Power Management

Your Fujitsu LifeBook notebook 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 oper- ating conditions, such as those for the display bright- ness. Internal power management for your LifeBook notebook may be controlled from settings made in your operating system, pre-bundled power management application, or from settings made in BIOS setup utility.

Besides the options available for conserving battery power, there are also some things that you can do to prevent your battery from running down as quickly.

For example, you can create an appropriate power saving profile, put your LifeBook notebook 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 trade-off between performance and power savings.

SUSPEND/RESUME/POWER ON BUTTON

When your LifeBook notebook is active, the Suspend/ Resume/Power On button can be used to manually put your LifeBook notebook into Suspend mode. Push the Suspend/Resume/Power On button when your LifeBook notebook 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.

If your LifeBook notebook is suspended, pushing the Suspend/Resume/Power On button will return your LifeBook notebook to active operation. You can tell whether or not your system is in Suspend mode by looking at the Power icon on the Status LCD Panel. (See Status Indicator Panel on page 13 for more information) If the indicator is visible and not flashing, your LifeBook notebook is fully operational. If the indicator is both visible and flashing, your LifeBook notebook is in Suspend mode. If the indicator is not visible at all, the power is off or your LifeBook notebook is in Hiberna- tion (Save-to-Disk) mode. (See Hibernation Feature)

SUSPEND MODE

Suspend or Standby mode saves the contents of your LifeBook notebook’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 notebook can be put in Suspend mode by:

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

■Selecting Standby from the Windows Shut Down menu.

■Timing out from lack of activity (if the power profile has been set up accordingly).

■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, opens applica- tions information, and any other data required to support the operations in progress. When you resume operation from Suspend mode, your LifeBook notebook will return to the point where it left off. You must use the Suspend/Resume/Power On button to resume operation, and there must be an adequate power source available, or your LifeBook notebook will not resume.

P O I N T

If you are running your LifeBook notebook on battery power, be aware that the battery continues to discharge while your LifeBook notebook is in Suspend mode, though not as fast as when fully operational.

HIBERNATION (SAVE-TO-DISK) FEATURE

The Hibernation (Save-to-Disk) feature saves the contents of your LifeBook notebook’s system memory to the hard drive as a part of the Suspend/Resume mode. You can enable or disable this feature.
