Sleep Mode - Fujitsu LifeBook E8420 User Manual

Sleep Mode

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 Sleep mode by:
• Pressing the Power/Suspend/Resume button when your system is turned on.
• 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 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.
