What is a sample program for hibernation

Windows 10: Power Options - Hibernate vs Standby

The energy-saving options of Windows 10 make it possible to reduce the power consumption of your desktop, laptop or tablet with a few tricks - especially when you are not actively using it. To this end, the operating system offers a few options for customizing the energy saving plans. Some are already familiar with these options, but some will have probably asked themselves what the differences between the individual modes are.

The standby mode - also known as “saving energy”

Standby mode is probably familiar to many. This condition occurs as soon as the PC or laptop remains idle for a longer period of time. The advantage of this is that all work processes are retained in standby and you can continue right where you left off. All program data are stored in the RAM and can therefore be called up again as soon as the computer is used again. This usually happens within seconds and does not require a long wait.

If you are now concerned about what happens when the battery level of a laptop is very low, for example, you don't need to worry about data loss. As soon as this occurs, the computer automatically shuts down and Windows first saves all data on the hard drive. This means that work can be continued at a later point in time when the power supply is connected.

Actually, you don't have to do much to activate standby, other than define the event at which the computer should automatically go into energy-saving mode. To do this, first navigate to the energy options. The fastest way is via the Windows 10 search field or using Cortana. Simply type in “Energy Options” (or speak) and you will get to the relevant options. Otherwise, the whole thing can be reached via the settings as follows: Start -> Settings (small gear in the start menu) -> System -> Network operation & energy saving. Now click on “Additional energy settings” and the energy options will open.

Three scenarios can now be set - pressing the power button, closing the computer or time-controlled. The corresponding settings can be found on the left-hand side in the menu. With the first two methods, you have the option of choosing between four different settings, each for operation in battery mode or on the power cord. You can configure these according to your preferences.

To set an interval after the computer automatically goes into standby, you have to change the corresponding power plan. To do this, click on “Change energy saving mode”. In the following, you can define when the screen should switch off and after how many minutes the computer should go into energy-saving mode. Also again for battery and mains operation.

The hibernation

The hibernation mode is the substitute for shutting down devices that are not used for a long period of time, but on which one is reluctant to go without further work - such as laptops and tablets. Microsoft declares this energy-saving state explicitly for the use of portable devices, which is why it is not even available on many desktop computers.

The state in which the device is located is similar to classic shutdown. The power consumption is reduced to zero, but all active programs and the data are temporarily stored on the hard disk when the system goes into hibernation. This means that when the device is reactivated, the state before the idle state can be restored.

Hibernation can be activated in different ways. On the one hand, the corresponding event can also be defined as with standby - i.e. when closing the computer or pressing the power switch. In addition, hibernation can be activated via Start - Shutdown. To do this, however, the corresponding option must first be activated in the menu.

To do this, simply navigate back to the energy options. Clicking on “Select what should happen when you press the power switch” takes you to the relevant point. Here you can change the settings for the shutdown. If these are grayed out, you must first click on “Some settings are currently not available” in the upper part of the window. Now hibernation can be selected - from now on this will be offered when you click on shutdown.

If you now want to define an action for the idle state, you can do that right here in the same window. Simply select hibernation in the drop-down fields.

The special case: hybrid standby mode

The hybrid standby mode is a special case that extends the advantages of standby with the advantages of hibernation. In addition to the main memory, the data is also written to the hard disk. If the power supply is not interrupted, the data is drawn from the main memory and you can continue working in a few seconds. In the event of a power failure, Windows will access the hard drive and restore the data. The restore process takes a little longer, but you can continue right where you left off.

On many newer Windows tablets or laptops, the hybrid standby cannot be selected at all, as the device creates an automatic backup here if the battery status slips into the critical range. This function is very useful for the desktop, because you benefit from lower power consumption and are also protected against power outages.

To activate the hybrid standby mode, you first have to navigate to the energy options. Here we click next to the corresponding power plan on “Change power plan settings” and in the following window on “Change advanced power settings”. The options window shown in the screenshot now follows, in which the hybrid standby, provided it is supported by your device, can be configured.

When should which mode be used? When should I shut down my computer?

This mode is particularly recommended for laptops and tablets that are used frequently, because less energy is required in standby, as many components such as the processor or the screen are switched off. In addition, if the battery is running low, you don't have to worry about your work.

Hibernation mode is the best choice for laptops and tablets when the computer is not used for a long time and it is uncertain when the next power outlet is nearby. The computer shuts down, saves work on the hard drive and does not consume power in this mode. The advantage over classic shutdown is the ability to continue working.

With floor-standing computers without a battery, standby mode is not the best choice when it comes to data security. This guarantees a quick start after it has not been used, but as soon as the power supply is interrupted, for example due to a power failure, saving the data in the main memory is of little use. In this case, the computer can no longer write the data to the hard disk and thus back it up. Here it is advisable to use the hybrid standby so that work is secured even in the event of a power failure and you can continue right where you left off.

Still, shutting down the computer is the best option in some cases. For example, if the computer is only used very irregularly and rarely - for example only every Tuesday and not the rest of the week. But it is also advisable if you are going on vacation for a longer period of time. If you interrupt the power supply to your desktop computer or want to remove / replace the battery on your laptop, you should first shut down the computer completely. In general, the PC should be shut down before every repair or maintenance measure, be it at home or before sending it to support.
