Test: HP EliteBook 820 G3 (sammanfattning)

Andreas Osthoff, 05/15/2016

För dålig skärm. Den tredje generationen av HP EliteBook 820 är en kompakt bärbar dator med 12,5-tumsskärm, riktad mot företagsmarknaden. Vår testmodell är tyvärr obalanserad, för trots bra prestandan ingår också en undermålig TN-skärm. S.k. "coil whine" förekommer också.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29.2 ms ... rise ↗ and fall ↘ combined↗ 12 ms rise
↘ 17.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 69 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
58 ms ... rise ↗ and fall ↘ combined↗ 24.8 ms rise
↘ 33.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 91 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (43.4 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5069 (minimum: 43 - maximum: 142900) Hz was measured.

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.
