Same happened to me in hospital last week. Had a minor spill on laptop. Quickly mopped it up before it could seep through and cause major damage. Only thing was the mouse stopped working and I can't get away with touchpads. Rummaging through my belongings I found a pack of batteries (Can't think why I took batteries to hospital). Anyway I changed the battery and bingo, no more problems. Pure coincidence I know, but when two things go wrong at the same time it is very easy to jump to the wrong conclusion.
