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.
The power manage-
ment timeouts may be
set for very short inter-
vals and you failed to
notice the display come
on and go off again.
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 Standby mode, Auto Suspend or Video Time-
out)
The notebook turned on
with a series of beeps and
the built-in display is blank.
Power On Self Test
(POST) has detected a
failure which does not
allow the display to
operate.
Contact your support representative.
The display goes blank by
itself after you have been
using it.
The notebook has gone
into Video timeout,
Standby mode, or Save-
to-Disk mode because
you have not used it for
a period of time.
Press any button on the keyboard, or move the mouse to restore
operation. If that fails, push the Power/Suspend/Resume button.
Check your power management settings, or close your applica-
tions and go to the Power Savings menu of the setup utility to
adjust the timeout values to better suit your operation needs.
