Enable Hibernation in Vista
If you somehow managed to switch off hibernation in Vista, probably by deleting the hiberfil.sys file using Disk Cleanup, here’s how to switch it back on.
- Press the Windows key and type cmd followed by Ctrl+Shift+Enter to open in administrator mode.
- Authenticate as an administrator by clicking continue or entering your administrator password (if UAC is enabled).
- In the Command Prompt window, issue the command:
powercfg –h on
- Close the Command Prompt window and restart.
Of course you can switch hibernation back off again by changing on to off in the above command.
