I acquired a 2015 13" MacBook Air that had a water spill. It boots and works fine, other than the following... - Keyboard doesn't work. - Trackpad doesn't work. - Fans spin up to full speed on boot and never wind down. Plugging in an external keyboard and mouse works fine. The USB ports are fine. Seeing as I paid nothing for this computer I'm wondering if it's worth repairing. I know only the Apple Store can tell me for sure, but I'm wondering if it's even worth the trip to ask. Thanks!
