Fujitsu T731 manual Power Management

•Selecting “Sleep” after clicking [Start] then clicking the small arrow at the bottom right of the window.

•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 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 Tablet PC will return to the point where it left off. You must use the Power/Suspend/Resume switch to resume operation, and there must be an adequate power source available, or your Tablet PC will not resume.

■IF 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 QUICKLY AS WHEN FULLY OPERATIONAL.

■DISABLING THE POWER/SUSPEND/RESUME SWITCH PREVENTS IT FROM BEING USED TO PUT THE TABLET PC INTO SLEEP OR HIBERNATION (SAVE-TO-DISK)MODE. THE BUTTON RESUME FUNCTION CANNOT BE DISABLED.

■THE SLEEP OR HIBERNATION MODE SHOULD NOT BE USED WITH CERTAIN EXPRESSCARDS. CHECK YOUR EXPRESSCARD DOCUMENTATION FOR MORE INFORMATION. WHEN EXPRESSCARDS 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 TABLET PC IS ACTIVELY ACCESSING INFORMATION WHEN YOU ENTER THE SLEEP OR HIBER- NATION 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 HIBERNATION IS THAT POWER IS NOT REQUIRED TO MAINTAIN YOUR DATA. THIS IS PARTICULARLY IMPORTANT IF YOU WILL BE LEAVING YOUR TABLET PC 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.
