A:AnswerHello,
I am not the seller of these Dell Systems but since I do specialize in Dell computers, I will help answer questions when it is appropriate. This refurbished Inspiron 15 (35210 weighs approximately ~5.1 lbs.
Hope this helps!

A:AnswerI don't know exactly but you have to get a new hard drive and the certain type of O.S. you want. Then load the O.S. on to the hard drive by replacing the old one with the new one. Hope it helps!
