Hey guys, i recently poped off the lid off my macbook pro to clean the dust. Coz it is making a what sounds like a dust clogged fan noise, upon cleaning dust from the fans i came upon this: photo (1).JPG


Is this minor water damage?

    Don't know that I'd call that minor, as from the photo, it appears that corrosion as already set in. Definitely appears that a liquid of some sort has gotten in there.

    It's mold/corrosion. How it actually got there is anyones guess. Normally water/moisture.

    Yes i spilled water by accident on my macbook pro before, but only the charger died. My macbook pro survived. But i think i am just using a computer waiting to be no longer be usable. Should i be concerned?

    Yep. Could fail at any time. Corrosion, once started, never sleeps.

    Oops. I'm surprised you didn't short out the circuit card once it got wet. Can't be sure but it looks like there is mold on there. Is it still wet? You might want to take a soft cloth and tamp off the moisture if it is. But be careful.. don't rub.. just tamp it. 


    You could read up on cleaning it.. but only with an apporpaite electronics cleaning solution. If you do elect to clean it up, don't do it with any electrical power attached. Alternatively you could take it to a local Mac repair shop to do this. This is a delicate job since you shouldn't disturb the solder etc.


    I prefer taking it to a shop, btw.


    Oh yeah, don't use water!

    Hm.. Thanks for the advice Russia! I have a friend that does pc repairs, might ask him what to do. I might just wait until it finally dies or something, since it is out of warranty and new MacBook pros are

    Comming out this year. Oh and by the way there seems to be a strange noise comming from the mould position when the computer is turned on, hmmm..... Anyway appreciate the help guys, one of the reasons why I got

    A Mac. U don't see this kind of community in Asus users.

    If you take it on yourself you will have to fully disassemble the logic board and other components. Use a static free brush and I recommend this product:

    Yep.. good point.. forgot about the static thing... should use a cuff on that too.

    Anti Static wrist thingy i have one, and personally i dont think that really mattters. Also the product you recomend i dont seem to know where to get it, i had a look on ebay and no luck. Do you think maybe i should just use a pressurised air duster and blow on that area affected? Dont know if that would do anything



  • Russa Level 4 (1,315 points)

    .. problem with the air duster is that it may spray "frozen" condensation onto the board as you spray. That's nto a good thing.

    You should have a Fastenal in your area look for a location on their web site it's about $20 a can.

    Radio Shack in the US sells a spray can of contact cleaner with a tube and brush dispenser cap. So it should be commonly available.

    "Do you think maybe i should just use a pressurised air duster and blow on that area affected?"

    Never in a million years.  Pressurized air can cause loose particles to become lodged in various nooks and crannies.  A better bet is to use a vacuum cleaner.

    It looks like it isn't beyond hope, although it does look like some corrosion has taken place. A common, though not exactly pro, remedy, is to clean the affected areas with Q-Tips moistened (not soaked) with rubbing alcohol. It's a cheap fix, and does a pretty fair job. If you're concerned about cotton fibers getting caught in your board, Radio Shack does sell special swabs for cleaning electronics. You can also get purer alcohol. Rubbing alcohol is 70% and you can get higher.


    Commercial cleaners are expensive, and can, but don't always, contain extra ingredients that may gum up your works. Just get the thing clean, and chances are the noise may go away too. It looks like the buildup of crud could be causing some slight shorts in the electronics.
