Will Not Power ON...Replace Logic Board?

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.

Do you have a green light on the charger when is connected or an Amber light, to start.

There are NO LIGHTS on the charging cable at all. Everything on this machine is DEAD right now.

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.

I am not familiar with these indicators. Can you point me to a link where I can see what you are talking about and I will check them very soon and report back.

It would be awesome if a keyboard short would be the reason. I'd much rather replace the keyboard than the logic board......those babies are expensive.

What I am curious about is if it is a keyboard short, wouldn't at least the light on the charger come on and glow red, yellow or green? I would think that something else would work independent of the keyboard and the switch. What do you think?

Thanks for your help.

Look for the white dots (or red in liquid has hit them) on the logic board.

Yes you should be getting something on the magsafe if this machine used one (it may be using a thunderport).

Hello,

I got in it and looked really close this evening with a flashlight and I couldn't see a white or a red color or dot anywhere on the logic board or the old I/O board that I took out.

This is a Model A1466 & EMC2632. I believe it is the Core I5 with the 128mb SSD.

As for the charger, I don't know what type it is, all I know is it is just like the one that came with it. I took it to a local shop that fleeces people on repairing their MAC stuff and had them check my power cord and it is A-OK. I have seen the 3 color lights illuminated on it before it stopped working. So that part of the machine works..right now it's the only part that does.

I'd like to get it fixed but I don't want to throw money at parts without at least having a decent idea of knowing that it'll fix it. If we knew what was causing the problem, I'd start looking for the part to replace it with.

Thank you all kindly for your time and suggestions. I appreciate you trying to help me.
