So last night, I spilled about a half cup of milk over my macbook air near the hinge area (had a keyboard cover but nothing protects the hinge/grills) and milk definitely got into the back vent and into the system. The laptop turned off within seconds on its own and I basically tried my best to wipe the milk off and dry it out. I haven't turned it on since because I knew that's never a good idea so it's in a V position with the vent pointed downwards, so now it's a waiting game to see if it'll even turn on. I realize it's likely that the logic board fried (or worse) but I'm trying to see if at least my hard drive would be salvageable, because honestly, that's more important right now and of course, this means I didn't back up either. How likely is it that the hard drive would get destroyed in a process like this? No milk got in through the keyboard but solely through the back vents but the laptop did shut off on its own just about immediately so I don't know if the hard drive would have been affected. Also, any idea how much a logic board replacement itself costs at the apple store? I'm probably just gonna have to buy a new one altogether, maybe if the hard drive is salvageable then I could just purchase the cheaper 11" and they could swap it for me? Any other helpful advice would be awesome. It breaks my heart that I had a black macbook for 4 years and never experienced a spill and then when I own a macbook air for 2 whole months, I pull this stunt. And this seriously couldn't have come at a worse time.
