A friend just spilled a few drops (like 3 or 4) of coffee right at the edge of the trackpad of his 2011 MacBook Pro. He wiped it off, but some did go into the crack and the screen started moving around erratically for several seconds. When the movement ended, he tried to use the trackpad - and it worked for a few seconds - but then the erratic shifting of screen shots resumed. He turned it off, removed the power cord, and is planning on keeping it off for a few days. Any further guidance or advice on what to do at this point? Any predictions on nature/extent of damage? Thanks.
