Hey everyone. So I had an appointment with the genius and great news. He told me there's no signs of water damage at all. How can two technicians be so far apart on a diagnosis? I did forewarn him that there was a minor accident involving water and he fully understood. Anyways, he checked it all out for me and he's going to keep it overnight to run extra tests, but he said I have nothing to worry about. Going to call the campus technician and ask him how he came to that conclusion, and possibly ask for my money back.
Glad to hear it. The Geniuses are pretty good at double-checking issues in favor of the customer (even if you tell them otherwise).
I on the other hand am about to see if I can get a third, non-faulty replacement logic board...
But congrats.
