Lenovo har nu bättrat på sin ThinkPad L440 med en HD+-skärm och SSD. Men det räcker inte för att förvandla den till en billig premiumdator för proffs. Kontrasten på 200:1 är usel och DeltaE-färgskiftningarna är fortfarande alldeles för höga.
Utmanarna med samma skärmupplösning, Latitude 3440 och ProBook 640 G1, har mer att erbjuda här (bättre kontrast). En ProBook med en SSD kostar bara några hundralappar extra, och även om Latitude 3440 har färre proffsfunktioner (inmatningsenheter, gränssnitt, chassi), är den billigare och har GT 740M-grafik.
Oavsett det tar vår testmodell täten prestandamässigt eftersom den konkurrerar mot HDD-system (Latitude 3440, ProBook 640 G1) som även använder lågspänningskretsar i vissa fall (Latitude 3440). CPU-turbon är maxad, utan strypning. Om man vill ha bästa möjliga prestanda, bortsett från i spel, är ThinkPad L440 med SSD ett bra alternativ.
