With suspend and hibernate, the computer stores everything that it's currently doing (documents your reading/editing, pages you're browsing, etc), so that when you wake the computer up, you resume from where you left off. Hibernate stores it to hard drive, and the next bootup will read this and resume, automatically. Suspend does it to RAM. So your computer needs (minimal) power continuously available to it, to keep what it's stuffed into memory. If the memory is lost, then the next boot will be a cold boot. When it works, resuming from a suspend can be quicker. Hence why the riskier option exists. Both are security hazards, though. If you have an encrypted system, to protect you against what a thief could do with your data, being able to resume makes it easier for them to crack in. Because resume will only ask you for a log on password, the cold boot decrypt password query was answered, by you, when you originally booted up. Some sort of hardware token, such as a key that must be inserted while booting, but is kept separate from the computer, is the simplest way to avoid that problem. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
