Starting Your LIFEBOOK Notebook
Power On
Power/Suspend/Resume Button
The Power/Suspend/Resume button is used to turn on your notebook from its off state. Once you have
connected your AC adapter or charged the internal Lithium ion battery, you can power on your notebook.
To turn on your LIFEBOOK notebook from its off state, press the Power/Suspend/Resume button, located
above the keyboard to the right. When you are done working you can either leave your notebook in sleep
mode, (see “Sleep Mode” on page 56), or you can turn it off, (see “Powering Off” on page 58).
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 notebook will emit
an audio warning and/or an error message will be displayed. (See “Power On Self Test Messages” on
page 96.) 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.
WHEN YOU TURN ON YOUR NOTEBOOK, BE SURE YOU HAVE A POWER SOURCE. THIS MEANS AT LEAST
ONE BATTERY IS INSTALLED AND CHARGED, OR A POWER ADAPTER IS CONNECTED AND HAS POWER.
D
O NOT CARRY YOUR LIFEBOOK NOTEBOOK AROUND WITH THE POWER ON OR SUBJECT IT TO SHOCKS
OR VIBRATION, AS YOU RISK DAMAGING IT.
N
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 96.
