Hibernate vs. Standby

Comparison chart

Hibernate versus Standby comparison chart
Processing Functions Closed and saved to hard-disk Continue to run
Power usage Zero power Lower than normal operations; no power to peripheral components; CPU and RAM continue to run
Resumption Slow Fast
When to use When the system is idle for longer time and rebooting after shut down will be tiresome or inconvenient. When the system will be idle for only a short time; or if the laptop is plugged in to a power source and power consumption is not a concern.


Sleep state (Modern Standby)

In the S0 low-power idle mode of the working state, also referred to as Modern Standby, the system remains partially running. During Modern Standby, the system can stay up-to-date whenever a suitable network is available and also wake when real-time action is required, such as OS maintenance. Modern Standby wakes significantly faster than S1-S3. For more info, see Modern Standby.


Modern Standby is only available on some SoC systems. When it’s supported, the system does not support S1-S3.

Standby Mode

After being in sleep mode for three continuous hours, Mac computers from 2013 or later will automatically enter standby mode. In earlier models, standby kicked in after just one hour of sleep. This mode is essentially a deep sleep for computers using flash storage, as it saves the current state of the session (such as open documents, apps being used and the like) to the internal SSD. Once done, macOS will then power down certain hardware systems, such as RAM and USB buses. The potential length of standby depends on the current battery power, with a fully charged Mac able to remain in standby mode for up to thirty days without requiring a power source.

Mechanical Off state (G3)

In this state, the system is completely off and consumes no power. The system returns to the working state only after a full reboot.

Sleep vs Hibernate vs Standby

What’s the difference between sleep, hibernate and standby? While standby and sleep are actually the same, let us figure out the differences between sleep mode and hibernate mode instead.

While both have the same idea of saving power, they do act differently. Starting with their power consumption, sleep mode will require a bit higher power consumption than hibernation mode simply because it is still technically running. Hibernation mode requires less power simply because the data stored on your RAM is transferred onto your hard drives and so will not require any power after.

On starting up your devices, sleep or standby mode will instantly start up your device without having to go through many processes, unlike your hibernation mode, where it will have to start as if shut down normally. It will however open up your open documents and running applications without starting them again.

Taking the benefits of both sleep and hibernate, the Hybrid-Sleep is one option you can consider instead. It will do the same things as requiring low power consumption, will boot your computer instantaneously and will load up your running documents and applications as they were.

So to sum up, sleep is a low-powered mode where you can instantly start up your computer, and hibernate is a low-powered mode where you can preserve documents and applications that are currently running.

When is it advisable to restart the computer and when not?

Function “Restart” integrated into computer equipment is one of the most used by users. However, very few know when it is really necessary to go for this alternative.

Specifically, restarting a computer, laptop, tablet, etc., should be used when there are bugs in a program , problems with the equipment or even during the put à day or installation of new programs. The reason is that by doing this all the values ​​of your equipment are restored and they restart cleanly.

On the other hand, there are other scenarios where there is no need to reboot . For example, when you do not use your computer for a long time and come back, there is no need to restart it. Remember that this is a function that aims to start the equipment in a clean way.

In case your team hangs up for a moment, it makes sense to wait a few minutes and see if she responds again . Do not proceed directly to the restart, as you may lose all the work you have done. It is better to wait and, if you restart the program, to close it. As soon as you close it you can go on “To restart” .
