So I was going to school one day when my water bottle leaked in my bag and got in contact with my macbook air mid 2011. Tried switching it on in school (I know I shouldn't have but I didn't know then) but it wouldn't power up. Left it out to dry for a few days, even tried the rice method but it didn't work. My warranty has expired and I didn't wanna go send it for repair because it's too expensive here in Singapore. Decided to order some tools off ifixit and when they arrived, I opened my macbook up, cleaned the insides and let it out to dry. Thank god it started powering up again! It would work perfectly fine but then it would shut down unexpectedly after a few hours (even with the battery still full) and then refuse to power up again. Sometimes an SMC reset would do the trick and sometimes it wouldn't. Any advice?
