I want to buy a notebook MacBookPro 13" used(second hand).
The model that i want to buy is a 13" non-retina(late 2011 ) with i5 2,4 8gb120 SSD.
What are the major objectives that i need to check before i should buy:
Is there any way to verify the autenticyty of the product on-line.
I guess i need to check the Baterry, HDD, the response time, heating time, and so on.
Is there any betchmark to run to chech performances?
MacBookUser please advice me.

Thanks a lot.

You could run Coconut battery on it to see what sort of shape the batteries are in. You can check the serial for warranty information.

A benchmark will do little to resolve much on an MBA.
