I fear that because the water is in a pretty well sealed space all you will 
have achieved is some nicely warmed water in a pretty well sealed space. You 
need an air flow for the water to evaporate.

Yes, that would be correct. It is a "sealed unit with no customer serviceable 
parts inside". imho that is quite sensible, because an incorrectly repaired 
power supply can be such a danger. Understandably, IBM do not want to carry 
the liability if some fool cooks his ThinkPad, or for that matter,
[him|her]self.

I agree with all the other postings which suggest that you should just buy 
another one. However I can also understand that you might have considerable 
difficulty obtaining one. I do not know anything about the internal layout of 
the Power-Pack ( And I'm not going to open mine to find out - even for 
someone from Linuix-Land - so sorry )  but from the look of my one you might 
be able to open it by cutting aound it with a very fine saw in the slot where 
the two halves join.

Take great care, and do not re-connect it to your computer until you have 
established that it is giving out the correct voltage ( 16v ) when connected 
to a suitable load. ( 4 ohms - 3 x 6volt/20watt car lamps in series )

 If the volatage output is not very close to 16 volts or there is any sign or 
smell of any burning having happened when you connected it before, do please 
throw it away and get another one.
