Hi, I'm doing something that requires my computer to be left on without going to sleep for about an hour. I go into Energy Saver and try to set Computer Sleep to "Never", or at the very least "3 hours". Yet every time I click out and go back, it resets to the default of 5 minutes. I found this out the hard way when I left my computer to go do something, then came back and found out the process was interrupted and the file corrupted. What the #$*#%&) Thanks!
