Hey everyone, I have a macbook pro 2009 version 15" that had some liquid accidentally spill on it. After a long time of drying out and internal clean up by me, the system only powers on with the power adapter plugged in (functions flawlessly and is quiet) Is it simply a battery that needs to be replaced, or does the fact that each time I restart, the system time is reset, point to something else? Is there a CMOS battery or something that should work even if the battery is dead/non present as far as the system time goes?? Anyone know anymore? I would just like to get some advice/feedback before dropping $100 on a battery y'know Thanks a lot for your time!!!!!!
