Shut down mode
Before detailing the differences between "Hibernate" and "Sleep," it's helpful to first understand the function of the "Shut down" option. When you click "Shut down," all previously running programs will close. Then, the operating system will stop running on the device, and no power will be consumed. Before "Shut down," it's a good idea to save all files you're working on to avoid losing your most recent work.When the computer is restarted, the boot up process usually takes longer than sleep or hibernate because the PC or laptop must restart the operating system and various programs from scratch.
The length of the boot up process depends on the operating system and the device being used. Computers with Solid State Drives (SSDs) typically boot faster than those with Hard Disk Drives (HDDs). Shut down is best selected if the PC or laptop will not be used for an extended period. This option also allows users to remove the power cord or battery.
Sleep Mode
Unlike Shut Down, the Sleep option still consumes power to maintain program data in memory, preventing it from being lost and requiring a fresh start, as with shut down. Besides memory, other components of the PC or laptop will stop working, so the device as a whole will use minimal power when in sleep mode. In Windows, the Sleep option automatically saves the user's work. When selecting Sleep mode, the user does not need to close all programs on the device.When the computer is reactivated from Sleep mode, the computer immediately returns to its pre-sleep state, without having to wait for it to boot. Users can then resume their work immediately. Therefore, Sleep mode can be used if the user needs a short break and will soon return to work, such as during a meal break or prayer break.
Hibernate Mode
The "Hibernate" option isn't necessarily available on all devices. Alternatively, it may be disabled, meaning it doesn't appear and must be re-enabled before use. Hibernate works similarly to sleep. The difference is that program data isn't stored in main memory (RAM), but rather on storage media (SSD or HDD). The advantage of hibernate is that it consumes less power than sleep because the storage media doesn't need continuous power to prevent data loss (non volatile).Like sleep, hibernate immediately returns the computer to its original state when it's "awakened." However, this process isn't as fast as waking up from sleep because storage media is slower than RAM. Hibernate is suitable for laptops when the user runs out of power but wants to save open programs and documents to avoid having to restart from scratch.
