Hibernation saves your session state in RAM while your computer is off. This makes hibernation perfect for laptops because you don’t have to worry about losing your work when your computer goes into sleep mode.
However, there are some drawbacks to hibernating your session. For example, you won’t be able to access your files or run programs while your computer is asleep. You’ll also lose all unsaved changes to documents and open applications.
You might choose to use hibernation because you don’t want to lose unsaved data. Or maybe you’re worried about losing important documents or emails. Or perhaps you just want to free up space on your hard drive.
When you shutdown, your operating system saves information about what programs are open, your active window settings, and your current state of memory into a file called a hiberfile.dmp. Your computer stores this file on your hard drive. When you restart, Windows loads the hiberfile.dmp and restores everything from there.
