spilled coffee (am i the first to do this??)

1...spilled coffee on keyboard
2...let the thing dry out
3...wouldn't start or even light power light

4...took apart and cleaned off coffee from circuit board with isopropal alch and tooth brush and let dry
5...eureka...IT LIVES
6...after 1/2 hour died again
7...next day...works for 20 minutes and dies

what should i do...is there a log that will tell me the why it is failing?

might it self heal??
