50 - Power Management
Your LifeBook notebook can be put in Sleep mode by:
•Pressing the Power/Suspend/Resume button when your system is turned on.
•Clicking the power icon on the lock menu.
•Selecting Sleep from the Windows Shut Down menu.
•Timing out from lack of activity.
•Allowing the battery to reach the Dead Battery Warning condition.
Your LifeBook notebook’s system memory typically stores the files on which you are working, open
application information, and any other data required to support the 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 and Suspend/Resume button to resume operation, and there must be an adequate power source
available, or your notebook will not resume.
•IF YOU ARE 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 SUSPEND/RESUME BUTTON PREVENTS IT FROM BEING USED TO PUT YOUR LIFEBOOK NOTEBOOK
IN SLEEP OR SAVE-TO-DISK MODE. THE RESUME FUNCTION OF THE BUTTON CANNOT BE DISABLED.
•THE SLEEP OR HIBERNATION (SAVE-TO-DISK) 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 (SAVE-TO-DISK) MODE CANNOT RETURN TO
THE EXACT STATE PRIOR TO SUSPENSION BECAUSE ALL OF THE PERIPHERAL DEVICES WILL BE RE-INITIALIZED
WHEN THE SYSTEM RE-STARTS.
•IF YOUR NOTEBOOK IS ACCESSING INFORMATION WHEN YOU ENTER SLEEP OR HIBERNATION (SAVE-TO-DISK)
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 HIBERNATION MODE.
•THE MAIN ADVANTAGE OF USING THE HIBERNATION (SAVE-TO-DISK) FUNCTION IS THAT POWER IS NOT REQUIRED
TO MAINTAIN YOUR DATA. THIS IS PARTICULARLY IMPORTANT IF YOU WILL BE LEAVING YOUR LIFEBOOK NOTEBOOK
IN A SUSPENDED STATE FOR A PROLONGED PERIOD OF TIME. THE DRAWBACK OF USING HIBERNATION MODE IS
THAT IT LENGTHENS THE POWER DOWN AND POWER UP SEQUENCES AND RESETS PERIPHERAL DEVICES.
•YOUR SYSTEM IS SET TO USE THE MAX BATTERY POWER SCHEME WHEN RUNNING ON BATTERY POWER. IF YOU
CHANGE THE POWER SCHEME TO A DIFFERENT PROFILE, YOUR BATTERY LIFE MAY VARY.
