I have a macbook unibody that got coffee spilled in it. The good news is that it works perfectly on battery. But, charging and powering the macbook only on the adapter doesn't work. I verified that the dc-in board and power adapter are working fine. Buying a new logic board is very expensive. Therefore I want to bypass the charging circuits of the macbook and run power directly from the power adapter to the battery connectors. My question is do you know what the pinouts are for the battery? Or, do you have any useful suggestions? Has anyone tried this before?

Welcome to our forums!

Three words: Don't do this. Don't even think about doing this. I don't know you and I don't know how much you know about electrical engineering or power supply design, but from somebody who does: don't do this. I don't think anybody here would want to be responsible for giving you "advice" that completely destroyed your machine, or worse yet, caused a fire. Take it to an Apple store and get it repaired or replace it. See our sticky (http://forums.macnn.com/69/mac-noteb...r-beer-liquid/) for more details.

I'm betting you could strip the machine down and wash the board in distilled water. Might fix the issue, if the problem is a short.
Just be sure to let the board dry for a while.
