Water damaged Macbook pro (Mid 2012)

[ajproductionsny]

Hello everyone, I have a Mid 2012 13in MacBook Pro. Water was spilled on it about 3 years. I decided, this past weekend, to give it a go and see if it could be something fixable and have a great laptop for my oldest kid. I went ahead and removed and disconnected the battery then plugged the MacBook to it's charger. I was very pleased to have it turn on!!! I then proceeded to run an apple diagnostic by restarting and pressing down the "D" key. Once the diagnostic was finished I pressed the shut down option to complete it. I then try to turn the laptop back on again but it wouldn't come on. The light indicator in the charger is green. There's no battery installed in the laptop right now. Any idea on what could have gone wrong? I appreciate any help. I consider my self handy with computers, battery removal was done in a clean and static free environment.

Why did you pull the battery 3 years after the spill? You might try putting the battery in it and see what happens.

As for what happened, for sometime after the water was spilled corrosion started building on the surface of boards and under components on the board. It is likely that when you power it up something shorted and now you cannot complete the power up cycle.

Is there visible corrosion on the board or any visible signs of a short?

Hi ZapNZs, no there is no visible corrosion. I will look again. Is it possible to have another component short out even when it started up without a problem?

Thank you for your reply. I can’t think of logical answer to your question. I guess i was so upset I didn’t want to del with it. No signs of corrosion though.
