Inclusive se o HP EliteBook 820 G4 é, mais que nada, uma atualização Kaby Lake, poderia ser interessante para os proprietários do predecessor. No entanto, isto não se deve ao baixo ganho de desempenho do Kaby Lake em comparação com Skylake.
Durações de bateria bastante mais longas, tornam o computador (mais) atraente.
Sem importar a carga, o computador permanece frio e funciona de forma silenciosa a maior parte do tempo. Este último se aplica desde que a ventoinha pare ou funciona a uma velocidade muito baixa. De outra forma, você pode ouvir um baixo ruído de assobio. Isto não deveria acontecer em computadores desta faixa de preços; ainda mais, porque já criticamos isso no antecessor.
O muito veloz NVMe-SSD garante u sistema responsivo. É possível substituir o SSD. Isto requer remover o lado inferior do portátil - que não precisa de muito esforço. A carcaça e o teclado permaneceram iguais: A HP fornece a qualidade com a que já estamos acostumados.
Não é muito frequentemente que podemos dizer algo bom das telas dos portáteis empresariais da HP. No entanto, as coisas mudaram desta vez: A HP incorporou um painel IPS brilhante, rico em contraste e com ângulos de visão estáveis. Inclusive as cores são bastante boas de fábrica.
