Long story short....a student of mine gave me her black macbook because her HD crashed and her parents bought her a new MBP. I popped a new HD in and it all works (almost) fine. I had opened it up to clean out some of the hot chocolate she had spilled in it. Now that was the second HD that she had crash on her with that macbook. Is this generally an issue for these? The screen flickers, mostly after it wakes up or turns on for the first time. It flickered before I had the new HD in and installed snow leopard as well. From reading other posts, it seems like this may be the inverter board. Is that a hard fix? OK...discuss. Thanks!
