Pah!!!! Electronics of today, eh?
I used to repair computers for Hewlett Packard and once had to fix an HP85 (a very early PC) that belonged to a geophysics company. This thing had been caught in a flash flood on the Nile and washed half a mile downstream. It was discovered 3 days later sticking out of the mud in a reed bed.
I took it apart, cleaned all the mud out, washed all the parts with a pressure hose and dried it all with an air line.
Left it all to dry out for a couple of days and it worked first time when I put it back together.
