That, unfortunately is a logic board failure error.

Please give us a history of the machine. Is this the i7 model?

Have you seen any anomalies with the screen like artifacts?

Do not buy a logic board until you learn about Flat Rate Depot Repairs!

Talk to us before making any decisions!

This is what concerns me about the 13": https://www.apple.com/support/macbookpro...

I've seen far to many problems with this machine. I think it has the same problems but didn't get included in the class action law suit.

If it does fail call Apple and ask for a "Flat Rate Repair". Total cost for this in Texas, including tax and shipping runs $357.
