Spilling a cup of coffee or wine on your laptop is one of the worst feelings imaginable. It happened to me once and I learned my lesson. Yes, we all know better to not having our drinks close to the laptop but sh*t happens. So what to do if you spilt liquid onto your laptop? Well, the most common mistake people make after a liquid spill is turning on the computer to see if it still works. Why is this a mistake? Liquid and electricity don’t mix. There are more chances for further damage. So don’t turn it on. Put a clean cloth on the keyboard and turn the laptop upside down on a ledge of a table to drain the water/milk out. After 4 hours or so, take the cloth off and move the laptop to a well ventilated area for it to air dry for another 48 hours. Then you can attempt to turn it on.
Best to ensure that no damage to your keyboard or logic board is to seek professional help. In my experience, unless you clean the logic board with rubbing alcohol there will very likely be residue and corrosion in the long term.
