MacBook Pro won't turn on after logic board replace. Dim green light.
I just replaced the logic board in my late 2011 a1278 Macbook Pro Unibody. It was diagnosed dead by apple so I thought I could replace it myself. So I put it in and it would not turn on. Just shows a dim green light on the charger. I bought the logic board for 250$ off Ebay from a good seller. The board doesn’t get warm at all even after charging for 4 hours so I don’t think it is getting power. Please help me!
