Concept Of Hibernation!


Everytime When ever We Switch Off A Computer Or Laptop to Hibernation Mode,Actually We Are Turning Your Computer off but Saving Every Program You Have Been Working on.So when we Turn it Back on,The Computer Will Load Up The Last Program ,Work Windows You Have Opened before You Enabled Hibernate mode.
So What's this Hibernation Mode? How Does This Work?


Hibernation  is a power management mode that conserves power by Shutting down the system. In hibernate mode the current state of the system is saved to the hard drive, and the system will power down.These Current State are Stored in A File Called "Hiberfil.sys" in Your Operating System (Ie.Default C Drive ) And The Size Of This File Would Be Around Or Over 1.5 GB Depending on Number Of Windows Or Programs You Are Working on.To See This Files Goto Folder Options >>Click View >> Choose Show Option And Uncheck the Hide O/s Proteted Files.
usually This File Would Be Availabe At  "C:\hiberfil.sys".
 When a user turns the system power back on, the saved information is read from the hard disk, restoring the last used settings. Hibernate mode is similar to sleep mode, however in sleep mode the power cannot be shut off.


This Hibernate Feature Is Availabe on windows Only  if all hardware is ACPI and Plug-and-play compliant, and additionally all drivers are PnP-compatible. 


On Mac Os X a Feature Called Safe Sleep Works Exactly As Hibernation Saving The Contents To The System Hard Drive and Goes into Sleep.
