Hi all,
I have bought a MBP Retina mid 2014 that has suffered liquid damage.
The laptop works fine however it will not turn on when the internal battery is connected. I have tried changing the battery with no results. It works fine when connected to a charger.
Have you every faced this problem? If so did you find a solution to it?
Kind Regards,
Michael
Is this a good question?

my first suggestion would be to replace the battery, but seing as you have done that;
water damage has likely caused damage to a PLD used to process the battery. Try using a 99% Isopropyl and a new Toothbrush to scrub hard at the board around the connector. be sure to include local ICs.
If this doesnt work, it is likely a failure inside the IC, which would then need to be replaced. requiring SMT soldering. this is a developed skillset, and i dont suggest attempting it without proper practice ahead of time.

Your logic board has a problem! Charging logic likely has spill damage. You'll need to open the system and carefully inspect the chips on both sides and clean the logic board of any corrosion hopefully that will fix things.
