If your laptop accidentally gets wet, immediately cut off the power supply and shut it down. Try to avoid getting an electrical static shock; carefully remove the power adapter cable. Remove the battery and any peripherals that you have attached to the laptop. Open your laptop and flip it over. Let all of the excess liquid drain out of the case. Then locate a flat surface, to allow your laptop to dry out.
Many people believe that, when electronic devices--such as laptop computers and cellphones--get wet, they are ruined forever. This may not be the case, if the circuit board on your laptop gets a little wet. Plain water is less damaging than salt water or liquids that have been sweetened with sugar or honey. Salt water is very corrosive, and sweetened liquids can damage the components on the circuit board, even if there isn't any electricity flowing through your laptop. If a small amount of plain water gets into your laptop, it may be fine, but let it completely dry out, before trying to power it on.
Remove The Hard Drive
Use lint-free cotton cloths or paper towels to dry off the surface of your laptop. Don't forget to dry off the power supply cord and battery, too. If your laptop happens to get soaking wet, you should also remove the hard drive. However, before you start taking your laptop apart, make certain that you read the user's manual that came with it to learn how to properly remove the hard drive. Or, go online and check the manufacturer's Website for instructions on how to remove the hard drive from your laptop computer.
Let Your Laptop Dry Out
Place a towel on a flat surface and lay the laptop upside down on top of it. Let your laptop dry out for approximately 48 hours before you try to power it back on. Make certain that it's completely dry, and check to see if there is any visible moisture on the surface. Then reinstall the battery. Plug the power supply cord into your laptop and power it on.
Contact A Computer Technician
If you're having problems getting your laptop to start up, contact a computer technician that does laptop computer repairs, to help you troubleshoot the problem. He will be able to perform various types of electronic tests on your laptop's circuit board, power supply cord and battery, to determine if the devices are working properly.
