To activate hibernate mode immediately (if available):
1Click Start 
and click the arrow (pointing to the right) beside the lock icon.
2Select Hibernate from the list.
To exit from hibernate mode, press the power button. The computer may take a short time to exit from hibernate mode. Pressing a key on the keyboard or moving the mouse does not bring the computer out of hibernation, because the keyboard and the mouse do not function when the computer is in hibernate mode.
Because hibernate mode requires a special file on your hard drive with enough disk space to store the contents of the computer memory, Dell creates an appropriately sized hibernate mode file before shipping the computer to you. If the computer's hard drive becomes corrupted, Windows Vista recreates the hibernate file automatically.
