I'll try and make this very long story short. I just adopted a kitten, and she was very interested in a cup of water next to my early 2015 MacBook Pro (Retina, 13-inch). The water wasn't right next to the computer, but a small amount go on the left side of the keyboard, the charging port, and the slots on that side. I've had it diagnosed and was told I am pretty screwed. I was given two options: 1) $850 fee for Apple to go in and replace everything that was touched by the water, or 2) buy a new computer for a few hundred more and avoid wait-times and the measly 90 day warranty. I bought a new computer and took my old one home as well. Because I was curious, I plugged it in. The computer is completely functional (ironically, I'm currently using it!) with one very unfortunate "but." The computer's power system was somehow damaged. The battery percentage says "96%", but without constant power from the wall it dies instantly. The Mac is informing me that the battery's condition is "replace now." I need a reliable computer for my job. Is there any chance I can save this computer without throwing more money away? Or is my best option to keep the new one? Any chance that I can sell it for parts...?
