Technology is so fragile and precise like clockwork, that the slightest alteration can make everything go haywire.
For some time now, I had the pleasure of trying to diagnose a macbook that would never fall to sleep, or really not wake up either. It was some times impossible to shut down, and once in a blue moon just as hard to start up. Furthermore the cd drive would make weird noises, and the computer in general seemed to be growling. Very odd behavior from a machine.
The great thing about computers is that there is ALWAYS a perfect reason for even the oddest symptoms. In this case I through much research found out, that the USB constantly felt like someone or something unplugged something. Or maybe even plugged something in. In any case, that normally causes the mac to wake up. Or halt whatever it is doing. Which was probably why the whole experience felt a little like driving in heavy rain, on an ice surface buttered up with grease.
By restarting and holding down the apple and s key, the problem became apparent. The computer kept repeating this line:
"IOUSBFamily could not enumerate a device."
I whipped out my screwdriver set and took off the top case, disabled the cd drive and behold: No more growling, or misbehavior.
