Vad synd, HP. EliteBook 820 G3 övertygar verkligen i vissa avseenden, men de negativa intrycken dominerar efter vår granskning. Det största problemet är helt klart skärmen. Det är trist att bara dyrare konfigurationer är utrustade med FHD-IPS-skärmar just nu.
Men de små sakerna är också irriterande, inklusive det oljud från fläkten som vi känner igen från föregångaren, tjutande spolar (”coil whine”) och svampiga dedikerade musknappar.
Det är jämförelsevis små problem som förtar mycket av de positiva aspekterna. HP har gjort ett mycket bra chassi med bra anslutningar, underhållsmöjligheter och mycket bra prestanda.
Enheten håller sig dessutom sval och batteritiden är anständig. Utan tidigare nämnda problem (särskilt TN-panelen som bör undvikas), kunde EliteBook 820 G3 ha varit en riktigt bra dator i storleksklassen. Men vi har svårt att rekommendera den i vår testkonfiguration med tanke på priset.
