Big repair job - it will have to be disassembled and dried out first. Then see what works and what doesn't. You'll then have to decide if the cost of repair is worth it.

Water is a deadly danger to electronic equipment. My personal view, based on many years doing electronic service, is that the laptop should be replaced. There is no such thing as a reliable repair in the event of such damage.

Most of the board was designed to be in water but the water was very special deionized and the board would have been dried under warm high volume low velocity air. Not all parts can be placed in water. Not all companies use water to clean their boards either.

Best is to take apart and try to replicate factory cleaning. It would have been much better if you did that before you tried to turn it on.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

A lot depends on what was in the water. If this was clean tap water then you have a fighting chance of recovering something. If it was dirty ditch water then you have little chance.

Pure water is actually a good insulator provided you dont let corrosion take a hold and with pure water than can take some time. It is all the impurities in the water that does the damage.

But as Jefro says, removing all power and drying it out first would have improved your chances.
