- Power Management
• Allowing the battery to reach the Dead Battery Warning condition.
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.
Enable or Disable the Hibernation Feature
The Hibernate is enabled by default. To disable or enable the Hibernation feature follow these steps:
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
Nothing, Sleep, Hibernate, or Shut Down).
• IF RUNNING YOUR NOTEBOOK ON BATTERY POWER, NOTE 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 MODE.
T
HE BUTTON RESUME FUNCTION CAN’T BE DISABLED.
• THE SLEEP OR HIBERNATION MODE SHOULD NOT BE USED WITH CERTAIN PC CARDS. CHECK YOUR PC CARD DOCUMENTATION FOR MORE
INFORMATION. WHEN PC CARDS OR EXTERNAL DEVICES ARE IN USE, HIBERNATION MODE CANNOT RETURN TO THE EXACT STATE PRIOR TO
SUSPENSION, BECAUSE ALL OF THE PERIPHERAL DEVICES WILL BE RE-INITIALIZED WHEN THE SYSTEM RESTARTS.
• IF YOUR NOTEBOOK IS ACCESSING INFORMATION WHEN YOU ENTER SLEEP OR HIBERNATION MODE, CHANGES TO OPEN FILES ARE NOT LOST. THE
FILES ARE LEFT OPEN AND MEMORY IS KEPT ACTIVE DURING SLEEP MODE OR THE MEMORY IS TRANSFERRED TO THE INTERNAL HARD DRIVE DURING
H
IBERNATION MODE.
• THE MAIN ADVANTAGE OF USING HIBERNATION 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 HIBERNATION MODE
IS THAT IT LENGTHENS THE POWER UP/DOWN SEQUENCES AND RESETS PERIPHERAL DEVICES.
