Test: HP ProBook 645 G4 (Ryzen 5 Pro 2500U, SSD, FHD) Laptop (Sammanfattning)

Name: HP ProBook 645 G4 3UP62EA
Brand: HP

Högt upp i luften. ProBook 645 G4 kommer med en kraftfull AMD APU, bra inmatningsenheter och en snabb NVMe SSD. Trots ett prislapp på 9.000 - 10.000 kronor så är enheten inte utan brister: den har dålig batteritid och en mörk skärm med dåligt kontrastförhållande.

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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 detected

100 Hz

≤ 30 % brightness setting

The display backlight flickers at 100 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 100 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

Display Response Times

ℹ

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
26 ms ... rise ↗ and fall ↘ combined	↗ 16 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 10 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 0.1 (minimum) to 240 (maximum) ms. » 59 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
33 ms ... rise ↗ and fall ↘ combined	↗ 14 ms rise
33 ms ... rise ↗ and fall ↘ combined	↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 40 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms).

HP ProBook 645 G4 3UP62EA, recensionsex från: HP Germany.

Läs den fullständiga versionen av den här recensionen på engelska här.

ProBook 645 G4 är en mittenskikts-laptop riktad åt företag. Här har HP använt ett helt nytt hölje. Den som förväntar sig dyra material kommer att bli besviken: Höljet är helt och hållet gjort av plast. Det är bara toppskikts-enheter såsom EliteBook 745 G5 som har ett hölje i metall.

Datorn kommer med en Raven Ridge-APU från AMD, som har mer än tillräckligt med prestanda för alla aktuella applikationer. CPU-delen av denna APU levererar samma nivå av prestanda som Intel-baserade motsvarigheter.

Den inbyggda GPU:n har mer prestanda än Intels lösning (UHD Graphics 620) och kan köra många spel med smidig bilduppdatering. Men de flesta moderna spel går bara att spela i låg upplösning och med låga inställningar. HP utnyttjar tyvärr inte GPU:n till 100% eftersom systemet körs i enkelkanals-läge. Vi rekommenderar att installera en andra RAM-modul för att möjliggöra dualkanals-läge.

En NVMe SSD sörjer för ett riktigt responsivt system. Att byta ut SSD-enheten är möjligt. Men för att göra det behöver du ta bort bottenplattan. Utöver en M.2-2280 SSD går det även att installera en 2.5 tums hårddisk i ProBook 645 G4. Vår recensionsenhet hade inte ett LTE-modem. Men med det sagt så går det lätt att installera ett LTE-modem efter köp. Tangentbordet lämnade ett riktigt positivt intryck. Det passar bra för genomsnittligt skrivande. Tyvärr är det inte bakgrundsbelyst, men bakgrundsbelysning finns som ett extra tillval.

ProBook visar upp nackdelar som en företagslaptop inte bör ha.

Den matta IPS-skärmen har bra betraktningsvinklar. Men den har också låg ljusstyrka och ett dåligt kontrastförhållande. En laptop som kostar 9.000 - 10.000 kronor bör erbjuda mer än så. Batteritiden är dålig. I vårt realistiska WiFi-test så höll ProBook mindre än fem timmar. Den borde ha klarat sig minst 2 - 3 timmar längre.
