Let me fix it myself

Problems can occur when the Disk Cleanup Tool disables the hibernation file. The hibernation file must be enabled for the hybrid sleep feature and the hibernation feature to work in Windows Vista. When the hibernation file is disabled and the hybrid sleep feature is enabled, and then you use the hybrid sleep feature, no backup of open programs and open files is saved to the disk. Also, when the hibernation file is disabled, if the computer loses power while it is in sleep mode, open programs and open files will not be recovered after the computer is restarted, and any unsaved work will be lost.

To enable the hibernation feature and the hybrid sleep feature, follow these steps:
