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.
