Alright so I'll be heading off to college in the fall and have yet to purchase a computer. I want a Macbook but purchasing one new is completely out of the question. So after doing some searching I found some Macbooks between the prices of $150 and $300. The only problem is that they don't work. They "Don't power on" but include what is needed to use them. Should I purchase one and have it repaired by apple? How much would this end up costing me? Please help
