Sleep
Sleep manages power by saving your current working environment to memory and shutting down most
system devices.
Use the Sleep mode, when you want to have a break for few minutes.
Hibernate
Also known as Save-To-Disk (STD) or Save-To-File (STF), Hibernate manages power by saving the
current working environment to an area on your hard disk before turning your system off. It conserves the
most battery power.
Use the Hibernate mode, when you know that you will not use your computer for a while.
