I alway's knew laptops ran on juice....!

Unless you are going to strip it down to clean the stuff out there's
only two options I reckon... either take it in for repair or let it
dry a couple of days at room temperature ~ it may work and it may
not.

There's just no saying what damage has been done or not without
inspecting.

From experience with TV's and videos.... a simple wipe down and a
little warm air from an air dryer worked wonder's..... other's would
require the use of a spade.... "there'd alway's be one that gave
a big blue flash n' almighty bang and then worked".
