[QUOTE="Ricky B, post: 388120, member: 19624"] Hibernation coppies the contents of the RAM into a section of the hard disk then the PC will go to full power off. I.E not using any power. When the PC is booted again, the data that was in the RAM before hibernation needs to be loaded up and put back into RAM, hence it is slower than mac sleep. It's only dangerous if your PC is poorly configured in that sometimes after you start back up from hibernation, if anything has changed, hardware wise, or if windows thinks it has, it'll just cold reset and boot a fresh, loosing what you were doing before hibernation. Mac sleep is the same as PC sleep, which is different to hibernation: it keeps the RAM modules charged so they hold their data, which is why it still uses power in sleep mode. This is more dangerous than hibernation because if the power is removed while the mac is asleep, or while a PC is in sleep more, the RAM will 'forget' everything. This means when you start up, it'll be a cold boot, and everything you were doing before sleep will be lost. The fact that sleep in the mac world is a lot more stable than sleep on a PC, or hibernation for that matter, is neither here nor there. [/QUOTE]
