Hi, I've got a white macbook from mid 2006, and whenever I close the lid, it spends about 20 seconds getting quieter and quieter and quieter, and then just as it goes to sleep, the CD drive makes an eject noise and it wakes up again. This repeats ad nauseum. If I open the MB after it does this, it just has a black screen until it tries to eject a CD again and then it is fine. I've had to just turn the screen off and leave it open so I can sleep! It was doing this about a year ago, but I thought it had gotten over it. Anyone had the same problem or know what I could do? I've not got a CD in it.
