Hello there, I recently was studying for my exams and spilled coconut water in my backpack, and my Macbook Pro Retina 15" (early 2013) ended up getting water into the left side of the ports (affecting the Thunderbolt and charging ports). I took my laptop for repair with Apple, hoping they wouldn't notice the liquid spill. The Apple Genius told me the charging port was working fine, issuing me a new replacement charger under warranty. He then told me the Thunderbolt ports weren't working, and so he issued a logic board replacement (without opening the Mac up). A week later I get a call from one of the technicians saying there's liquid spill around the Thunderbolt ports, which is why it's not working and some sticky residue on the fans (which he said was not a big deal, it can easily be wiped off) so they cannot go through with the repair under warranty. I then replied back with denying the water damage and that the first technician who looked at it said everything was okay. The technician replied back saying he's sorry and isn't sure if the previous employee opened it up or not to check. The repair costs $647 plus tax originally, but then he brought down the labour fee ($40), making the repair $607 plus tax. (He brought the price down without me asking to do so FYI) Now I was wondering if there is any reasoning I can give to support my claim of the water damage not being my fault? One scenario I was thinking was to say that the first Apple Genius bar employee opened up the Mac and said everything was fine, putting the blame on their end. As a student, a $600 repair is very expensive and since I already spent $300 extra on Applecare, I want to fully utilize it. If I could get any advice on my situation I would greatly appreciate it! Thank you guys so much!
