How to Fix Hybrid Sleep Missing Anniversary Update Issue in Windows 11: Step-by-Step Guide

Hybrid Sleep is a useful feature in Windows 11 that combines Sleep and Hibernate modes to save your work and power efficiently. However, some users have reported that Hybrid Sleep is missing after installing the Anniversary Update. This can cause inconvenience as the system may not enter the low-power state as expected.

Fixing this issue involves checking system settings and making sure the necessary configurations are enabled. The good news is that the solution is usually straightforward and does not require advanced technical skills.

In this guide, we will walk you through the step-by-step process to restore Hybrid Sleep on your Windows 11 device. Each step is explained clearly, so you can follow along easily.

Let’s get started and bring back Hybrid Sleep functionality for better power management.

Quick Note Before You Start

  • Ensure your Windows 11 is updated beyond the Anniversary Update to include the latest fixes.
  • Check that your device supports Hybrid Sleep, especially if you are using a laptop or tablet.
  • Have administrator rights on your PC, as some steps require system-level changes.
  • Save any important work before proceeding, as some steps may require restarting your computer.

Step 1: Verify Power Plan Settings

The first and simplest step is to check if Hybrid Sleep is enabled in your current power plan. Sometimes, the Anniversary Update resets or disables this option.

  1. Press Windows + R to open the Run dialog box.
  2. Type powercfg.cpl and press Enter to open Power Options.
  3. Next to your selected power plan, click on Change plan settings.
  4. Click on Change advanced power settings.
  5. In the new window, scroll down and expand the Sleep section.
  6. Expand Allow hybrid sleep.
  7. Make sure it is set to On for both On battery and Plugged in (if applicable).
  8. Click Apply and then OK.

If the option was missing or disabled, enabling it here often fixes the problem immediately.

Step 2: Enable Hybrid Sleep Using Command Prompt

If the setting is not visible or does not save properly, you can enable Hybrid Sleep manually using the Command Prompt.

  1. Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
  2. Type the following command and press Enter:
    3. powercfg /setacvalueindex SCHEME_CURRENT SUB_SLEEP HYBRIDSLEEP 1
  3. Then type this command to apply the setting:
    4. powercfg /setactive SCHEME_CURRENT
  4. Restart your computer to ensure changes take effect.

This method forces the system to enable Hybrid Sleep on AC power. You can replace /setacvalueindex with /setdcvalueindex to enable it on battery power if needed.

Step 3: Check BIOS/UEFI Settings

Sometimes, Hybrid Sleep can be disabled at the hardware level. To verify this, you need to check your BIOS or UEFI settings.

  1. Restart your computer and enter the BIOS/UEFI setup by pressing the appropriate key during startup (usually F2, Delete, or Esc).
  2. Look for options related to Power Management or Sleep States.
  3. Ensure that S3 Sleep State or any Hybrid Sleep-related setting is enabled.
  4. Save changes and exit BIOS/UEFI.

Hardware-level disabling of advanced sleep states can prevent Windows from showing Hybrid Sleep options.

Step 4: Update Device Drivers

Outdated or incompatible device drivers, especially for display adapters and chipset, can interfere with sleep features.

  1. Open Device Manager by pressing Windows + X and selecting it.
  2. Expand Display adapters and right-click your graphics driver.
  3. Select Update driver and follow the prompts to search automatically for updates.
  4. Repeat the process for System devices and other critical components.
  5. Restart your PC after updates.

Keeping drivers up to date helps ensure Windows can manage power states properly.

Step 5: Run Power Troubleshooter

Windows includes a built-in troubleshooter that can detect and fix common power issues.

  1. Open Settings with Windows + I.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Power and click Run.
  4. Follow the on-screen instructions and apply any recommended fixes.

This tool is helpful for automatically resolving underlying problems affecting Hybrid Sleep.

Alternative Method: Use Registry Editor

If the above steps do not restore Hybrid Sleep, you can try enabling it through the Registry Editor. This method is more advanced and should be done carefully.

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to the following key:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPower
  3. Look for a DWORD value named HiberbootEnabled.
  4. If it exists, double-click it and set its value to 1. If it does not exist, right-click, select New > DWORD (32-bit) Value, name it HiberbootEnabled, and set the value to 1.
  5. Close Registry Editor and restart your PC.

This setting controls the hybrid boot, which can influence sleep behaviors.

FAQs

Why is Hybrid Sleep missing after the Anniversary Update?

The update may reset power plan settings or disable certain sleep states due to compatibility or driver issues.

Can I enable Hybrid Sleep on all Windows 11 devices?

No, some devices, especially tablets or those with specific hardware configurations, may not support Hybrid Sleep.

Is it safe to edit the registry to fix this issue?

Editing the registry can cause system problems if done incorrectly. Always back up the registry before making changes.

Will updating Windows fix this problem?

Often, yes. Microsoft regularly releases fixes and improvements in updates that can restore missing features.

What is the difference between Sleep, Hibernate, and Hybrid Sleep?

Sleep saves your session in RAM and uses a small amount of power. Hibernate saves your session to disk and powers off. Hybrid Sleep combines both, saving to RAM and disk for fast wake and safety during power loss.

When Nothing Works

If none of the above steps restore Hybrid Sleep, consider the following:

  • Check for Windows updates and install any pending patches.
  • Visit the official Microsoft support page for power management issues: Microsoft Support.
  • Contact your device manufacturer for BIOS or driver updates specific to your model.
  • Consider resetting Windows as a last resort after backing up your data.

Conclusion

Hybrid Sleep is a valuable feature for managing power and protecting your work. After the Anniversary Update in Windows 11, it may disappear due to setting changes or hardware conflicts.

By following the steps outlined—from checking power settings and running troubleshooters to updating drivers and adjusting BIOS options—you can usually restore Hybrid Sleep functionality. For advanced users, editing the registry offers an alternative method.

Remember to always keep your system updated and back up important data before making significant changes. With these solutions, you can enjoy efficient power management and quick resume times on your Windows 11 PC.
