So my girlfriend spilled some water (about 1-2 oz.) on the top left part of the keyboard on her 2011 13in MBP. Nothing happened initially but then the screen started to flicker a bit, the mouse wouldn't move fluidly, and I got a pop-up saying that the usb port was drawing too much power and they had been turned off or something. I immediately turned off the laptop and dried it as best as I could. Then after letting it sit for a few minutes I took the back off and dried off all the water I could find on the inside. We haven't turned it back on yet and we're planning to wait about 48 hours until we try to fire it up. What do you think the damage could be? And how costly would the repair bill be? I've got some compressed air and some contact cleaner, would these be useful in trying to repair the PCB?
