A Lenovo continua sua linha Yoga de gama alta com o Yoga C940-14IIL e a equipou com os mais recentes processadores Ice Lake pela primeira vez. Esta é uma atualização evolutiva bem executada.
Sem dúvida, o novo Intel Core i7 2617M é o coração da tablet Yoga. Em termos de CPU e especialmente de desempenho da GPU, as novas plataformas de CPU trazem uma enorme melhoria no desempenho, o que torna o Yoga C940 adequado inclusive para jogos leves. Isso foi feito sem aumento de calor ou ruído - pelo contrário, há uma diminuição nas duas áreas. A duração da bateria continua sendo boa. Em comparação com o Yoga C930, existe uma tela FHD nova e mais brilhante, que é definitivamente uma melhoria bem-vinda. Além disso, a Lenovo carrega muitas coisas boas dos antecessores, como a construção de metal premium, a caneta integrada ou o forte sistema de alto-falantes quádruplos.
Quase não existem pontos fracos. Um dos poucos é definitivamente a falta de portas, bem como p pouco de ruído de bobina. Além disso, é desnecessariamente complicado abrir o Yoga C940 (pois os parafusos estão escondidos sob os pés de borracha). Seria bom também se a Lenovo oferecesse uma opção de tela mate e se o painel LCD atingisse o valor de brilho prometido de 400 cd/m².
A Lenovo não comete nenhum erro neste caso - e é por isso que o Lenovo Yoga C940-14IIL provavelmente entrará em muitas listas de desejos nesta temporada de férias.
Esses pontos fracos não são decisivos para nós. Podemos recomendar sinceramente o Lenovo Yoga C940-14IIL. É um portátil premium que oferece muita qualidade e flexibilidade, que os grupos-alvo, como os alunos, apreciarão. O Dell XPS 13 7390 2-in-1 tem um concorrente difícil aqui.
