Good morning everyone. Hoping someone out here may be able to point me in the right direction. I'm working on my daughter's mid-2009 13", 2.53 ghz MBP that suffered a water spill. The case was closed when the spill occurred but it may have been still powered on with the battery. After the spill, she dried it out and was able to restart it a few days later. However, that only worked until the battery died so it's obvious the MBP is not getting power from the 60w MagSafe adapter nor is it charging the battery. Thus far I have disassembled the MBP and cleaned the logic board with a 94% solution of alcohol. There were no obvious signs of a spill on the board and the limited number of liquid sensors were still white. Cleaning did nothing to bring it back to life. I also changed the MagSafe board which was the only area to show any sign that liquid may have been in contact with it. Still no luck. If I perform a SMC reset I can get the fan to power up and the DVD player to initiate but nothing else. By the way the MagSafe adapter shows a very dimly lit green light. This morning, for the heck of it I tried starting it with battery power only and I got the fan to start but nothing else. I shut it down and took voltage readings at the battery and it was registering approximately 8v. So I started it again (battery only), it ran for about 15 seconds and then shut down. Took voltage readings again and this time it registered less than a volt. I also took voltage reading across the logic board (attached, the red readings are with the MagSafe plugged in but without the machine running, the white are the readings with the MagSafe plugged in and after a SMC rest was performed), but I don't know if these are the readings I should be getting. Can anyone out there point me in the right direction.:confused:

Some additional info. Performed another SMC bypass yesterday and left the MagSafe adapter plugged in overnight. When I took voltage readings at the battery I found the following, o volts on pins 1-3, 3.4 volts on pins 4, 6, [in 5 had voltage that flucated beteeen .15 - .32 volts and pins 7,8,9 all registered 9.89 volts.
