So my brother spilled a cup of milk on his macbook. Its the white older gen from 06' ish. Now i took it apart, how can i tell if the macbooks actually water damaged. Where are the markers that change color? Also, from what i can gather i think the keyboard has ruined but not the motherboard. The charger lights up green when there is no battery, but doesn't if the battery is attached. I tried the original battery and one from my working macbook, does the same thing on both batteries. So it's not that. Im thinking it will start up if i replace the keyboard because it probably got ruined so the power button won't send a signal to the motherboard, therefore wont turn on. I don't want to take apart my working macbook and risk ruining it with static discharge or something, unless theres a good possibility that the keyboard is the problem on the broken one. I see milk residue on the battery prong and around the front left corner. So im assuming the battery ribbon on the macbook and the keyboard itself got ruined. I do not see anything wrong or milk residue on the motherboard or its surrounding components. Any ideas? Also worst comes to worst and it is ruined. What is the best thing to do with it? eBay? Thanks for all helpful input!
