When you Power On your LIFEBOOK, 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 will emit an audio warning and/or an error
message will be displayed. 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

Boot Sequence

The procedure for starting-up your Ultrabook is termed the Bootup sequence and involves your Ultrabook's BIOS.
When your Ultrabook is first turned on, the main system memory is empty, and it needs to find instructions to start
up your Ultrabook. This information is in the BIOS program. Each time you power up or restart your Ultrabook, it goes
through a boot sequence which displays a Fujitsu logo until the operating system is found. During booting, your
Ultrabook 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 Ultrabook.
• You restart your LIFEBOOK Ultrabook from [Settings]->[Power] menu.
• The software initiates a system restart; for example, when you install a new application.
