Test: Lenovo Z51-70 (Radeon R9 M375) (sammanfattning)

Blandade känslor. Lenovos nykomling vill kvala in i allround-divisionen med en mellanklass-GPU, men det är sämre ställt med bild och ljud. Tangentbordet är inte heller i toppklass, även om många andra aspekter är riktigt bra.

Var är alla IPS-skärmar som Lenovo utlovat? En sådan hade i alla fall sett bra ut på vår testmaskin. Istället får vi leva med en medioker TN-panel med mycket begränsade betraktningsvinklar och en färgåtergivning som lämnar övrigt att önska. 

Det ganska dåliga tangentbordet och de otillräckliga underhållsalternativen kan också nämnas medan vi är igång och klagar. De mindre bristerna i det i övrigt väldesignade chassit kan vi bortse ifrån i en konsumentlaptop. Däremot kan inte det defekta ljudsystemet ignoreras.

All hårdvara fungerar å andra sidan utmärkt, främst tack vare en potent processor och en snabb SSD. Pekplattan är också bra. Det nya grafikkortet AMD Radeon R9 M375 kan utan problem konkurrera med jämförbara kort, som Nvidias GeForce 940M. 

Vi avråder från att köpa en version med ett klenare grafikkort, eftersom datorn då hamnar i kontorskategorin, och tangentbordet är helt enkelt inte bra nog för det.
