A pretty standard process for drying out cell phones that get wet is to drop them in a bag of rice. Rice is a desiccant and will assist in the drying process.

My wife submerged a digital camera about 1/3 of the way into salt water. I partially disassembled it (the outside casing, but not the lens / sensor area) and rinsed well with distilled water, scrubbing away some salt deposits with Q-Tips. I wrapped it in paper towels and put it in a container full of rice for a week to dry. It worked fine afterwards.

To accelerate the drying process you might want to consider putting it on top of a dehumidifier.

My wife's laptop (black macbook) got drenched with water once and we just took the battery out and placed it on the dehumidifier for a few days and it booted backup. Still works fine even now.

There are things you can buy at a hardware store that contain extremely hydrophilic chemicals (ISTR calcium carbonate, someone correct me) -- you could put a container of the hydrophilic medium and the laptop inside a sealed container.
