SECTION 1
11. Power Management
CAUTION
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.
Your Fujitsu 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 conditions, 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.
Suspend/Resume/Power On Button
When your LifeBook is active, the Suspend/Resume/Power On button can be used to manually put
your LifeBook into Suspend mode. Push the Suspend/Resume/Power On 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 Suspend/Resume/Power On 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 indicator. 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 Hibernation (Save-to-Disk) mode. (See Hibernation
Feature)
Suspend Mode
Suspend or Standby mode in Windows 98 Second Edition or Me 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/Power On 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 files on which you are working, opens applications
information, and any other data required to support the operations in progress. When you resume
operation from Suspend mode, your LifeBook 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 will not resume.
