Windows 10 lets you put your system to sleep, or hibernate it. Older versions of Windows had these same two options. You can choose to hide both the Sleep and Hibernate option on the power button menu from the Power Plan settings on Windows 10. That said, if you don’t see the hibernate option in the Power Plan settings, it may be because Hibernate is disabled. When hibernate is disabled, the option is removed from the UI completely. It doesn’t appear as a greyed out option. Instead, it just looks as though it doesn’t exist. Here’s how you can fix the missing hibernation option on Windows 10.
Fix Missing Hibernation Option
You can enable hibernation with a command prompt command. You will need administrative rights to enable it. Open Command Prompt with administrative rights. Run the following command. It won’t return anything but it takes only a split second to run and hibernation will be enabled.
powercfg -h on
After you enable hibernation, open the Power Plan options. Right-click the battery icon and select Power Options. Alternatively, open File Explorer and paste the following in the location bar.

Click the Choose what the power buttons do option on the left. Click the Change settings that are currently unavailable option. Enable the Hibernate option and it will start appearing in the Power button menu in the Start Menu.
If you use Hibernate mode, it will take up space on your hard drive. Hibernation works by saving the current state of your system to the hard drive. Normally, this doesn’t add up to more than a few GBs of disk space however it can grow substantially large over time. To fix this, you can turn Hibernate off, and the file will be deleted. You can turn it on right after and continue to use the mode.

If you’re short on disk space as it is, you can use a command prompt command to set the hibernation file size. By default it’s set between 70% – 75%. The following command lets you change it to a different percentage. The percentage is that of your RAM and it cannot be set to less than 50%. You can grow it to 100% if you want, or reduce it to as low as 50% but nothing less than that. If it’s still taking up too much space on your system, consider using the Sleep mode, or shutting down your system instead.
