Macbook Air 13" Won't Power on after Spill

I have a MacBook Air 13” Late 2013 that had a good amount of water spilled over the keyboard.  Immediately when the spill occurred the system was shut down and flipped over.  I've removed the back plate, battery and hard drive (PCI) and was unable to see any sign of water trails.  After checking these items I pressed the power button but the computer doesn't power on.  

I have removed the battery and attempted power on also to no avail.

My immediate thought is logic board but looking for help here first.  Thanks in advance.

If the above post does not work, the water has likely shorted out components. In this case, the computer may not be economically worth fixing. It does not take much water to create a short path on a board or other component.

Performed the SMC reset to no avail.  The LED on the power adapter did change though indicating the SMC reset was completed. No sounds and/or video.
The water has shorted something out. Check Apple for a repair price and make a decision from there.

Prefer to begin replacing parts and see what happens.  Guess I will start with the keyboard...

The led on the adapter has changed from orange to green. Safe to assume the charging system is working properly.
Put it in rice for a couple of days ;)

4 days have passed since the spill.

Keyboard should be in tomorrow.  I've already purchased the USB adapter, thank you though.  I ordered the cleaner just now.  Fingers crossed!

Should have pulled the logic board before ordering any parts.  Getting in a hurry has cost me.  Looks like the water most definitely made it to the logic board.  Only a slight bit but never the less there.  Wonder if this could be fixed with the chemical cleaner mentioned by serialband?

I would use the chemical spray after you've manually dried it out first with some towels.  You may have blown your motherboard already.  Those pictures don't bode well.  You must always take the entire unit apart after a spill.

Certainly.  The machine was brought in for repair 2 days after the spill occurred.  I wasn't the spiller.

Replaced the base which included track pad, keyboard, etc, cleaned the logic board with electronics cleaner, plugged it in and no sound or video. Fan begins to run. If I hold the power button down the fan stops running. If I press again the fan starts again. Same thing happens with or without battery. Also tried smc reset. Led on adapter changes indicating something but thats it.
As I noted much earlier, the water shorted something out. You need to determine whether it is worth repairing or whether it is more economical to replace it.
Was that residue, seen in the images, cleaned off the logic board?

Almost completely gone.  Some could still be faintly seen.  What could/should I agitate the residue with while cleaning?  I just used the force of the spray.
If the water shorted and then wrecked components, cleaning the board is not likely to help.

^^ I order two adapters before your adapter recommendation.  The second I ordered I thought was the exact same as the one you recommended but it still will not fit this SSD.  Can you say if the adapter you recommended will fit the SSD pictured?

First purchased won't work  http://www.amazon.com/gp/product/B00TFANEC2/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

Second purchased won't work  http://www.amazon.com/gp/product/B00TFANFOE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Won't hurt either John.  If the board is faulty then I won't replace it.  Prefer to exhaust all economical efforts first though.
You could carefully scrub those stains out with a damp, not wet, cloth or sponge, then use the spray cleaner again.  You could also spray the cleaner, then wipe it while it's still "wet".  I don't think it was just water, or it was very heavily mineralized water.  Water generally doesn't discolor a motherboard like that.

A "short" circuit happens when something connects between two other circuits.  At these low voltages, it may not have created an "open" (disconnected) circuit in one of the chips.  You may possibly salvage it by removing the short, such as cleaning those deposits off those sections in your pictures..  There's no guarantees since, sometimes, the short happens at voltage sensitive circuitry and even the slightest amount extra power would destroy it.

At high voltages, the "short" will most likely create an open circuit by overloading the current handling capacity of the internal wiring.  If your spill was at the power input section, you may be out of luck.

Thanks again.  Can you address the adapter needed to access the files from the SSD?
What didn't work with them?  Did they not fit?  Did the SSD not read?

From the looks of the Descriptions of your adapters, they're tied to specific models from 2011 and 2012.  It seems that Apple changes configurations every few years.  You may have to look for a newer version.

Thanks for all the help.  Still need an adapter that will work with the SSD...
Did the accepted answer get your laptop running?  I thought it still did not run and several said water would short it out.

Accepted answer was the most helpful IMO.  Laptop will need a logic board.  Haven't decided if I'll repair yet.
