MacBook Air A1466 Faulty Power Button

[jspring]

Hi,

I have a MacBook Air 13" A1466 that is a friend of mine who split green tea and honey all over it leaving sticky residue over the logic board and keyboard.

I have taken apart the computer bit by bit cleaning off any residue with Isoprene and electrical contact cleaner so it looks perfectly fine now. However, the keyboard is still quite sticky and obviously I don't want to have to take the whole laptop apart to find there is nothing really wrong with the keyboard.

When I plug in the charger, it light's up green and then turns to orange (with battery in laptop). I have also tried without the battery in, incase the battery is causing the problem and the magsafe indicator just stays green.

The whole problem is that the computer will not turn on - pressing the power button on the keyboard does nothing. I saw this post (Where is the power jumper on the logic board? - MacBook Air 13" Late 2010 - iFixit...) and tried to find the solder points on my laptop to start it up but I cant seem to find any instructions for an A1466 model.

If anyone could help that would be much appreciated as I need to boot this up to see if there has been anymore damage. I have tried to see if I could boot it from a wired keyboard but the one I have doesn't have a power button on it so nothing really happened.

I have been directed on iFixIt to locate the 'power pads' on the logic board however the diagram someone gave me didn't correspond to my logic board for an A1466 model.

Thanks a bunch!

"Looking perfectly fine" has just about nothing to do with determining if an electronic device should be operational. Liquid spills cause short-circuits. Which electrically...destroys electronics within milli or nano seconds of coming in contact with the liquid. In many cases...this short-circuiting leaves no visible damage. So cleaning the residue may help to make things look better...unfortunately it will not reverse the electrical damage that is probably present.

The whole problem is that the computer will not turn on - pressing the power button on the keyboard does nothing.

I'm afraid that you may be looking at things a little too simplistically. There is a very very good possibility that the power button is fine...and the reason why the computer will not turn on is because the logic board has been damaged.

Give this thread a read as well. Liquid spills are not kind to laptop computers:

Hi Nick,

Thanks I have looked at that. Although it may not power on it MAY be due to the damage to the keyboard. Hence I asked if anyone knew the solder points to short the logic board into starting - therefore I can ascertain whether the mac works or not.

What I'm suggesting is...the power button is fine...and the reason that the computer will not turn on is damage to the logic board. So there is no reason to "short" anything. The power button is very simplistic...and rarely gets damaged in a liquid spill.

If you REALLY want to try what you suggest. Just open up the computer...trace where the power button plugs into the logic board...then short the pins. But...if you cause additional damage...it's on you.

More than likely...the liquid spill damaged the logic board. If this is the case...start looking for a new computer...since it's usually not cost-effective to replace the logic board. Hopefully I'm wrong...but the statistics are with me.

Good luck,
