66 - Power Management
• Clicking the power icon on the lock menu.
• Selecting Sleep from the [Settings]->[Power] menu.
• Timing out from lack of activity.
• Allowing the battery to reach the Dead Battery Warning condition.
Your Tablet PC’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
Tablet PC will return to the point where it left off. You must use the Power and Suspend/Resume slide to resume
operation, and there must be an adequate power source available, or your Tablet PC will not resume.
• IF YOU ARE RUNNING YOUR TABLET PC ON BATTERY POWER, BE AWARE THAT THE BATTERY CONTINUES TO DISCHARGE WHILE YOUR TABLET PC IS
IN SLEEP MODE, THOUGH NOT AS FAST AS WHEN FULLY OPERATIONAL.
• DISABLING THE SUSPEND/RESUME SLIDE PREVENTS IT FROM BEING USED TO PUT YOUR LIFEBOOK TABLET PC IN SLEEP OR SAVE-TO-DISK MODE.
T
HE RESUME FUNCTION OF THE SLIDE 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 TABLET PC 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 TABLET PC IN A SUSPENDED STATE FOR A PROLONGED PERIOD OF TIME.
T
HE 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.
