Liquid was spilled on the unit.
The user said it was working fine until the battery ran down to nothing after the spill
When you first put the charger on it turns green then goes to orange.
Tried a second charger..same result.
Took the Logic board and IO board out and went over them with alcohol. There were no apparent burn marks etc. Same result
If I do a SMC reset I see the power light, on the battery charger go to green then back to orange each time. So this tells me the power button is for sure working.

Kind of wondering what to try next or is this for sure telling me the Logic board is dead.
FYI I do a lot of repairs on Windows style laptops..not a lot of Mac laptops
Thanks,
Sam

Did you test the battery?

Since the machine "ran down" rather than quit immediately, damage from a high-current discharge isn't as likely as failure of a more subtle nature. Can't be sure at this point whether it's the battery, I/O Board, or MLB that might be dead, or some combination - any of those could pull the machine down.

The Magsafe chargers will reset if disconnected from the wall for 60 seconds - it's worth a try. Reset, then let it try to charge for at least an hour.

Thanks for the reply,
I did try a second charger as well as what you suggested, leaving it unplugged for an hour.
I did also try turning it on with the battery disconnected. Thinking this would rule out the battery? Or do these need a battery connected to even boot up.
Thanks,
Sam

Same exact problem here on a mid-2013 MBA. Small amount of tea spilled on it, same exact symptoms as described above.

I had a similar issue with my 2011 Pro. The water spill was near the laptop but not a direct hit. It was the MagSafe connector part that had broken.

In addition, it runs fine when plugged in. Battery states not charging. Shows at 44%, slowly running down, won't run if unplugged.

Hey, just had my MBA inspected by local Apple store. I have similar issues as you. In my case, they saw no evidence of liquid damage and said it is most likely the I/O board. Quoted my like $17 or so for the part and $80 in labor.
