Long story short, I spilled coffee on my mid-2012 15" retina MacBook Pro.
I took it to the Genius Bar to see how much the repair would cost. I was quoted a flat rate of ~$1300 to replace all the internal components. They will make no effort to diagnose and repair only what is damaged. It's "not what we do."
Since this price and policy is outrageous and my warranty is now void anyway, I decided to attempt to fix it myself.
I have disassembled the computer using the ifixit guide and all parts have been cleaned with DI water and isopropyl alcohol (as a drying agent). They are now drying next to a dehumidifier.
How long should I let the open chassis and disassembled components dry before attempting to reassemble?
