Rick Fink, the first thing you want to do is to stop using it. Remove the battery and use [guide|25829|this guide] to get to the motherboard. Then clean all your parts with 90%+ isopropyl alcohol and a soft brush. Check for obvious damage like burned, charred looking components. Once you are sure it is cleaned, '''replace ''' the battery and see what you get. Water damage is the hardest to fix since you do not know ahead of time which parts have failed. It does not matter much on how long or how deep the exposure was. It matters what may have gotten shorted out. Hope this helps, good luck.
