51 - 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.
