After the collapse of the air conditoner upstairs of my dorm I consider myself lucky because my macbook pro retina seems to work well.However there are some questions that popped to my mind about the water - macbook pro,I mean the questions that I think It might help for all of us in the future if we experience a problem like that because even a person who does not eat or drink near mac faced with this problem.Maybe luck,maybe unluck but I think It may happen to everyone. 1)Okay,we waited for 48 hours and we opened our macbook everything seems to work fine but how we will be sure if the water did not damage hard drive,or any small parts of the computer ? Or may It shorten the computers life ? Can water cause damages that we cant see ? How can we be sure about the damage of the computer take ? 2)Water resistant/water proof sleeves:how efficent are they when It comes to protect your computer ?Would it be protecting from the humidity ? 3)Whats the usual testing at genious appointment and how long would it take a normal check ? 4)Are there any programs which shows us If the computer works fine like the day we got ? Those are the questions that came to my mind.I dont know If there any questions that we should ask when a problem like this happens.I do hope that It wont happen to anyone.
