Mine? My girlfriend at the time, wife currently, spilled some water on the living room table, which apparently got into my less-than-one-month-old MacBook Pro. I was not aware of this and, when my MBP wouldn’t start up, I set up a meeting with the Genius Bar, assuming I just got a defective unit, and they’d swap it out.
So, I get there, they do their diagnostics, and the Genius comes back to me with a look of horror on his face. “I’m sorry to have to tell you this, but there is water damage.” And, sure enough, he shows me the water damage, and it’s unmistakably water damage. There’s a whole trail of dried-out water and the blue-green corrosion on the circuit board where it dripped. He tells me there’s nothing he could do, that’s it requires the replacement of the motherboard/logic board, and it’s basically the highest tier of repairs, $1250 (or something like that.) I bought the thing for like $1600. Well, what can I do? I text my girlfriend-at-the-time/now-wife about the situation, and my puzzlement at the water damage (I really had no idea where it was from, but it was clear that it was water), and she calls me back to explain the happening of the morning. Turns out, there was some water spilled, and it got into the computer. Eh, what can I do about it? I tell them to fix the computer. I need a working laptop; I didn’t care.
The next day (about noon), I had second thoughts. The computer was fucked, right? I can’t make it any worse. This was Apple’s highest repair tier, so I could try fixing it myself and, if I couldn’t, it still would cost me the $1250 or whatever I was going to pay anyway. So I call the Apple Store, and it turns out they haven’t yet sent my computer out. I tell them to cancel the repair and return the computer to me. I pick it up an hour later.
I go to Target and buy the purest isopropyl alcohol they have. I open the MBP, take a Q-tip, dip it into the alcohol, and just start cleaning where the water damage is (evidenced by the blue-green corrosion.) I get it completely clean in about two minutes, put the thing back together, and turn it on.
I honestly did not expect anything to happen. This was just a last ditch, “fuck it” effort. I got the chime. I got the white screen. I got the Apple logo. And, by golly gee, the damn thing booted up fine. I ran diagnostics on it, everything checked out, and I’m writing this post on the same laptop, about two and a half years later. Saved myself over a grand on a $5 solution of alcohol and Q-tips.
