Recensione breve del portatile HP EliteBook 840 G2

Sascha Mölck, 04/07/2015

Non privo di pecche. L'EliteBook è stato un buon punto di partenza ed è stato leggermente migliorato con l'aggiunta del processore Broadwell, ottenendo così una maggiore autonomia grazie ai consumi ridotti. Sfortunatamente, HP non ha ovviato al punto debole - lo schermo.

L'HP EliteBook 840 G2 è in sostanza un upgrade Broadwell. HP non ha modificato nulla a parte il processore. Il processore Broadwell comporta alcuni miglioramenti rispetto al precursore. L'EliteBook 840 G2 consuma meno energia, ha una rumorosità inferiore e temperature più basse, ed ovviamente l'autonomia è maggiore. Per essere chiari: l'EliteBook 840 G1 non si comportava male. I modelli G1 e G2 sono per il resto identici. Entrambi hanno buoni dispositivi di input, ottime possibilità di manutenzione, ed un case sottile e di qualità elevata. Inoltre, entrambi hanno la predisposizione per un SSD in formato M.2 e per il modem LTE/3G. Il modello G1 che abbiamo testato montava anche il relativo modem. Sfortunatamente, HP non ha eliminato il principale punto debole dell'EliteBook 840 G1, riportandolo sull'EliteBook 840 G2: Lo schermo: in entrambi i modelli usa uno schermo scuro e con contrasto basso. Anche gli angoli di visuale sono limitati. HP richiede 1500 Euro (~$1631) per questo portatile; ma uno schermo IPS luminoso e con contrasto elevato dovrebbe essere uno standard considerando il prezzo.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
