Water spill on MacBook ... nothing happened?
so about a week ago I spilled some water (half a glass) over my Macbook, shut it off immediately, wiped the water on the screen and the keyboard and let it dry. One day later I ran Apple Diagnostics which reported no problems so far and kept it drying afterwards until now.
Today I opened the Macbook to see what actually happened. Expected corrosion and so on but actually everything seemed normal to me except for a few things, but then again I'm really a beginner so that's why I wanted to ask here (the experts :D ).
Things I noticed (see pictures):
2 case screw holes were blue (corrosion?) -> I tried to remove it with Qtips but since these holes are so tiny, it didn't work. I also checked the surrounding logic board but everything seems normal to me.
The bottom cover had some signs of water spill --> do I have to clean these? And if so, how would I do it?
.. but apart from that I didn't see any strange things. It would be really cool if you could tell me what to especially look for. I tried to find the moisture sensors but weren't able to (how do they even look if they come in contact with water?)
Thanks a lot!
