On Tuesday night some wine was accidentally spilled on the keyboard of my 2015 MBA. It wasn't much wine, and it was mopped up quickly, but there was a worrying crackling sound from the top right corner of the keyboard area, and the power was affected. By this I mean, it would switch itself on and off, without regard to the power button and it would only charge intermittently. I left it open and stationary for 2 days afterwards, but now it won't power up, even though it is fully charged. Is it worth taking to an Apple Store? Is it a write off? What can be done? All advice gratefully received.
