i want a gaming which can give me reasonable amount of battery back up (ideal would be 3 hours) these two are laptops which i have shortlisted. i know that DV6 is powerful but i can compromise a little in performance for a longer battery life. Q1- so i want to ask which one is better & why? Q2- i have read that 1211ax gives battery back up of just 1 hour 30 minutes under load (source techtree) which is way less than acceptable but i don't know about the battery back up of lenovo. Q3- i have also heard from my frnds that lenovo laptops are not good in build quality, is this true? Q4- do DV6 one has led backlight?
