How to determine whether a computer supports hibernation and standby features
To determine whether your computer supports hibernation and standby, follow these steps:

Note If the Hibernate tab is not displayed, your computer does not support hibernation.
3. Click to select the Enable hibernation check box, and then click Apply.
Note If the Hibernate tab exists and you click to clear the Enable hibernation check box on the Hibernate tab, the Hibernate option will not appear in the drop-down list on the Advanced tab.
4. In the Power buttons section, verify that the Standby option and the Hibernate option appear in the drop-down list on the Advanced tab.
5. If the Standby and Hibernate options are not displayed, either the computer does not support these features or the power management features are disabled in the BIOS. Contact the system manufacturer for information about the BIOS settings.
