My motherboard get wet

was it on when it got wet? how wet was it? what was gthe liquid? its possible no damage has occured. make sure you leave it open and let it dry before trying to power it on. if it was something sugary and more then water you may have to replace the board, it might work but will give you issues. if it was on and soaked the computer is most likely gone and wont be recoverable though your hard drive might be still ok

Do not turn on your laptop or it will fry the components.It must be disasembled to dry it off.This is a serious issue that can result in a very costly repair.Have a tech.take it apart to clean all the internall parts.
Good Luck.
