MacBook Pro on table with water
Well if you have a plastic box put the mac &amp; rice in that, shut the lid and put it somewhere "gently" warm. 24 hours minimum - give it a chance as it sounds like water got deep in...

But if you can get it to someone who can take the cover off to clean and dry it out that would be better...

Be thankful it was not beer or (white) wine - they leave residues that make it very unlikely that they start again (guess how I know :), done 3 water, wine &amp; beer - only one that survived was the one with water...), but water there is a chance...

Best of luck with it.
