I searched the forum, but saw a lot of sleep issues. None quite like mine. I have a MBP 13" bought in June. When I close the lid, it goes to sleep just fine. When I open it, I can hear it start up. The sleep light becomes illuminated, but then about 5 seconds later goes back to sleep. I have tried to hold the power button and shut the computer down, and start it back up. When it starts up, it shows the white screen with the apple logo, then goes blue, and is about to load the log-on screen, and goes back to sleep. I have already tried an archive and install, and a erase and install. Neither worked. Occassionally it will start back up if I just wait 20-30 minutes. Sorry about the long log, but I do not know what information is needed. I tried to wake from sleep around 1:27 in the logs, and it actually let me boot up and log on around 1:53. To give you an idea of what I was doing to cause these logs.
