Hibernation is a state you can put your computer in instead of shutting it down or putting it to sleep. When your computer hibernates, it takes a snapshot of your system files and drivers. The Hibernation file can take up lots of space on your hard drive and SSD, even if you never actually put your PC into Hibernation mode. To disable Hibernation, use CleanMyPC. It makes it easy to disable the hibernation file at the click of a button. Launch CleanMyPC and click Hibernation in the sidebar, then press Disable. That all you need to do!
The default sleep mode used by Mac laptops is a hybrid between traditional sleep mode (suspend to RAM) and hibernation (suspend to disk): the contents of the RAM are saved to the disk, but the RAM is kept powered as well. Actually, Deep Sleep lets you pick different sleep modes for when close the MacBook’s lid and activate the widget: standard (suspend-to-RAM only) sleep, hybrid sleep and hibernate. Deep Sleep only works with Mac OS X Tiger 10.4.3 to 10.4.10 and Mac OS X Leopard 10.5.0 (or later, presumably).
By default, 'Sleep' will turn the computer off but my MacBook Pro will still have the white light, switching between dim and bright. In this case, you cannot totally switch off your MacBook Pro as you would like to do in Windows.
However, if you 'Sleep' using your laptop battery, once the battery runs out, MacBook Pro is smart enough to save all contents in your RAM to hard disk. This is called a 'Safe Sleep'.

Wouldn't it be nice if we could choose to hibernate whenever we want so that if we are not using the laptop for a few hours, instead of putting the laptop to 'Sleep', which will still drain the battery, we can 'hibernate' the laptop and restore our applications (as it is) when we start it up again.
Solution
Macworld has an article that contains comprehensive information about this. Here is the summary.
- First find out what is the current setting of your sleep mode, using:
Hibernate For Mac Pro
This will tell you which sleep mode you are currently on. The following displays different sleep mode:
0 - Legacy sleep mode. It will save everything to RAM upon sleeping but does not support 'Safe Sleep'. Very fast sleep.
1 - Legacy 'Safe Sleep'. This is the 'Safe Sleep'. Everything your laptop goes into sleep, it will save everything to harddisk. Slow on Sleep and Startup.
3 - Default. As described above, when sleeping, contents are saved to RAM. When battery runs out, hibernate occurs.

5 - Behaves as 1 but applicable only for modern Mac that uses 'Secure virtual memory'.
7 - Behaves as 3 but applicable only for modern Mac that uses 'Secure virtual memory'.
- For me, I am using MacBook Pro and I know that I am using 'Secure virtual memory' (System Preferences -> Security), so 5 is my choice. I want my Mac to hibernate everything I sleep.
- Make an alias in your .bash_profile under your home directory:
alias hibernateoff='sudo pmset -a hibernatemode 0'
- 'Source' your bash_profile file and your are done!
- Whenever you want to hibernate your computer, if it is not set already, just go to terminal and execute hibernateon. If you want to turn it off, hibernateoff and you are all set.
It was known that if you want to avoid hassle setting up in command line, there is a dashboard widget, called Deep Sleep that will do the trick do. Somehow it does not work on my MacBook Pro.

More information
The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to how much random access memory (RAM) is installed on the computer.
The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate.
