MacBook Air 13" A1466 EMC 2632 I have a MacBook Air that belonged to my niece. She never took care of it and is dead now. She gave it to me and I am trying to fix it and have myself a backup laptop. I think it has had water damage. She would never admit it though. First, the battery is bad and will need replacing if I get it fixed. I don’t think that has anything to do with the problem at hand though. I replaced the I/O Board thinking that would take care of the problem, it didn’t. When I open the lid or try to power it on, NOTHING happens. I mean there isn’t a sound, a light or anything that happens. It just looks like it is DEAD, which it is. I am thinking that I need to replace the whole logic board. What stops me from doing it is that back when I was working on and building Windows machines when the Motherboard would go bad I would usually get some kind of action going on like a beep, a light coming on, going through initial power up sequence, something. It wasn’t like this where I get nothing. I was hoping that there was something else that it could be that’s damaged that I could replace without going with the replacement of the whole logic board. Do you all know of anything else it could be that I could try before buying a replacement Logic Board? Any help would be appreciated.
I’d open it up and examine the boards LSI (liquid submersion indicators and see if they have turned red. Look for evidence of corrosion. The logic board is pretty well protected from keyboard liquid spills. Minor spills will short out the keyboard and the power on button. Replacing the keyboard would be the first thing I would do on this machine after replacing the battery. I will go into further detail on doing this if you want me to.
