MacBook Pro does not charge anymore the battery after splash of water

Problem seen after a splash of water onto the screen of the macbook pro, and between the screen & keyboard.

1) Symptom :

- macbook pro does not start anymore in normal condition.

- The LED of the charger does not display anymore.

Workaround :

. macbook pro to be connected with the charger - AC Adapter to the main.

. First start requires a SMC reset, then macbook pro can start/stop normally and works fine.

. But : the fan runs always full speed, battery is not detected at all, the LED of the charger does not display.

2) Recovery procedure : insert a charged battery (brand new one) into the macbook pro.

- macbook pro starts/stops normally and works well : with or without electrical power supply.

- fan works normally.

Remaining symptom after recovery :

- macbook pro does not charge the battery.

- The LED of the charger does not display.

I went to an Apple store and we have validated the recovery procedure (see 2) ) which seems to reveal at the end of the day the real issue “macbook pro does not charge anymore the battery”.

My charger works fine with another macbook (LED is green), and a new charger to my macbook pro has same issue : LED is off.

Do you have any clues on what could be wrong :

- Can it be a mother board issue ?

Or is it a magsafe board issue ?

- something else ?

Water damage is tricky, you need to open the system and clean up the remaining liquid and the corrosion that is left. You may need to replace some of the parts (including logic bds.) But you won't know until you see whats damaged.


It's been clean up already (with denatured alcohol) . That was very few white traces of water. As it works fine with new charged battery, I am wondering why do I need to change mother board ? Diagnostic tends to lead to change the megasafe board instead, but I'd need feedback from some guru of mac ...

Jean, Apple moved the power switching logic to the main logic board on this model so changing the DC in board won't help you here. While it's possible the DC in board also needs replacing its not were I would start given the symptoms you've outlined here. Have you run the Apple's Hardware Test yet to see what it discovers? Here's a link on how to access it AHT
