not really sure about your situation i kinda just skimmed through it. But how is the laptop working now ?
Is there any burning smells from the mobo?
It might be late now, but when you spill stuff on electronics, dry it out as much as u can, take the batteyr out and try to vent it out and dry it with a blow dryer. once you dried all you actually can.... no joke get a tupper wear thing (might be harder for a laptop) and fill it up with WHITE RICE, uncooked ofcourse and seal it up for like 12 hours. The rice will absorb the moisture.
This is known to work on cell phones. I personally got my dad's motorolla phone back to life because of the moisture when he was working out side in teh rain.
And another time when a friend dropped the phone in the toilet (LOL).
Oh ya ps. ASUS FTMFW! 2 year global warranty ...
oh ya did i mention i also have 1 year ACCIDENTAL DAMAGE warranty?
pretty much with an asus, in your situation, you couldve dropped the laptop into the lake, then dropped it down your stairs and then short circuit everything and they would repair the laptop for u and if its not repairable, then replace it with a model equivelent or better
