message: and a crack is available for the latest Tiger operating system to enable this feature for much older Mac computers
I doubt cracks should be promoted on Wikipedia. maybe tell it another way e.g: "Altough there are undocumented ways ... or underground patches" if it's semi-legal to apply the "crack", or don't mention it at all.—Preceding unsigned comment added by 132.203.122.76 (talk • contribs) 
: In this case, I would say the crack is not illegal. I'd be better to speak of a patch though. If Tiger is shipped with such a function, it is not illegal to activate it. --Abdull 10:57, 5 June 2006 (UTC)

yes, someone can mention the "Hibernation File Attack"? it describes how the hibernation file can be attacked by malware -> http://web17.webbpro.de/index.php?page=hibernation-file-attack  —Preceding unsigned comment added by 94.245.212.29 (talk) 16:49, 28 February 2009 (UTC)

thread_title:  Hibernation Lock? 

message: What's the pros and cons between shutdown and hibernate ? Which one is better ?
: Some problems people have with hibernation is that the longer a system is operating the more unstable it will become. If you were to use hibernation instead of shutting down every time than memory leaks pile up ect... Also, never ever remove or install hardware while in hibernation. I ended up reinstalling windows because it no longer recognized ethernet or my 56k modem. Some definite pro's for hibernation is if it takes an absurdly long time to boot up or if you are in the middle of a large project.  —Preceding unsigned comment added by 74.75.13.46 (talk) 18:03, 7 April 2008 (UTC)
thread_title:  Shutdown or Hibernate ? 

message: From the intro:
"Hibernating and later restarting is usually faster than closing down, later starting up, and starting all the programs that were running."
and
"Starting from a hibernated state takes a significant time, many seconds or even minutes."
It isn't an outright contradiction, but the use of "significant" makes it seem relative to a normal bootup.  I'd like to remove the second sentence entirely, or qualify it by saying it depends on the speed of RAM and how much RAM was in use when the PC hibernated.Mwv2 (talk) 19:52, 28 September 2009 (UTC)
thread_title:  Contradiction? 

message: Should WIkipedia article include instructions and howtos? For example, there was a short and relatively badly formatted section on how to turn on hibernation under Windows? Besides, it was randomly inserted, breaking flow of text (which clearly continues after the random section with info on Windows Vista). It was unreferenced, and it isn't clear that it referred to XP.
I'm removing it. It can be restored from history. Ivucica (talk) 00:50, 21 January 2010 (UTC)
thread_title:  ...enabling under Windows? 

message: The article states, "If the contents of RAM are also copied to non-volatile storage we have the best of both worlds: if a key is pressed the machine wakes up instantaneously; if the machine is powered down it is effectively in a state of hibernation."
Is this what some OSs, such as Vista and W7, call HYBRID sleep? If so, this should be added.

thread_title:  Hybrid sleep? 

message: This article claims that "After hibernating, the hardware is completely powered down (just like for a regular shutdown).".  This is not true.  After hibernating, the hardware is ALMOST completely powered down, moreso than in a regular sleep state, but it is not completely off.  A small amount of power is supplied to the CMOS/BIOS to keep it in a "hibernation" state, that will force it to load the hibernated hard drive/partition/OS and skip all other BIOS setup options and boot device options.  Try it yourself; hibernate Windows, then try to enter your BIOS setup when you turn it back on (usually by pressing the DEL key on startup).  It won't work.  Now try again; Hibernate windows, but this time, pull the power plug on your computer, remove the battery, and press and hold the power button for 30 seconds to empty the capacitors.  Now you can enter the BIOS setup on bootup!  — Preceding unsigned comment added by Moeburn (talk • contribs) 16:18, 18 September 2013 (UTC)
replies: text: It depends on the machine/bios and OS I guess.  My desktops can have the power removed. I just tried; bios can be entered.  It appears on my desktops anyway, that hibernate is purely software/OS controlled, or the Windows bootloader, because the bootloader does skip the OS selection screen. Probably an ACPI version thing I guess.  66.114.93.6 (talk) 18:11, 16 January 2014 (UTC)
