My late 2006 2GHz C2D Macbook has had a host of weird issues lately. Small issues started cropping up right after AppleCare expired, and it has only gotten worse. It started with the palmrest cracking worse that it ever has before (it was replaced 3 times). Then my sleep LED stopped working. Then the LED on my charger stopped working -- and it doesn't seem to be a charger issue, as it has this problem with ANY charger, including the new style ones. The last few days, it has been randomly rebooting itself. No warning, no way to reliably reproduce the issue. Also, the audio crapped out earlier while watching a Flash video. I had to yoink out my speaker cable and put it back in to get it working. If it makes any difference, I've been using it in clamshell mode a lot lately. I'm assuming it's probably a bad logic board, but does anyone have any other ideas?
