Your notebook’s system memory typically stores the file on which you are working, open application information, and
any other data required to support operations in progress. When you resume operation from Sleep mode, your
notebook will return to the point where it left off. You must use the Power/Suspend/Resume button to resume
operation, and there must be an adequate power source available, or your notebook will not resume.
Hibernate Feature
The Hibernation feature saves the contents of your notebook’s system memory to the hard drive as a part of the
Suspend/Resume mode. You can enable or disable this feature.

1
From the Start menu, select Control Panel , then select the Power Options icon.
2
Select “Choose what the power button does” or “Choose what closing the lid does”, then make your selections (Do
