The differences between standby and hibernation - which consumes less?

What is the difference between standby and hibernation in the tutorial?

In this video tutorial called The differences between standby and hibernation modes, we will see what are the differences between Standby or Sleep and Hibernate or Hibernate (in English).

We will also see how much the PC consumes, when it is turned on, when it is turned off, but also the Standby and Hibernation consumption. We will also see what is the safest way to feed; Standby or Hibernation?

What are the power states of the PC?

Status Off

As you can see, in this state the PC is turned off. But don't think that it is totally inactive.

In the off state, ie when we close it with the command "Shutdown" in English or "Shutdown" in Romanian, the PC still has certain circuits that are powered. These are for powering some USB ports, for WOL (wake on lan) (WOL on Android) that is, for starting through the network, and others, which, together, consume some electricity.

You will see below the power consumption that in this way the PC still has some energy in it and implicitly a power consumption.

Status On

Obviously, here is the state in which the PC is turned on and 100% functional

Consumption in this state is the highest, as we will see below

Standby or Sleep

In this state the PC saves the working session (open windows, applications, progress in games, etc.) in the ram memory and it shuts down.

In this state the PC is apparently turned off, but because it has to power the RAM, it consumes a little more energy than when it is Off.

Standby advantages

1. The PC shuts down and starts up very quickly
2. The work session is saved in the frame

Standby Disadvantages

1. In case of a power failure, the session in RAM is lost
2. The Standby PC consumes a little more power than when it is turned off

Hibernation or Hibernate

This state is a combination of Off and Standby

It is turned off because it does not consume more energy than when turned off.

It resembles standby because the work session is saved, but not on RAM but on Disk

Hibernation Advantages

1. The working session is saved just like in Standby
2. The PC consumes the same as when it is turned off
3. In case of a power failure, no data is lost
4. As for speed, when you use an SSD, the PC shuts down and starts up quite quickly

Disadvantages Hibernation

1. In the case of PCs with HDD instead of SSD, the stop and start sequences take longer. At the SSD there are no differences between the on / off and hibernation / on times
2. When hibernation on disk is enabled, a space equal to the RAM capacity for working session storage is consumed.

How is hibernation activated?

If you do not have hibernation enabled, it can be enabled in CMD with admin rights by command powercfg.exe /hibernate off

After placing the order, you must go to the Control Panel, in the power settings to check Hibernation, for this command to be present in the shutdown options (SEE IN THE VIDEO TUTORIAL below) or read the instructions on the Microsoft website , about hibernation.

PC power consumption in Standby, Hibernation and Off

I did some tests on my PC. Obviously depending on everyone's PC, the values ​​will be different.

Depending on the features of your PC, consumption may be higher or lower. These values ​​are influenced by the power of the processor, the power of the graphics card, the number of fans, the number of HDD and SSD, the number of RGB lighting installations

On my PC, the configuration is quite minimalist, without a dedicated graphics card, without RGB and without too many fans.

PC consumption off - 2,7 W / h

PC consumption on - 104,5 W / h

Consum PC in Stabdby - 5,9 W / h

PC consumption in Hibernation - 2,9 W / h
