Yes. First check the settings on the Advanced tab for Preferences -> Screensaver. There is the option in Power Management to power down your system as one of the settings.I am running Fedora Core 3 on a desktop machine for a while now. The only problem that I seem to be having is that after it has been idle for a while the machine shuts down by itself. Usually the screen saver will kick in and be on for a while and then the machine will just shut down. Other times I am working on the machine and it just shuts down. I am not seeing an error message and the machine starts back up just fine without going through any of the "the machine was shut down improperly" stuff.
Is that enough information for anyone to help?
Second, check your system's BIOS to see if there is a similar setting. Where this is located varies by system.
This should solve the mysterious system powering itself off. -- James McKenzie
