Sorry to be the bearer of bad news, usually liquid spills in laptops damage the systemboard. If you spill liquid, the usual advice is to turn off immediately and dry out slowly before trying to power on, or even better gwt someone that knows about them to take it apart and dry it out.
Unfortuately if liquid hits the systemboard while the unit is powered it's often too late for any of these actions :-(
