This advice is from a co-worker so take it with a grain of salt:
If you ever spill something on your laptop don't turn it off. The heat being produced by the laptop will evaporate the liquid in question. Turning it off increases the risk of the motherboard shorting out when it turns on again.
Bull freaking tweet.
What, the liquid is supposed to remain perfectly non-conductive while the machine is left on, AND evaporate instantly?? Magical thinking there...
The damage comes from electricity shorting between two places, when it hadn't otta do that. Remove the source of electricity = remove the chance of damage.
DO unplug it (not just turn it off - there is still power going inside the machine when off), pop the battery out (portables), and turn it upside down to minimize the chance of liquid draining further inside,
Clean it the best you can, and then put it upside down in some warm but not hot place, like the top of the refrigerator, for at least 24 and better 48 hours. before reconnecting it to power.
If it was something that leaves a residue, like sugared drinks, milk, etc., then you have the additional worry ofwhat the remaining residue will do to the machine. Dissassembly and cleaning with alcohol would be the thing, probably.
Coke and other acidic drinks are even more of a problem because of the damage the acid can do, (Drop an old penny into some coke and see what the phosphoric acid in Coca Cola does to metal oxides.)
