Hibernate vs sleep What is different?

[passive101]

I noticed there is a hibernate and a sleep function on the acer 5100. What is the difference between these? It seems to spin the hd down on both settings. Which does it do when you just close the lid?

In Windows Vista, 'Stand By' and 'Hibernate' have been combined into an additional 'Sleep' function which is active by default. When chosen, this new 'Sleep" mode saves information from the computer's memory to the hibernation file on disk, but instead of turning off the computer, it simultaneously enters Standby mode. After a specified amount of time (3 hours by default), it shuts down (hibernates). If power is lost during Standby mode, the system resumes from the existing hibernate image on disk. Sleep mode, thus, offers the benefits of fast suspend and resume when in Standby mode and reliability when resuming from hibernation, in case of power loss. Also, in earlier Windows versions, drivers sometimes prevented Windows from entering or reliably resuming from a power-saving state. Windows Vista ensures the availability and reliable resuming from any power state. Applications can disable sleep idle timers when needed such as when burning discs or recording media. Away mode, which is not a power plan by itself but a feature, automatically turns off displays, video rendering and sound but keeps the computer working when the user is away from the computer. Optionally, it can also transition to sleep mode. Power settings are also configurable through Group Policy.

I'm still confused

That's easy...

Hibernate takes a snapshot of everything you got on RAM (including any windows and apps running) and saves it to a special hard disk file and then shuts the computer down, when you resume from hibernation the computer boots a bit faster than a normal power up bootup. This method does not consume any power while the computer is off.

Uses: When you are not going to use the computer for a few hours or more.


Sleep, basically shuts your computer down except some components like RAM, so the next time you resume, it will boot almost in an instant. However, this method consumes battery power.

Uses: When you are just leaving the computer for a few minutes or hours, like at lunchtime or something like that.

I hope I helped you clear that up a bit.

Thanks RayanMX that is helpful.
And my question would be when your lappy goes to Stand By mode is it safe to put it in your laptop briefcase,does it vent stops to work completely?

Ya, I usually put mine into standby instead of Hibernating. I changed settings in ePower so as to not let it go into hibernation after any amount of time in standby. I then keep my laptop zipped up in the bag for many hours or overnight with no problems. I have sometimes left it in standby for a couple of days without a significant battery drain.

One thing though, when i first got this machine, it would have trouble staying in Standby and would come back on without warning. I discovered this issue when i opened my bag after having it in there for about half an hour to find it fully powered, blazing hot and the cooling fan screaming away. (I put it in front of an open window in the winter and it cooled of fast)

That was happening because of a problem with with Dual Core machines and Windows. There was a windows update that addressed it, applied it and never had a problem since. (look back at my old posts for info on the update)

Here's a guide to all the different modes. They mixed up the pros and cons of hibernate, but it's pretty obvious.

sounds like theres no need for standby and hibernate anymore..sleep does it all

That sums it up very well!!!
