MacBook Pro Is Prone to Condensation!
All right Fellows, I am just sharing my experience about this problem, although I found a lot of complains about it on the web, there may still be someone trying to figure it out what happened to their mac.
All of the sudden my macbook pro didn’t turn on, being located in Brazil, and having to deal with an Apple authorized repair shop with horrible costumers reviews, I decided to open it up and try to have a clue of what was happening, and there it was, signs of humidity on the logic board.
For the fact that I am sure no spill was in question and there were also greenish like mold areas on the board, I knew I was looking at a chronic problem, to be more specific, a condensation problem that had been occurring for quite sometime. I have been living in the south of Brazil (where it is humid and gets cold in the winter months) for one year or so, but that should not be a reason for this kind of problem.
So, after searching the web for a while, I learned that I should remove and clean the logic board with isopropyl alcohol and a toothbrush, so I did it.
I was able to revive my mac but, just yesterday the same problem occurred again, and I followed the same procedure with the same result, Thanks God!
My humble conclusion is that, the Macbook Pro (mine is a 13” mid 2012) is prone to condensation due to its very high operating temperatures (hot air holds more moisture than cold air) caused by its enclosure and low rpm exhaust, plus, its cold aluminum unibody, making a perfect place for condensation to be created.
It is a shame Apple is sacrificing durability over design and quietness. They refused to address the problem and claimed it was due to liquid damage done by a spillage.
I don't mind paying a higher price for something but, I also expect that something to make it worth it. Unfortunately Apple thinks durability is not part of quality!
P.S.: As of right now, system is using about 60% of the CPU, that should be happening because at this time, I only cleaned the logic board from its underside, without removing it from its place. The same happened before, when I had kernel task taking about 90% of the CPU, before I took the logic board out for a complete clean up. The computer restarting by itself is another symptom of this problem.
If anyone would have any idea of how to avoid this problem from coming back, please let me know. I have been keeping my mac inside a closed case, together with a sock full of uncooked rice and a bag of desiccant, and already have macs fan control app set at 35 to 65 Cº.
