POWER MANAGEMENT

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 managements for

your notebook mat 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

as appropriate power saving profile, put your

notebook into Suspend mode when it is not

performing as operation, and you can limit the

use of high power devices. As with all mobile,

battery power computers, there is a trade-off

between performance and power savings.

Power/Suspend/Resume Button

When you LIFEBOOK is active, the Power/

Suspend/Resume button can be used to

manually out your notebook into Suspend

mode. Push the Power/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.

If your LIFEBOOK is suspended, pushing the

Power/Suspend/Resume button returns your

notebook to active operation. You can tell

whether the system is Suspended by looking at

the Power indicator. If the indicator is visible and

not flashing, your notebook is fully operational.

If the indicator is visible and fl ashing, your

notebook is in Suspend mode. If the indicator is

not visible, the power is off or your notebook is

in Hibernation mode.(See Hibernation Feature)

* Only applicable for some models

Suspend Mode

Suspend or Standby mode in WIndows 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

button when your system is turned on.

• Selecting Standby from the Windows Shut

Down menu.

stores the file on which you are working you

are working, open application information, and

any other data required to support operation

power source available, or your notebook will

not resume.
