- Starting Your LifeBook Notebook

When you turn on your LifeBook 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 LifeBook notebook will

emit an audio warning and/or an error message will be displayed. See “Power On Self Test Messages” on

page 92. 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 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 LifeBook notebook is first turned on, the main system memory is empty, and it needs

to find instructions 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

your operating system is found. During booting, your notebook is performing a standard boot sequence

including a 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 notebook from the Windows Shut Down dialog box.

• The software initiates a system restart. Example: When you install a new application.

DO NOT CARRY YOUR LIFEBOOK NOTEBOOK AROUND WITH THE POWER ON OR SUBJECT IT TO SHOCKS

OR VIBRATION, AS YOU RISK DAMAGING YOUR NOTEBOOK.

EVER TURN OFF YOUR LIFEBOOK NOTEBOOK DURING THE POWER ON SELF TEST (POST) OR IT WILL

CAUSE AN ERROR MESSAGE TO BE DISPLAYED WHEN YOU TURN YOUR LIFEBOOK NOTEBOOK ON THE

NEXT TIME. See “Power On Self Test Messages” on page 92.
