Kısa inceleme: Lenovo Z51-70 (Radeon R9 M375) Notebook

Karışık duygular. Lenovo'nun yeni modeli multimedia sınıfında orta sınıf grafik kartı ile yer almak istiyor ancak ekran ve ses konusunda puan kaydediyor. İyi ofis değerlemesinde bir klavye bekleyen kullanıcılar hayal kırıklığına uğrayabilir. Ancak diğer yetkinlikleri, özellikle performansı ile oldukça çekici.

In review: Lenovo Z51-70. Test model courtesy of Cyberport.

Lenovo'nun söz verdiği IPS ekranlar nerede? Açıkcası IPS ekran olması bu test ünitemizde iyi sonuçlar verebilirdi. TN ekranın bakış açıları ve renk üretimi geliştirmeye ihtiyaç duyuyor. Ayrıc basit kalan klavye ve yetersiz bakım imkanları da eleştirebileceğimiz noktalar arasında. Basit üretim hataları kasanın genel yapım kalitesini çok etkilemiyor. Ancak ses sisteminin sorunlu olması gözden kaçan bir aksaklık değil.

Tüm bunlara karşın kolay kullanımı ve iyi işlemci ile hızlı SSD kombinasyonu artı yönleri.

Touchpad tatmin edici. Yeni Radeon R9 M375, Z51 ailesinin en güçlü üyesi ve GeForce 940M ile kıyaslanabilir. Ancak daha zayıf bir grafik kartlı modeli almanızı tavsiye etmiyoruz, çünkü o zaman bir ofis laptopu almış oluyorsunuz ve klavye bunun için yeterince iyi değil.
