Fujitsu S6510 manual Standby Sleep Mode

Standby (Sleep) Mode

Standby (Sleep) mode in Windows saves the contents of your system memory during periods of inactivity by maintaining power to critical parts. This mode turns off the CPU, display, hard drive, and all other internal components except those necessary to maintain system memory and for restarting.

Your notebook can be put in Standby mode by:

•Pressing the Power/Suspend/Resume button when your system is turned on.

•Selecting Standby (“Sleep” in Windows Vista) from the Windows Shut Down menu.

•Timing out from lack of activity.

•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 Standby, 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.

■IF RUNNING YOUR NOTEBOOK ON BATTERY POWER, BE AWARE THAT THE BATTERY CONTINUES TO DISCHARGE WHILE YOUR NOTEBOOK IS IN STANDBY 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 STANDBY OR HIBERNATION (SAVE-TO-DISK)MODE. THE BUTTON RESUME FUNCTION CAN’T BE DISABLED.

■THE STANDBY 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 RESTARTS.

■IF YOUR NOTEBOOK IS ACTIVELY ACCESSING INFORMATION WHEN YOU ENTER THE STANDBY OR HIBERNATION (SAVE-TO-DISK)MODE, CHANGES TO OPEN FILES ARE NOT LOST. THE FILES ARE LEFT OPEN AND MEMORY IS KEPT ACTIVE DURING STANDBY MODE OR THE MEMORY IS TRANSFERRED TO THE INTERNAL HARD DRIVE DURING HIBER- NATION 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 HIBERNATION MODE IS THAT IT LENGTHENS THE POWER DOWN AND POWER UP SEQUENCES AND RESETS PERIPHERAL DEVICES.
