Battery is randomly recognized and charged
I spilled some liquid over my MacBook. After I dried it for several days it runs fine on a power adapter. The battery is not recognized, X over the battery symbol. But the MacBook runs fine on a charged battery but it does not charge it. So I opened the machine and did not see any spill but I removed the magsafe and the battery cable and cleaned what I could see with alcohol and blew it dry pressured air.
Then suddenly the battery was recognized and it started charging. I turned the MB off and suddenly the X over the battery symbol. So I cleaned again the battery contact. I reset PMU and all the standar stuff. Suddenly the battery was recognized again. Now it is not recognized anymore. I tried another working battery with no success. This battery works fine in another MacBook.
I have read all the threads here I could find about the subject and it seems the next step is a new logic board??
Is this a good question?
