What is the energy difference between sleep and hibernate on your computer?

    The sleep function, commonly known as Standby in Windows, maintains a power supply only to essential and critical components.  All data in physical memory (RAM) is still kept in the internal memory, and the whole system is placed in standby mode.  This allows the computer to be “woken up” and used almost immediately.  The problem is that some power must be kept running for your information to be saved. 

    In Hibernation mode the data is saved to the physical memory (hard disk drive), and the computer is powered off.  When you want to use the computer again, it will boot up and load back the state at the last hibernation.  The advantage of hibernation mode is that you are not using any power when in this mode.  The disadvantage is that it takes longer to restore the state of your computer than in sleep mode.
