What do you do if your mac book pro gets wet?

Answer 1

Immediately turn it off, disconnect the power, and if it has a removable battery, remove it. Allow the laptop to fully dry, both inside and out, then you can power it back on. The key is to not have electricity running through the circuitry while water is present.

Answer 2

Put it in a tube of rice or try recharging it for 24 hours.

Answer 3

Water will probably short it out and damage it, you can try drying it out, but in all likely hood it is already shot. Take it back and have it replaced.
