A while ago, my macbook was acquainted with a water spill and it began to exhibit a number of troubling symptoms: It would start up, but its screen would immediately shut off and go too dark to see anything. I brought it to someone to fix it and he claimed that if he plugged the laptop into a different monitor, it still worked fine. He said I could use the laptop as a desktop, but if I wanted to use it as a laptop I would need a new logic board. So I got a new laptop. My water-spilled computer sat in the closet for months and then, one day I took it out to get ready and sell it. I was in the process of transferring some data off it (I had restarted and held down T to access it with my newer mac) when after a time, the display shot back to life. I was really shocked and pleased. Unfortunately my good mood was short lived. The Mac failed again, the display disappearing. I want to sell this thing. Im sure someone would find it useful for parts. But I want to be honest about its state so no one buys it thinking they can use it without much trouble. Is there a specific set of problems that follow a waterspill that match up with what I have described above as happening to my laptop, that I can try to explain briefly in an Ebay selling window? I could just write out the whole story, but its specific problem I am unsure of. I was told I need a new logic board, yet the logic board works with a different monitor? That doesn't make sense, does it? So do I just need a new display and the logic board is actually fine? Can someone help me explain to potential buyers what exactly is wrong with the Mac? Many thanks!
