What does corrosion or burned components look like? I'm really not sure what to look for.Hi Scott:
We combined your threads together here as one thread since they both refer to the same MacBook Pro.
And in addition to what Ashwin told you (great advice), you might look for signs of corrosion which would indicate a spill or water damage.
As with the iPhone and MacBook models release earlier this year, the new MacBooks contain "liquid submersion indicators" or LSI, small patches affixed internally around the keyboard bay that change from white to red when subjected to moisture. These are in place "to help discover accidental damage to the computer," according to sources familiar with Apple's phrasing, but are clearly in place to prevent users from demanding that Apple fix damages caused by liquid spills.
Hi. I just got a used macbook pro on eBay and the seller said all it needed was a new battery. But when I took the bottom off to replace the battery something was telling me that it might have water damage. How can i tell I it does?
