My keyboard has a section of keys damaged by what is apparently liquid damage. At the Genius Bar they told me they would send in it as covered, but if the repair team found that it was accidental damage I would be charged $755 for the repair. How do they decide? I am not so hot on sending it out only to be told I need to pay that much, which is not really feasible right now. Would liquid damage not inherently be accidental? What are the provisions in the warranty for such an event? Thank you!
