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, 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 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.

*Available on LifeBook models with Windows 98 Second Edition pre-installed.

POWER AND SUSPEND/RESUME BUTTON

When your LifeBook is active, the Power and Suspend/ Resume button can be used to manually put your Life- Book into Suspend mode. Push the Power and 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.

If your LifeBook is suspended, pushing the Power and Suspend/Resume button will return your LifeBook to active operation. You can tell whether or not your system is in Suspend mode by looking at the Power indi- cator. (See Figure 2-8 on page 16 for location) If the indi- cator 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 Save- to-Disk mode. (See Save-to-Disk Mode)

SUSPEND MODE

Suspend or Standby mode in Windows 98 Second Edition or Windows 2000 Professional 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 Power and 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. You must use the Power and 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.

P O I N T

Disabling the Suspend/Resume button prevents it from being used to put your LifeBook in Suspend or Save-to-Disk mode. The resume function of the button cannot be disabled.

C A U T I O N

The Suspend or Hibernation (Save-to-Disk) mode should not be used with certain PC Cards. Check your PC Card documentation for more information.

When PC Cards or external devices are in use, Hibernation (Save-to-Disk) mode cannot return to the exact state prior to suspension because all of the peripheral devices will be re-initialized when the system re-starts.

P O I N T

If your LifeBook is actively accessing information when you enter the Suspend or Hibernation (Save-to-Disk) mode, changes to open files are not lost. The files are left open and memory is kept active during Suspend mode, or the memory is transferred to the internal hard drive during Hibernation mode.
