What Are the Pros and Cons of Hibernating a Laptop? The Myths!

Hibernation on a laptop is a power-saving mode that keeps the computer’s last state. When you wake up your computer after hibernation, you don’t have to reinstall the operating system or reload all of your programs and data.

The pros and cons of hibernating a laptop include:

Pros of Hibernating a Laptop

Hibernate mode is a simple feature found on most modern smartphones. It may take a little longer to switch between modes, but the transition from hibernation to complete “on” couldn’t be simpler.

Hibernate mode has virtually little data risk compared to sleep mode (or simply turning the computer off). Before your hardware is turned off, data is saved in non-volatile memory when you hit hibernation. The data is kept in RAM during sleep mode, which is volatile.

Hibernation uses the least amount of power compared to the other alternatives for putting your computer to sleep for a long time. If you compare hibernation to sleep mode, you’ll notice that it uses very little power.

Cons of Hibernating a Laptop

Below are some cons of hibernating a laptop;

The real downside of hibernation mode is that the computer’s settings are not updated regularly, as they are when a computer is shut down. This increases the likelihood of a problem with your PC requiring a reboot, potentially resulting in the loss of an open file.

Your information can be lost if the power goes off.

Your device wakes up quickly when you switch between sleep and wake modes. Hibernate mode, unfortunately, fails in this location. It may take a few moments to resume your work from hibernation mode. It will take some time because you are essentially restarting your laptop.

Differences Between Hibernating And Sleeping On A Laptop?


To help you save energy, you have three options. You may turn off your computer; you can also hibernate the computer. Finally, you have the option of putting your computer to sleep.

The following are the differences between hibernating and sleep:

  • Sleep mode is power on with the screen and hard disks turned off, whereas hibernation is power off.

  • The RAM chips are regularly replenished in sleep mode to keep their content, and the CPU is turned off.

  • Although waking a laptop up from hibernation is faster than having to start fresh, waking up a computer from sleep is instantaneous.

  • Maintaining hibernation requires no power, whereas maintaining sleep requires a little amount of electricity (as the work is saved in RAM).

  • Both hibernation and sleep are designed to safeguard your documents and programs, which is one of the remarkable similarities between the two.

  • It is unnecessary to reload all applications and data when the computer is turned on from either sleep or hibernate mode.

  • Hibernate consumes less power than sleep, and when you restart your computer, you’ll be just where you left off (though not as fast as sleep). Hibernate your laptop or tablet when you know you won’t be using it for an extended length of time and won’t be able to charge the battery.

Is It Bad To Hibernate A Laptop?

There are three ways to preserve your laptop battery: hibernate, sleep, and shutdown.

The three options have their pros and cons, so it is good to know how they affect the laptop and whether it is bad or good. The use case differs depending on the user; nonetheless, the hibernate mode is completely safe to utilize.

 However, performing a proper shutdown on a regular basis will assist your computer clear RAM and freeing up resources, allowing it to run more efficiently. It can also help you save energy and safeguard your system from power spikes.

Is It Better To Hibernate Or Shut Down A Laptop?

Hibernation is a middle ground between shutting down and putting your computer to sleep. You can call it a shutdown, but it’s actually preserving data from whatever is going on.

Because hibernation consumes so little power, it is also immune to power outages because the data is saved to the hard disk.

To know which one is better between hibernating and shutting down a laptop, we have to look at what both of them entail.

Most of us are familiar with the shutdown state. When you turn off your computer, all open programs are closed, and the operating system is turned off. This power-down option also consumes very little energy, making it an excellent alternative for energy conservation.

It is, however, typically the least time-efficient because you must turn on your computer, go through the boot-up procedure, and wait for startup programs to load each time you wish to use it. Depending on your system, it could take a few seconds or several minutes.

Your computer stores its present state on your hard drive in hibernate mode. When you restart your computer, the state of your computer is stored, including all open programs and data, so you can quickly return to any work you’ve left unfinished. Hibernation takes longer to wake up than sleep, although it consumes far less energy.

If you won’t use your computer much or need to perform maintenance, a shutdown is the best option.

When you know you won’t be using your laptop for a long time and don’t know when you’ll be able to charge it again, hibernation is an excellent option. This is also a fantastic choice for desktop users concerned about power usage because it uses less than sleep mode.

Hibernate mode is usually the best option when you know you won’t be using your computer for an extended period. If you won’t be using your computer for more than 20 minutes, it’s best to put it into sleep mode. It’s also a good idea to turn off your computer if you don’t use it for longer than two hours.

Should you Hibernate, Shut down, or put your PC to sleep?

What Happens When Your Laptop Is In Hibernation Mode?

Hibernate mode is similar to sleep; only it saves your open documents and active applications to your hard disk rather than RAM. This allows your computer to completely shut down, which means it consumes no power when in Hibernate mode.

When hibernation is enabled, RAM contents are written to storage (hard disk, SSD), and the laptop is turned off. When you turn your laptop back on, the initial memory state is read from storage, and all applications appear precisely as they did before hibernation.

Hibernating your computer shuts it down entirely yet allows you to restart all of your work. How so? It freezes whatever you’re doing and saves it in the “Hibernation File” on your hard drive. The computer is then turned off completely, drawing no power from the outlet.

Does Hibernation Damage SSD?

Solid-state drives (SSDs) are a new generation of computer storage devices. SSDs use flash memory, which is substantially faster than a mechanical hard drive.

Hibernation in HDD is essentially a trade-off between power conservation and hard-disk performance degradation over time. A “system hang” can occur if you hibernate any system, resulting in a forced restart. This can kill any system SSD or HDD; the only question is when.

 If you’re running Windows 10 on an SSD, you should disable the hibernate feature to extend the life of your drive. The operating system writes the contents of its RAM to the hibernate whenever it goes into hibernation.

On the other hand, hibernate mode has no detrimental impact on individuals who use a laptop with a solid-state drive (SSD). Nothing breaks because it lacks the moving parts of a standard HDD.
