- Power Management
• Allowing the battery to reach the Dead Battery Warning condition.
System memory typically stores the files on which you are working, open application information, and any other data
required to support operations in progress. When you resume operation from Sleep, your system will return to 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.
Hibernation (Save-to-Disk) Feature
The Hibernation feature saves the contents of your notebook’s system memory to the hard drive as a part of the
Power/Suspend/Resume mode. You can enable or disable this feature.
Enable or Disable the Hibernation Feature
The default settings are not enabled. To enable or disable the Hibernation feature, follow these steps:
1 From the Modern Start screen, press [Windows]+[X]. Select Control Panel from the menu, then select Power
Options.
2 Select Choose what the power button does or Choose what closing the lid does, then make your selection (Do
Nothing, Sleep, Hibernate, or Shut Down).
• IF RUNNING YOUR NOTEBOOK ON BATTERY POWER, BE AWARE THAT THE BATTERY CONTINUES TO DISCHARGE WHILE YOUR NOTEBOOK IS IN SLEEP
MODE, THOUGH NOT AS FAST AS WHEN FULLY OPERATIONAL.
• DISABLING THE POWER/SUSPEND/RESUME BUTTON PREVENTS IT FROM BEING USED TO PUT THE NOTEBOOK INTO SLEEP OR HIBERNATION (SAVE-
TO-DISK) MODE. THE BUTTON RESUME FUNCTION CAN’T BE DISABLED.
• IF YOUR NOTEBOOK IS ACCESSING INFORMATION WHEN YOU ENTER THE SLEEP OR HIBERNATION MODE, CHANGES TO OPEN FILES ARE NOT LOST.
T
HE FILES ARE LEFT OPEN AND MEMORY IS KEPT ACTIVE DURING SLEEP MODE OR THE MEMORY IS TRANSFERRED TO THE INTERNAL HARD DRIVE
DURING HIBERNATION MODE.
• THE MAIN ADVANTAGE OF USING HIBERNATION (SAVE-TO-DISK) IS THAT POWER IS NOT REQUIRED TO MAINTAIN YOUR DATA. THIS IS PARTICULARLY
IMPORTANT IF YOU WILL BE LEAVING YOUR NOTEBOOK IN A SUSPENDED STATE FOR A PROLONGED PERIOD OF TIME. THE DRAWBACK OF USING
H
IBERNATION MODE IS THAT IT LENGTHENS THE POWER DOWN AND POWER UP SEQUENCES AND RESETS PERIPHERAL DEVICES.
