Lenovo fortsätter sin lyxiga Yoga-serie med Yoga C940-14IIL och har för första gången utrustat den med de senaste Ice Lake-processorerna. Det här är en väl utförd evolutionär uppdatering.
Det är ingen tvekan om att nya Intel Core i7-1065G7 är hjärtat i denna Yoga-platta. I fråga om CPU- och i synnerhet GPU-prestanda innebär den nya plattformen en stor förbättring, vilket gör Yoga C940 lämplig för lättare gaming. Detta har gått att uppnå utan att värmeutvecklingen eller ljudnivån ökat – faktum är att båda istället har minskat. Batteritiden är fortfarande bra. Jämfört med Yoga C930 har den en ny och mer ljusstark FHD-skärm, vilket definitivt är en välkommen förbättring. Utöver det har Lenovos dator kvar många goda egenskaper från sin föregångare, såsom den lyxiga metallkonstruktionen, den inbyggda stylusen och det starka fyrdubbla högtalarsystemet.
Den har knappt några svaga punkter alls. En av få är definitivt bristen på portar samt en mindre mängd spoltjut. Det är dessutom onödigt svårt att öppna Yoga C940 (eftersom skruvarna är gömda under gummifötter). Det hade också varit trevligt om Lenovo erbjöd ett matt skärmalternativ och om LCD-panelen kunde nå upp till den utlovade ljusstyrkan på 400 cd/m².
Lenovo gör i det här fallet inte några avgörande fel – vilket är anledningen till att Lenovo Yoga C940-14IIL troligen kommer hamna på många önskelistor den här julen.
Vi tycker inte att de svaga punkterna är avgörande utan kan istället helhjärtat rekommendera Lenovo Yoga C940-14IIL. Det är en lyxig laptop som erbjuder hög kvalitet och stor flexibilitet, vilket målgrupper som studenter kommer uppskatta. Dell XPS 13 7390 2-in-1 har fått en stark konkurrent.
