I have a 2013 MacBook Air, 13-inches, with upgraded RAM and 256-gigs memory. I paid $1500 for it brand new a year ago. On Sunday the computer started acting weird and would go dark after random periods of time, none longer than an hour and most within 2 to 3 minutes, sometimes immediately. It's basically non-usable. I took it to the Apple Store and the very nice Genius tried to run tests but the tests failed because it went dark. After opening it last night they said it has possible liquid damage, which is bizarre to me because I would know if liquid got into my Air. There are 2 adults in my home and no children. It has a password so I am the only user. I'm completely puzzled. Today I went and looked at it. I saw the dried liquid, which was brownish in color, but I questioned whether it was liquid at all--some sort of electronic leakage maybe??? An even nicer Genius said he would submit it to their Repair Center recommending it be covered under warranty, because the liquid damage is "minimal" (his words). But he warned that the Repair Center could say it's not covered and charge me $755 to fix it. Would you pay that much to fix a 1-year old MacBook Air that cost $1500? I was already thinking my next laptop would be a MacBook Pro so I feel foolish putting more money into my Air. I don't know what to do. I feel like that's too much money. A 3rd party repair place said they could do it for $350, but would you trust them? What to do???
