Hibernate vs. Sleep: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 17, 2024
Hibernate involves a deeper, longer power-saving state for computers, while sleep mode allows for quick resumption by keeping data in RAM.

Key Differences

In computing, hibernation is a power-saving state that allows a computer to save its current state to a hard disk, completely shutting down the system. Sleep mode, on the other hand, is a lighter form of power saving where the computer enters a low-power state, keeping the session in RAM.

Hibernate mode is suitable for extended periods of inactivity, as it does not consume battery or power. Sleep mode, however, consumes a small amount of power to keep the session active in RAM, making it ideal for short breaks.

On resuming from hibernation, the computer needs to read the saved state from the hard disk, which takes longer than waking from sleep mode. In sleep mode, since the data is kept in RAM, the system wakes up more quickly.

Data safety is higher in hibernation since the session is saved on the hard disk. In sleep mode, a loss of power means loss of unsaved data, as RAM is volatile.

Hibernate mode requires as much disk space as the RAM size for storing the session, whereas sleep mode does not require additional disk space.

Sleep

A natural periodic state of rest for the mind and body, in which the eyes usually close and consciousness is completely or partially lost, so that there is a decrease in bodily movement and responsiveness to external stimuli. During sleep the brain in humans and other mammals undergoes a characteristic cycle of brain-wave activity that includes intervals of dreaming.

How is sleep mode different from hibernation?

Sleep mode keeps the computer in a low-power state with the session in RAM, while hibernation saves the session to disk and powers down.
