How can I find out what's wrong with my logic board in model a1466
Hi,
My MacBook Air that was purchased in 2013 just stopped working one day. It's only two years old and I've never misused/overused it or spilt anything on it. I took it to the Apple Store and they they told me there was a problem with the logic board which would have costed me $600 to replace. I would replace it myself but a new logic board doesn't cost much less than what the Apple Store is charging me and I can't afford to spend more than $100 on repairs.
Does anyone know if there is a way to find out what's wrong with the logic board and repair it without getting a new one?
I've read about some simple fixes like cleaning it with alcohol or baking it for 7 mins but I'm not sure if these work for post 2010 models.
MacBook Air, iOS 8.1.3
