Q: Macbook Air Logic Board Failure

So here's my story: I bought a few months used Macbook Air Mid-2013 11" (A1465) last spring. It was big money for me, but I was hoping that atleast it would be a reliable tool for many years (basing on the Apple reliability reputation). Going almost a year without issues, last week happened this. I was studying late, and when I went to bed, the battery was almost empty (~5%). I just put it to sleep. When I woke up the next morning, the Macbook had ran out of power, and when I tried to charge it, it didn't do anything. I googled it, and tried many things, like SMC reset and warming the charger. I even tried a different charger, but nothing.

So I took the Air to a authorised Apple reseller (Valge Klaar) in Estonia for diagnostics. And yesterday I got a text from them that the logic board is dead, and the replacement would cost 480€ (570$). I mean, how is this even possible that a mother board just randombly dies? Especially on a great reputation company device...

I was stunned by these news. So here I am now, and because I can only dream about paying that sort of money right now (or in the near future), helpless and hoping for some kind of help from you guys. The laptop is over a year old, so the guarantee is over by a month or two. Should I just sell it for replacement parts? I must admit I am quite disappointed in Apple
