Lenovo, ThınkPad L440 20AT004QGE versiyonunu HD+ ekran ve SSD ile güçlendiriyor. Ancak bu makul fiyatlı üst sınıf bir laptop olarak geri dönmüyor. 200:1 kontrast zayıf kalıyor ve DeltaE rengi halen çok yüksek.
Yinede sistemin performansı HDD sistemlere göre daha iyi. İşlemcinin Turbosu maksimum olarak kullanılıyor yani takılmalar gibi sorunlar yok. Oyun dışında en iyi performansı arayanlar için SSDli ThinkPad L440 kısaca harika.
