Hybrid Sleep, Sleep, Hibernation Power-Down Options - Windows 10

Hybrid Sleep, Sleep, Hibernation Options/Modes

There are 3 alternate power-down options (besides shut-down and restart) in Windows 10 to suspend your computer -

1. Sleep
2. Hybrid Sleep
3. Hibernation

Sleep Mode

Sleep Mode uses very little power, your PC starts up faster from Sleep, and within seconds of you "waking" the computer, you are taken back to where you left off before engaging Sleep Mode. You don’t have to be concerned about losing your work (windows and apps that were open at the time that you engaged Sleep mode) if the remaining battery power becomes too low, because Windows will automatically save your open screens and apps by turning off the computer if a super-low batter condition is detected.

Use Sleep when you’re going to be away from your PC for just a short period of time. Upon return to your system, press any key or simply move the mouse to wake the system. Please Note: You may be asked for your password at this point to continue.

Hybrid Sleep Mode

Hybrid Sleep mode is designed primarily for desktop computers. Hybrid sleep is a combination of Sleep and Hibernate modes; it places any open documents and programs into memory and onto your hard drive and then places your computer into a low-power state so that you can quickly resume your work upon return.

When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep, so there is no special selection for you to make or setting to change to engage Hybrid Sleep.

Hybrid Sleep is typically turned on by default on desktop computers and off by default on laptops. Check Advanced Settings under Power Options to view the settings.

Hybrid Sleep consumes about the same amount of power that Sleep mode does. Hibernation powers down the computer. One of the advantages of Sleep (and Hybrid Sleep) over hibernation is that external devices (e.g., mobile phones) can still be charged in sleep mode but will not charge in hibernation mode.

To adjust power and sleep settings in Windows 10, go to Start, and select Settings > System > Power & sleep.

• Screen option - select the number of minutes your computer should wait before turning the screen off once the system becomes idle (no user input)
• Sleep option - select the number of minutes your computer should wait before putting it to sleep once the system becomes idle
• Additional power settings - Additional power settings

Hibernation

Hibernation is a power-saving state designed primarily for laptops.

While Sleep puts your work and settings into memory and uses a small amount of power, Hibernation puts your work (like open documents, for example) and apps/programs onto your hard drive and then turns your computer off.

Hibernation uses the least amount of power out of the 3 "standby" options listed in this tutorial. On a laptop, use Hibernation when you know that it will be many hours plus before you will use the system again and will not have an opportunity to charge the battery during that time.

The next time you resume your laptop, the previous session will load into memory, allowing you to pick up where you left off.

Hibernation is not always listed as an option on the shut-down/restart menu screen in Windows 10 by default, but it can be added.

Add Hibernate option in Windows 10 start menu

1. Bring up Control Panel and navigate to Hardware and Sound > Power Options. (press WIN key + X simultaneously to bring up Control Panel). Also, you may want to change the "View" of the Control Panel to CATEGORY.
2. Click Choose what the power buttons do
3. Click the Change Settings that are currently unavailable link
4. Check the Hibernate (Show in Power menu)
5. Click on Save changes

Disable/Re-enable Hibernation - Bring up an Administrative CMD Prompt Screen - then either type or paste (preferred) the following into the CMD screen -

Disable Hibernation -

powercfg.exe /hibernate off 

Enable Hibernation -

powercfg.exe /hibernate on

Fast startup causes hibernation or shutdown to fail in Windows 10 or Windows 8.1 (click on Show tab below)

Fast startup causes hibernation or shutdown to fail in Windows 10 or Windows 8.1
Applies to: Windows 10, version 1903 Windows 10, version 1809 Windows 10 More

Symptoms
When you try to shut down or hibernate the system on a computer that's running Windows 10 or Windows 8.1, the process fails and reverts to the Windows Lock screen.

In this situation, the following event may be written to the System log


Additionally, when you go to the Details tab in this event and then select friendly view, you may notice the following:

Binary data:

In Words

0000: 00000000 00000001 00000000 C004002D
0010: 00002005 C0000034 00000000 00000000
0020: 00000000 00000000

C0000034 - translates to STATUS_OBJECT_NAME_NOT_FOUND

C004002D - translates to IO_DUMP_DRIVER_LOAD_FAILURE

Cause
This issue may occur if Fast Startup is enabled under Control Panel\All Control Panel Items\Power Options\System Settings. When Fast Startup is enabled and a user shuts down the computer, all sessions are logged off, and the computer enters hibernation. As part of the hibernation process, Windows initializes the system's memory dump configuration. If the driver is not loaded, it fails to hibernate, and the event that's mentioned in the "Symptoms" section is logged. This brings you back to the Windows Lock screen.

Resolution
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, go to the following Microsoft Knowledge Base article:

322756 How to back up and restore the registry in Windows
To resolve this issue, check whether event ID 45 is logged in the System log. If you see this event, verify the contents under the DumpFilters registry value:

1. Open the Run box. To do this, press the Windows logo key‌
   
   +R.
2. Type regedit, and then press Enter.
3. Locate and click the following registry entry:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl\
4. From the pane on the right, verify the contents under the DumpFilters registry value.
5. Remove everything and make sure that "dumpfve.sys" is the only value listed.
6. Exit Registry editor.
7. Restart the computer to enable Fast Startup.

Workaround
If you want to shut down the computer without using the Hybrid Shutdown behavior, you can use Shutdown.exe instead. Full shutdown is the default when you use Shutdown.exe, as follows:

Shutdown /s /t 0

The Shutdown.exe command also includes an optional /hybrid parameter that can be used if you want to use the new method:

Shutdown /s /hybrid /t 0

• The Fast Startup setting doesn’t apply to Restart.
• Fast Startup is enabled by default in Windows.
• Disabling Fast Startup is not recommended.

More Information
During Fast Startup, the kernel session is not closed, but it is hibernated. Fast Startup is a setting that helps the computer start faster after shutdown. Windows does this by saving the kernel session and device drivers (system information) to the hibernate (hiberfil.sys) file on disk instead of closing it when you shut down the computer.

When you restart the computer, this typically means that you want a completely new Windows state, either because you have installed a driver or replaced Windows elements that cannot be replaced without a full restart.

Therefore, the restart process in Windows continues to perform a full boot cycle, without the hibernation performance improvement that's described in this article.
