I have a G4/400 running Jaguar and I was debating wether or not to set it up to go to sleep. I was running Jag. on a 8600 before, so I was unable to use the sleep feature. Now I wonder if it would be a good idea. I usually fire my G4 up when I get home from work at 3:00 or 4:00 PM and leave it on till I go to bed at 10:00 or 11:00. Would the sleep feature extend the life of my hard drive as well as the rest of the components in the system? Or does it make a difference at all? Thanks, Kevin
