(POST) has detected a
problem. See the Power On Self Test (POST) messages to determine the
meaning and severity of the problem. Not all messages are errors;
some are simply status indicators. See “Power On Self Test Mes-
sages” on page 99.
Your notebook appears to
change setup parameters
when you start it. BIOS setup changes

BIOS setup utility.
Your system display won’t
turn on when the system is
turned on or has resumed. You have installed the

Video Problems
The built-in display is blank
when you turn on your Life-
Book notebook. The notebook is set for
an external monitor
only. Pressing [F10] while holding down the [Fn] key allows you to
change your selection of where to send your display video. Each
time you press the keys you will step to the next choice. The
choices, in order are: built-in display only, external monitor only,
both built-in display and external monitor.
The display angle and
brightness settings are
not adequate for your
lighting conditions. Move the display and the brightness control until you have ade-
quate visibility. Pressing either the [F6] or [F7] keys while holding
down the [Fn] key also allows you to change the brightness level
of the display.
Power management
timeouts may be set for
short intervals and you
didn’t notice the display
come on and go off. Press a keyboard button or move the mouse to restore operation.
If that fails, push the Power/Suspend/Resume button. (The display
may be shut off by Sleep mode, Auto Suspend or Video Timeout)
The notebook turned on
with a series of beeps and
the built-in display is blank. Power On Self Test has
detected a failure which
does not allow the dis-
play to operate. Contact your support representative.
