Hello everyone .i purchased lenevo ideapad z510 in 2014 and im still using it .It works very good in terms of prformance with amazing battery backup upto 3.5 hrs-5hrs, this laptop is powered with intel core i5  and  8gb DDR4 ram screen resolution 19201080 is good and 15"6 ips display is enough for every work either its gaming or work.For gamers like me this laptop is amazing with 4gb dedicated graphics which enables you to play higher graphics game easily on your pc. Weight is not much so easy to carry around with you and its doesnt have too much issues so I love this laptop.
