Lenovo Ideapad works well, fast loading os, Lenovo updates, Lenovo Warranty offers, etc what ever ideapad laptop makes work simple and fast. I am using intel i3 with 4gb ram it works great. for people wants to get more performance it can upgrade to 32gb ram, anti dust fan, heating problem is very less compared to others, nice keyboard pattern, sometimes makes to irritate placing backspace was long.Dolby dts sound was provided by lenovo after given updates and regular bios updates available which makes system faster.
