I have a 13" MacBook Pro, spilled water on it, took it apart, dried the logic board, put it back together and it works fine. Only problem is, using the default charger, it says not charging for a few seconds and then the light on the adapter turns off and the computer is no longer even plugged in. And the screen dims its normal amount for when you unplug it. However, when I use a replacement adapter from my other MacBook, it will stay plugged in and the light on the adapter will stay green, but it will stay "not charging". What part should I replace to get this up and running normal again?, I'm sure it's the logic board, but that's costly. Also, if I just use the replacement adapter, and it stays "not charging" will it die? Or will it stay on as long as I leave it plugged in? Please help.
