Hybrid sleep is a power state that combines sleep and hibernate modes. It writes out all the RAM to the hard drive and then goes into a low-power state that keeps the RAM refreshed. This allows the computer to quickly resume from sleep and, in the case of a power failure, restore from hibernation. Hybrid sleep is off by default on laptops because manufacturers don't want the hard drive to be active for a long time while the system is suspending. However, it can be easily enabled through the Control Panel or by using command-line instructions.

How to enable hybrid sleep on a Windows laptop
Hybrid sleep is a power-saving state that combines the benefits of sleep mode and hibernate mode. It is designed primarily for desktop computers, so it is enabled by default on Windows desktops. If you have a laptop, you will need to enable it manually.
To enable hybrid sleep on a Windows laptop, you need to enable hibernate mode first. Hibernate mode is a power-saving state designed primarily for laptops. It puts your open documents and programs on your hard disk and then shuts down your computer. By enabling hibernate mode, you allow your laptop to enter a low-power state and quickly resume your work.
To enable hybrid sleep, follow these steps:
- Open the Control Panel application by pressing the Windows key + X key at the same time. Then click on Control Panel.
- Click on Power Options.
- Find the power plan you are currently on and click Change plan settings.
- Click on Change advanced power settings near the bottom.
- Expand the Sleep category, then click on Allow hybrid sleep.
- Switch the toggles of both "On battery" and "Plugged in" to "On".
- Click Apply and then OK.
Now, hybrid sleep mode is enabled on your laptop. Simply selecting Sleep in the Power options will directly switch to Hybrid Sleep. It is important to note that hybrid sleep overrides regular sleep, so you will not see a hybrid sleep option listed in the shutdown options. Instead, selecting the regular sleep option in the shutdown settings will activate hybrid sleep.

How to enable hybrid sleep on a Linux laptop
Hybrid Sleep is a power-saving state that combines the benefits of Sleep mode and Hibernate mode. It is designed primarily for desktop computers, so it is enabled by default on Windows desktops. If you have a laptop, you will need to enable it manually.
To enable Hybrid Sleep on a Linux laptop, you must first enable hibernation. This can be done by following a guide such as the one found here: https://askubuntu.com/a/821122/858118.
Once hibernation is enabled, you can set up hybrid sleep. Here is a general workflow for how to do this:
- Suspend to RAM.
- Create a hibernate image (for example, when you shut your laptop lid).
- If you resume with battery power, resume from memory.
- If you run out of battery while suspended, use the hibernate image to resume.
This allows you to never lose your work due to your battery going out. It is important to note that you don't need to have your swap partition space match your physical memory. You only need enough swap space to suspend your current memory usage footprint, which is usually much less.

How to enable hybrid sleep on a Huawei laptop
Hybrid sleep is a type of sleep state that combines sleep and hibernate. When you put your Huawei laptop into a hybrid sleep state, it writes out all its RAM to the hard drive (like a hibernate) and then goes into a low power state that keeps RAM refreshed (like a sleep). This allows you to resume work quickly from sleep, and if there is a power failure, you can still restore the laptop from hibernation.
By default, hybrid sleep is turned off on laptops. Laptop manufacturers requested this because they didn't want the hard drive to be active for a long time while the system is suspending. When a laptop is suspended, it is often closed and put into a bag, and performing large quantities of disk I/O at this time increases the risk of an error.
However, you can easily override this default from the Control Panel. Here's how to enable hybrid sleep on a Huawei laptop:
- Go to the Control Panel.
- Under Power Options, select Change plan settings, then Change advanced power settings.
- Wander over into the Sleep section of the configuration tree and expand Sleep.
- Click on Allow hybrid sleep and select On.
- Go to On battery and select On.
- Click Confirm.
After enabling hybrid sleep, your Huawei laptop will switch to hibernation mode after three hours in Sleep mode. This will help to reduce power consumption and extend your laptop's battery life.

How to convert hybrid sleep to hibernation
Hybrid sleep is a combination of sleep and hibernate modes. It is primarily designed for desktop computers and is enabled by default on them. When you put the computer into a hybrid sleep state, it writes out all its RAM to the hard drive (just like a hibernate), and then goes into a low power state that keeps RAM refreshed (just like a sleep).
Hybrid sleep can be converted to hibernation by simply turning off the power. By comparison, a normal sleep requires resuming the computer to full power in order to write out the hibernation file.
To enable hybrid sleep, follow these steps:
- Open the Control Panel application by pressing the Windows key + X key at the same time. Then click Control Panel.
- Click Power Options.
- Find the power plan you are currently on and click Change plan settings.
- Click the Change advanced power settings option near the bottom.
- Expand the Sleep category, then click Allow hybrid sleep. Then click Apply and OK.
If you want to perform a hybrid sleep, simply enable it, then select the regular sleep option in the shutdown options to activate the hybrid sleep.

How to disable hybrid sleep
Hybrid sleep is a combination of sleep and hibernation modes for desktop PCs. It allows your PC to consume less power when idle. However, if you are experiencing issues with hybrid sleep, you can disable it. Disabling hybrid sleep is a workaround, and your PC will still be able to sleep.
To disable hybrid sleep in Windows 11/10, you can use the Control Panel, the Registry Editor, or the Local Group Policy Editor. Here are the steps to disable hybrid sleep using the Control Panel:
- Search for "Edit Power Plan" in the Windows search box and click on it.
- In the "Edit Plan Settings" window, click on the "Change advanced power settings" link at the bottom.
- In the Power Options dialogue box, under the "Advanced settings" tab, click on the plus sign next to the "Sleep" option to expand the section.
- Again, click on the plus sign next to the "Allow hybrid sleep" option to expand it.
- Select "Off" from the drop-downs next to both the "On battery" and "Plugged in" options.
- Press "Apply" and then "OK" to save the changes and exit.
You can also disable hybrid sleep when your PC is on battery or plugged into a power source by using the Registry Editor. Here are the steps:
- Press Win+R to open the Run prompt, then type "regedit" and hit Enter.
- If the UAC prompt appears, click "Yes" to open the Registry Editor.
- Navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Power\PowerSettings. If you cannot find "Power" and "PowerSettings," right-click on "Microsoft," select "New > Key," and name it "Power." Then, right-click on "Power," select "New > Key," and name it "PowerSettings."
- Right-click on "PowerSettings," select "New > Key," and name it "94ac6d29-73ce-41a6-809f-6363ba21b47e."
- Right-click on this new key, select "New > DWORD (32-bit) Value," and create two values: ACSettingIndex and DCSettingIndex.
- Keep the Value data as 0 to turn off hybrid sleep.
- Do not change the Value data for ACSettingIndex and DCSettingIndex, leaving them as 0.
Disabling hybrid sleep can be done through the above methods. However, it is important to note that disabling hibernation will also disable hybrid sleep. Additionally, if you disable hibernation and a power loss occurs while the hybrid sleep setting is on, you may lose data.
