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 brightness. Internal power management for your 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 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 BUTTON

When your notebook is active, the Suspend/Resume button can be used to manually put your notebook into Suspend mode. Push the Suspend/Resume button when your 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. (See figure 2-5 on page 10 for location)

If your notebook is suspended, pushing the Suspend/ Resume button will return your notebook to active operation. You can tell whether or not your system is in Suspend mode by looking at the Power indicator. (See figure 2-5 on page 10) If the indicator is visible and not flashing, your notebook is fully operational. If the indicator is both visible and flashing, your notebook is in Suspend mode. If the indicator is not visible at all, the power is off or your notebook is in Save-to-Disk mode. (See Save-to-Disk Mode)

SUSPEND MODE

Suspend or Standby mode in Windows 98 saves the contents of your 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 notebook 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 notebook’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 notebook will return to the point where it left off. You must use the Suspend/Resume button to resume operation, and there must be an adequate power source available, or your notebook will not resume.

C A U T I O N

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

SAVE-TO-DISK MODE

The Save-to-Disk mode saves the contents of your notebook’s system memory to the hard drive as a part of the Suspend/Resume mode. Your notebook is pre-configured to perform this function. The Save-to-Disk mode can also be configured through the system BIOS to run in other ways depending on what you need to accomplish. (See BIOS Setup Utility on page 33 for more information)
