Fel sorts kompromisser? Kompromisser i chassi, skärm och konfiguration gör ThinkPad T450 till ett billigare alternativ till den dyrare T450s-modellen. Men frågan är om nackdelarna motiverar besparingen.

Lenovo ThinkPad T450. Test model courtesy of campuspoint.de

Du får vad du betalar för. Det är visserligen ett slitet uttryck och ThinkPad T450 är ingen produkt som tjänar etiketten "billig", men det innehåller ett korn av sanning: Lenovos beslut att använda en så dålig skärm i en bärbar dator med en prislapp på närmare 10 000 kr är svårbegripligt

Den mycket nedslående TN-skärmen är ett ännu större problem eftersom T450 är bra i övrigt. Chassi, anslutningsmöjligheter och inmatningsenheter är nästan om inte helt identiska med den dyrare systermodellen. Dessutom är datorn tyst och sval.

Vår testenhet har en balanserad konfiguration som består av en Core i5-processor, 8 GB RAM och en SSD – en sund kompromiss mellan prestanda och pris. Batteriets livslängd kunde varit något bättre, men den nackdelen kan lätt lösas för en relativt låg kostnad med ett större batteri.

Sammanfattningsvis kanske ThinkPad T450 kan vara intressant för de som har en extern bildskärm till hands. Vi vill varmt rekommendera alla andra att istället titta på T450s eller någon av konkurrenterna från HP eller Dell. Båda finns (åtminstone som tillval) med ljusstarka, högupplösta IPS-skärmar.
