Lenovos ThinkPad P50 var ett bra alternativ i kategorin förra året, men den hade några problem – bland annat de två skärmalternativen, som inte kunde uppfylla våra förväntningar vad gällde ljusstyrka eller PWM-brister (4K-modellen). Årets ThinkPad P51 är Kaby Lake-uppdateringen som använder samma basenhet.
Återigen handlar det om ett mycket robust system med bra inmatningsenheter och tyst kylning. Prestandan är högre tack vare de nya komponenterna, och Lenovo använder äntligen en mycket bra 4K-skärm med imponerande färgskala. Andra problem med P50, som WWAN-problem och kraftigt minskad CPU-prestanda under batteridrift, har också åtgärdats.
ThinkPad P51 är ändå inte perfekt. Förutom några detaljer – inklusive problem med högra TrackPoint-knappen på vår testmodell, dåliga talare och knepigt underhåll – fungerade inte den integrerade kalibreringen nu heller. Kylsystemet är också på gränsen när du påfrestar båda komponenterna samtidigt, och du kan inte utnyttja Xeon-processorns maximala prestanda. Datorns spoltjut (coil whine) märks också eftersom fläktarna ofta är avaktiverade.
Sammantaget levererar Lenovo ändå en mycket bra maskin som de kommande konkurrenterna från Dell & HP kommer att få anstränga sig för att utmana.
