelMate foi quase perfeito em termos de temperatura e ruídos. Será que a tela e os dispositivos de entrada conseguem manter o nível?

In review: Acer TravelMate P257-M-56AX. Test model courtesy of cyberport.de

De fato, somente o preço do Acer TravelMate P257-M-56AX teria que cair um pouco para garantir uma recomendação de compra. Em nossa opinião, 720 Euros (~$792) são aceitáveis e sem dúvida baixarão nos próximos meses.

Em nossa análise, encaramos um aparelho de escritório bastante sólido. Seu único ponto fraco é a tela medíocre.

Além do controle térmico prefeito, o modelo de teste brilha com um visual ambicioso, carcaça sólida e bem construída, dispositivos de entrada muito bons, operação silenciosa e fria, suficiente duração da bateria, e poder mais que suficiente. Os usuários que desejam jogar alguns jogos exigentes podem optar, por exemplo, pelo Lenovo Z51-70 ou um modelo P2 (mais caro) com uma GeForce 940M.
