Sometimes you will want the computer to sleep, sometimes to hibernate to save battery. Maintenance can be performed while sleeping, but not in hibernation. However, a computer in sleep mode can be scheduled to automatically wake to perform tasks like checking for emails, syncing, backing up and then it will automatically go back to sleep. Hibernation may appear to be the better option because it doesn’t use any battery on a laptop. When it resumes, it continues exactly as at was before. Unlike sleep mode, no battery is used in a laptop and there is no limit to the time it can spend in hibernation.

Hibernation: The computer saves the current state of the machine to the disk and then turns off the power.

When it resumes from sleep, it carries on where it left off. A laptop battery can last a week or more in sleep mode.

Sleep: When a computer is put into sleep mode, it suspends what it is doing and enters a very low power state.
