Answer 1

Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.
