I just ran a whole cup of coffee over my laptop. The problem is that I can't unscrew it because a screw is jammed and it won't open. What will happen now Will the liquid attack the parts?
Wrap it in rice. You will see in a week whether something has attacked.
Switch off, remove the battery, wait until the liquid is gone. You have to open it after a few days. Then take isopropanol and a few cleaning utensils that are anti-static. Clean all of this, wait until the alcohol has evaporated and try your luck.
