Difference Between Sleep and Hibernate ( With Table )

Microsoft provides various options to consume less power for its systems. Microsoft provides three options to reduce power consumption without shutting down your system. Sleep, hibernate, and hybrid sleep are the options gives by Microsoft. It is vital to give some break to your system to make it have better battery life and performance. The computer remains where you are left to sleep and hibernate.

Sleep vs Hibernate

The difference between sleep and hibernate is their power consumption. The sleep uses some amount of power to stores the documents and files in RAM. Hibernate consumes no energy, and it saves on the hard disk. The sleep takes some time to open again compared to hibernate which, takes less time to open the windows. They store data in different places which, makes a difference in consuming power. Sleep is an option that consumes very little power.

The sleep stores the documents and files where you left in the RAM using very little power. Power charging is more harmful to a sleeping computer. The inactive computer produces more heat than the machine in complete shutdown. Sleep is the primary option for both the systems and laptops. The sleep mode is the pausing state of the system. The sleep mode cuts the power to unwanted applications. Most laptops go to sleep default when the system is closed without shutdown.

Hibernate is another provided by Microsoft. It consumes less power when compared to sleep. Hibernate does the same as sleep but, it stores in a hard disk which uses no energy. The hibernate is nothing but a trade-off between the hard disk and power consumption performance. It shows a negative impact for the computers having solid-state drive(SSD). In simple, Hibernate is compress and stores data in the hard disk.

What is Sleep?

The sleep is an option provided to open again the windows where you left off. By pressing the Windows key, X followed by U and S, make your PC go to sleep. Directly choosing the windows icon and press the sleep option to go to sleep in windows. The Alt and f4 are closing the current running window application. The sleep mode is the suspended mode of RAM. When the lid is close, the laptop runs on batteries. It automatically goes to sleep mode. In 1621 IEEE implements the symbol for sleep mode.

If your system runs many applications in backgrounds, it takes more time to go to sleep which causes damage to the RAM. The machine goes to sleep by default when you close the laptop. It is easy to open the sleeping system than the shut downed machine. Pressing any keys will open the computer from sleep mode. Your keyboard and mouse will not permit to open the system in sleep mode in some options.

Sometimes hardware failure is one possible reason for the machine won’t open after sleeping mode. If you’re not going to use your laptop in 10 minutes break, it advises you to shut down the system. The forced shutdown affects the solid-state drive of the system. The system attains more strain when you put the machine in sleep more time. The sleeping mode makes changes in operating systems. The standing-by and suspend are the other names of sleeping mode.

What is Hibernate?

Hibernate is an option to choose to open your windows without consuming energy. The hyberlib is the root file where the operating system installs. Unlike sleep, the hibernate is to save your documents and files on a hard disk. Hibernation implementes in 1992. The Compaq Computer Corporation has a patent for hibernation. If all the device drivers are ACPI can allow hibernation. From the command line or start menu, you can invoke the hibernation.

If you hibernate your system, it booted from the last saved application on the hard disk. It consumes no energy. It helps to memory all the documents on a hard disk and take a break. It can open from where you left off. It affects the system with a solid-state drive. The hibernate compress and stores the data on the hard disk. The system power down like shut down after hibernation.

It is non-volatile storage. Hibernation uses in laptops that use limited memory. The mobile hardware by Google and Apple won’t support hibernation. In Apple operating system, hibernation calls by the mane safe sleep. Like shut down, the hibernation consumes the standby power. Unlike inactive, hibernation has no risk of unplugging the power. BIOS handles the hibernation in early implementation. Modern technologies can control the hibernation themselves.

Main Differences Between Sleep and Hibernate

  1. Sleep consumes some amount of power, and the hibernate consumes no energy.
  2. Sleep takes less time when compared to hibernate, and the hibernate takes more time when compared to sleep.
  3. Sleep is instantaneous and a computer hibernates slow.
  4. The sleep saves documents in RAM, and the hibernate records documents on the hard disk.
  5. Sleep has more chance of data loss, and the hibernate has less risk of data loss.


It is vital to shut down your system at least once a week to makes it better performance. It is not good to maintain sleep or hibernate always. Both the hibernate and sleep will help to open again the windows where you left off. Inactive consumes some energy to save your documents and files. The hibernate consumes no power to save documents on a hard disk.
