Let me fix it myself

This problem occurs for one of the following reasons:
  • The Disk Cleanup Utility was used to delete the Hibernation File Cleaner.
  • The computer does not support the hibernation feature.
  • The hibernation feature is disabled.
  • The Hybrid Sleep feature is enabled.

    NoteThe Hybrid Sleep feature puts the computer to sleep and generates a hibernation file when the user selects the Sleep option in any of the power option menus. Therefore, Hibernate is not offered as a power option when Hybrid Sleep is enabled.

To resolve this issue, use the PowerCfg tool to enable the hibernation feature. To do this, follow these steps.

Note If the computer does not support the hibernation feature, you cannot enable the feature. For information about how to use the PowerCfg tool to determine whether the computer supports the hibernation feature, see the "More Information" section.
  1. Click Start the Start button , type command in the Start Search box, right-click Command Prompt in the Programs list, and then click Run as administrator.

    User Account Control permission If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
  2. At the command prompt, type powercfg /hibernate on.
