What power related component should I replace next?
I accidentally spilled water (from a Dasani water bottle) onto my MBA (on the keyboard) while it was on. I immediately turned it off, wiped any visible water off, held it open and upside down (with keyboard toward floor) to let gravity work it's magic. Then I put it in a large plastic bag with rice and dessicant pouches for 2 weeks.
Unfortunately, OSX indicates it takes roughly 20 hours to charge the battery to 100%, although a more realistic number is around 48 hours.
I've done PRAM and SMC resets and replaced the battery and the I/O board - but still the same problem.
