I got a call last night for help with a liquid spill incident. The client was working on his MacBook and accidentally knocked the water bottle over, right on his laptop. Like most of us would react in such horrify scenario, he kept trying to power the MacBook on to see if it still works. However that might be the worst thing to do right after a liquid spill.

Liquid and electricity simply don't mix... if it's wet, then it's bad. The logicboard in the MacBook will be fried if enough liquid get to where there is active current. So to limit the chance of this happening, cutting the power supply to the laptop is the best thing to do. It will greatly increase the chance the MacBook would work again after it's dried out. Typically 48 to 72 hours for water spill, and 96+ hours for other liquid spills.
