I do automation work for the national guard. one time when we was on an exercize I took a new laptop dell 830 to the TOC I had to make room on the table to place it. I sat it on a an ice cooler that had its lid on sideways I sat the laptop on it(powered on at the time)the corner dips on the lid and the laptop goes in the ice cooler that was full of water. I took it apart dried it out and what do you know it still works lol
I believe it. Since solid state stuff arrived, that sort of thing, I often take computer cards and simply run warm water over them and let them dry before reinstalling them.
Unless they have coils or old-style looking capacitors.
But I still wouldn’t throw a laptop in the bathtub when it was turned on!
