You need to contact that institution -- Dell won't have records going back 13 years.  
Dear Dell team, I had buy a Dell Vostro 1014 laptop in 2010 from Lloyd Institute of Management & Technology. But due to some reason, I did not have the invoice bill of the laptop. It is my humble request for you to please provide me copy of the Invoice bill. I'll be thankful to you for this. With Regards, Abhishek K
