    I know this is a very common question but i couldn't find a solution in other threads. I have a Macbook Pro A1286 with the internal battery and about a month ago my little cousin spilled water on it. It stop working but i recently disassembled it, since it had no warranty after the spill, cleaned up the keyboard and the logic board and it started up. Everything works perfectly except from the battery. I doesn't work at all without the power cable on and the led light is always green. In the status bar there is a message saying (Not Charging) and the condition of the battery says Replace Now.
    In the system profiler i get this info:

    +1. If you don't say anything, Apple might replace it for free.

    Macbook PRO A1286 Battery Problem

    I also had this problem from a spill on my 15" 2.5 GHz macbook pro. The battery would not charge no matter what I tried. I did ALL the fixes everyone suggested. Replaced the logic board, reset SMC, etc. Nothing worked. I even took my macbook to the apple store and even they could not fix the problem. At this point I just got mad :mad: and took the problem into my own hands. I completely disassembled my macbook. I even took out the 50+ screws for the keyboard. Long story short, after extensive testing I discovered the problem. As I was putting it back together, I noticed that the battery indicator light was not on well I pushed the button. At first I thought it was because the battery had no power. Then I disconnected the battery indicator from the logic board. As shown here "step 16"

    And Voila! The battery started to charge. So I figured great I don't really need the battery indicator so I'll just leave it disconnected and I'm home free right? WRONG! Much to my dismay, I later found out that if you leave this disconnected then the mouse and keyboard doesn’t work! Seems everything is wired together and one part depends on another to function.
    So the bottom line is if you are having this problem, check and see if you battery indicator light comes on. If it does not, then chances are you need to have the little Battery Indicator Board replaced. I took me almost 2 weeks to figure this out. I hope this can save some of you a lot of time.

    Hello n00binator,

    Exact same thing happened to my Macbook Air 2010 - Water spill, everything works fine other than the battery that says "Not Charging" and "Replace Now".

    Can you please provide a little more detail on how you resolved your problem?

    Was it only the battery that you replaced? And that fixed your problem entirely?

    Where did you get the battery and how much did it cost?

    I greatly appreciate any advice you can offer.
