Okay friends I own a dell inspirion 5559 laptop with 8 gb ram and ddr3 dr4.
Now I would like to tell you about the features and specifications.
I have my own true experience with the laptop that I would like to share it with you now.
1) the 1080p screen is very good.
2) the keyboard is robust and so is touch pad.
3) the battery of all laptops is almost average but I am not satisfied by its performance
4) plastic body around the usb charger ports.
Which is prone to damage if you drop it accidantly and this happened with me due to.its poor quality.
5) there warrenty serveice is too good.
I had a 2 year warrenty on the laptop but what I say that the warrenty is void on many other parts of the laptop.
Once my charger stopped working and my laptop was still under warrenty.
I went to The nearest center the guys there were to friendly and repaired it in almost no time.
I also had broken my dvd writer that was replaced in 2 days under warrenty.
At last I should say that every company has its own qualities and cons . But lenovo is too good and should not make silly mistakes to have a bad name.
Thanks
