Help needed on Lenovo G-560 laptop..

I have chosen the below model .

Lenovo-G560 59-050863
Rs.24790

My concern now is,

#Does this come with a DVD writer ?
#How good is the onboard gfx? (will it play 1080p movie?)
#How worst is the 5400rpm hdd ?(when compared to 7200rpm drives)
#How is the after sales support of lenovo in India ?

#and the most important, what is the back up time given by its 6 cell battery ?

Planning to buy in next few days.. guide me..
