In review: Lenovo ThinkPad E450 20DDS01E00. Test model provided by CampusPoint.

Med ett totalbetyg på 80% verkar Lenovo göra många saker rätt med ThinkPad E450. En SSD kombinerad med en strömsnål 15-wattsprocessor säkerställer lång batteritid och tyst drift. Full HD-skärmen ger dig mycket skärmyta. De bra inmatningsenheterna – ett arv från den dyrare T-serien – har bra feedback och dockningsporten Onelink förstärker upplevelsen av en professionell bärbar dator, för studenter.

För det är just denna målgrupp som Lenovo hade i baktanken när de skapade en modell med Radeon-grafik. Dessutom har datorn en SSD i form av en 2,5-tumsenhet från Samsung.

Trots det har vi inte den perfekta 14-tummaren framför oss. Skärmens låga ljusstyrka, speciellt under batteridrift, stör oss oerhört. Den matta ytan hjälper inte om skärmen helt enkelt är för mörk för utomhusjobb. Underhållmöjligheterna (fast batteri, fläkt som inte kan nås för rengöring) är ganska dåliga. På köpet får du en trasig bottenlucka, eftersom krokar bryts och plattan spricker.

Om du kan leva med bristerna, nöjer dig med en mindre snabb SSD och inte saknar starka färger är E450 en 14-tummare som kan vara en trogen följeslagare i universitetslivet till ett attraktivt pris.

De som vill ha en bättre bildkvalitet bör överväga Acer Travel P645-S – en 14-tummare som är tillgänglig i olika konfigurationer och prisklasser. Om du inte har något emot en lite tjockare modell är ThinkPad L450 en liknande modell med bättre underhållsmöjligheter.  Även om inte heller den har en perfekt FHD-skärm har den bra betraktningsvinklar och bättre färger tack vare IPS-tekniken.
