Sorry, I just can't resist: http://lmgtfy.com/?q=linux%20hibernation Essentially, hibernation is a method of writing the contents of RAM and the CPU registers to the swap space, then powering down the computer. When the computer comes back on, it reloads the RAM and the CPU registers from the hard drive, and you can carry on from where you left off. This is oversimplified of course, but it isn't necessary to understand the details of how hibernation works in order to use it. Modern distros, including Fedora, will provide hibernation as an option at shutdown time. (I am deliberately avoiding the Gnome 3 flame wars here). This is as opposed to suspend, which preserves the contents of RAM and only writes a little bit of additional information to RAM required to preserve the system state, then shuts down everything except the RAM. This is much faster than hibernation, but it does require that the RAM be kept powered. If you lose the power, your suspend image is lost, but resuming from suspend is much faster than resuming from hibernation. Suspend is very useful on laptops. And both of these as opposed to shutdown, where the contents of RAM are not preserved, and the computer boots again from scratch. --Greg -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
