Power Management
Your LifeBook has many options and features for conserving battery power. Some of these features are automatic and need no user intervention, such as those for the internal modem. However, others depend on the parameters you set to best suit your operating condi- tions, such as those for the display brightness. Internal power management for your LifeBook may be controlled from settings made in your operating system,
Besides the options available for conserving battery power, there are also some things that you can do to prevent your LifeBook battery from running down as quickly. For example, you can create an appropriate power saving profile, put your LifeBook into Suspend mode when it is not performing an operation, and you can limit the use of high power devices. As with all mobile, battery powered computers, there is a
SUSPEND/RESUME BUTTON
When your LifeBook is active, the Suspend/Resume button can be used to manually put your LifeBook into Suspend mode. Push the Suspend/Resume button when your LifeBook is active, but not actively accessing anything, and immediately release the button. You will hear two short beeps and your system will enter Suspend mode. (See figure
If your LifeBook is suspended, pushing the Suspend/ Resume button will return your LifeBook to active oper- ation. You can tell whether or not your system is in Suspend mode by looking at the Power indicator. See “Power Indicator” on page 13. If the indicator is visible and not flashing, your LifeBook is fully operational. If the indicator is both visible and flashing, your LifeBook is in Suspend mode. If the indicator is not visible at all, the power is off or your LifeBook is in
SUSPEND MODE
Suspend or Standby mode in Windows saves the contents of your LifeBook’s system memory during periods of inactivity by maintaining power to critical parts. This mode will turn off the CPU, the display, the hard drive, and all of the other internal components except those necessary to maintain system memory and allow for restarting. Your LifeBook can be put in Suspend mode by:
■Pressing the Suspend/Resume button when your system is turned on.
■Selecting Standby from the Windows Shut Down menu.
■Timing out from lack of activity.
■Allowing the battery to reach the Dead Battery Warning condition.
Your LifeBook’s system memory typically stores the file(s) on which you are working, open application(s) information, and any other data required to support the operation(s) in progress. When you resume operation from Suspend mode, your LifeBook will return to the point where it left off. To resume operation, you must use the Suspend/Resume button to resume operation, and there must be an adequate power source available, or your LifeBook will not resume.
C A U T I O N
If you are running your LifeBook on battery power, be aware that the battery continues to discharge while your LifeBook is in Suspend mode, though not as fast as when fully operational.
