Thanks. I'll try that out. Any idea how to disable it so I can do a fresh install?
You should also turn off hibernation. Go to Terminal and type the following command. You will be prompted for your password.
Code:
sudo pmset -a hibernatemode 0
To disable sleep just go to Energy Saver pref pane and slide the Computer Sleep slider all the way over to "Never" for both battery and AC power.
You can still manually sleep the computer from the Apple menu and this does not seem to cause any problems.
