Fujitsu NH570 User Guide

44 - Power Management

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

Clicking the power icon on the lock menu.

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 LifeBook notebook’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 notebook will return to the point where it left off. You must use 
the Power and Suspend/Resume button to resume operation, and there must be an adequate power source 
available, or your notebook will not resume.
