MD313HN/A and MD313LL/A are these models the same , the former is listed cheaper on ebay

I may be wrong, but I've only seen mention of the former on Asian-based websites, especially retailers in India. The latter, on the other hand, is sold on Apple's website for North America. Could have to do with Superdrive zoning, or some other internal difference. Don't know for sure, as a matter of fact... 😊

The letter suffix following the number for each model indicates the country or market where it was made to be sold. This may affect the DVD drive region, keyboard markings, and perhaps other localization features. LL/A is the suffix for USA models. I don't know where HN is — perhaps Hong Kong.

You'll only have an pApple warranty if you buy the machine from an authorized Apple reseller brand new, or if it's a used computer with some of its original warranty period remaining. There is no way you can have the machine checked for "genuinity," whatever that means, until it's in your posession. You can check for remaining warranty on it, if you can get its serial number from the seller, by entering that number on this page:
