Getting Started

Starting Your

LifeBook Notebook

POWER ON

Power and Suspend/Resume Button

The Power and Suspend/Resume button is used to power

on your LifeBook notebook, to resume from Standby or

Save-to-Disk mode or to place your notebook in Standby

or Save-to-Disk mode. (You can also use the button to

power down the system by holding it down for approxi-

mately five seconds. This can be useful if the system is

“hung up”. This shouldn’t be used as the normal means of

shutdown, however.) You can also turn off your notebook

by choosing Shut Down from the Windows Start menu.

Figure 3-3. Powering Up the System

Once you have connected your AC adapter or charged

the internal Lithium ion Battery, you can press this

button to power up your notebook. (Figure 3-3)

When you Power On your notebook, it will perform a

Power On Self Test (POST) to check the internal parts

and configuration for correct functionality. If a fault is

found, your notebook will emit an audio warning and/

or an error message will be displayed. (See Power On Self

Test Messages on page 63 for more information).

Depending on the nature of the problem, you may be

able to continue by starting the operating system or by

entering the BIOS setup utility and revising the settings.

After satisfactory completion of the Power On Self Test

(POST), your notebook will load your operating system

BOOT SEQUENCE

The procedure for starting-up your notebook is termed

the Bootup sequence and involves your notebook’s

BIOS. When your notebook is first turned on, the main

system memory is empty, and it needs to find instruc-

tions to start up your notebook. This information is in

the BIOS program. Each time you power up or restart

your notebook, it goes through a boot sequence which

displays a Fujitsu logo until the operating system is

loaded. During booting, your notebook is performing a

standard boot sequence including a Power On Self Test

(POST). When the boot sequence is completed without

a failure and without a request for the BIOS Setup

Utility, the system displays the operating system’s

opening screen.

The boot sequence is executed when:

■

You turn on the power to your LifeBook notebook.

■

You restart your LifeBook notebook from the Win-

dows Shut Down dialog box.

■

The software initiates a system restart. Example:

When you install a new application.

HARD DISK DRIVE PASSWORDS

To provide additional security for your data, you can

assign passwords to your hard disk drive(s). This feature

is managed in the system BIOS Setup Utility. See BIOS

Setup Utility below for information about accessing the

utility

BIOS SETUP UTILITY

The BIOS Setup Utility is a program that sets up the

operating environment for your notebook. Your BIOS is

set at the factory for normal operating conditions, there-

fore there is no need to set or change the BIOS’ environ-

ment to operate your notebook.

The BIOS Setup Utility also allows you to configure such

features as the System Data Security feature parameters,

such as passwords.

When you turn on your notebook be sure

you have a power source. This means that

the battery is installed and charged, or the

AC adapter is connected and has power.

Do not carry the notebook around with

power on or subject it to vibration or

shocks; doing so could damage the

notebook.

Power/Suspend

Resume Button

Never turn off your notebook during the

Power On Self Test (POST) or it will cause

an error message to be displayed when

you turn your notebook on the next time.

(See Power On Self Test Messages on

page 63 for more information)

Remember your passwords. If you set and

forget your User and Master hard disk

passwords, Fujitsu Computer Systems will

not be able to reset it. You may lose data

and have to replace your system board or

hard disk drive.
